An engineer, H. Thomas Jarrett of Glens Falls, NY, worked with me to design a suitable system that meets the requirements of the town, does not use too much land area, satisfies all environmental concerns, and runs on gravity except for one pump tank. The New Design Building codes have become tighter in recent years because of modern concern about the environment. The town granted a variance because the design meets its intended purpose and protects the environment much better than our previous system. The system was placed in service June, 1995. Any system this complex has many possible failure modes.
Ground water can leak into the system.
Pumps can fail. Power outages can occur. Float switches can stick open or closed. The overflow tank can fill. Pipes can clog.
