AWWA G560-22 Stormwater Management for Water Utilities

The purpose of this standard is to define the minimum requirements for a water utility’s stormwater management program, including management of stormwater on water utility sites, addressing water quality and water quantity issues, planning and design of stormwater programs, and incorporation of stormwater in integrated water resource planning and management. Stormwater management and flood control are typically the responsibility of local governments, regional flood districts, and sometimes federal agencies such as the U. S. Army Corps of Engineers (USACE), to which the utility oftentimes provides water services. Consequently, the utility will often be working with the government’s relevant programs and activities already. This standard outlines elements for water utilities to consider in managing their own stormwater and stormwater generated outside their jurisdiction.
