IDC was the local counterpart consultant to VINCI Construction GrandsProjects S.A.S, France, the main consultant, for the design of Kantale Water Treatment Plantof the GreaterTrincomalee Integrated Water Supply Project, funded by the Government of France. Consultancy includedpreliminary process design (including the sizing of structures,preparation of necessary drawings, topographic surveys& leveling,soil investigations, treatment plant hydraulic profile, process&instrumentation diagrams) detailed design (including civil designs, process and equipment designs and power and automation design, structural designs) and detailed drawings (isometric piping drawings,RC drawings, formwork drawings, general arrangements and detailed drawings). Design works also included drainage system,roadwork, buffer tank, clarifies, filter, treated water tank, wastewater tank, sulfuric acid tank, trenches.
IDC was the local counterpart consultant for the project. The expected outcome of the project was to enhance the distribution system and reduce Non- Revenue Water (NRW) in Greater Colombo Water Supply System through upgrading the water distribution system and establishing an appropriate mechanism.
The Consultancy service included, feasibility studyfor the proposed ADB investment in National Water Supply Drainage Board, Sri Lanka for the reduction of NRW, proposal & justification for upgrading, rehabilitation and reinforcement of primary and secondary distribution mains and replacement of connection pipes in old district zones, introduce NRW zone distribution network practice, recommendation for necessary equipment, establishing NRW section with operating teams to attend leaks and repair, assist NWSDB to enhance it’s institutional, operational and implementation capacity to address NRW issue.
Positive economic multiplier effects of lowered NRW levels on tariff rates, consumption, productivity and public hygiene also were studied. Implications of low NRW and how it reflects inhigher customer satisfaction, O&M efficiency, and patronage that fuel the utilitywere also part of the study.
Consultancy service included several aspects of the rehabilitation of Galle urban water supply project, feasibility of major rehabilitation for the benefit of 75,000 inhabitants. Detailed designs of the replacement of main transmission main comprised of computer based theoretical modeling of transmission network and field simulations, designs of 8km long transmission line of 500 mm PE and preparation of drawings. The National Water Supply and Drainage Board, was assisted in tender process including preparation of tender documents and tender evaluation etc. IDC also carried out the project management and construction supervision and quality assurance. The project was funded by the American Red Cross Society.
IDC provided consultancy services for the implementation of Eastern Province Water Supply development Project (Rural Component), which was the first ever decentralized RWSS project in Sri Lanka implemented in Trincomalee, Batticoloa and Ampara districts. The work involved water source investigations, conceptual and preliminary designs, detailed designs of water supply schemes, preparation of drawings and BOQs. Consultancy services also included formulation of a suitable and appropriate Operation& Maintenance (O&M) models for each sub project, capacity building of Provincial Council and Local Authorities through transferring of technical skills, tariff setting, tender procedures, contract management ,construction supervision and quality assurance. The project was funded by Japan International Cooperation Agency (JICA), Japan.
IDC was the design consultant for GS Engineering & Construction Corp, Korea for their bid preparation for Ruhunupura Water Supply Scheme, Sri Lanka. The design scope included re-validation of water needs and forecasting future demands, carrying out conceptual, detailed and structural designs of intake, raw water transmission, distribution network, process design, water treatment and structural designs of treatment plant, civil &structural designs of storage tanks. The consultancy services also included preparation of mechanical, electrical and automations designs involving pumps and other equipment. preparation of detailed drawings, BOQs, specifications, technical guide for construction and O&M procedures for all the above components of the water system.
IDC was the consultant to carry out the above project. Consultancy services focused mainly on capacity building and institutional developmental Provincial Council (PC) and Local Authority (LA) levels for the implementation of RWS projects in Kandy, Nuwara Eliya and Matale districts of Central Province in Sri Lanka. Consultancy services included technical and financial capacity development support to LAs, transfer of technical knowledge to PC and LAs in designing of rural and small town water supply systems, construction supervision and quality assurance. Services also included providing advice to Community Based Organization (CBO) in implementation of rural sanitation progrmame through revolving fund mechanism, training of CBOs in all aspects of RWSS project implementation, Operation & Maintenance (O&M) and financial management.
IDC in association with COWI, Denmark and Ceywater Consultants, Sri Lanka carried out theassignment of preparation of the project implementation plan(PIP) of 2nd Community Water Supply and Sanitation Project (CWSSP) for approximately US$ 40 million, enabling the Government of Sri Lanka for timely negotiation with the World Bank. CWSSP was the first ever decentralized Rural Water Supply and Sanitation project implemented through Provincial Councils and PradeshiyaSabhas (LAs) and hence, series of guidelines, manuals and training modules were prepared in order to ensure the effective implementation of the project activities.
Plan, Sri Lanka is an international NGO active in Sri Lanka for over 40 years. IDC undertook an evaluation to assess the intervention of Plan, Sri Lanka in the communities. The evaluation covered the water supply, sanitation and hygiene education sector project implemented by Plan.
