Urban Water Projects

Climate Resilience Improvement Project (CRIP) under Ministry of Irrigation is developing Basin Investment Plans (BIP) for 10 selected river basins, as the Sri Lankan cities are becoming increasingly vulnerable to the impacts of natural disasters with climate change impacts. Out of the 10 river basins, Attanagalu Oya has a high priority for flood protection since it hosts a large population, and important social & economic infrastructure in Gampaha District, which is considered to be the fastest growing area in the country. Gampaha and Ja-Ela are major cities in Gampaha District and have been affected by flooding frequently and most recently in 2016 and 2018. With the mentioned impending developments in the study area, the applications of Flood mitigatory measures for Gampaha and J-Ela have become very important. LHI has carried out the feasibility study including following investigations; • Kickoff meeting, site inspection, stakeholder consultation, data collection & inception workshop • Hydrographic & topographic Survey,and geotechnical investigations • Review & analysis of previous studies and development / upgrade flood models • Development feasibility level designs and model application with proposed interventions • Economic analysis, and social & environmental assessment • Recommended feasibility solution • Feasibility report and workshop
