Conservation and drought management ranked high by 90% of respondents to TMWA’s (Truckee Meadows Water Authority) survey of topics of importance to be addressed in the 2020-2040 TMWA Plan 5 year update. And, as before, TMWA talks generally about conservation but has no definitive goals and no new actions to achieve water efficiency to reduce per capita demand for its customers.
TMWA’s update, like the previous plan, doesn’t look to water efficiency instead calling for “enhanced conservation” by its customers only during drought. TMWA’s “Enhanced conservation” asks customers to reduce water use by 10% during level “2” to “4” droughts for between 3 months to a maximum of 5 months. In a level 1 drought or non-drought, TMWA’s plan update calls for “standard conservation”. But standard conservation offers no incentives, strategies or goals to reduce per person water use and appears to rely exclusively on an even-odd address, 3 days per week outdoor watering. TMWA has no plan to implement programs to help its customers be more water efficient over the next 20 years of the plan during all conditions. Hardly forward looking for a desert community with less than 7″ average annual precipitation, long, hot, dry summers, and rising temperatures year-after-year.
This year Reno saw just 3.81 inches of precipitation in the form of rain and snow since October 1, 2019 – over 10 months. And, Reno’s summer temperatures are hot and likely for overall average annual temperature to approach or even top those of the past. Indeed, we live in a desert and need to be efficient and conserve the little water the region has to support people and the environment.
A Chart in TMWA’s plan update shows that for the past five years water use in its service area has been right around 150 gallons per person per day (GPD). That’s more than many other western cities including Las Vegas where customer water use has declined to 120 GPD. And, Las Vegas expects to continue to lower the GPD through its water efficiency programs. TMWA should be doing the same to lower its need for expensive engineering solutions and new groundwater sources.
Too often water runs down the gutter from over-watering and inefficient or broken outdoor sprinkler systems. Once water is running down the gutter it will eventually end back up in the Truckee River with contaminants of all kinds – discarded waste and oil being common. Water waste becomes more common with ineffective incentives for customers to conserve. People-unfriendly, grass-fronted roads in business districts send water spraying into adjacent streets. These water wasteful spaces offer little to the public and could and should be replaced with appropriate water conserving landscapes, instead. With proper water efficiency incentives adopted, TMWA’s plan update could encourage appropriate low-water landscaping that offers more interesting plantings that offer more shade and function. TMWA needs a plan update that identifies implementing better options for customers to save water and lower overall demand.
The 2020-2040 TMWA Plan update doesn’t contain any new initiatives or changes to its water pricing structure. While TMWA’s website promotes the plan as an call to action, the plan update contains no new direction regarding water use.
Of the customer insights collected so far, the top concerns are related to two topics: population growth and extreme climate variation. TMWA’s approach to these issues are woven throughout this plan.(https://tmwa.com/article/tmwa-seeks-public-input-for-draft-2020-2040-water-resource-plan/)
TMWA, however, continues its past approach of drilling wells, diverting more water, and pumping water underground just like its previous plan. Other cities have consistently seen the error in this approach and have found customer friendly ways to reduce demand and delay or eliminate the need for expensive new water infrastructure. Further, TMWA’s own projections show that its approach will lead to shortages under climate change scenarios. Nevertheless, the plan essentially ignores these results saying that the problem will only occur in-the-future and outside of the planning horizon. Such an approach lacks credibility and puts the entire plan in doubt.
