Water Conservation Toolbox: Programs for Water Suppliers

 

Water utilities across North America save considerable amounts of water through water-efficiency programs. Climate and water availability typically drive the aggressiveness of communities' water conservation programs, with more substantial efforts being made in the southwestern states and Florida. Although these areas may have more significant shortages and more aggressive water use reduction programs, the conservation principles applied there are applicable to all areas regardless of the climate.

Implementing a combination of programs tailored to your community's needs is the most effective way of reducing water use. To assist you in selecting water conservation programs, this Toolbox provides information in the following areas:

• Regulatory Programs
• Incentive Programs
• Education Programs
• Rate Structures
• Stormwater reuse

Implementation of these programs can shave peak use to avoid unnecessary capital expenditures, manage resources during emergencies, improve watering efficiency or reduce overall use. Benefits and costs of water conservation.

Education Programs

Evaluating the impact of water conservation education is difficult.  However, providing conservation messages on a regular basis through a variety of approaches (bill stuffers, newsletters, press releases, school outreach) helps to ensure the messages reach a large audience. Minnesota Statute 103G.291 requires that water suppliers have an education program as part of their conservation plan.

• Water: Use it wisely
• H2ouse
• WaterWiser
• U.S. Environmental Protection Agency
• Minnesota Native Plant Guide, MN Department of Natural Resources
• Water Conservation, Elk River, MN, Municipal Utilities
• Canada, Water Saver Kits, City of Vancouver
• Model water conservation brochure
• Tips and Practices, Metropolitan Council
• Industrial, Commercial and Institutional Water Audits, Alburquerque Bernalillo County Water Utility Authority
• Publicly Owned Treatment Works, Minnesota Technical Assistance Program, University of MN

Rate Structures

Minnesota Statutes, section 103G.291, was amended in 2008 to include a requirement for public water
suppliers serving more than 1,000 people to adopt a water rate structure that encourages conservation. For more information on conservation rate structures visit the Department of Natural Resources website.

Stormwater Reuse

Communities throughout the United States are using Stormwater as an alternative water source for irrigation. As the percent of impervious surface throughout the Twin Cities metropolitan area increases, stormwater runoff increases impacting water quality. Harvesting rainwater and using retention ponds to capture stormwater runoff for subsequent use can reduce the impacts of urban runoff, while conserving our water resources.

• Retention and Irrigation, California Stormwater Quality Association
• Stormwater Reuse, University of Central Florida
• Stormwater as an Alternative Source of Water Supply: Feasibility and Implications for Watershed Management, University of Florida
• Lawn and Landscape Irrigation Systems, Medina City Code
• Stormwater Manual: Drinking Water Source Areas, Minnesota Pollution Control Agency
• Stormwater calculator, Green Values
