In June, the Water Environment Research Foundation (WERF) released two stormwater publications that are available free to WERF subscribers. The first, Tools For Evaluating The Benefits Of Green Infrastructure for Urban Water Management, discusses criteria, metrics, and protocols for measuring green infrastructure benefits. This discussion includes data collection and performance measurements, as well as two important cost analyses — triple bottom line and life cycle cost analysis.
WERF also recently released Stormwater Non-Potable Beneficial Uses and Effects on Urban Infrastructure. This publication covers international beneficial stormwater use projects in both developed and developing countries under various climatic conditions. It also discusses stormwater storage and treatment options for meeting water quality criteria and includes guidance on calculating storage volumes and supplemental landscape irrigation.
