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.

Engineers are continually faced with reducing or attaining zero increase in runoff from pre- to post-development when designing a stormwater system. In the case of the Holland Community Hospital in Michigan, a surface pond was not an option due to limited space. The engineering firm of Fishbeck, Thompson, Carr & Huber opted for a Cultec, Inc., subsurface stormwater management system for this project.

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.

February 2003
Moving water may be an ancient practice, but that did not keep bright engineering minds from developing a more efficient way to do it. Balancing an aggressive, stormwater pipeline design concept with a conservative approach to prove its performance, the result was a new engineered stormwater system. A new, more economical system design justified discarding the old plans and redrawing them with HDPE pipe.

Holder Construction, Inc. of Atlanta was contracted to expand Gwinnett County's Cultural and Civic Center in Georgia. According to EPA's regulations and state laws, projects such as this require a NPDES Construction Activity permit.To address the monitoring side of this compliance issue, Holder Construction regularly uses traditional stormwater monitoring systems. However, in this instance, they decided to implement both a traditional system and a newer system, created through a partnership of WRT and NIVIS LLC. Holder Construction did so in order to compare results and operational efficiencies between both types of units.
