Drought forces Texas city to treat, recycle wastewater for drinking

July 10, 2014 | General RCAP News

The city of Wichita Falls, Texas has begun an ambitious attempt to address the shortage of drinking water in the region caused by recent prolonged drought conditions. The project, which is the largest of its kind in the country, involves combining treated wastewater effluent and lake water for the public drinking water supply.

The Times Record News explains the process as:

taking a 50/50 blend of treated wastewater effluent from the River Road Wastewater Treatment Plant and pumping about 7.5 million gallons to the Cypress plant through a 12-mile pipeline. The water then goes through microfiltration and reverse osmosis to remove compounds from the water.

After the treated water is put in a holding lagoon, it is then mixed with lake water and sent to a conventional treatment clarifier before ending up in the storage tanks.

It takes about one day and 10 hours for the entire process to take place and the water is pushed out through the distribution system.
