As portions of the Peachtree Water and Sewerage Authority (PCWASA) system are being evaluated to determine their structural integrity, other portions are being rehabilitated. Such is the hectic process and schedule of sewer system capital improvements.
But how do you rehab a sewer line within an exclusive golf course community without disturbing the landscape, layout, or membership?
An example of such a capital project took place recently within the Planterra Ridge Golf Course in Peachtree City, where PCWASA utilized a modern marvel to rehabilitate aging sewer lines within one of the more highly visible areas of the system. And the Authority did so with minimal inconveniences to customers or disturbances to the environment.
PCWASA contractors from Brent Scarbrough and Company completed the Planterra Ridge sewer rehab project by installing Cured In Place Pipe (CIPP) on lines that were in close proximity of the new Lake McIntosh. The CIPP process improves the consistency of these sewer lines to reduce the risk of any problems at the site of the reservoir impoundment in the future.
The use of CIPP seals off leaks caused by cracks, fractures, misaligned joints, roots, or other problems that are evident and common in every sewer system. The new CIPP adds structural integrity to the existing pipe, extending its useful life span. But in addition to using the strongest materials available, CIPP is an environmentally friendly process for sewer line rehab, while providing a cost effective return on investments in capital improvements.
In the case of rehabilitating the PCWASA sewer lines running throughout the Planterra Ridge Golf Course, Authority officials surmised that CIPP Installation was the most appropriate methodology for sewer pipe rehab in this instance. As a result, when PCWASA contractors were busy re-lining sewer pipes at Planterra Ridge with CIPP Installation, those playing golf around the scheduled work were hard pressed to know the crews were even there.
“With pipe lining technology, sewer line rehab doesn’t require trenches to be dug or dirt to be excavated, as would be the case for open cut repairs,” says Hogan. “From one manhole to another, a sewer line can be completely re-lined to a condition good as new, without the mess or stress to the property or landscape – in this case the golf course at Planterra Ridge. We completed this project without incident, and it was a great success.”
As for other rehab work, when RedZone Robotics finishes collecting data on the status of PCWASA infrastructure, the Authority will locate additional areas in need of rehab attention, prioritizing projects much like the one recently completed at Planterra Ridge. RedZone is the PCWASA contractor assisting the Authority with a conditional assessment of all sewer lines within the system, as the innovative CIPP pipe lining process and other methods of sewer line rehabilitation will follow as necessary, says Hogan.
“We will continue with other lining projects as we discover needs and as our budget allows,” adds Hogan. “This work will be included in our master planning and future budgets. The lining process is just one of the methods in our toolbox that allows us to maintain and extend the life of the system.”
