Residential Onsite Wastewater Treatment

A properly designed, installed, and maintained lagoon is an approved method of wastewater treatment for a private residence in areas where public wastewater treatment systems are not available. A lagoon is a good alternative for wastewater treatment and disposal where soil has high clay content with poor drainage, and the lot is at least three acres in size, and where a septic tank/effluent system is not feasible due to soil percolation rates. A lagoon can be installed in any type of soil provided a liner is installed that will not allow more than 1/8 inch of seepage per day. For any lagoon system, there must be at least two feet of vertical distance between the bottom of the lagoon and groundwater or fractured bedrock. A properly designed, constructed, and maintained lagoon will treat wastewater and protect the environment and human health; and can be inconspicuous or even pleasing in appearance.
