Present water source of Altai city is not meeting the standards of the public potable water supply, the ratio of calcium and magnesium is improper and the amount of water resource is unable to meet present requirements. Thus it has adverse impact on human health. Though many survey and investigation projects for underground water were held over the past years have not found any resources meeting the water quality standard.
In order to resolve the question it was decided to pump water from the Taishir water reservoir by the coastal water intake structure and transmit it to Altai city through 52.8 km long underground pipeline. In order to solve the above mentioned issues, proposing to build coastal intake structure to filtrating water from the existing Taishir H ydro Power Station and transfer water to Altai city through underground pipeline.
Demands of the water points along the Altai city and pipeline alignment will be 47.8 l/sec or 1.26 million m3/year in the year 2030 and 70.8 l/sec or 1.86 million m3/year in the year 2040.
As the average flow of many years is 12.0 m3/sec, the total project consumption will be respectively 0.4 % and 0.59% of the flow, 0.3% and 0.44 % of the utilizable volume of Taishir hydro-power plant reservoir, 0.13% and 0.19% of the total volume of the reservoir which will not affect the amount of water in Taishir reservoir.
Also, the yearly evaporation from Taishir reservoir is 700 mm which is 20 to 30 times lesser than 36.4 million m3/year. This project is funded by the Austrian government grant.
