WICHITA (AP) — Treated sewer water might be part of the city of Wichita’s efforts to improve its water supply for the future.

City officials said this week they are examining several methods to use treated wastewater for everything from drinking to irrigation.

The Wichita Eagle reported that is one option that could be used as the city searches for a water supply for the next 50 years. A report from city public works officials and outside consultants on the future of the city’s water supply is expected this spring.

Public Works Director Alan King says the Kansas Department of Health and Environment is working on regulations for turning wastewater into drinking water, similar to regulations used in California.

But King and other city officials stress no final decisions have been made.
