Council Committee, Boards and Commission Action: February 14, 2024 - To be reviewed by the Water & Wastewater Commission. February 20, 2024 – To be reviewed by the Resource Management Commission Additional Backup Information: This action is one of four proposed Council items related to implementing Austin Water's new "GoPurple Program" to accelerate the expansion of Austin's centralized reclaimed system and onsite reuse. These are essential strategies in Austin's Water Forward plan to meet long-range needs for a secure and sustainable water future. City Council adopted an ordinance on September 30, 2021, to amend City Code Chapter 25-9 (Water and Wastewater) establishing water benchmarking, expanding Reclaimed Water Connection requirements, and adding Onsite Water Reuse requirements. The ordinance also required the City Manager to provide City Council with a report and possible actions for consideration concerning the impact of the requirements for an Onsite Water Reuse System and the expansion of the current Reclaimed Water Connection mandate on housing affordability by September 28, 2023. The required report was provided to City Council on October 25, 2023, along with recommendations for additional code amendments to address impacts to housing affordability from the new requirements. City Council adopted ordinances in November 2023 to defer the effective dates for Reclaimed Water Connection and Onsite Water Reuse requirements for large development projects until April 1, 2024 to allow more time for consideration of the proposed ordinance changes and to establish exemptions to the requirements for certain affordable housing projects. Onsite Water Reuse System Requirements In December 2020, City Council adopted the Onsite Water Reuse Systems ordinance to regulate the collection, treatment, and use of alternative water sources for non-potable uses in multi-family and commercial buildings. Onsite water sources include rainwater, condensate from heating/air conditioning Systems, foundation drain water and graywater from certain sinks, bathing, and laundry. In April 2021, Council approved an initial Pilot Incentive Program to encourage voluntary installation of Onsite Water Reuse Systems prior to initiating regulations to make Onsite Water Reuse Systems mandatory for certain development projects. In September 2021, Council adopted an ordinance to require an Onsite Water Reuse system for all new commercial, multi-family and mixed-  Item 9 # 24-4073 Water & Wastewater Commission: February 14, 2024 Council: March 7, 2024 use site plan applications submitted on or after December 1, 2023, for development projects with a gross floor area of 250,000 square feet or greater. This action will amend City Code Chapter 15-13 (Regulation of Onsite Water Reuse Systems) to specify the required Onsite Water Reuse sources (rainwater and air conditioner condensate) and required non-potable end uses (irrigation, toilet/urinal flushing, cooling, and laundry) to meet the Onsite Water Reuse mandate for large development projects. They also add clarifying language to the treatment, monitoring, and reporting requirements to address questions received from project applicants during the voluntary, incentivized Onsite Water Reuse program period that began in 2020.
