Sewer collection systems move wastewater from homes and businesses to the wastewater treatment plant. Wastewater comes from activities like washing dishes, taking a shower, running the washing machine, and of course, flushing the toilet. It it goes down a drain it enters the collection system.
A sewer lateral connects the drains from homes and businesses on private property to the collection system. The property owner is responsible for the maintenance of the sewer lateral, including clogs and overflows.
Pump stations are used to get the wastewater to the wastewater treatment plant by pumping it up to a higher level until gravity can help it along. The wastewater treatment plant treats the wastewater and returns the cleaned water to the Kansas River.
