was implemented from 18.7.1996 by new schemes executed by
The details of the scheme on completion
is as detailed below.

with well Sorted river sand available was selected to provide
5 Nos. Of infilteration wells in Colleroon river.
2.Head works :-
The water from the above 5 wells is pumped by 5H.P submersible
Pump sets with duty of 715 lpm (2 sets for each well and one
set as stand by totally 10 Nos with 20 m head each ) to a
common sump cum pump room through 5 Nos of each independent
connection main laid in 100 mm CI D/F pipes for a total length
of 1014 mtrs.
3. Connecting main :-
100 mm CI pipe have been laid from infiltration wells to sump
as a connecting main in five parallel lines to a length of
about 1014 mtrs total length the pumbed water is being conveyed
from infiltration wells to sump cum pumb house. These pipes
are rigidly fixed below water level. main anchorage arrangement
along with cables using mild steel angles bold and nuts to
avoid dislocation on alignment of pipe line during flood and
to protect against scouring action.
4. Pumb Room
The common sump cum Pumb house is 8.00 m dia and the capacity
of the sump is 1.50 lakhs litres has constructed to collected
the water from infiltration well to collection sump is again
pumped to service reservoir constructed at Sirkazhi town by
means of 50 H.P Centrifugal pump with a discharge of 3558
lpm against 38 mts head which is installed at Pump House.
The controlling switches of submersible pumpsets 5 Nos are
also installed in the pump room.
5. Transmission main :
The transmission main is laid to meet the requirements of
ultimate population of 54900 in the year 2011 through which
the water being conveyed from sump cum pump house to service
reservoir by means of Centrifugal pump sets.
350 mm AC-CI-10 Pipes including 350 CI Pipes = From LS 0.00
m to 12567.05
300 mm AC-CI-10 Pipes including 350 CI Pipes = From LS 12567.05
(i.e) 350 mm AC CI-10 Pipes = 12460.20
350 mm CI pipes = 106.85
350 mm AC CI-10 Pipes = 2823.50 = 93.50
Total = 15283.70 + 200.35
Total = 15484.05 m
At present 6 Nos of 350 mm Sluice valves
, 5 Nos of 200 mm scour Valves , 9 Nos of double air valves
are provided along the alignment of transmission Main.
6. Service Reservoir:
Service reservoir of 12.00 lakhs litres capacity (12.00 m
staging height) at Sirkazhi has been constructed . The water
collected from Head works are distributed to the public of
