Wetland Valuation Based Upon Multi-Purpose Performance Evaluation
Wetland protection and restoration have become a top priority in water management. A wide variety of benefits are ascribed to wetland protection, e.g., flood control, water quality improvement,...
Summary of Stormwater Quality Management Practices
The control of water quality in urban runoff is in its technical infancy. Never-the-less Water Quality Act of 1987 states that stormwater pollution must be reduced to the maximum extent...
Water Technology Development and Transfer in Mexico
Mexican Government has developed the National Potable Water Supply and Sanitation Program to meet the country's water supply demands, both in quantity and quality. Two core...
A 1990's Strategy for Combined Sewer Improvements
On June 22, 1990, the Regional Water Quality Control Board issued the City of Sacramento a Cease and Desist Order. The Order required the City to examine the condition of, and flooding...

What is a Drainage Utility?
A drainage utility is: a financing mechanism, providing a stable and dedicated funding source for surface water quality and quantity control; and a governmental entity whose mission is...
A Model for the Management of Groundwater and Surface Water Rights During Droughts
A more equitable management of basin water rights could be obtained if groundwater rights were allocated as a maximum rate of withdrawal and yearly amount of water determined as an equivalent...
Conceptual Model for Performance-Based Management of Regional Water Systems
The national shift in emphasis from top-down development plan orientation in water resources, wherein the federal government assumed the dominant role, to the shared partnership approach...
Implementing Sacramento's NPDES Stormwater Permit
Between 1987 and 1990, EPA established the National Pollutant Discharge Elimination System (NPDES) permit application requirements and deadlines for stormwater discharges. During this...
