SEEPAGE SYSTEM
It is combination of two or more pumps installed atevery underground station to discharge theseepage water from Seepage Pit to MunicipalStorm Water.
Their operation based on the level sensors signalsinstalled in the seepage pits
Their Master/Slave operation decided on the basisof their run-hour recorded by the BMS
Some of the Seepage Pumps are also installed inbetween the tunnels to extract accumulated waterinside the tunnel (i.e. between NDI & RCK; RCK &
PCK; BRKR & MDHS etc.)

SEWAGE SYSTEM
These Pumps are installed at few stations (at thistime only at RCK)
They supply the soft water to the station service
tanks to fulfill the stations requirements
Other stations soft water requirements are fulfilled
by gravitational flow of soft water
