IAPMO ANSI Z1324 Benefits and Water Reuse: How IAPMO Product Standards Promote New Technology Use with Wahaso

Local jurisdictions and states have varying rules when it comes to water reuse. Join us for an insightful discussion with Stuart Bailin from Wahaso as we delve into the world of water reuse and purification. Learn about the process of harvesting water from rainwater, groundwater, stormwater condensate, and greywater, and the subsequent cleaning, sanitization, and repurposing for common applications such as site irrigation, cooling tower makeup, boiler makeup, and toilet flushing. 

One of the most significant challenges regulators face is ensuring public health and safety. They are particularly concerned about the systems being deployed in the field, unsure whether they are being built in someone's garage or in a legitimate, technically organized manner. The introduction of third-party standards alleviates the burden on local health departments, sparing them from having to evaluate each individual system. Third-party certification ensures that the equipment has undergone rigorous testing and will produce water that is safe for use.

Legionella in Water: Why the General Services Administration Took Action on Water Quality

29 October 2024

In this episode, we discuss the General Services Administration (GSA) order to address the risk of Legionella and other waterborne pathogens in the water systems of GSA-controlled buildings. The GSA, which owns 1,600 federal buildings and leases space in over 6,500 buildings nationwide, was spurred to action after detecting elevated levels of Legionella bacteria at six GSA-controlled buildings in different regions since 2023. Our guest Dr. Abraham Cullom, a microbiologist with expertise in plumbing systems, talks about the GSA order and the urgent need to stay on top of emerging best water quality practices for plumbing systems to protect building occupants.

Rebuilding Paradise: Lessons in Plumbing Resilience After Catastrophic Wildfire

22 October 2024

In this powerful episode, we delve into the reconstruction journey of Paradise, California following the devastating 2018 Camp Fire that destroyed more than 18,000 structures and killed 85 people. Our guest, Tony Lindsey, Paradise Building Official and Fire Marshal, shares his unique perspective as both a building official and a resident who lost his home in the disaster. Lindsey offers exclusive insights into the challenges faced during evacuation, the complexities of rebuilding a town's water infrastructure, and innovative solutions implemented to ensure clean, safe water for the community. From the installation of backflow devices in every home to the fortification of water storage systems, Lindsey details the town's efforts to create a more resilient Paradise. This episode provides valuable lessons for officials and communities nationwide on preparing for and recovering from catastrophic events.

Pipe Sizing for Storm Drain Performance - Insights from the IAPMO/ASPE White Paper

09 October 2024

Join IAPMO experts Dan Cole and Christoph Lohr for a technical exploration of storm drainage system design and the critical equations engineers need to calculate effect flow rates through piping. Among the key insights is the impact of pipe material on flow velocity. For instance, PVC and cast iron pipes of the same size can have vastly different flow capacities. Dan and Christoph discuss the key differences between the Manning and Darcy-Weisbach equations, why current plumbing code tables may not tell the whole story, and how proposed code changes could give designers more accurate tools for material selection. In an era where storms are increasing causing urban flooding from excessive rainfall events, this episode will help engineers to make informed decisions for accurate storm drainage system sizing and ensure optimal performance and longevity.
