During the 97th annual conference, AZ Water provides value to our members by offering a three-day program designed to provide professional development, continuing education, and technology transfer to support our vision of “a vibrant Arizona through safe, reliable water.” Garver is excited for the valuable opportunities to meet, present, learn, and network with other water professionals from throughout the region.
Step-by-Step PFAS Compliance Planning for a Water Utility
The United States Environmental Protection Agency (EPA) has proposed a new regulation to control drinking water consumers’ exposure to several per- and polyfluoroalkyl substances (PFAS). Initial results from two quarters of monitoring indicate several Arizona utilities have PFAS that will soon be regulated, and these utilities will need to evaluate compliance. This presentation will provide a systemic planning approach and indicate factors that could impact the decisions a utility needs to undertake for complying with these proposed PFAS regulations.

Past, Present and Future of UV Technology: Evolution of Applicability for Advanced Treatment Systems
First invented in 1901, the mercury arc lamp has only recently been embraced for UV treatment by municipal water and wastewater treatment systems. With industrial advancements, population growth, and increased consumption of synthesized products, the type and concentration of pollutants encountered in water is constantly evolving, leading to a critical need for UV treatment. This presentation will discuss the evolution of UV technology, the latest UV system options available for disinfection systems, and cutting edge research to provide a window into the future of UV technology.

Corrosion Control Through Treatment and Operations
The Lead and Copper Rule Revisions and Improvements (LCRR and LCRI) aim to reduce human exposure to lead from drinking water by promoting removal of lead service lines and corrosion control treatment (CCT). When lead remains present in premise plumbing, CCT may be needed to minimize its release. However, control of nuisance metals, organics, and disinfectant residuals through operations or treatment can decrease lead release. This presentation discusses factors that influence corrosion and steps water systems can take to assess and implement modifications to their CCT strategies.

Developing Lead Service Line Replacement Plans and Programs
Water systems across the United States need to develop lead service line replacement plans (LSLRPs) for compliance with the Lead and Copper Rule Revisions. This presentation discusses the requirements for LSLRPs, and how water systems are approaching LSLR. It will also capture LSLR requirements from the proposed Lead and Copper Rule Improvements.
Simple Tests to Improve Water Treatment and Disinfection
Common disinfection challenges include residual loss and disinfection byproduct formation. This presentation describes simple, cost-effective bench-scale tests, including hold studies and disinfection byproduct formation potential tests, and shows how to apply them to obtain actionable date for improving disinfectant stability and optimizing disinfection byproduct precursor removal.

Trenchless Pipeline Considerations for Water Infrastructure in the Phoenix Metro
Trenchless technologies offer innovative solutions to construct water infrastructure with reduced disruption to the environment and public. This includes installations beneath roads, railways, environmentally sensitive areas, water bodies, structures, urban areas, mountains, and existing utilities. This presentation will discuss Federal, State and local considerations specific to trenchless pipeline construction in metro Phoenix and review what factors are driving trenchless pipeline construction in the Grand Canyon State.

Trenchless Applications for Wastewater Collection and Force Main Pipelines in Public Right-of-Way
Like many communities across the United States, Phoenix and surrounding areas are challenged with aging infrastructure assets including gravity sewers, pumping stations, force mains and other sewer conveyance methods. Additionally, new systems are needed in areas of expanding populations in new areas of development and in established areas where vertical housing construction is driving increases in population density. This presentation will discuss new construction trenchless applications for gravity wastewater collection and force main pipelines located in public right-of-way where workspace may be limited and difficult to access.
