Ending Odor Complaints
Water & Wastes Digest
May 2004
A long-running odor problem was solved by tapping a 30,000-cfm-capacity biofilter array into a 14 mgd average, 55 mgd maximum sewage transfer line. The line discharges into underground junction box, with the odor control system’s main collection duct evacuating box headspace air above ground for humidification and biofiltration before discharge to atmosphere through fan stacks.

Today, there is legislation to eliminate combined sewer overflows. Heavy fines are levied by the EPA against communities that violate this law. The EPA has been reasonable with enforcement because the costs are great--not to mention that it will take time to expand the infrastructure. However, as municipalities and utilities have learned, eliminating overflow events is a must.

Watertight Storm Sewer Group
The City of Chesapeake, Va. is located in the region called Hampton Roads, the 27th largest metro area in the country with more than 1.5 million residents. With an annual rainfall of approximately 48", its designers must contend with the prospects of determining where 294 billion gallons of water will go. A large share of this rainfall will find its way into the storm sewers. Last year, the City Council appropriated an extra $467,600 for contract cave-in repairs. The City of Chesapeake has recognized this problem and is developing a program to address it.

Plastic and Plastic Lined Pipe
Water Engineering & Management
September 1967
George E. Symons, Ph.D.
In about 1965, a specially designed plastic pipe, termed truss pipe, was introduced in sizes of 8-, 10-, 12-, and 15-inch diameters. In 1967, a British manufacturer announced the production of extruded polyvinyl chloride pipe (PVC) in diameters up to 16 inches, with the future possibility of producing up to 30-inch pipe. These developments undoubtedly will lead to the wider use of plastic pipe for sewers.
