Wastewater Recycling Activity

Wastewater Recycling Activity will support the construction of a recycling plant to further treat some of the effluent from the city’s central wastewater treatment plant, along with pipelines, storage tanks, and control systems to deliver this recycled wastewater to the combined heating and power plants, the city’s largest consumers of water. The wastewater recycling plant, which is first of its kind in Mongolia, will make water reuse practice possible and reduce the demand for freshwater among Ulaanbaatar’s largest industrial facilities through reuse of the city’s wastewater.

The funding for this activity will finance the following three set of works, including:

1. Construction of a Wastewater Recycling Plant

2. Installation of pumping stations and associated pipelines to convey the recycled water to water storage facilities near combined heating and power plants (CHP)

3. Installation of internal piping, storage facilities, and control systems to facilitate the use of recycled wastewater for certain processes within CHP-3 and CHP-4 (modification)

CHPs in Ulaanbaatar use 21 million cubic meters of freshwater (50 000 cubic meter/day which is equal to 23.8 percent of total water use of the city) from groundwater resources a year (mainly for cooling) and 15 million cubic meters or 70 percent of which is used for cooling, cleaning, and ash removing.

Recycled wastewater will reduce the need for freshwater by up to 18.3 million cubic meter/ year (50 000 cubic meter/day), thereby making the freshwater available for household and industrial consumption. This first wastewater recycling plant of Mongolia will help to pave the path for efficient and responsible management of the scarce water resources of Ulaanbaatar.
