Abstract

A sewer cleaning vehicle is disclosed. In one aspect, the sewer cleaning vehicle has a refuse storage tank having a first end with an opening. The sewer cleaning vehicle may also have a recycled water storage tank and a packaged liquid reclamation system for cleaning and transferring water from the refuse tank to the recycled water storage tank. In one embodiment, a hinged cover having a first side and a second side is pivotally mounted to the storage tank. The hinged cover can be movable between a first position in which the hinged cover covers the storage tank opening and a second position in which the storage tank opening is uncovered by the hinged cover. A transfer pump and a separator are supported by the hinged cover and are in fluid communication with the refuse tank through a port in the hinged cover.

First claim

What is claimed is:

1. A sewer cleaning vehicle comprising:
(a) a refuse storage tank having a first end with an opening;
(b) a recycled water storage tank; and
(c) a packaged liquid reclamation system including:
i. a hinged cover having a first side and a second side and being pivotally mounted to the refuse storage tank, the hinged cover being movable between a first position in which the hinged cover covers the refuse storage tank opening and a second position in which the refuse storage tank opening is uncovered by the hinged cover;
ii. a transfer pump supported by the hinged cover on the first side, the transfer pump having an outlet and an inlet in fluid communication with the refuse storage tank via a first inlet port in the hinged cover; and
iii. a separator supported by the hinged cover on the first side, the separator having an inlet in fluid communication with the transfer pump outlet and a first outlet in fluid communication with the recycled water storage tank.

2. The sewer cleaning vehicle of claim 1 , further comprising a pre-screen assembly mounted to the hinged cover on the second side, the pre-screen assembly covering the inlet port on the hinged door.

3. The sewer cleaning vehicle of claim 1 , wherein the transfer pump is activated by a float switch located within the recycled water storage tank.

4. The sewer cleaning vehicle of claim 1 , wherein the separator has a second outlet in fluid communication with the refuse storage tank via a second inlet port in the hinged cover.

5. The sewer cleaning vehicle of claim 1 , wherein the recycled water storage tank includes an overflow valve assembly.

6. The sewer cleaning vehicle of claim 1 , further comprising a second pump in fluid communication with the recycled water storage tank, the second pump being for pumping recycled water to a hose reel from the recycled water tank.

7. The sewer cleaning vehicle of claim 6 , further comprising a fresh water storage system in fluid communication with the second pump.

8. The sewer cleaning vehicle of claim 1 , further comprising a first platform mounted to the hinged door, the first platform being for supporting at least one of the transfer pump and the separator.

9. The sewer cleaning vehicle of claim 8 , wherein the first platform is rotatably mounted to the vehicle.
