Concrete Mix Factories in Ulaanbaatar are Recycling Greywater for Further Use to Reduce Their Water Consumption
Ulaanbaatar will reportedly face a drinking water shortage by 2020, according to water authority experts, as there is no alternative water source than groundwater. To prevent the problem and limit the use of drinking water, several concrete mix factories have established greywater recycling plants and started using the recycled wastewater for washing their mixer trucks, which consumed tons of fresh drinking water before.
Greywater to make up 60 to 70 percent of daily water use
One of the four factories is Premium Concrete LLC, which operates in the 20th khoroo of Bayangol District. The company previously used four tons of drinking water for its operation. Specifically, 600 to 800 liters of water is used for washing one mixer truck. Some mixer trucks are required to be washed five times a day, depending on the company's load.
Company officials report that they are saving 70 to 80 percent of drinking water previously used by using recycled greywater for multiple purposes.
The recycled water is used for not only washing, but also for watering the factory facilities to reduce dust.
