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.

There are not many wastewater treatment plants that can look at naturally occurring organic waste and see a renewable source of energy. However, the Village Creek Wastewater Treatment Plant in Fort Worth, Texas, has done exactly that for the last 40 years. This last year, steps were taken that could make Village Creek a net energy producer instead of an energy consumer.

Recent Advancements in Wastewater Sludge Composting
Water Engineering & Management
October 2002
Izrail S. Turovskiy, D. Sc. and Jeffrey D. Westbrook, P.E.
Many utility providers face growing problems with the disposal of the wastewater sludges (residuals) that are created as part of the wastewater treatment process. Other providers are looking to additional methods for converting the residuals into fertilizer/soil conditioner with a higher economic and social value. The new technology presented in this paper provides a composting method to address the disposal and/or use of wastewater residuals. By maintaining the recommendations presented in this paper, a Class A biosolid can be produced. This Class A biosolid provides the utility operator the maximum flexibility for its disposal or use as a fertilizer, soil conditioner, etc.

Aeration Performance of Weirs - Part 1
Water Engineering & Management
March 2001
Dr. Ahmet Baylar and Tamer Bagatur
Oxygen is vital to the life cycle common to water. It is essential to keep organisms living, to sustain species reproduction and for the development of populations. Oxygen is soluble in water in direct proportion to the partial pressure in the gas phase, while solubility decreases as temperature increases. Salt water holds less oxygen than fresh water. Oxygen enters the water by absorption directly from the atmosphere or by plant photosynthesis. It is removed by respiration of organisms and by organic decomposition. During respiration and decomposition, animals and plants consume dissolved oxygen and liberate carbon dioxide.
