Water Transmission Line

Water Transmission Line from WTP to Heerassagala Junction and along Heerassagala Road

Description

The SCDP has given priority to reconstruct and rehabilitate the water supply schemes of the KMC area, and to expand and increase the existing capacities of the schemes operated and maintained by the KMC at present. In order to achieve the above objective, the project(SCDP) proposes laying a transmission line from Water Treatment Plant (WTP) located in Gatambe ,to Heerassagala junction through the railway crossing and to link this line to reservoir tanks to be constructed in the lower division of the Heerassagala Gramaniladari Division,(GND) along the Heerassagala Road. Another transmission line will be laid from the Heerassagala lower division reservoir to the reservoir tank to be built under the project in the middle division of the Heerassagala GND. In the meantime,a distribution line will be laid parallel to the transmission line from the Heerassagala Middle and lower reservoir tanks to the Heerassagala Junction along the Heerassagala road.


Water Treatment Plant (WTP) at Gatambe is the KMC’s main water purification unit situated 200 m from Gatembe junction along the left side of the Sirimavo Bandaranayake Mawatha. This has been established in 1956 and has been undergone rehabilitation from time to time. The present capacity of the WTP is 35,000 cubic meters. The half an acre land on which the WTP is built belongs to the KMC. Heerassagala lower division is situated 220 m from the second lane of the Heerassagala road at 561 M msl. Heerassagala middle is situated 150 m along the third lane of the Heerassala road 613 M. The length of the transmission line from WTP to Heerassagala junction is 1260 m and the length from the Heerassagala junction to reservoir tanks is 1444 m. The proposed development project consists of two components i.e. laying a transmission line from Water Treatment Plant at Gatambe to Heerassagala Junction through the railway crossing and then continuing the transmission line to Heerassagala lower reservoir first and from there to Heerassagala middle reservoir. Furthermore, a distribution line will be laid parallel to transmission line from the two reservoirs up to the Heerassagala Junction. Transmission line from WTP to Heerassagala junction is planned to lay beneath the walking passage on the right side of the road. From Heerassagala Junction to reservoirs along the Heerassagala Road, both transmission and distribution lines are planned to be laid along the road.
