Wastewater collection system
Everyday, homes and businesses generate wastewater from sinks, tubs, toilets and industrial processing. The wastewater collection system, or sewer system, carries that wastewater from our customers to the wastewater reclamation facility.
Four-inch lateral pipes, which belong to the homeowner, carry the wastewater from your property to the sewer main. In a residential area, most sewer main under the street is 8″ in diameter. The 8″ pipe feeds into increasingly larger mains until it joins the giant 54″ mains which come into the treatment plant. This network of pipes is 700 miles long—long enough to reach New York City if laid end-to-end.
BCWS has an aggressive preventive maintenance program to minimize sewer overflows and keep the wastewater flowing to the treatment plant. We inspect and clean about one-fourth of our system every year.
We use two Vactor trucks that combine a pressure washer and a high-powered vacuum to clean the sewer system. Two additional trucks equipped with closed-circuit television and video recording equipment allow us to inspect the inside of the sewer pipes. A camera specifically built to fit inside the pipes sends a signal to the computer mounted inside the truck. A trained crew member controls the camera and watches the image on a high-tech computer monitor.
We use closed-circuit TV inspection to:
- Pinpoint the location of a sewer line blockage
- Find areas that need to be cleaned to prevent a blockage or back-up
- Identify pipe that needs to be replaced or repaired
- Inspect new pipe to make sure it is installed properly and according to specification
- Find illegal or improper sewer connections
- Inspect about 110 miles of sewer every year.
