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 (schedule of rates 2007-08 + 10% price escalation). The installation cost of the water supply improvement scheme is Rs.1199.12 lakhs. The Annual Maintenance cost is Rs.49.00 lakhs. 5.1.2 SEWERAGE i) Existing Status The town does not have an Under Ground Sewerage System. Disposal of the sewage is normally by way of individual facilities and the sullage is through the open drains. The main mode of individual disposal in the town is through septic tanks, low cost sanitation units and through public / community toilets. ii) Demand Assessment In order to improve the sanitation in the town, Under Ground Sewerage System is necessary with treatment facilities at terminal points. iii) Proposals The field survey for UGSS has been done by TWAD Board. Identification STP site is in progress. The total estimated cost of the proposed Under Ground Sewerage System for Vellakoil municipality is Rs.3300.00 lakhs. The Operation and Maintenance cost will be is Rs. 82.00 lakhs. 5.1.3 STORM WATER DRAINS i) Existing Status Vellakoil municipality has provided open storm water drains for a length of 19 km. The total length of the existing road length in the town is about 174.50 km. The percentage coverage of storm water drains is about 11%. 21
City Development Plan for Vellakoil Municipality SMEC India Pvt Ltd Final Report TNUDP III At present, storm water drains carry the sullage and rain water which is ultimately let into the PAP channel (Parampikulam Aazhiyar Program) and Kurukampalayam Pirivu (proposed STP site) without any treatment. This imposes health and environmental hazard to the natural water system and needs to be addressed through a proper treatment and disposal facilities. ii) Issues The main issues persisting in the town due to the absence of a storm water drainage system are summarized as follows:- • Open drains creating unhygienic conditions • Absence of Under Ground Drainage System in the town • Water stagnation in low lying areas during rainy season iii) Demand Assessment The residential areas of the town are provided with open drains. The town area is 64.75 sq.km and about 75% of land are undeveloped, agricultural lands or barren lands. The storm water is carried by the natural drain network in these areas emptying into the channels. Absence of UGSS and storm water drains in the residential areas of the town are the major causes of land and water pollution. This situation degrades the environment by emanation of foul smell and unhealthy conditions due to stagnation at a number of points. iv) Proposals Proposals by consultants To develop a Comprehensive Drainage Master Plan channelizing the runoff along the natural contours so as to cover the entire town and implement in phases. Measures to be taken to improve, upgrade and clean the existing natural and man made storm water drains to the required functional level with the involvement of local community to ensure sustainable operation Provision of new drains in newly developing areas Table 5.4 Storm water Drains - proposals S.No Description Capital Investment in lakhs 1 Preparation of Comprehensive Drainage Master Plan 3.00 2 Provision of new drains including newly developing area (15 km) 240.00 3 Rejuvenation of entire existing drain network (19 km) 57.00 Total 300.00 Annual O & M 4.50 Source: Analysis and discussions with municipal officials Therefore, the total investment required for the improvement of storm water drains (short term) is Rs.300.00 lakhs. The rest of the road length will be covered in the long term plan. 5.1.4 IMPROVEMENT TO WATER BODIES i) Existing Status There is no water body in the town maintained by the municipality.
