Description

A sub-project involving the rehabilitation and redesigning of the existing silt traps and the construction of additional silt traps with better facilities for de-silting has been identified. It is one among several major investments that will improve on the city’s major drainage infrastructures and flood control system, including upstream silt traps rehabilitation and construction.


Under this particular sub-project, the following activities have been prioritized:


• • Rehabilitation of 2 Nos. of existing sit traps (Lower Mahamaya, and Lower Red Culvert)

• • Construction of 3 Nos. of silt traps (Upper Red Culvert, Upper Hilllwood, and Upper Mahamaya)


The above structures are small in size and located in five different places that come within three GNDs: Ampitiya North, Ampitiya South and Malwatte GN Divisions.


The sub-project will directly benefit the city population totaling 108,000 including in particular the residents around the identified locations of silt traps totaling about 370 persons, and an estimated 350,000 commuters to the city including tourists. The district’s population of 1.37 MN would be among the indirect beneficiaries. The beneficiary population is multi-ethnic and multi-religious.
