• Water supply and sanitation
Combined Water Supply Schemes (CWSS) are being implemented where more than one local body either
urban or rural with a common source of water supply is involved with financial assistance under the Minimum
Needs Program , National Rural Drinking Water Program and with funding from financial institutions like
TUFIDCO, TNUIFSL, NABARD and Asian Development Bank.
At present, water being supplied to the beneficiaries of Town Panchayats and Village Panchayat of this CWSS
through Bore wells, open wells and infiltration wells in River Pazhayar. The sources are mainly recharged by
irrigation channels during the flow period of nine months only. This is not sufficient throughout the year. Keeping
in view the severity of the problem for providing adequate safe drinking water perennial river Kothayar River is
proposed as source. It is proposed to draw the total net requirement of raw water from Kothayar River on the
upstream side of Thirparappu falls at Kaliyal.
It is proposed to tap the Raw water from River Kuzhithuraiyar near Chengilagam through 8 m dia meter intake
well. The water from the intake well will be pumped to the proposed 1 lakh litre Sump by 3 set of submersible
pumpset through 250 mm CI LA class pipes. The water from the sump will be pumped to the Treatment site at
Athencode by 3 sets of Centrifugal pumpset through 600 mm BWSC Pipe. After the full scale treatment the
water will be pumped to the various beneficiaries through existing system of pumping mains of 22420 m by
interlinking. It is also proposed to replace the existing pipe line for a length of 5415 m, for the 79 habitations in
Melpuram Union,and it is proposed to lay 80383 m of pumping main and branch pumping main.
The raw water will be abstracted through off take well from the river and will be pumped for about 23.28 KM
through 700m MS and 500 mm and 450mm DI Pipes to the proposed treatment unit of Capacity 19.15 MLD
at Arumanallur. From the Treatment Unit, the clear water will be conveyed to the proposed 39 Nos of sumps in
the Town Panchayats and Village Panchayats through 500mm to 200 mm DI Pipes and 160 mm to 50 mm PVC
Pipes for a distance about 162.16 KM.
From the sumps water will be pumped to the existing 287 numbers of existing service reservoirs and 4 nos of
proposed service reservoirs in the Town Panchayats and Village Panchayats for a length of 271 KM and water
