KRUENG MOUNTALA WATER SUPPLY FEASIBILITY STUDY
The concept to supply drinking water from Krueng Mountala to Seulimeum and onwards to Banda Aceh is technical feasible.
Costs for Intake, pre-treatment, transmission lines and reservoirs are estimated at US$ 18,566,000 and the costs of Supply network and service connections amount to US$ 23,520,000.
The proposed scheme would solve the current problems with water treatment in Banda Aceh (high turbidity of raw water, risk of up-stream contamination incidents, high costs for Operation & Maintenance).
The gravity fed system would require comparably lower operation and maintenance inputs (Electricity and chemicals).
The estimated investment costs of some US$ 13 million for intake, pre-treatment and transmission line for the Banda Aceh area are in the same order of re-investments in the Lambaro WTP of Kota Banda Aceh, due in 10 years time.
Furthering this concept could include:
At the water source
Collection and analysis water quality samples over a period of time, including analysis of trace metals, pesticides, major cations and anions, and nutrients - PO4-P, nitrate- N, nitrite-N, and ammonium;
Monitoring of water flow over a period of time, of particular interest will be the dry season base flow;
Proposal for source protection;
Evaluation of appropriate treatment process for raw water.
With respect to the transmission line
Field verification of technical feasible alignments, in particular old railway alignment and irrigation channel.
Concerning the service areas
Inspection of all existing facilities in Kota Jantho and Seulimeum with PDAM operators;
Mapping and analysis of existing networks in Kota Jantho and Seulimeum with the help of knowledgeable PDAM operators, e.g. using EPANET;
Compilation of information on ongoing and planned housing schemes in the area, the ‘airport city’ and the port-area development, realistic and robust demand forecasts;
Study of technical feasible service area as well as build-up over time using high resolution aerial imagery. The imagery can be obtained from the GTZ / SLGSR GIS- centre in Jantho. Contact person at the GIS centre is Jochen Kranik at firstname.lastname@example.org.
