Background

The City of Bintuli is a thriving center of commerce and industry in the Republic of Kabastan. The main industries in the area include metal manufacturing, coal extraction, chemical manufacturing, construction, papermaking and food processing. The value of industrial output in 2015 is estimated at $200 million while agricultural output is valued at $16 million. In recent years, the quantities of industrial and domestic effluent discharged into the Nombeng and Weban Rivers, as well as other streams and small rivers in the area, have increased rapidly. According to the Environmental Protection Agency (EPA), total industrial and domestic effluent in the Bintuli is 163,700 m3 /day. Currently, (5 times X4) percent of this effluent is treated by an existing treatment system. The plant is running at its full capacity. All the untreated industrial effluent is currently discharged into the nearby rivers. The daily total industrial and domestic effluent is predicted to increase at an annual rate of (X3/10) percent. It is proposed to build a wastewater treatment facility and associated pumping stations and drainage pipework. The treated water of clean water standard will be discharged into the Nombeng River for use by industry and agriculture. Bintuli, like many cities in Kabastan, is facing serious depletion of groundwater resources and severe pollution of surface water due to insufficient infrastructure available to accommodate the rapidly increasing amounts of industrial and domestic effluent. Currently, the entire untreated domestic and industrial sewage of the city
