The CSO controversy
Article Abstract:
The national combined sewer overflow (CSO) policy released by the EPA prohibits more than 900 cities from discharging untreated sewer and stormwater effluents into rivers, lakes and streams. However, numerous municipal governments find it very impossible to comply with the directive because of the cost of eliminating CSOs. For instance, Wheeling, VA, has 211 CSO outfalls that must be eliminated. It will cost the town about $400 million to build a new separate stormwater system. The amount is something that Wheeling cannot afford since 1/4 of its residents live on low incomes and 17% below the poverty level.

Cold-climate solution
Article Abstract:
The South Anchorage Snow Disposal and Sedimentation Basin in Alaska was developed to treat water discharges from commercial, industrial and residential areas including runoff from snow-disposal sites. The project was developed in compliance with EPA's National Pollutant Discharge Elimination System program requiring a permit for a separate stormwater sewer system to control urban runoff. The sedimentation basin and wetland complex was expected to minimize the turbidity observed in local streams.

Overflow control
Article Abstract:
The city of Houston, TX, developed the Greater Houston Wastewater Program, a project designed to handle excess sewer volume brought about by the wet weather. This initiative requires the construction of overflow control facilities and adoption of flow data analysis techniques. Initial results allowed engineers to make the necessary flow adjustments and save up to $5.8 million in downstream project costs.
