The Nelson Wastewater Treatment Facility (WWTF) is Johnson County Wastewater's (JCW) oldest treatment facility, dating back to the 1940s, and a significant portion of the facility is at or near the end of its useful service life. The existing collection system(s) for the Nelson WWTF are sized and constructed with materials and technologies that are now outdated, and as a result, the system experiences issues during wet weather events. In addition, the system contains four satellite peak excess flow treatment facilities (PEFTFs), which discharge directly to adjacent waterways during significant wet weather events after primary treatment and disinfection, which is not an ideal treatment solution. In 2018, JCW determined the optimum solution for a long-term capital improvement plan was to upgrade and/or modify the current off-site pump stations and build a new, state-of-the-art Nelson WWTF facility.
Installation of newer treatment technologies and addition of provisions for expanded future wet weather treatment will be the most cost-effective way to meet future EPA/KDHE discharge regulations and provide a long-term treatment solution for our customers. The treatment technology currently in place at the Nelson WWTF is not capable of meeting future water quality standards required by the Environmental Protection Agency (EPA) and the Kansas Department of Health and Environment (KDHE). When discharged in abundance, ammonia, nitrogen and phosphorus can be harmful to aquatic life and encourage the growth of nuisance algae in surface waters. The collection system that the Nelson WWTF serves is also aging and can experience issues during large rainfall events. Throughout the project duration, the facility will continue to treat all incoming wastewater flow.
