2012 WATER QUALITY STATUS REPORT

A. WATER BODIES AND CLASSIFICATION

Central Visayas region, Region 7, is located at the central part of the Visayas islandgroup with a land area of 15,875 km. It is bordered by the Visayan Sea and the province ofMasbate in the north, Mindanao Sea in the south, Negros Occidental in the west and theisland of Leyte in the east. It consists of four (4) provinces, namely: Cebu, Bohol, NegrosOriental and Siquijor (see figure below). It includes three (3) independent cities namely:Cebu City, Mandaue City, and Lapu-Lapu City. Cebu City is its regional center.

As of the 2010 Census and Housing Population conducted by the National StatisticsOffice, Central Visayas had a population of 6,800,180 making it the 5th most populous of the

country's 17 regions. The census showed an average annual population growth rate of1.77% from 2000 to 2010, significantly less than the national average of 1.90%. The regionseconomic strengths are in exports, tourism, and commerce. It is home to several economiczones, nationally recognized tourist attractions and facilities as well as shipping and tradingcompanies.

Figure 1. Map of Central Visayas

As a whole, the region is hilly and mountainous. The flatlands of the region serve asthe land for farming and other cottage industries. The region experiences little or no rainfallat all because of the mountains that serve as protection against the strong typhoons thatother parts of the country get. But there are times that the region gets affected by strongtyphoons. The land used for farming in the region is not as big as the other regions. Asidefrom palay, the farmers also plant corn, sugarcane, abaca, coconut, tobacco and root crops.They also subsist on fishing because most islands are surrounded by water.

There are also a number of home industries in the region. The people manufacture

bags, fans, placemats and other household things. The food industry includes biscuits andbread, chicharon and other food items that only the region can produce. It is blest withbeautiful beaches, a plethora of sea life, and areas with natural wonders.

Note that some rivers and bays are classified differently in its upstream, midstream,and downstream sections. The figure below shows the breakdown of classified water bodiesin Region 7 according to beneficial use.

Figure 2. Breakdown of Classified Water Bodies

Based on EMBs classification, inland water bodies are classified as follows:

1 Class AA (Cebu); 25 Class A (5 in Bohol, 9 in Cebu, and 8 in Negros Oriental); 15 Class B (3 in Bohol, 6 in Cebu, and 6 in Negros Oriental); 10 Class C (3 in Bohol, 4 in Cebu, and 3 in Negros Oriental); and 1 Class D (Cebu).

For coastal and marine waters, one bay is classified as Class SA, seven bays asClass SB, and three bays as Class SC.

B. WATER QUALITY STATUS

This report provides an overview of the current status of water quality of the region.This latest update relies on the selected indicators of water quality. Indicators are comparedto accepted environmental guidelines and criteria.

There were five (5) rivers and three (3) coastal waters monitored by EMB 7 for theyear 2012, namely Butuanon River in Mandaue City; Sapangdaku River in Toledo City;

These water bodies are valuable assets providing pastoral beauty, wildlife habitatand recreational opportunities to the region. Over the years, water quality in these waterbodies has generally improved substantially with more effective treatment technologies,better land management practices, and increasingly more stringent water quality regulations.Nevertheless, there is opportunity for additional improvement.

Butuanon River and Guadalupe River had been monitored since these are inside theheavily industrialized and densely populated Metro Cebu area. These have extremely highpollution levels in terms of high BOD5concentrations, low oxygen levels, and high coliformcell counts. Monitoring of Butuanon and Guadalupe Rivers were continued to improve thewater quality due to public complaints being biologically dead situated proximate within theurban center of Mandaue City and Metro Cebu.

Rivers in remote rural areas also show significant pollution levels. Both SapangdakuRiver in Toledo and Luyang River in Carmen are contaminated with fecal coliforms.Guindarohan River was monitored in 2012 for the purpose of reclassification because of thecurrent sand and gravel quarrying within the river system.

Aside from the five (5) rivers, for the Beach Watch program, there is monthlymonitoring of Hilutungan Channel specifically in the area of selected Mactan Island Resortsand Maribojoc Bay specifically near San Jose Drainage area in Tagbilaran City, Bohol. TheCoastal Waters of Balamban, Cebu and Toledo City, which is part of the Taon Strait, wasmonitored in 2011 for the purpose of classification/reclassification.

b. Water Quality Monitoring Results and Assessments

Water Quality

Butuanon River is a priority water body for many years. It has been identified tobe designated as Water Quality Management Area (WQMA). Butuanon River isclassified as Class D water body. Monthly water quality monitoring of Butuanon River isbeing conducted at eleven (11) sampling stations since the third quarter of 2011 until2012. The eleven(11) sampling stations include the following: (1) Camboga-ong Bridge,(2) Butuanon Bridge, (3a) Tingub Bridge, (3) Greenhills Outfall, (4) Pilit Treasure Island,(5) Old Pilit (HJR Outfall), (6) Canduman Bridge, (7) Bacayan Bridge, and (8) Sta. LuciaBridge, (9) Binaliw II, (10) Candurang, Pulangbato, and (11) Kalubihan, Talamban.

However the Kalubihan, Talamban station was no longer sampled for the 2nd

until the 4th

quarter since the identified station dries up when there is no sufficient rain.

The parameters monitored were Dissolved Oxygen (DO), Biochemical OxygenDemand (BOD5), Total Suspended Solids (TSS), pH, and Temperature, Total Coliform,Fecal Coliform and heavy metals were monitored. Results of the water quality monitoringare shown in Table 4.

The following data plots show the parameters DO and BOD5for the year 2012. Inorder to provide some orientation for the assessment of the data, the values for 100%DO saturation (typically for unpolluted water bodies), as well as the Class Drequirements for DO (40% DO saturation) and BOD (15mg/L BOD5) are also presentedin the graph.

Figure 5. Average Monthly DO of Butuanon River

.

Figure 6. Average Monthly BOD of Butuanon River

The BOD5 parameter represents the easily biodegradable portion of the waterpollution. Biochemical oxygen demand or B.O.D. is the amount of dissolved oxygenneeded by aerobic biological organisms in a body of water to break down organicmaterial present in a given water sample at certain temperature over a specific time

period. Only 62% of the data met the water quality criteria for Class D in terms of BOD,which is 15 mg/L. Likewise, only 42% of the data collected met the criteria for Class D interms of DO, which is 3 mg/L. Based on Figure 6, BOD5result peaked in the month ofMay with 49.27 mg/L BOD5, which is three (3) times higher than the Class D criteria.

For the year 2012, the average BOD5 concentration for the Butuanon River is30.8 mg/L which is 2 times higher than the standard. Comparing this value for the past 3years, the average BOD5 is much lower than 2011, 2010 and 2009 which were 31.2,201.0 mg/L, 201 mg/L, and 51.8 mg/L, respectively. The significant drop indicates thatthere is great improvement in the water quality of the river.

For the year 2012, the DO, as a correlating parameter of the BOD5, as well didnot reach levels acceptable to DENR Class D water quality standards of 3.0 mg/L for DOfor the months of April, June and November. Only for the months of February, May, July,and September were the DO concentrations above the standard 3 mg/L. The lowestreading was recorded in June and November at 2.55 mg/L.

Pollution Sources and Load Assessments

The following pictures were the middle and downstream portion of the ButuanonRiver. Different sources are contributing pollution in the river.

Figure 7. Pollution Source Discharging to Butuanon River

The picture confirms the high pollution during the year. BOD5values fluctuatingaround 1.0 mg/L and maximum finding of 490 mg/L indicate clearly that the big portion ofpollution is from industrial and domestic effluents. The decrease in the average BOD5indicates that efforts to improving the water quality of the Butuanon River, such as Adopta River/Estero Program, monitoring efforts of EMB, and other similar activities by otherorganizations, had effects on the river. However, the EMB 7 still have to enhance theirefforts in monitoring the locators along the river to further reduce BOD5concentration ofthe river to pass the standard, since it is only those upstream stations that passes theBOD5standard of 15 mg/L.


10/32

Public Health and Ecosystem Concerns

Butuanon River is a highly contaminated water body which is bordering alongdensely populated areas in Cebu City and Mandaue City. There are rivebank areasdownstream which are occupied by informal settlers. For these residents directlyexposed to the river water, health risks are coming from high pollution levels with allkinds of organic compounds (as summarized by the BOD5 parameter). In this way, thepoor water quality of Butuanon River is depriving the residents from their quality of lifesignificantly.

Butuanon River has experienced a general decline in the quality of its surfacewater over the last several years due to development, industrialization, and other humanactivities. Natural phenomena such as typhoons further exacerbate this decline in waterquality by increasing stormwater pollution loading to the water body. This results inblackening of its water, negative impacts to human and has limited the use of our waterresources.

From the ecological point of view, the following data plots below are illustratingthe development of BOD5 concentrations in the different sampling stations alongButuanon River. The plot of BOD5 below shows that the highest BOD5average for theyear, 544.73 mg/L, was from station # 2 Butuanon Bridge. Comparing it with the 2008and 2009 highest BOD5average from station # 1 Camboga-ong Bridge, which were 73.4mg/L and 168.6 mg/L, respectively, the 2010 average is much higher than the 2008 and2009 average. The result also indicates the stations # 1 and 2 are the most polluted partof the Butuanon River.

On the other hand, the most upstream has the lowest BOD 5of 15.33 mg/L sincelesser pollutant sources are located in that station. However, as compared to the 2009data, it is higher this year than last year wherein the Sta. Lucia Bridge Station had an

average of 2.07 mg/L BOD5. This confirms that the most polluted part is the downstreamportion of the Butuanon River. This shows that the river is still far from rehabilitation.

2. Guadalupe River

a. Description and uses of water body

Guadalupe River is a 12-kilometer water body which originates in the mountainarea of Cebu City in Brgy. Sapangdaku and eventually discharges into Mactan Channel.Approximately 8-kilometer length of the river is crossing Cebu City urban area, mostsignificantly the heavily densely populated areas of Cebu City. While the water ofGuadalupe River in the upstream area still can be used for drinking, bathing and forwashing purposes, the middle and downstream portions of the river is used as drainagecanal.


Water Quality

Guadalupe River has been a priority water body for many years. EMB 7 is

conducting quarterly water quality monitoring of Guadalupe River at four (4) samplingstations. The four (4) sampling stations include the following: (1) Topaz Bridge, (2)Sanciangko Bridge, (3) B. Rodriguez Bridge, and (4) Sandayong Bridge. Below arepictures of the sampling stations. The parameters monitored are Dissolved Oxygen(DO), Biochemical Oxygen Demand (BOD5), Total Suspended Solids (TSS), pH, andTemperature. Results of the water quality monitoring are shown in Table 5.

The following data plot shows the parameters BOD5and DO for the year 2011. In

order to provide some orientation for the assessment of the data, the values for 100%DO saturation (typically for unpolluted water bodies), as well as the Class Crequirements for DO (60% DO saturation) and BOD (10 mg/L BOD 5) are also presentedin the graph.

Figure 10. DO and BOD5in Guadalupe River

As for the BOD5parameter, all the recorded data from first to the fourth quarter2011 are higher than the criteria for Class C of 10 mg/L. Data for 2ndand 3rdquartersshow high BOD5values of 85 and 68 mg/L, respectively.

For 2011, the average BOD5concentration for the Guadalupe River is 45. 3 mg/L.For the year 2012, the average BOD concentration is at 57 mg/L. There is a significantincrease as compared to 2011s average BOD concentration.

The DO, as a correlating parameter of the BOD5, did not reach level acceptableto DENR Class C water quality standards of 5.0 mg/L for DO. Results ranged from 0 to 5


13/32

mg/L. Based on Table 5, Only Station 4 (Sandayong Bridge) reached a DO of 5 mg/L,the maximum value obtained which is more than the standard 5.0 mg/L. This indicatesthat only the upstream portion of the river passes the water quality criteria for Class C.Both results of BOD5 and DO show that the river is still polluted, thus should beimproved.

The figure below shows the BOD5concentrations of the four (4) sampling stationsfor each quarter for 2012.

Figure 11. Quarterly BOD5in Guadalupe River

The average DO and BOD5of Guadalupe River for 2012 is 0.81 mg/L and 56.7

mg/L, respectively. The results this year is less than the results last year for DO. Further,a significant increase can be observed for BOD5with last years result at 55.3 mg/L.Thisindicates that the quality of river has degraded which requires mitigating plans torehabilitate the quality of the river.


The Guadalupe River is contaminated with domestic wastewater since the area isdensely populated and households lack adequate septic tanks and there is nocentralized wastewater treatment facilities for such domestic wastes. The two identifiedmain reasons for the deterioration of the river water quality are the abundant dischargeof household wastewater and the inadequate disposal practices for solid waste. A further

growing population leads to the development of new residential areas situated alongriverbanks of Guadalupe River. Commercial or industrial pollution sources are notconsidered as significant along Guadalupe River.


Guadalupe River is a highly contaminated water body which is bordering alongdensely populated areas in Cebu City. For residents directly exposed to the river water,health risks are coming from high pollution levels with all kinds of organic compounds (assummarized by the BOD5parameter). In this way, the poor water quality of Guadalupe

River is depriving the residents from their quality of life significantly. It should also benoted that the bigger part of the river is already anaerobic, which shows clearly that theriver is still far from rehabilitation.

3. Luyang River


Luyang River is a 20-kilometer water body which originates in the mountain areain Carmen, Province of Cebu and eventually discharges into the eastern coastline ofCebu Island. The river encompasses a scarcely populated provincial area. The water ofLuyang River is used for drinking (particularly the upstream) and for washing purposes.In the downstream portion the river is also receiving wastewater of a chemical industry.Below are pictures of the Luyang River Watershed and the four (5) sampling stationsalong the Luyang River. From Cantipay, Carmen and upstream of the Luyang River isclassified as Class A while from Cogon, Carmen to downstream is classified as Class C.

Water Quality

EMB-7 started monitoring of Luyang River in 2005 for the purpose of protectingthe water body for its potential use as water supply for Metro Cebu. Quarterly waterquality monitoring of Luyang River is being conducted at five(5) sampling stations. Thefive (5) sampling stations include the following: (1) Luyang Bridge, (2) Back of ShembergBiotech, (3) Obayong Bridge, and (4) Cantumog Spillway and (5) Brgy. Cantipay. Therewas no sampling during the fourth quarter since the vehicle allotted for the samplingactivity was repaired and is not yet serviceable until early January 2012. The parametersmonitored are Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD5), TotalSuspended Solids (TSS), pH, Temperature, Total Coliform, and Fecal Coliform. Resultsof the water quality monitoring are shown in Tables 6 and 7.

In terms of BOD5 and DO concentrations, there is generally no significantpollution levels observed. The BOD5and DO concentrations for all the stations from the1st quarter until the 3rd quarter complied with the standards for Class A waters.Compared to 2011s monitoring, there has been improvement in the quality of theLuyang River.

The total and fecal coliform was monitored for the month of September andFebruary however, results cannot be compared with the standards since these values

refer to the geometric mean of the most probable number of coliform organism during a3-month period.

The observed contamination in terms of the total and fecal coliform in theupstream portion of Luyang River for months of February and September has to benoted to be alarming particularly when considering the rivers rather rural location.Pollution sources in the upstream are poultries, piggeries, residents, and small scalefarming (e.g. goat and carabao) present in the area. Most people residing in the arealives in houses made of wood or nipa and not concrete. It is possible that thecommunity in the upstream portion do not have enough sanitation facilities doescontaminating the river.


The water of Luyang River poses health risk to residents who are using the waterdirectly for drinking without prior treatment. For residents directly exposed to the river

water, health risks are coming from the coliforms (as summarized by the coliform cellcounts). If ever the water body would be used as water supply for Metro Cebu in largescale, further measures in order to improve the quality and protect it from furthercontamination have to be applied.

4. Sapangdaku River


Sapangdaku River watershed is located in the west central side of Cebu Island. Itcovers the political jurisdiction of Barangays Daan Lungsod, Dumlog, Sangi, Ilihan,Canlumampao and Magdugo of the City of Toledo, Cebu. Sapangdaku River is a ratherextensive water body which originates in the mountain area around Toledo andeventually discharges into the western coastline of Cebu Island. It stretches to about 9kilometers starting from its mouth in Brgy. Daan Lungsod to its upstream point at Brgy.Magdugo. It mostly encompasses a scarcely populated provincial area. It has tributary

rivers that pass the Atlas Copper Mining Area mining site like the Hinulawan River andIlag River. However, due to the nearby location of the Atlas Copper Mining Area, thewater body is affected by both industrial and domestic discharges. It is classified asClass A in the upstream of Cantabaco and Class C downstream of Cantabaco.

Below is a picture of the Sapangdaku River System and the four (4) samplingstations.

.

Figure 21. DO and BOD5in Sapangdaku River

In terms of BOD5 and DO, there is generally no significant pollution levelsobserved for Sapangdaku River. All samples passed the BOD and DO standards. Theannual average BOD5was 1.69 mg/L and DO was 5.9 mg/L which passed the standardsfor BOD5 and DO standards for Class C which are 10 mg/L and 5 mg/L, respectively.The BOD5and DO concentrations did not prove to be an issue in the area.


For the year 2012, monitoring results shows there is no risk as to the water

quality of the whole river. However, results form the monitoring conducted last yearshowed that during the 2nd quarter, the DO level was below the 5mg/L minimumstandard.

5. Guindarohan River


The Guindarohan River watershed is located in the in Minglanilla, Cebu. It is arather extensive water body which originates in the mountain area around Naga andMinglanilla and eventually discharges into the eastern coastline of Cebu Island. Itstretches from its mouth in Brgy. Lower Minglanilla to its upstream point at Brgy. Cantao-an, Naga. It mostly encompasses a scarcely populated provincial area in the upstreamand populated rural area in the downstream portion. It has tributary rivers, the Matun-ogRiver and Naupa River located in the upstream portion of Guindarohan River. However,due to the sand and gravel quarrying in the river system, the water body is affected byboth industrial and domestic discharges. It is classified as Class A in the upstream ofCantao-an, Naga (Station 3 to 7) and Class C downstream of Cantao-an, Naga (Station1 to 2).

Water Quality

The following data plot shows the total coliform and fecal coliform cell countsalong the eastern Mactan Island coastline for the year 2012.


23/32

.Figure 24. Total and Fecal Coliform at Mactan Island Resorts

From the plot, it is shown that it was on during the months of April, July andNovember wherein the total coliform was above the standard for Class SB which is 1,000MPN/100 mL. Compared to last years monitoring, it was only in December 2011 that thetotal coliform result was above the standards. Based on Figure 27, the lowest totalcoliform count was recorded in October with a value of 83 MPN/100 mL. In 2011, thelowest was 63 MPN/100 mL which was obtained in September.

On the other hand, for fecal coliform cell count, it is also for the months ofJanuary, April, May, June, July, November and December wherein the results exceeded

the fecal coliform standard of 200 MPN/100 mL for Class SB. The highest recordedresult was for the month of July with a result of 41467 MPN/100 mL while the lowestfecal coliform was recorded on October at 44 MPN/100 mL.

In 2011, the highest recorded result was on December and the lowest recordedresult was in September.

The total and fecal coliform cell counts for this year can be considered alarmingas international tourists surely would not like to hear that the water they are going toswim at is contaminated with fecal coliform and not complying to the national standards.The coliform contamination in the area needs to be addressed since the current qualityof the beach is still not complying with the standards in certain months.

The tables below show the total coliform and fecal coliform of each samplingstation per month. This tells us which sampling point has the higher total and fecalcoliform cell counts.

Based on the tables above, it can be seen that the higher results of total andfecal coliform cell counts where the samples collected from Tonggo Beach, PalmeraBeach, Palm Beach,for the month of July, which are over the standards for Class SB.The highest total coliform result was 1.6 E+06 MPN/100 mL from the Parker and

Palmera Beaches, The highest fecal coliform result was >1.6 E+06 MPN/100 mL fromthe Parker and Palmera Beaches as well.

Although the values of the monitoring results this year were not as high as lastyear, these values are still very alarming since the highest recorded data are muchhigher than the standards, specifically for the Parker and Palmera Beach areas.


25/32

.Figure 25. Total and Fecal Coliform at each Mactan Island Resort

The geometric mean for total Coliform shows that Cebu Marine Resort, ParkerBeach, Palmera Beach, Palm Beach and Tonggo Beach sampling stations did not passthe water quality criteria for Class SB. In terms of violating the fecal coliform standard forClass SB of 200 MPN/100 mL for the whole year 2012, only Parker Beach, PalmeraBeach, Palm Beach and Tonggo Beach sampling stations failed (geometric mean data).This may be attributed to its location that forms a bay wherein considerable stagnant

water develops during low tide and most of these are public beaches.


The contamination with fecal coliforms comes from run-offs from septic tanks andother domestic sources. In the case of Mactan Island, the resorts and hotels have to beaccountable for this since these are the ones discharging large amounts of effluents.However, there are also local residents living in the area which may have contributed tothe contamination especially the public beaches such as the Parker, Palmera and PalmBeaches.


Fecal coliforms are by far the most significant parameter when it comes toassessing the quality of recreational water bodies, where there is direct intensiveexposure of the skin. Swallowing of water also cannot be avoided at these areas. So, theobserved fecal coliforms counts have to be assessed as alarming and have to bemitigated by improved sanitation and wastewater treatment.

2. Maribojoc Bay (San Jose Drainage)



26/32

The coastline of Tagbilaran City is the Maribojoc Bay. The water body is used fortourism purposes like swimming, bathing, etc, as well as transportation and fishing. Inthis way, the desirable water quality in the area according to DAO 34 would be Class SB.Monitoring of Maribojoc Bay is part of the Beach Ecowatch Program of EMB7. Monitoringin this area was done because of the existing drainage canal leading to the bay. Below isa picture of the coastline of Tagbilaran City.

The following data plot shows the total coliform and fecal coliform cell countsalong the Maribojoc Bay (Tagbilaran City coastline) for the year 2010.

Figure 26. Total and Fecal Coliform at Maribojoc Bay (San Jose Drainage)

From the plot, it is shown that all the months or sampling the total and fecalcoliform cell counts were above the standard for Class SB which is 1,000 MPN/100 mL

and 200 MPN/100 mL. Based on the graph, all results are very much higher comparedto the standards, the highest geometric mean result being obtained in the month of Aprilwith a value of 494,857 MPN/100 mL total coliform and 279,096 MPN/100 mL fecalcoliform. The lowest geometric mean result obtained was 3,903 MPN/100 mL totalcoliform and 3,492 MPN/100 mL fecal coliform in August.


The contamination with fecal coliforms comes from run-offs from septic tanks andother domestic sources. In the case of Maribojoc Bay, the community were the drainagecanal came from have to be accountable for this since these are the ones dischargingwastewater into the canal. However, there are also local residents living in the area

which may have contributed to the contamination.


The total and fecal coliform cell counts results can be considered alarming astourists and the community surely would not like to hear that the water they are going toswim at and go fishing is contaminated with coliforms and not complying to the nationalstandards. The coliform contamination in the area needs to be addressed since thesituation had worsened.

C. Water Quality Management


28/32

a. Legal and Policy

The wastewater charge system of Section 13 Article 2 of DAO 2005-10 is thebasis of computing payment to the government for discharging wastewater into the waterbodies. The discharge fee is computed based on the net waste load following theformula prescribed in Rule 13.1. The priority pollutant parameter for its implementation isBOD or TSS.

Under this permitting system, the Regional office is able to regulate thedischarges from point sources and issues Discharge Permit pursuant to Section 14 ofthe same DAO. The water quality standards are based on the Revised Water Usage andClassification/Water Quality Criteria of 1990 (DAO 34). The effluent standards are stillbased on the Revised Effluents Regulation of 1990 (DAO 35).

b. Update on Compliance and Enforcement

A total of water 268 firms had been issued with Discharge Permits, 291 firms had

been inspected/monitored, and 18 new firms were surveyed during the year.

INDUSTRIAL COMPLIANCE STATISTICS FOR 2011

Category No. of FirmsFirms inspected 257Firms monitored 34

Firms with renewed Discharge Permit issued 220Firms with new Discharge Permit issued 48

NOV issued (inspection, monitoring and survey) 43

Programs and activities to control water pollution and protect water bodies arespearheaded by various government agencies, primarily EMB Region 7. Current

programs implemented by EMB include: Industrial Eco-Watch Program, and Beach Eco-Watch Program.

There is strict monitoring of firms along Butuanon River. Cebu City governmentsconducts regular clean up of Guadalupe River and there is strong enforcement ofEcological Solid Waste Management Act.

c. Investment in Sanitation, Sewerage, and Wastewater Treatment

Metropolitan Cebu Water District, through the assistance of USAID had alreadyidentified the possible area in which they will cater for the project on SeptageManagement through the installation of a Septage Treatment Plant, as one of theirmandates as a water concessionaire. The MCWD is still awaiting the response of theLGU, where the STP will be established, for them to start the project up until now since2011.

Lapu-Lapu City had installed a Sewerage Treatment Facility in the sitio ofBarangay Basak in Lapu-Lapu City, which was designed and constructed by JV BaringConsultants and Allied Services.

3. Guadalupe River Rehabilitation

The Guadalupe River Management Council is now established under theCebu City Rivers Management Council and had been conducting regular meetings.An action program for the Guadalupe River Rehabilitation for the year 2010, 2020,and 2030 was already drafted covering the policy/ legislation/ enforcement,advocacy/ public education, environmental management, research and developmentand resources generation, mobilization and management.

On September 18, 2010, an event entitled Cebu Great River Clean Up wasinitiated by EMB 7, in which the pilot site was the whole stretch of the GuadalupeRiver, including its tributaries / nearby creeks and esteros. On that day, the Adopt-a-River, Adopt-a-Barangay was launched, which was proposed and initiated by EMB 7and accepted and supported particularly by the Cebu City Govt., Cebu Uniting forSustainable Water, Cebu Chamber of Commerce, Cebu Volunteers for GoodGovernment, Aboitiz Leaders of Excellence, Rotary Clubs, Zonta Clubs of Cebu,Metro Cebu Water District, University of San Jose Recoletos, SouthwesternUniversity, University of Cebu, University of the Philippines, St. Theresas College,Vicsal Development Corp. (Gaisano Metro), Vicsal Foundation, Inc., Cebu PrivatePower Corp., Chong Hua Hospital, Qualfon Phils., Inc., Robinsons Land Corp., LuckyTableware, and Elizabeth Mall. Among others, the partner companies have donated

cleanup materials to the barangay as their initial concrete support. Nine (9)barangays were the first recipients of this project.

4. Butuanon River Rehabilitation

The Butuanon River Watershed Management Board (BRWMB) is now reactivatedand had been conducting regular meetings. The Soil and Water ConservationFoundation, Inc. had initially informed the board of the project they will have forButuanon River which is funded and supported by the Coca-Cola Foundation,Atlanta. The project is entitled Butuanon River Watershed Development Projectwhich will be formally launched early 2011.

5. Adopt-an-Estero/ Waterbody Program

As of last quarter of 2012, there have been already thirty-two (32)

D. Best Practices and Lessons Learnt in Water Quality Management

More firms within Mactan Economic Zone (MEZ) are tapping their wastewater tothe centralized Sewage Treatment Plant (STP) of MEZ 1 and Aboitiz Land, Inc. The firmspractice recycling of treated wastewater and use if for the flushing of toilets and wateringof plants.

This year, the Metropolitan Cebu Water District with the aid of AsianDevelopment Bank, had conducted a series of stakeholders workshops on May 18 -20and July 18-20, 2010 for the Mananga-Kotkot-Combado Lusaran River Basins in CentralCebu, Philippines under the Regional Technical Assistance 6470: Managing Water inAsias River Basins: Charting Progress and Facilitating Investment, in which one of thestakeholders who participated is from EMB 7.

In 2010 the EMB 7 personnel have participated in the JICA-funded Orientation-Workshops on Capacity Development Project on Water Quality Management. TheOrientation-Workshops included the following: Development of Industry-Specific EffluentStandards for Hotels and Restaurants Sector, Finalization of Discharge Permitting andWastewater Charge System, Revision of Guidelines for PCO Accreditation andCompliance Inspection Manual, Water Quality Management Area Action Planning,Enhancement of Database for the Water Quality Management Information System,Water Quality Management Implementation Enhancement of Proposed Water QualityManagement Fund Guidelines, Policy Study for Effluent Management, Revised

The EMB Region 7 personnel are task to monitor not only the identified water bodiesin the region but also attending to various industries and other establishments that operate inthe area to ensure compliance. At present, there are only nine (9) field inspectors and two(2) water quality inspectors under the Pollution Control Division. The load entrusted to eachemployee can be extremely daunting.

Aside from the limited personnel resources, EMB 7 personnel need training insurveillance and monitoring, quality testing and analysis, and data analysis. Training couldhelp establish a more standardized system of monitoring that will produce credible data andserve as basis for policy formulation. However, the major constraint is the budget allocatedby the government to the EMB is not even sufficient to sustain water quality managementactivities.
