The Standard Septic System: Still an Effective Choice for Onsite Wastewater Treatment
Water Engineering & Management
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. This was an important designation since nearly 40 percent of new homes in the United States use this type of system to treat household wastewater.

Keeping Meters On Line: Accurately Measuring Drinking Water and Sewage
Water Engineering & Management
September 2002
Rodney Johnson
Detroit Water & Sewerage Department (DWSD) has a high stake in keeping its flowmeters up and running with calibrated accuracy. This is especially true for its 278 wholesale water meters used in its vast network of distribution lines that serve 126 communities. It also is true for metering sewage inputs from wholesale customers for its Wastewater Treatment Plant. This article focuses on a unique answer that DWSD found for keeping its magnetic meters online by means of a portable electronic system that verifies and certifies calibration, all done in-line.

Stormwater Retrofitting to Protect Drinking Water Reservoirs from the Impacts of Urban Runoff - Part 2
Water Engineering & Management
July 2002
James D. Benson, AICP, and Melissa Beristain
The Kensico Reservoir Stormwater Management Program is designed to reduce fecal coliform bacteria and turbidity delivered to the reservoir by controlling and treating stormwater. The first phases of the project, assessment of the watershed, site selection and the screening and design of stormwater control and treatment facilities, were completed in July 1998. Facility construction began in the spring of 1999 and completed early in 2001. DEP has committed to monitoring and evaluating facility performance and maintaining the facilities.

Decentralized Wastewater Treatment: Community Building and the Watershed Agenda
Water Engineering & Management
May 2002
Craig Lindell
Decentralized wastewater treatment presents us with a range of possibilities for community preservation and watershed management. However, these possibilities remain obscured by the limitations of the onsite codes and unforeseen by municipal wastewater authorities unaware of decentralization or reluctant to explore its range and potential.
