Water Use vs. Consumption - What a Difference

Bill Hoffman
President, H.W.(Bill) Hoffman & Associates, LLC

Use or withdrawal is the amount of water withdrawn from a surface or groundwater source for beneficial use. Consumption is the amount of
that water which is not returned to the environment through a wastewater facility or recognized discharge point. Water conservation efforts, like onsite graywater and blackwater reuse, reduce consumption and therefore can be at odds with centralized water reuse efforts.

This presentation will review the reality of these conflicting goals.

AWE Western States Scorecards

Liesel Hans
Director of Programs, Alliance for Water Efficiency

The Alliance for Water Efficiency’s 2022 U.S. State Policy Scorecard for Water Efficiency and Sustainability (Scorecard) evaluated and ranked each U.S. state based on its adoption of laws and policies that advance water efficiency, conservation, sustainability, and affordability. With climate change reducing and interrupting water supplies across much of the United States, there is an urgent need to increase investments in water efficiency and conservation, which are typically the fastest and least expensive ways to save water. Water efficiency also helps build resilience to extreme weather events that are increasing in frequency and duration because of climate change. The Scorecard is intended to encourage state action by identifying exemplary laws and policies as well as opportunities for improvement. States can advance water efficiency by providing financial assistance and adopting policies and requirements that help ensure best practices are implemented. State policy and funding influence water use through water agencies, land use authorities, energy companies, developers and builders, businesses, and the general public. As a result, state policy is an important tool to shape our water future. Join this session to learn how the western states fared in this edition of the Scorecard and where we hope see action in the coming years.

Saving Mono Lake Again - The Challenge of Building Environmentally Just Water Resilience from the Bottom Up

Martha Davis
Former Assistant General Manager - Inland Empire Utilities Agency

In our climate-changed world, Mono Lake illustrates the need for bold local actions to protect and restore distant ecosystems that support both wildlife and people.  Too often, drought-driven water shortages are viewed as a trade-off between environmental and human needs.  From my perspective as a former water agency executive and an environmental advocate, we need to build climate-resilient water supplies from the bottom up, integrating water efficiency, rainwater capture and watershed management with more traditional centralized projects to meet both human and environmental needs.

How to Save Water with the Multifamily Water Demand Calculator

Christoph Lohr
Vice President of Strategic Initiatives - IAPMO

In 2018 IAPMO released the Water Demand Calculator (WDC) in Appendix M of the Uniform Plumbing Code. This revolutionary peak flow rate calculator was the first time in almost 80 years that domestic water systems inside the built environment could be sized differently from the Hunter's curve. The Hunter's Curve estimated peak flow rates by assuming every building operated like a sports stadium at half time. At that time, a revolutionary approach, but it was a 20th Century solution and a 21st century solution is needed. IAPMO, partnering with the University of Cincinnati and ASPE worked for almost a decade to create the WDC by collecting real data of how plumbing system "behavior" in residential homes. What was validated was the long-time hypothesis that plumbing fixtures are not used as frequently in homes. The result: smaller piping systems could be used when using the WDC in lieu of the Hunter's curves, with the potential savings increasing exponentially as the number of units increased (e.g. high-rise residential buildings). But there were a number of potential second order effects: lower construction costs as a result of smaller piping, less water usage as less water is stored and displaced, and finally lower energy usage stemming from less heat transfer from smaller piping and smaller pumps. By right-sizing domestic water distribution systems we can have numerous benefits to the environment, saving water, and potentially reduce the carbon footprint of the built environment

PNM Delivering on Water

Cathy Newby
Director of Tribal Government and Customer Engagement - PNM

The focus of this presentation is on PNM transferring over critical water infrastructure from the now decommissioned San Juan Generating Station for the Navajo-Gallup Water Supply Project and the delivery of life-changing municipal drinking water relief to our Navajo tribal communities that continue to face dire water supply scarcity. The San Juan River is viewed by Navajo people as the lifeblood for the land, for spiritual practices, farming and clean water for daily use.  This project celebrates this big step forward towards the much-needed water improvements for Navajo people, their communities and surrounding communities, and Mother Earth. Operating in the arid Southwest, we understand the importance of protecting and managing scarce water resources. The San Juan Generating Station’s water infrastructure that includes a diversion channel and pumping station on the San Juan River where the water is diverted and pumped eight miles up to a large reservoir where water can be stored. The presentation will review the life changing work done through this project and how PNM is taking action to protect the environment and conserve natural resources while building a clean, secure, and sustainable energy future.

Bioremediation and Stormwater

Reese Baker
Owner - The Raincatcher Inc.

International urban environments are a major contributor to the current water crisis. The same impermeable surfaces in cities designed to efficiently move stormwater away from high traffic areas are the same surfaces that prevent groundwater from recharging and moving various pollutants, e.g. petroleum products, microplastics, pesticides/herbicides, heavy metals, E. coli, etc., downstream and away from populated areas. However, Rain Gardens allow for the capture of stormwater and pollutants to infiltrate the ground downstream and seep through plants, soil microbes, and soil fungi.

Water & Planning - The Missing Connection

Mary Ann Dickinson
Founder, Dickinson Associates

Mike Collignon
Executive Director - Green Builder Coalition

The nexus between water and land use is critical to sustainable development, yet the relationship between these two efforts is often tangential at best. This session explores ways to break down the existing siloes between these two inter-dependent endeavors.

Selling Sustainability: Social Media Engagement

Joshua Harmon
Energy and Sustainability Inspector

Social media engagement training would equip participants with the essential skills and knowledge needed to communicate in the dynamic world of social media.  By exploring the successes and growing pains of the ICC’s Membership Councils and other ICC chapters, the participant will gain a deeper understanding of effective communication strategies and techniques to engage audiences, build a stronger online presence, and ultimately identify ways to drive meaningful interactions with the public and other industry partners/program users.

We will discuss existing social media platforms (i.e. Facebook, Instagram, Twitter, LinkedIn, and YouTube) and provide concepts for consolidating printed and traditional media to streamline and maximize staff resources.

Permeable Grid Pavers for Stormwater Detention, Water Quality, and Runoff Reduction

Dustin Glist
Technical Advisor - Airlite Plastics Co.

Onsite Storm Water Management (SWM) is becoming increasingly important and, in many cases, mandatory. Concerns regarding municipal sewer system performance and watershed health have generated numerous requirements and techniques to mitigate the effects of storms at the local or site level. Following an overview of these issues, this course examines (in detail) a high-performance system of permeable plastic paving grids that addresses such issues while meeting the most stringent demands of onsite traffic, aesthetics, and SWM. This examination includes installation techniques, details, and specifications.
