Sustainable Land Development Today - November/December 2007 - (Page 42) WASTEWATER service calls. If service is required, its one-piece core eliminates the need for in-field troubleshooting and servicing — the pump core can be quickly pulled out and replaced. Other Benefits The E/One LPS is a closed system and resistant to groundwater infiltration and runoff, which is a problem in the region for traditional gravity systems. And the system is nearly invisible, with no manhole covers. The pump lids are at ground level and easily camouflaged by simple landscaping such as flowers or plants. Because the pipes are smaller than traditional 24-inch mains, the installation is kinder and gentler to the terrain. To accommodate access to existing lines during build-out at Fairfield Bay, Flo Hot/Wet taps were used to install the grinder pumps to the pressure system, which eliminated cutting into “hot” pressure sewer mains. A redundant check-valve was located next to the tap. This facilitated the ability to repair service lines and components without backflow. Today there are 1,886 homes with approximately 1,591 connected to sewer, of which 600 are on pressure. The homeowners own their grinder pumps and are responsible for power and repair costs. Wastewater Corporation, a subsidiary of Fairfield Bay Community Club, owns, operates and maintains four sewage treatment plants and 16 major lift stations. They boast an onsite laboratory, which runs wastewater samples for EPA NPDES reporting. The corporation also installs and services all 600 E/One grinder pumps. Wastewater Corporation has a staff off eight full-time employees, including two full-time treatment plant operators, two maintenance workers for the plants, lift stations, and grinder pumps, and one dedicated worker for all grinder pump service and repair. There is always one maintenance worker available on call 24 hours a day, seven days a week. This organization follows strict repair protocol, and keeps detailed records of each installation, repair, and each pump by serial number. It’s In The Numbers The most powerful recommendation, according to Tyler, is performance. “From 1977 to present, we’ve serviced these 600 pumps; a total of 951 repairs, 89 core replacements, out of a total 10,765 pump years of operation. The mean time between service calls is 11.3 years. That’s years!” Over the course of the past 30 years, E/One has supplied Fairfield Bay with two series of grinder pumps. From 1977 to 1995, a total of 420 “200 Series” pumps were installed, and from 1996 to 2007, a total of 180 of the newer 2000 Series pumps were installed.

E/One and Fairfield Bay have had an excellent relationship during the past 26 plus years,” Tyler said. The spirit of cooperation continues in the design of the company’s newest grinder pump, the Extreme series, according to Tyler “All of the large-scale users got a voice in the design of this latest pump, and we appreciated that, because we all want a pump that’s bulletproof.” SLDT for the Decentralized Market Circle 173 • or www.LandDevelopmentToday.com/adinfo http://www.Adenus.com http://www.Adenus.com http://www.LandDevelopmentToday.com/adinfo
