Across America, municipalities tasked with revitalizing an aging water infrastructure are facing pressure from constituents to keep their solutions both inexpensive and environmentally friendly. Can technology keep up with 21st century municipal demands? By MARK NEUMANN, general manager, RePipe California. s environmentally friendly perspectives become more the accepted standard these days, growing cities and towns are exploring ways to incorporate sustainable, environmentally-sensitive and energy-efficient products and technologies into the infrastructure and the operational profile of their communities. From familiar standbys to innovative new technologies, societies across the United States and the world are coming around to the idea that eco-friendly policies and programs can be quite friendly to a budget’s bottom line, and that going green does not just make sense, it makes cents. A 30 21st century answers to 20th century pipe One such example of a new technology using green products is an innovative spiral-wound technology system that can be used to rehabilitate damaged pipes or to rebuild existing pipelines. This technology has the potential to improve the efficiency, reliability and integrity of aging sewers, storm drains or culverts, providing an equivalent level of hydraulic capacity to what would typically be expected with new pipe installations. Spiral-wound pipe rehabilitation is being marketed as the industry’s first green solution. The technology cannot be used everywhere, but it is suitable for gravity-flow sanitary sewer and stormwater pipelines. One key to the slip-lining process’ environmental angle is that Pollution Engineering MARCH2009 The spiral-wound pipe process can be applied in an open manhole without the need for costly excavation. installation takes place from inside the existing manhole structures, eliminating the need for any excavation. The process is not brand new – it has been installed in parts of the United States for over a decade – but it continues to evolve and improve, with an eye toward environmental integrity. To date, more than 1 million feet of the spiral-wound method has been installed on the West Coast. Environmental impact is further lessened by reducing (or eliminating altogether) the need for a sewer bypass. Also, the sliplining technology releases no volatile organic compounds into the atmosphere, nor styrene into waterways.
