Abstract
Abstract A monitor for an effluent disposal system for preventing suspended solids in an effluent from clogging a disposal field. A separate monitor housing having an inlet and an outlet is installed in the piping interconnecting a septic tank to a disposal field. A screening system in the housing screens out suspended solids. As the solids accumulate on the screening system over a period of time, the fluid level raises, actuating a float operated switch connected to means to signal that the system needs servicing. An additional float operated switch can be provided for indicating saturation of the disposal field.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
140 words
In an effluent disposal system including an upstream septic tank, a downstream effluent disposal field, and piping interconnecting the septic tank to the disposal field, a septic monitor interposed in the interconnecting piping for monitoring suspended solids in the effluent passing through the interconnecting piping comprising, a housing having an inlet and an outlet for coupling to the interconnecting piping, screening means mounted in said housing for continuously intercepting effluent flow therethrough, with suspended solids in the effluent being continuously collected on the upstream side of said screening means, said screening means being removable for periodic servicing, and automatic indicating means automatically responsive to an increased effluent level in said housing upstream of said screening means caused by a predetermined accumulation of suspended solids on said screening means to automatically provide an indication that the effluent disposal system requires servicing.
Claim 2
Dependent Claim
140 words
In an effluent disposal system including an upstream septic tank, a downstream effluent disposal field, and piping interconnecting the septic tank to the disposal field, a septic monitor interposed in the interconnecting piping for monitoring suspended solids in the effluent passing through the interconnecting piping comprising, a housing having an inlet and an outlet for coupling to the interconnecting piping, screening means mounted in said housing for continuously intercepting effluent flow therethrough, with suspended solids in the effluent being continuously collected on the upstream side of said screening means, said screening means being removable for periodic servicing, and automatic indicating means automatically responsive to an increased effluent level in said housing upstream of said screening means caused by a predetermined accumulation of suspended solids on said screening means to automatically provide an indication that the effluent disposal system requires servicing.
Claim 3
Dependent Claim
50 words
A septic monitor in accordance with claim 1 in which said automatic indicating means comprises float operated signaling means adjacent said screening means upstream thereof and responsive to an increased level of effluent in said housing due to collection of suspended solids on said screening means, to provide the indication.
Claim 4
Dependent Claim
43 words
A septic monitor in accordance with claim 1 in which said housing is buried in the ground and includes a portion thereof extending adjacent the surface of the ground for facilitating periodic access to said housing for periodic servicing of said screening means.
Claim 5
Dependent Claim
44 words
A septic monitor in accordance with claim 3 in which said housing is comprised of a selectable number of vertically interlocking sections, for facilitating providing a housing portion adjacent the ground surface for any particular depth of the interconnecting piping beneath the ground surface.
Claim 6
Dependent Claim
55 words
A septic monitor in accordance with claim 2 including additional float operated signaling means downstream of said screening means adjacent said outlet of said housing, for providing an additional signal in response to a predetermined effluent depth on the downstream side of said screening means as an indication of saturation of the effluent disposal field.
