Olathe wastewater achieves 100 percent compliance

Post Date:02/10/2020

In 2019, both Olathe wastewater treatment facilities achieved 100 percent compliance with all state and federal requirements.

Throughout the year, operations staff reported 5,247 data points to the Kansas Department of Health and Environment to reach compliance. This achievement marks 17 consecutive months of 100% compliance at Cedar Creek Wastewater Facility and 45 consecutive months at Harold Street Wastewater Facility.

Wastewater is “used” water. Water from the faucet, washing hands, running the garbage disposal, taking a shower, flushing the toilet, or running the dishwasher, becomes wastewater once it goes down the drain.

The City of Olathe is responsible for collecting, transporting and treating wastewater generated by homes, industry and businesses in Olathe. The City operates two wastewater treatment plants and treats over one billion gallons of wastewater every year. Millions of gallons of wastewater enter our treatment plants every day. It travels through various stages of treatment to remove waste and eliminate disease-causing bacteria, and in turn protecting the environment for human and aquatic life.
