October 2002
Dennis F. Hallahan P.E.
In 1997, EPA and Congress officially recognized onsite wastewater treatment systems (commonly referred to as septic systems) as a viable, long-term solution for treating wastewater.

Dave Averbeck, Pentair Water Treatment
Recent trends in home construction and strict interpretation of plumbing codes are forcing the water conditioning industry to offer systems with higher flow ratings. While the need for higher flow rates in larger homes is genuine, the actual flow rates that are encountered are likely to be less than those predicted using the traditional fixture count method to calculate flows. The system manufacturer needs to carefully consider all components used to assemble the system when designing a water conditioner to meet a specific flow requirement.

Pumping System Helps Town Bring New Development Up to Code
Water Engineering & Management
November 2001
When a Leicester, Mass., developer planned a subdivision of 16 houses at the same elevation as the town’s water tower, he was faced with the problem of how to provide minimum water pressure mandated by the state. He had read about the use of a Goulds Aquavar pump control system in high-rise commercial buildings, and the idea of a variable-speed system appealed to him. He thought a pressure-demand system might do the job cost effectively.
