In most states, you must maintain a minimum distance from homes or public-use areas when building or expanding an aerobic or anaerobic lagoon, notes Jose Bicudo, assistant extension professor of biosystems and agricultural engineering at the University of Kentucky.
Keep the following considerations in mind when selecting a site for your lagoon:
- Situate the lagoon at least 400 feet from wells and waterways.
- Use landscaping, vegetative windbreaks or buildings to block public view of the lagoon.
- Locate lagoons on soils with low permeability.
- Contact your state’s regulatory agency to determine what sealing materials — plastic liners or a layer of compacted clay, for example — are required before you design and construct a lagoon.
- Position the bottom of the lagoon at least 2 feet above the highest ground water level.
