Septic tank alarm system
First Claim
1. In combination with a treatment tank, having a top in close proximity to ground level for collecting wastewater containing a quantity of solids from a structure, where suspended sludge is separated by gravitational settlement from an overlying liquid,a two stage sludge level alarm system to detect rising levels of said suspended sludge within said treatment tank, said system comprising:
- a.) a cylindrical housing extending through said top in interior communication with said overlying liquid and suspended sludge;
i.) upper and lower openings in a sidewall of said cylindrical housing;
ii.) weight sensitive switches disposed within said cylindrical housing below said openings, where said switches are rendered operative by the weight of sludge passing through said openings into contact with said switches; and
b.) an electronic alarm within said structure in electrical communication with said switches, where said electric alarm is activated when at least one of said switches is rendered operative.

Abstract
A two stage alarm system for detecting rising levels of sludge in septic tanks, and similar sedimentary tanks. The system, to detect a first or “caution” level, and a second or “critical” level of sludge, relies upon a pair of vertically positioned weight sensitive switching mechanisms which, when triggered by the rising levels of sludge, will send appropriate signals to a remote alarm mechanism, such as at the residence, to activate a “yellow” and/or “red” light, for example, thus alerting the owner of the tank to the need for remedial action.
