Under an early commitment, the World Bank will finance the feasibility study, Suryanto, the head of the regional development planning board, said here on Monday.
Based on the result of the feasibility study detailed engineered design would be prepared and the budget of the project could be calculated, Suryanto said.
The World Bank has not talked about the fund aid as implementation is yet to be decided, Tri Hardiyanto, the project leader, said
The World Bank is to involve donor countries or related international financing agencies such as the United Nations Development Program (UNDP) in financing the project implementation.
The feasibility study will be held in the village of Atas Air in the lower district of Margasari in West Balikpapan, in the Somber Small Industrial Estate (KIK) Somber in North Balikpapan, and the Sepinggan housing complex in East Balikpapan.
The selection of the locations is based on the Balikpapan city development master plan.
Tri Hardiyanto said the feasibility study is to be completed in six months.
The World Bank provided the assistance on recommendation from the public works ministry, Suryanto said.
Other cities recommended by the ministry included Makassar and Palembang.
Gazali Rakhman, the spokesman of the Balikpapan drinking water supply company said the waste water after being processed could be used for various purpose but not for human consumption.
