WEBINAR SUMMARY

Sarah kicked off the webinar by introducing how seasonal changes in climate along with increasing
trends of global warming place stress on local water supply systems during periods of peak demand.
Much of the increase in water demand during the summer months can be attributed to outdoor use in the
landscape. In instances of extreme water supply shortages, many communities have turned to restrict
water use through mandates and legislation. Shared commercial landscapes face unique challenges to
manage outdoor water use but those challenges can also offer creative opportunities to cut water waste.
Cutting water waste outdoors is an easy way to protect your local water supply and save money on your
water bill.

AWE UPDATE: LIESEL HANS

Liesel provided an overview of Alliance for Water Efficiency (AWE) and reiterated their mission to
promote an efficient and sustainable water future. AWE has several useful resources available on their
website (https://www.allianceforwaterefficiencv.org/) including reports on the market readiness of
landscape transformation, the effectiveness and municipal irrigation restrictions during drought, and
sustainable landscape guides. AWE also has an initiative, "Financing Sustainable Water", aimed at
guiding utilities through rate structures.

The featured speaker, Jeff, introduced the Town of Gilbert's
Landscape Water Budget Program 2.0. The program began in
2009 when the town identified the opportunity to create water
budgets for Homeowner Associations with more than one acre
of turf. Turfgrass area was measured through aerial photos. A
budget of supplemental water needs for the space was
estimated using these areas and the historical
evapotranspiration data. The conservation office then
compared the budgeted volume of water to actual use and
found that these identified spaces had 381,031,000 gallons of potential water savings. Using this data
Gilbert decided to target the HOAs with large potentials for water savings and encourage their enrollment
in the Water Budget Program. The program established a goal to get all participants within 20% of the
budgeted amount of irrigation, and all HOAs that fell within 10% of their calculated budget are given an
exceptional status. To reach this goal the conservation office provided monthly updates to the HOAs

involved clearly stating the status of their water use, how much precipitation they had received and how
the city's water budget fared overall. The program's success led to tremendous growth and the Town of
Gilbert launch a new version, Water Budget Program 2.0, which updated and automated the process of
managing increasing numbers of participants through a platform called, Waterfluence. It has the capacity
to easily record water use trends and detect and filter sites with monthly spikes, daily spikes, potential
leaks, etc. Using this data, the Town of Gilbert is able to work with high water users quickly and
effectively to identify and mitigate the causes of high-water use. Their program now manages 298 sites
making up 52.6% of all non-single family residential landscapes and in 2022 they saw 105,000,000
gallons of savings and $291,900 in avoided water costs. Participating sites that are within 20% of their
budget for the year are awarded the title and label, "Water Wise Landscape." This past year the program
awarded the title to 119 sites and those communities are seeing increased interest and market value
from the label.

CONCLUSION

The Landscape Water Budget Program of Gilbert, AZ continues to grow with continual interest to work
towards capturing all potential water savings. The automated nature of the Water Budget Program
Version 2.0 collects more information for the stakeholder and allows the conservation office more time for
outreach and site visits. The success of the Water Budget Program 2.0 has yielded inspiring results and
advances conservation efforts of the Town of Gilbert. Wth growing trends of drought in the west it is now
more important than ever to minimize water over-use within the landscape. Water Budget Programs can
be a useful tool for municipalities to protect their water sources.

SPEAKER QUESTIONS AND ANSWERS

Q: Do you have plans to update water budget goals with growing drought in the West?

A: Yes, over the past decade or so the goal of the Water Budget Program has been to reduce excess
water use, to not use more than we have. The town of Gilbert has several sources of water supply to
supplement given changes in water availability, but in the extreme case that those do not suffice, they are
also prepared to ask participants for water deficits. In addition to the attention given to irrigation, they also
plan to educate members of the community on other best management practices to maintain drought-
tolerant landscapes with a particular emphasis on maintaining tree canopies.

Q: How did you manage the need for staff as the program grew?

A: The digital platform of Version 2.0 allowed for a large decrease in hours needed to maintain data and
send out monthly email updates. This allowed staff time to focus on site visits and enroll more sites into
the program.

Q: What format did you use to reach out to HOAs in the beginning of the program?

A: HOA board members and managers wear a lot of hats and getting their attention initially was difficult
and slow. With consistent contact and time managers began to see the benefits of participation in the
program and through word-of-mouth between HOA managers the program began to grow. Once the
program had enough participants, they were able to establish value in the community Water Wse label
and continue to engage interest in the program.
