Municipal Water Conservation

Unfortunately, not all cities in Texas are pursuing conservation as aggressively as they could. The Texas Living Waters Project’s 2010 report Drop by Drop reviews conservation programs in 19 cities around Texas to determine the extent to which aspects of municipal water use efficiency have been implemented. Our findings indicate that the quality and extent of water conservation programs in Texas’ cities vary considerably. While some water utilities have begun to realize the potential of water efficiency, many others have yet to take full advantage of the cheapest, most reliable, and most sustainable source of water – the one that’s already on tap.

To reduce local water use, we recommend that cities and local water utilities should adopt the following common-sense measures with a proven track record for success.

1. Implement fair water rate structures. Utilities should have a strong tiered rate structure with affordable prices for those who use water efficiently and significantly higher water rates for customers who use excessive amounts of water. The additional revenue generated should be dedicated to funding water conservation programs. Read more: Designing Water Rate Structures for Water Conservation and Revenue Stability

2. Establish water conservation goals. Texas cities are required to create conservation plans with water use reduction goals, however many cities set easily achievable but not very impressive targets. Water utilities with relatively moderate rates of water use should set goals that meet the 1% annual reduction/140 gallons per capita per day (gpcd) recommendation made by the Texas Water Develop Board Water Conservation Implementation Task Force. Utilities with higher rates of water use should set more aggressive goals.

3. Implement toilet replacement programs. New high-efficiency toilets can save 12,000 gallons annually over older models. All major Texas water utilities should tap into this low-priced and reliable water source by replacing as many pre-1992 toilets as is practical and cost effective.

4. Fund water conservation efforts. All major Texas water utilities should create water conservation departments and fund this department adequately. Water conservation should be a separate line item in the budget, and cities should make sure conservation dollars are used effectively.

5. Adopt outdoor watering ordinances. To ensure that water for landscaping is used as effectively as possible, cities should encourage once-a-week watering and restrict lawn watering to no more than twice a week even during years of normal rainfall. Landscape watering during the heat of the day should be prohibited throughout the year.

6. Establish retrofit programs. A standard showerhead purchased today will save customers roughly three gallons per minute. Cities, particularly those cities seeking new water supplies, should take advantage of the dependable water saving from such new technologies by creating cost-effective retrofit programs.

7. Educate the public. Educating the public about ways to use water efficiently can reduce water use, build public support for additional conservation measures, and improve a utilities image as a wise steward of our natural resources. Large and moderate-sized utilities should invest in reasonable public education programs.

Case Study: Water Conservation in San Antonio

Efforts to reduce water use in San Antonio over the past 3 decades have been tremendously successful. As a result, San Antonio is able to use the same quantity of water to serve many more people than it did over 30 years ago, despite the city’s tremendous growth in population over that period.

Conserving Water to Prepare for Drought

Ongoing water conservation programs are the single best way to set the stage for effective drought response at both the local and state level.

Reducing Outdoor Water Use

Outdoor water use, which mostly means lawn watering, represents one of the largest uses of water in urban areas. Texas cities should implement seven efficiency measures that have a proven track report to reduce this significant water use.

Role of State Government

The State of Texas must take a lead role in encouraging efficient use of limited water resources in communities throughout the state. The Texas Living Waters Project recommends a number of actions to help achieve improved local water conservation.

Top Three Water User Categories in Texas

Water is used for a variety of different purposes in Texas, including municipal, irrigation, livestock, manufacturing, mining, and steam-electric power generation. The top three major water user categories in Texas are municipal, agricultural, and industrial.
