Incorporation of a water level indicator in the design and construction of septic tanks.

Abstract

Septic tank blockages and overflows have always been a common problem. Mitigation of this problem would require an automatic sensing mechanism which would always help to alert people early in advance. This project was therefore intended to incorporate a water level indicator in these systems to curb the above problem. A circuit was designed and its sensors installed at different depths of the septic tank such that when the level of wastes rose and reached these present levels, different warning lights glowed and a buzzer sounded at the last level. This therefore, gave early warnings so that the manholes of the septic tank could not burst open to ooze out foul wastes which would disrupt normal activities of man. This project is geared towards improving hygiene in private homes, residential facilities and public places of convenience where septic tanks not connected to sewage lines are used.
