Wastewater Recycling Activity will support the construction of a Wastewater 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 (CHPPs)

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

Upon completion, the project is expected to satisfy up to 85% of the technical water needs of the combined heat and power plants using recycled water, thereby reducing the annual consumption of groundwater by up to 18 million cubic meters.
