Suggested in stage 4 or 5, outdoor watering may be limited to every other week instead of weekly Cut off all outdoor water usage at some point in extreme drought and clarify that sooner rather than later in stage 5. 6/26 Clarification: include language in Stage 5 that anticipates DWDR and acknowledged need for potentially more severe restrictions such as cutting off all outdoor irrigation. Have we evaluated this measure [patio misters limited hours] in terms of actual water savings? Have we evaluated this measure in terms of overall climate goals? For example, if a restaurant could provide outdoor seating during lunch with patio misters, versus expanding their air-conditioned seating in order to provide lunch seating, which is a better outcome for our overall water use and climate goals?  New pool permits: Has there been an analysis of the number of pool permits per year from 2016- 2024? Anecdotally there seems to be a big increase in home swimming pools, in both existing and new construction. If there has been an increase in new pool permits, do new pool permit moratoriums need to be instituted in an earlier drought stage given there are more of them and may have a greater effect on water use than in previous DCPs? Look at number of private pool permit/increase in number of private pools since last DCP/WCP was done. Look at pool refilling provision.

The response to the question I asked reiterated that it offsets costs and the rebate is based on the number of zones or cooling tonnage, which is helpful but it doesn't tell me what the rebate would be relative to the cost to the customer to hook up.

Policy Decision - Will be discussed and considered 22 city. Which leads to the next point. Paul DiFiore 5/20/2024 Written email feedback Industrial Users/SERs WF24 My main concern with our Drought Contingency Plan and Water Conservation Plan is that over the next decades, Austinites will work diligently to conserve water, yet we will fail to manage where our supply goes. As it stands, all our hard-earned gains on water conservation are vulnerable to being instantly wiped away by massive new industrial users coming onto our system. It’s a glaring hole in our planning process. And it exists because of an outdated east-west inequity in our city, which allows for projects in the so-called Drinking Water Protection Zone to receive heightened levels of public scrutiny while those in the so-called Desired Development Zone get staff approval with no boards or council oversight. Consider the anticipated goals in the Water Conservation Plan: by 2029 we are hoping to save 245 million gallons of water each year through the increased use of our reclaimed water system. Likewise we are hoping to save 266 million gallons of water each year through landscape transformation. Each of those monumental efforts—which require massive resources from utility staff and buy-in from tens of thousands of Austin residents—would be more than canceled out by a new industrial user like the next Tesla coming into our system. That’s an unacceptable way to plan for the long-term future of our water supply and demand, and it should be addressed in the WF24 update. I disagree fundamentally. Here’s the difference between a gallon of water consumed by a household, a small business, or even a government building, and that same gallon consumed by Samsung (by far the largest user of water in Austin): one uses it for their livelihood or for public interest activities, the other strictly for profit. The return on every dollar spent on water by an industrial user is far higher. These two distinct forms of water consumption cannot be evaluated or weighed in the same way– nor should their service extension requests be processed the same way. Yes, people in Austin work at these high-water-consuming facilities, and the companies pay taxes (giant tax incentives and subsidies notwithstanding for the sake of argument), so it can be claimed that we all receive some direct and indirect benefits from their presence here. However, we locals also receive burdens, one of which is the huge strain on our water resources. Meanwhile, the corporations and their distant shareholders see their profit margins increase as they build more and use more of Austin’s water. So, we should think twice before we turn on the tap to new industrial users. The analysis may be complex, but I’m confident we have the expertise to do it. It’s our responsibility to consider whether welcoming these facilities is, on balance, in the best interest of the I agree completely. Balancing competing priorities so that the public interest ultimately prevails is the job of our elected members of City Council. We’ve entrusted them, as well as their appointed community members on boards and commissions, to study the issues and make sound policy choices for the benefit of Austin. That is exactly why it makes no sense to cut our representatives out of major decisions like whether or not to hook up a new industrial user of the city’s water. A transparent process of public oversight and input is critical to the healthy functioning of a democratic local government. Right now, we don’t have that when it comes to the approval of service extension requests. Even AW staff themselves admit that determining who should have access to water and who shouldn’t is not a choice they want to make. That’s fair. Many times, it’s an easy call: for the hundreds of relatively minor SERs to residential developments or small businesses, administrative approval is surely appropriate. But for the largest and most impactful industrial projects, which will be few in number, we must have the capacity to pull them out of the pile and subject them to a higher level of scrutiny. We also need to move past the old dichotomy between the so-called “Drinking Water Protection Zone” and the “Desired Development Zone” which has led to decreased environmental quality on the east side of Austin for so many decades. I’m stunned that our city still maintains policies that contribute to longstanding and tangible inequities in our communities. My proposal therefore is simple: extend the same level of public oversight that projects west of Austin receive to major projects east of Austin. That includes water planning and service extension requests, especially for large industrial projects, which are fundamentally different than other regular uses. I recommend, as part of the 2024 Water Forward Plan updates, that Austin Water change its policy regarding service extension requests. The Council should set certain criteria, such as a threshold of annual water consumption, above which any service extension request must be reviewed by the Environmental Commission, the Water and Wastewater Commission, and ultimately approved or denied by the full Council, as is the case currently with SERs west of Austin. As we all buckle down in one of the worst droughts in our state’s history, we cannot afford to erase the gains of our conservation efforts because we unnecessarily abdicate control over water planning. The people of Austin and our representatives on the Council must have a say in these critical decisions.

Madelline Mathis 5/21/2024, 5/29/2024 Reuse WF24 Written email feedback; 5/29 WF24 Working Group Meeting Page 18 Drought Response Stage 4: Operation of splash pads during limited hours. Splash pads are generally publicly owned by a City or HOA and used for small children. Many splash pads do not operate continuously but are operated by a button. I notice that Stage 4 suspends new pool permits but does not limit filling private swimming pools. This feels like an inequitable distribution of burden for water use reduction to limit the availability of splash pads which are a public recreation amenity but not filling private swimming pools. I recommend allowing splash pads as one would expect that during a hot summer in Stage 4 drought there would be limited opportunities for outdoor activity for children other than a splash pad. Sarah Faust 4/24/2024 Drought DCP Written email feedback Does not think limiting hours at splashpads should be an option during drought - should look at how much water is actually saved by turning them off. Sarah Faust 4/25/2024 WFTF Meeting Drought DCP Consider a really focused outreach campaign on outdoor watering, including partnerships with local news outlets to list watering days every night during the weather forecast, as well as drought triggers.

Suggests using partners to publicize the need for water conservation. A lot of reliance of enhanced marketing of drought related info to the public. Encourages AW to think about outreach and marketing plans on residential irrigation particularly. Look at outreach and marketing budget and bump it up to get better community understanding. Make sure people know their watering day. AWU immediately needs to launch a high profile education program on the drought and reducing water use as temperatures rise and we are headed towards repeat or worse drought of record. Most consumers are not aware of the current drought stages and associated restrictions. Understanding that it is very hard to gauge the effectiveness of outreach customers, and the response to comments provides that the outreach has not been reduced, we need to evaluate if the awareness has been reduced and we need to reevaluate the effectiveness of outreach. I have been inquiring with alot of people I interact with what their knowledge is of Austin Water's residential outdoor watering restrictions. Do you know what days and times you can water? Do you know what drought stage we are in? People that I consider to be very tuned in to the environment and government do not know the answers to these questions. The information below is very specific but I provide it just to offer some suggestions because for alot of people that I have asked the messages about outdoor watering are just not getting through.  The main graphic AW uses to explain watering schedules shows Residential, Commercial, and Public Schools watering days together in one graphic. It would be great to also focus messaging on Residential and Commercial separately. Maybe a version with just residential and one with just commercial to make it really easy to decipher. Also present the message in the reverse form. Residential: No watering Monday, Tuesday, or Friday.  Consider if the people in charge of "Public Schools" watering, could be reached through another more direct channel than the same graphic as all residential customers.  Sarah Faust 4/25/2024 WFTF Meeting Sarah Faust 4/25/2024 WFTF Meeting Education/O utreach WCP Education/O utreach WCP Sarah Faust 5/20/2024 Written email feedback Education/O utreach WCP Due to low participation of incentive programs, suggests strategies for PIO beyond social media such as reaching out to nurseries and landscapers to increase participation.

The new water plan doesn’t do anything to address the deficiencies in the old plan. i.e., what didn’t work. The new plan needs to identify specific measures and associated projected water savings. Overall I would like to see these goals reinstated along with an explanation of a very aggressive program that would explain strategy by strategy what it would take to meet those goals, with estimated water savings by strategy. Sarah Faust 5/20/2024 BMPs WCP Written email feedback Suggests discussing the role reuse plays in the GPCD number. As reuse rises, may not be as accurate GPCD if we keep doing it in this way. Commented that the presentation mentioned that the rate is lower because we are waiting for reuse to come on - interested on how we are counting reuse, onsite reuse which we don't have a way to count, but we are expected per capita water demand to go down based on that. On centralized system we do know - are we separating out centralized reuse, are we counting it as water conservation? How are we approaching that? Thought it was interesting how we count centralized reclaim system, is like water loss - would be good to separate out and show what portion of that water supply is serving.

Community-scale Sewer Mining -- Yes, but requires more treatment for outdoor irrigation uses. Unless additional treatment to remove pfas is added to wastewater there is risk of spreading hazardous materials and effecting soil health if used for outdoor irrigation. Community-scale Stormwater Harvesting -- Yes! I would make sure treatment is sufficient of the stormwater. Also would like to see it balanced with green stormwater infastructure such as bioswales and rain gardens so that rivers, creeks and streams as well as the aquifer still has ability to benefit from precipitation. The green infastructure will do so by slowing runoff and aiding in water perculation and filtration. ASR -- Potentially depending on costs. Cone of depression need to be researched and taken into account for optimal placement to not have negative impacts on local rivers/creeks/springs and streams that make Austin so beautiful. Contaminants such as PFAS need to be for and the introduction of aeration and effects on arsanic etc need to be fully examined. Those on well-water nearby will need to be kept informed and if arsenic mobility occurs potentially have financial resources available for them to filter that contaminant.
