Claim 3
Dependent Claim
76 words
The system of claim 1 wherein said treatment and settling tank overflow inlet, said digester overflfow inlet, and said effluent storage tank overflow inlet are at substantially the same height so that overflow fluid backup from said overflow tank and wastewater holding tank will rise to the level of said treatment and settling tank, digester, and effluent tank inlets to thereafter flow into any one of said treatment and settling tank, digester, and effluent storage tank.
Claim 4
Dependent Claim
62 words
The system of claim 1, including means for selectively transferring fluid from said overflow tank to said holding tank down to a level considerably lower than the overflow tank outlet of said gravity overflow means, and including a level sensing alarm within said overflow tank for indicating a fluid level within said overflow tank above a predetermined level indicative of system failure.
Claim 5
Dependent Claim
23 words
The system of claim 3, wherein said alarm means includes means for automatically dialing a predetermined telephone number and transmitting a predetermined message.
Claim 6
Dependent Claim
15 words
The system of claim 1, including means for aerating material contained within said overflow tank.
Claim 7
Dependent Claim
38 words
The system of claim 5, including means for sensing the dissolved oxygen content within at least one of said tanks and controlling the aeration of at least said one tank in response to the sensed dissolved oxygen content.
Claim 8
Dependent Claim
38 words
The system of claim 1, including means for sensing the dissolved oxygen content within at least one of said tanks and controlling the aeration of at least said one tank in response to the sensed dissolved oxygen content.
