AWWA G480:2013 pdf download.Water Conservation Program Operation and Management
The following definitions shall apply in this standard:
1. Demand management: Strategic practices that optimize water supply, treatment, and delivery requirements to assist long term sustainability of water resources. I Demand-management measures include water efficiency improve- ments (high- eficiency plumbing fixtures, water-ficient landscaping and iriga- tion), minimizing water waste and loss (water loss control), conservation- oriented pricing, changes in water consumption practices (using recycled water for irri- gation)，and public education. Some demand-management measures can be implemented by consumers on their own, while others are implemented through utility-sponsored programs.
2. Integrated resources planning (IRP): A comprehensive form of water utility planning that encompasses least-cost analyses of demand management and supply management options, as well as an open and participatory decision- making process, preparation of alternative planning scenarios, and a recognition of the multiple institutions concerned with water resources and the competing policy goals among them. Refer to AWWA M50, Water Resources Planning, for tools to implement an IRP.
6. Stakeholders: A group, organization, person, or agency that has an inter- est in, dcision-making responsibility for, or authority over a process and is affected by or will benefit from the outcome of the process.
7. Supply management: The use of specific measures by water utilities to enhance their capability to supply water, including additions as well as eficiency improvements in the water supply infastructure. Supply management includes the use of water audits, pressure management, metering, source protection, conserva- tion, and source development that meets least -cost and other planning criteria.
8. Wastewater: A combination of the liquid and water- carried waste from residences, commercial buildings, industrial plants, and institutions, together with any groundwater, surface water, and stormwater that may be present.
9. Water conservation: Activities designed to (1) reduce the demand for water, (2) improve eficiency in use and reduce losses and waste of water, and (3) improve land management practices, such as landscaping, soil improvement, and LID storm- water retention, to conserve water.
10. Water eficiency: (1) The accomplishment of a function, task, process, or result with the minimal amount of water feasible, or (2) an indicator of the rela- tionship between the amount of water required for a particular purpose and the amount of water used or delivered.AWWA G480 pdf download.
