City Development Plan for Vellakoil Municipality SMEC India Pvt Ltd
Final Report TNUDP III
measures have been suggested. The water supply demand calculated by the TWAD Board for
the intermediate population (2024) is 6.1 MLD and Ultimate year (2039) is 7.32 MLD.
The town is experiencing high population growth as the town has a high potential for industrial
growth. Therefore, the total demand of water supply calculated for intermediate period is 8.31
MLD and ultimate period is 12.48 MLD.
The present storage capacity of the service reservoirs is of 13.5 Ll. Therefore the storage
requirement will be 12.48/3 = 4.16 MLD < 1.35 MLD (existing). Hence, additional storage of 1.42
ML is required for intermediate period and 2.81 ML, required for the ultimate period.
iv) Proposals
The source proposed for this project is River Cauvery near Kodumudi. The proposed head works
will be located just on the upstream of the existing headworks of Muthur-Kangeyam CWSS. It is
proposed to draw 6.11 MLD for the intermediate stage and 7.32 MLD for the ultimate stage for
Vellakoil alone.
The salient features of the proposal are the head works, pump sets, raw water pumping main,
treatment plant, clear water reservoir, clear water pump sets, pump house, Booster station,
Laying of distribution system (feeder mains only) for 23 km and Construction of 4 OHTs at
Melagoundanpalayam colony (1Ll), Muthur road (5Ll), Sivanathapuram (3 Ll) and Pudur road (2
Ll). The per capita cost for this project is Rs.2926.00 and the cost per 1000 liters is Rs.8.05
