1, The Project

While Maynilad dramatically improves its water services in the last six {6) years, the companyis now focusing acceleration of its investment* in the wastewater service improvementsunder the west concession area. The Ayala Southvale Village located in Bacoor, Cavite havingturned over its wastewater faciffties to Maynilad is now geared towards a sustainablewastewater solution to make life in the Eocality with quality, environmentally safe andhealthy.

In 1997, Maynilad Water Services, Inc. [MWSI) signed a 25-year concession agreement withthe Metropolitan Waterworks and Sewerage System (MWSS) to provide water andwastewater services to the 17 cities and municipalities comprised in the West Zone of theGreater Metro Manila Area. The areas included are Caloocan, Las Pinas, Malabon, Manila,Muntinlupa, Navotas, PasayH Parafiaque, Valenzuela, parts of Quezon City, a part of Makati,Cavite City, and the municipalities of Rosario, Imus, Noveleta, Bacoor, and Kawit fn Cavite.From 2003 to 2005, MWSI has implemented the Manila Second Sewerage Project (MSSP)through a rehabilitation and enhancement program, which includes improvement of theTondo Pumping Station and the Dagat-dagatan Septage Treatment Plant,

In August of 2009, water operations of Ayala Waterworks in Ayala Alabang and Southvalewere turned-over to Maynilad Water Services Inc. This included all wastewater facilitiescatering Ayala Alabang and Ayala Southvale. immediately, a rehabilitation plan was made inorder to improve wastewater services in ihe area and prepare these facilities for IMScertification. In July 2013, rehabilitation of the Alabang STP took place. The project will becompleted by December 2012, Following this project will be the rehabilitation of the AyalaSouthvale STP's. Rehabilitation of the two facilities will be done in order to provide structuralintegrity to the facility as well as to improve effluent quality, making sure that it meets therequired standards for Class C water.

The two (2) STP's located in Ayala Southvale were constructed in 2000 in order to cater thewastewater demands of the village which is located in Bacoor, Cavite. Each STP has a designcapacity of 31,25 cubic meters per day. These facilities use the dipped-membrane activatedsludge process in treating wastewater within Ayala Southvale Village, Prior to its turn-over, itsoperations were handled by Ayala Waterworks.

Receiving bodies will also be monitored to determine the effect/improvement in the waterquality. Implementation of the project will definitely enhance the water quality of thereceiving creek, a tributary to the Laguna de Bay.Basically, the project will;

• Improve wastewater services in the area

• Improve operational efficiencyof the facility• Improve water quality of the creek and its receiving bodies of water• Improve public health

1,1 Project Rationale

Thereare two (2) existing SewageTreatment Plantaccommodating the wastewater demandscoming from Ayala Southvale Village located in Bacoor City, Cavite. The STP-1 (Alabang Area)is located along Mabini Street and STP-2 (Bacoor Area) is situated in St, Jude Street, TheseSTPs were constructed in 2000. In August of 2009, its operations were turned-over by AyalaWaterworks to Maynilad Water Services Inc.

Each STP has a design capacity of 31.25 cubic meters per day with an area of 40 sq.m(Alabang area) and 70 sq.m (Bacoor area). These facilities used the dipped-membraneactivated sludge process in treating wastewater before discharging it to Zapote River. Thesetreatment facilities are already disintegrated and not functioning to its purpose. Themembrane is already defective as well as the pumps, blowers and piping and control system.The biological tanks can still be utilized.

The proposal is to rehabilitate 5TP-2 [Bacoor Area) using the sametechnology, or to use cost-effective technology that will fit in the available area, STP-1 will be converted into pumpingstation (PS-l) that will pump out wastewater of the catered area of STP-1 and later run to the

proposed sewerline along Rizal St. from PS-l to STP-2.The project isexpected to improve theair quality since present facility has not been desludged and sludge have been undergoingdecomposition and emits obnoxious gases. Similarly, the structure has not been repaired andmay be suffering from structural defects and leaks.

There will be a marked improvement in the water quality since the wastewater treatmentfacility is already not functioning and it will be rehabilitated and will undergo biologicaltreatment and disinfection. The effluent quality will be monitored regufarly to ensure that itmeets Class C effluent standards as prescribed by the DENR. Receiving bodies wilt also beobserved and monitored to determine the effect of the STP to the water quality ofthe bodiesofwater. Implementation of the project will ultimately enhance the water quality of ZapoteRiver and ultimately the Manila Bay.

1,2 Description of Project Operations

1.2.1 Existing Technology (Dipped-Membrane Activated Sludge)

The two (2) STP's use the dipped-membrane activated sludge technology.

Activated sludge is a floe coagulated with aerobic microorganisms that has biochemicalactivities for treatment of organic wastewater. Bacteria are the most importantmicroorganisms in the activated sludge and responsible for the decomposition of the organicmaterial in the influent.

The sewage treated in the aeration tank is low in BOD but contains activated sludge andsome suspended solids. Dipped micro-filter modules are installed inside the aeration tank tofilter out these solids and obtain treated water low in suspended solids and BOD,

Figure 1. Process Flow for Dipped Membrane Activated Sludge

The Existing technology of the plant caters a capacity of 31,25 cmd per STP. Based on theprojection of the billed volume for Ayala Southvale, the existing capacity is less thanprojected capacity of the plant once the village will be fully occupied. (See table below). Thecurrent technology might be subjected to change based on the technology/process that canaccommodate the wastewater demand with the available land area.
