[1] This analysis evaluates the extent to which water quality influences the cost of supplying domestic water and the extent to which finished water quality affects household water demand from price impacts. The water demand and cost models are based on nationwide data for individual systems collected by the American Water Works Association [1996]. The water cost model estimated in this analysis indicates that factors such as the size of the water supply system, the population density of the service area, the source of water supplies, and water quality all significantly affect the cost per unit of water delivered. The water use model indicates water demand is influenced significantly by household income, household size, temperature, precipitation, the price of water, and finished water quality. Combining the results of the models allows an analyst to evaluate the full impacts of water quality benefits on municipal water supplies.INDEX TERMS: 1884 Hydrology: Water supply; 6304 Policy Sciences: Benefit-cost analysis; 6344 Policy Sciences: System operation and management; KEYWORDS: water use model, water cost model, water quality, benefits Citation: Piper, S., Impact of water quality on municipal water price and residential water demand and implications for water supply benefits, Water Resour.
A land use management plan is currently under consideration in the Turtle Lake area of North Dakota that would help preserve wetlands and allow land development for irrigation. The plan is unique because it includes a wetland component, recognizing the potential benefits to society from preserving wetland acreage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
