scarcity, it may even be used as a source of drinking water
as it is completely devoid of any physical, chemical or
biological contaminants. The TDS level is less than 70
mg/L which is much less than that of conventional tap
water which is around 250 mg/L.
LESSON LEARNED:
Chennai along with its adjoining districts is one of the
most rapidly urbanising areas of the country and does not

changer in Chennai's water supply, given that it is among
the most cost-effective with nil environmental impact and

Ttown of the revenue division and taluk. The proposed location is near the central junction where passengers
are waiting on the road itself for long route buses having no waiting shed to depend upon. Moreover, it is home to
16+ hospitals and it is popularly known as “Hospital City” and has an approximate floating population of 20000
per day. The land under the ownership of the Municipality is used for construction of the project. The building also
has 12 number of taxi parking spaces in the ground floor. The total cost of the project is Rs. 94.75 lakh which is
raised by the Municipality. The Municipality planned to meet this expenditure from its own funds and HUDCO
grant. The design of the facility was carried out by engaging private consultants and the construction supervision
and quality assurance has been undertaken by the LSG Engineering Department. The operations & maintenance
part also is being taken care of by the LSG Engineering Department. The project offers many societal benefits in a
cost-effective manner.
