FOREWORD

Pithampur is one of the major Industrial towns of state of Madhya Pradesh. It is located

on Latitude 23° 25’ North and Longitude 77° 35’ East, Pithampur is a town and a

Municipality in Dhar district. . The municipal area of the town is 81.53 Sq.km. It is also a

renowned Industrial Estate and a suburb of Indore – being at a distance of 22 KM from

Indore. The town is having water supply based on Sanjay Jalayshay. Municipal Council

Pithampur is augmented the existing water supply for capacity upto 38.15 MLD to fulfil

the requirement for the year 2047 @ 135 lpcd.

At present there are 1 number of Water treatment Plants of capacity 10.39 MLD and 4

nos. of useful OHTs with a cumulative capacity of 2930 KL are constructed in different

parts of the Municipal area. Distribution system of length 62799.00 m and diameter 110-

355mm comprising of HDPE PN 6/DI K-7 above 350 mm diameter is being laid under

ongoing UIDSSMT.

The water supply being made by the Municipal Council is being analyzed for

identification and auditing of losses in the operation and maintenance of water supply.

The audit is being carried out primarily on following account,

a) Losses in the Production and supply of water upto Storage reservoirs

b) Losses in the storage and distribution of water upto consumer end

c) Losses in the revenue of water supply

d) Losses due to non-operation of electromechanical installation at desired efficiency

resulting in excess power expenditure.

The above parameters are being analyzed primarily to reduce the losses so as to keep

them within permissible limits. This is also important for improvement of service

deliverability alongwith financial health of ULB. In the light of water supply being

executed under AMRUT this is an excellent opportunity to identify and take

appropriate measures for the reduction in losses as described above.

As far as possible the data related to the operation and maintenance of existing water

supply system has been taken from the Municipal Council. Any discrepancy may be

brought immediately to the notice. Also the report is prepared for the approval and

necessary action by the ULB and Govt. of Madhya Pradesh.

1.0 INTRODUCTION OF PROJECT AREA:-

Pithampur is located on Latitude 230 25’ North and Longitude 770 35’ East,

Pithampur is a town and a Municipality in Dhar district. The municipal area of the

town is 81.53 Sq.km. It is also a renowned Industrial Estate and a suburb of Indore

– being at a distance of 22 KM from Indore via Rau and 8 KM from Mhow, which

is another well-known town. The town has developed as a notable industrial hub

of Madhya Pradesh and its proximity to Indore ensures use of the airport located

there, soon to become an international one. Pithampur enjoys good connectivity

(see Fig. 1.1) being located on a major road connecting NH 59 (Indore‐Ahmadabad)

and NH 3 (Mumbai‐Agra), as shown. Further, Pithampur can also access NH 79

towards the North‐West. Presently there is no rail connection.

Geography

Pithampur has got an average elevation of about 550 meters above MSL.

Pithampur has a typical sub-tropical climate. Three distinct seasons are

observed, summer, monsoon and winter. Summers start in mid-March and

can be extremely hot in April and May. The time temperatures can touch 45

°C on more than one occasion. Average Summer Temperature may go as

high as 42-44.c (100.4 °F) but humidity is very low.

Winters are moderate and usually dry. Lower temperatures can go as low as

5°C-6°C on some nights. Usually the temperature ranges between 10°C-

27°C during winters.

Raines are due to South west monsoons. The typical monsoon season starts

from June 15th and continues till Mid-September, contributing 32-35 inches

of annual rains. 95% of rains occur during monsoon season.

Demographics

As of 2001India census, Pithampur had a population of 68,080. Males

constitute 58% of the population and females 42%. Pithampur has an

average literacy rate of 62%, higher than the national average of 59.5%: male

literacy is 73%, and female literacy is 47%. In Pithampur, 18% of the

population is under 6 years of age.

like food processing, chemical processing, Distilleries, manufacturing,

textile industries.

Dhar district constitutes the reference district of this study. The district is part of

Indore Division ‐ one of the ten in the state. It falls towards the Western part of the

state and has an area of 8153 sq. km. The district has seven Tehsils, namely

DharBadnawar, Dharampuri, Sardarpur, Manawar, Kukshi and Gandhwani. Thus

Dhar town is important for being both the Tehsil and the District headquarter. The

district population is 1,740,577 (2001 census), showing a growth rate of 27.29%

(1991 – 2001).

Expected Urban Growth in the Region

Pithampur lies on the convergence of the State level and national level industrial

policies – which is expected to give way to rapid urban expansion in the region.

Delhi – Mumbai Industrial Corridor (DMIC) DMIC aims to be a Model Industrial

Corridor on international standards emphasizing a manufacturing and service base

and creating a global hub. Dhar‐Pithampur‐Mhow are identified for Investment

Region 6 (See Fig. 1.5 and 1.6). Zone 6 is also one of the six nodes which have been

taken up for implementation in Phase I during 2008 – 2012. Among others, it offers

to provide rail connectivity, captive power generation plants, environmental

protection and dovetailed residential, commercial, institutional infrastructure to

ensure attractive investment climate.

Population Density

The town comprises 31 wards within its administrative boundary. A ward‐wise

comparison of population densities was done to understand the density variation

in the town.

Figures showed that the overall town density is 7.55 PPH.

2.0 Existing water supply scenario:-

Pithampur has got its identity due to industrial area developed by MP‐AKVN.

Before 1995 it was in the control of Special Area Development Authority (SADA)

and the water supply system was controlled by Pithampur Jal Praday Priyojana

Project under State PHE department. Later the water supply system was handed

over to AKVN. After the Nagar Palika was constituted in 1997‐98, the water

supply came from ground water source (wells and tube wells). Since this supply

is insufficient, the AKVN supplements it.Main source for surface water supply is

Sanjay Jalashay Dam (situated in Ward 8) and Tubewells.

Presently the water is being supplied in the Municipal Area by Sanjay Jalashay

Dam and Tubwells. The total installed capacity of the water supply system is

approximately 14.82 MLD from Sanjay Jalashay and 1.50 MLD from tube wells.

(I) EXISTING OHTs:-

Housing Colony 350KL

Housing Colony 350KL

Pithampur 100KL

Akoliya 50KL

Mandlabda 50KL

Sagour 50KL

Among above find only one OHT at Housing colony of 350 KL tank is considered.

(J) DISTRIBUTION:

4.0 Proposed Project

As per the proposed augmentation project, it is proposed to augment the capacity

of existing Pithampur water supply so as to suit the drinking water needs of the

probable population of Pithampur for next 30 years taking net supply rate as 135

lpcd. The population of Pithampur for next 30 years (upto 2047) i.e., taking 2 year as

execution period and 30 years as service period has been estimated as 239900 i,e.,

design population. Taking 135 lpcd as per capita demand, the net water requirement

shall be 32.39 MLD. After accounting for 15% Transmission and Treatment losses, the

raw water required shall be 38.15 MLD. Presently, the town is getting water from

Sanjay Jalayshay @ 70 lpcd. The total water availability of water from this source is 14.82

MLD. The live storage of the dam is not sufficient to fulfill the water demand of the town

@ 135 lpcd. So this scheme is proposed to augment the storage and other components of

5.0 Water Auditing

The audit is being carried out in 3 parts namely,

a) Water Supply :

a. Losses in the Production and supply of water upto Storage reservoirs: The

present water production from all the sources is 14.82 MLD. This water is

being conveyed upto water treatment plant via raw water pumping main.

After Treatment the water is being pumped to various OHTs in the town via

Clear water feeder mains comprising of 250 mm – 500 mm 21280 m DI K-7

pipe. The pipe is in good condition and no leakages are being reported during

operation and maintenance of water supply. The storage capacity of 4 nos.

OHTs is 2930 KL. The water is supplied via filling of OHTs. There is no

measuring device in water supply system. The losses are being tabulated in

Table 1 which are approximately 30%.

Mitigation Measures in AMRUT

In order reduce the losses upto 15% for the treatment and transmission of

water it is proposed under AMRUT,

i. To provide Bulk Flow meters in the Rising and Feeder mains at the in-

flow and out- flow of Intake well, Water treatment plant and OHTs to

measure the flow of water.

ii. To provide PLC SCADA for monitoring the Flow and pressure of

water from Intake upto start of DMAs so as to immediately identify

any leakages in the system and making good the same as soon as

possible.

b. Losses in the distribution of water from OHTs upto consumer end: There is

no metering at the consumer end. The insufficient water availability along

with coverage of piped water supply system results in non-equitable water

supply with inadequate pressure. In order reduce the losses of Non-Revenue

Water (NRW) upto 15% in the distribution of water it is proposed under

AMRUT,

i. To augment the capacity of water supply system upto 38.15 MLD by

drawing 23.35 MLD from Narmada River (most sustainable source in

project vicinity) so as to supply water @ 135 lpcd to the present and

future population. Apart from the existing 69799 m distribution

network which is laid recently, it is proposed to provide piped water

supply to 100% of the Municipal area by providing and laying of 110

mm to 355 mm HDPE, PE 100 PN 6 & 350 mm DI K-7 class pipe

Page 13: REPORT FOR AUDIT OF WATER SUPPLY SYSTEM OF PITHAMPUR …nppithampur.org/wp-content/uploads/2018/04/14_wateraudit.pdf · 2018-04-22 · Pithampur water supply project Municipal Council,

Pithampur water supply project Municipal Council, Pithampur

Vatushilpi Project & consultants (P) Ltd. Dec, 2015

having total length of 79035 meters for distribution of water. The

proposed strengthening of network is being designed for equitable

water distribution @ 135 lpcd on minimum residual head of 7 m at 24 x

7 basis.

ii. Provide water connections to each households. The town is having

total number of households 23000 out of which 7402 nos.

households are already having water connections. 15598 nos. are

proposed in this scheme.Municipal Council intend to reduce the

number of Public Stand Post to the minimum (10-15) which shall also

me metered.

iii. In order to have accurate information of water supplied to the

domestic water meters AMR compatible shall be installed in all 20146

house service connections.

b) Losses in the revenue of water supply

Presently, there is no metering at the consumer end. The water is being supplied and

billed to the consumer on approximation and lumpsum basis. Water is being supplied

twice in a day, 1 hour each. However, there is no accurate information available on

account of quantity of water supplied. The quantity of water supplied has been

assessed @ 750 litres per connection of ½ inches for one hour.

The poor water supply distribution, inadequate information of quantity of water

supplied and unavailability of dedicated man-power results in poor efficiency of

revenue realization on account of water supply.

Mitigation Measures in AMRUT

Under AMRUT Municipal Council, Pithampur proposes,

i. To install AMR compatible domestic water meters in all the water connections.

The water tariff shall be as per the production cost of water. The production

cost of water at the time of commissioning of water supply system after the

works under AMRUT are completed is being wore out as Rs 8.60/KLL and

accordingly Domestic rate of Rs 8.33/KLL and Non- Domestic rate of Rs

13.34/KLL is being proposed to be levied.

ii. The operation and maintenance of water supply shall be done on contractual

basis which will facilitate the Municipal Council to have dedicated staff for

printing and delivering the Bills.

iii. The Smart Metering shall help in collection /realization of bills by sending
