Can they be used to clean up lakes or streams where one-time bungalow type second homes have become year-round residences?
JSA: Yes. This may be the most needed and promising use of aerobic systems. The small summer-only minimal-use sized traditional septic systems cannot handle the needs for year-round use. They often fail and leach pollutants into the lake or stream that promote growth of vegetation that often chokes the water and because of high bacteria levels make it unsafe to use for recreation. Aerobic systems can solve this problem, end the pollution flow into the lakes or stream, and make the environment safe again for recreation.
