Re: “Sewage project poses danger” (letter, 7-18).
We hope these answers ease concern regarding the Chambers Creek Tunnel Rehabilitation project. This project rehabilitates an existing sewer pipe that is nearly 30 years old and subject to failure.
We know the hazards of sewage transport and are serious about keeping control of it. We have taken several safety measures at the site. Traffic speeds through the construction zone are slow and monitored by flaggers. This minimizes the potential for a high-speed impact to the bypass pipe. Also, sewage won’t be in the bypass pipes when we are not on site monitoring conditions.
We are using high density polyethylene pipe for this temporary application because it is durable and flexible. Before it carries sewage, however, the pipe will be pressure tested with clean water to detect leaks and any other problems.
Once the bypass system is operational, we will continuously monitor the pumps for proper operational pressure. Any leak will be cause for an immediate shutdown and cessation of repair work.
It is our goal to complete this project safely with minimal risk to the community. Because it is our community, too.
