Abstract
An apparatus and method for improving the operation of sewer systems includes a first set of sewer lines connected to a source of other water and a second set of sewer lines of smaller diameter than the first sewer lines connected to sources of sanitary effluent, the first and second sets of lines being separately connected to a sewerage treatment plant. The second set of sewer lines can be attached to the interior surfaces of the first set of sewer lines by an adhesive material and fasteners. A liner can be provided in the first sewer lines with the second sewer lines being positioned between an exterior surface of the liner and the interior surface of second sewer lines.
Claims20
A combined sewer pipe apparatus for conveying sanitary effluent and storm water from sources to a treatment plant comprising:
- a larger diameter first sewer pipe adapted to carry storm water and having an interior surface;
- a smaller diameter second sewer pipe adapted to carry sanitary effluent and extending through said first sewer pipe;
- and
- a fastener means attaching said second sewer pipe to said interior surface of said first sewer pipe.
An apparatus for separating sanitary effluent from storm water in a sewer pipe comprising:
- a sanitary sewer pipe adapted to carry sanitary effluent and sized to extend inside an outer sewer pipe adapted to carry storm water and having an interior surface;
- and
- a fastener means for attaching said sanitary sewer pipe to the interior surface of the outer sewer pipe.
A combined sewer pipe apparatus for conveying sanitary effluent and storm water from sources to a treatment plant comprising:
- a larger diameter first sewer pipe adapted to carry storm water and having an interior surface;
- a smaller diameter second sewer pipe adapted to carry sanitary effluent and extending through said first sewer pipe adjacent said interior surface;
- and
- a fastener means attaching said second sewer pipe to said interior surface of said first sewer pipe, said fastener means including a plurality of fasteners spaced apart along a length of said second sewer pipe and engaging an exterior surface of said second sewer pipe and an adhesive material attaching said fasteners to said interior surface of said first sewer pipe.
The apparatus according to claim 19 including a liner extending through said first sewer pipe, said second sewer pipe being positioned between said interior surface of said first sewer pipe and an exterior surface of said liner.
