What is enhanced treatment?

An enhanced treatment unit is any private or semi-public waste water system which has been designed to improve the quality of waste water effluent by reducing total nitrogen and one or more of the following: biological oxygen demand, dissolved solids, suspended solids, phosphorus, or bacteria prior to disposal to the soil.


The sanitation code requires enhanced treatment units for lots less than 3 acres. These units also require yearly maintenance to be completed by the manufacturer representative or a licensed waste water installer. All units have an approval process prior to installation in Reno County. Below is information about enhanced treatment units and a list of licensed waste water contractors.
