Algorithm for Determining the Effectiveness of Water Conservation Measures


Book Description

An algorithm has been developed to determine the effectiveness in reducing water use by the implementation of a variety of water conservation measures. The algorithm developed may be used to estimate water use reductions resulting from the implementation of a large number of conservation measures and combinations of measures, and is designed so that it may be easily programmed as a new module within the Methodology for Areawide Planning Studies (MAPS) computer program. The effectiveness of any water conservation program is dependent upon site-specific conditions, so caution should be used in applying the numerical values for reduction, coverage, and interaction factors presented in this report. To serve this purpose, detailed references are given so that the user can utilize the sources of data to ensure that the values selected are appropriate.







Urban Stormwater Management in the United States


Book Description

The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.
