c. Mode of supply
There are some parts of the town where water is supplied through the Lorries for about 3 hrs in the
morning and 3 hrs in the evening totalling to 1.0 lakh litres per day. During summer season the
quantity of water supplied through Lorries increases. Water Supply by Lorries is not a sustainable
solution and it may lead to other problems including traffic congestion and accidents.
d. Frequency of supply
Water is supplied for 2 hrs every alternate day in Krishnagiri town. This exposes the entire population
to the hazards of unhygienic conditions, mosquito breeding near storage places and also the
substantial amount of water is thrown away every alternate day for refilling of fresh water.
4.4 Sewerage and Sanitation
4.4.1 Underground Drainage (UGD)
Current status
There is no dedicated UGD system for carrying sewage and storm water separately in the town. The
roadside drains are used for carrying both the sullage and rainwater. The main mode of individual
disposal in the town is through septic tanks, Low Cost Sanitation units and through public
conveniences.
Proposed UGD System
Exhibit 4.7 Details of public conveniences
Sr. No. Particulars Number
1 Septic tank (ST) 11413
2 Low cost sanitation units (LCS) 974
Total 12387
Total households (No.) 14885
% of total HH covered through ST & LCS 83%

Due to the percolation of sewage water into ground many households are shifting from LCS to septic
tank units. In order to overcome the problems, municipality has proposed to provide the sewerage
system and a plan was prepared by TWAD board at an estimated cost of Rs 24.69 crore. The
committee is reviewing the possibility new technology to be adopted for setting up of sewage
treatment plant (STP) which will reduce the land requirement for STP unit to 1-1.5 acre. According to
the municipality the decision regarding it will be taken soon. Exhibit 4.8 gives details of the proposed
UGD scheme for Krish-M.
