A Pressure Management Approach to Decarbonization and Achieving Net Zero Goals | Gregg Semler, CEO and Founder, InPipe Energy

Gregg Semler, CEO and Founder of InPipe Energy will share pilot results from installations of InPipe Energy’s HydroXS at East Bay Municipal Utility District (EBMUD) and several others. The HydroXS is an end to end, digitally enabled product line that converts running water to electricity in existing and new pressurized water pipelines. The HydroXS replicates the functionality of a control valve, but instead of wasting energy it produces a consistent, predictable, and reliable source of renewable energy and revenue leveraging existing water pipeline infrastructure without effecting operations.

11:45 a.m. to 12:15 p.m.
Cooling Tower Conversion to Geothermal Sources Saves Precious Water | Jay Egg – President, Egg Geo, LLC

Cooling – tower = elimination by going geothermal. Cooling towers in commercial buildings are the number two consumer of potable water in buildings in the US. Elimination of freshwater consumption from cooling tower use can be accomplished through geothermal exchange methods.

12:15 PM – 2:00 PM
Lunch and Student Presentations

2:00 PM – 2:30 PM
Emerging Water Contaminants Impact on Premise Plumbing Systems | Bob Bowcock – Integrated Resource Management

An introduction to emerging water contaminants from the Safe Drinking Water Act, Clean Water Act, Comprehensive Environmental Response, Compensation and Liability Act and the Resource Conservation and Recovery Act, and their implication for plumbing designers, installers, building owners and operators.

2:30 PM – 3:00 PM
Yorba Linda Water District Installs Largest Ion Exchange PFAS Removal Water Treatment Plant in the US | Kelsey Hakes-Beckwith – Aqueous Vets

PFAS contamination is currently a national issue for both military and civilian drinking water sites. Granular activated carbon (GAC) and ion exchange (IX) resin treatment have become the most economical solution in removing PFAS compounds from groundwater. The Yorba Linda Water District (YLWD) was one of eleven (11) groundwater producers whose wells had low levels of Perfluorooctanoic acid (PFOA) and Perfluorooctane sulfonic acid (PFOS). This technical session will detail the process YLWD went through to evaluate the best solution for their ste and water quality and OCWD’s role in taking a proactive approach to addressing PFOA and PFOS in the groundwater. This session will conclude with lessons learned throughout the process of building the country’s largest ion exchange treatment plant.

3:00 PM – 3:30 PM
Circular Sanitation – Urine Recycling as a Solution to Decarbonizing Both Cities and Agriculture | John Lansing, Pat Lando – PAE, Recode

PAE Living Building Case study; design recommendations, code requirements, and approval processes for eco-sanitation in a 5-story office building. Circular sanitation is a paradigm shift from the high-carbon, high cost sewer and wastewater treatment approach. This approach can be successfully implemented in regions with high levels of infrastructure development, such as downtown Portland, Oregon and regions with low levels of infrastructure development.

3:30 PM – 4:00 PM

Public Health Protection with an Evolving Plumbing Code | Christopher Radziminski and Phillip White – City of Vancouver

The plumbing code in Vancouver has been responsive to regulatory obligations, infrastructure constraints, housing development, near research and sustainability initiatives. Objectives can conflict and well-meaning regulations can have unintended consequences, so what has been done to keep public health at the forefront? Cities are facing enormous pressures, technology is changing, and research literature is expanding, and consequently building plumbing and mechanical systems are evolving rapidly. A key message from this presentation is that public health protection must be explicitly prioritized in plumbing code changes.

Premise Plumbing Materials and Opportunistic Premise Plumbing Pathogen Growth | Abraham Cullom, PhD – Special Pathogens Laboratory, a Pace® Laboratory 

This presentation delves into the intricate interplay between premise plumbing materials and the growth of opportunistic premise plumbing pathogens (OPPPs) within in-building plumbing systems. The in-building plumbing environment is a complex biological-chemical milieu, where pipe materials’ impact extends beyond their direct effects on water quality. Material effects are mediated through interactions with myriad other features such as water chemistry and microbial ecology, influencing the proliferation of OPPPs. The importance of material interactions in premise plumbing is emphasized, addressing practical considerations for different pipe materials. Insights into how these materials contribute to disinfectant decay, nutrient addition, and their potential role as antimicrobials are explored. Specific attention is given to the antimicrobial activity of copper and its susceptibility to variations in water chemistry. By examining the multifaceted relationships between premise plumbing materials, water chemistry, microbial ecology, and opportunistic pathogen growth, this presentation contributes valuable insights to the field, informing decisions that promote water safety and public health in built environments.
