  • Long-term water planning: Future-Proof Water & California Proposition 1 Recorded: Mar 24 2015 74 mins
    Laura Tam, SPUR & Manucher Alemi, Department of Water Resources
    More than two-thirds of the Bay Area’s water is imported from outside the region. Today these supplies are regularly threatened by drought, earthquakes, water quality impairments and new regulations on availability and usage — risks that will intensify with future climate change. Meanwhile, our region of 7 million people will add 2 million more by 2040. Do we have the water we need to support our projected population growth? And what are the most sustainable and reliable ways to supply our future water needs?

    SPUR's report Future-Proof Water, presented by Laura Tam, analyzes the Bay Area’s current water supplies and future growth projections, then recommends the best tools for meeting our water needs — both in the near term and through the end of the century.

    The Governor’s California Water Action Plan (CWAP) released in January 2014 is a five-year plan outlining the ten central actions towards a sustainable water management. In January 2015, California Natural Resources Agency, California EPA and Department of Food and Agriculture released the CWAP Implementation Report, which highlights achievements to date and outlines activities for the next four years. Manucher Alemi will provide an overview of the CWAP and the Proposition 1 to achieve sustainable water management along with DWR’s roles, including expanding water conservation and water use efficiency.
  • Conservation Design Best Practices: Rain Water Catchment and Grey Water Systems Recorded: Mar 24 2015 80 mins
    Peter Rumsey, Point Energy Innovations; Bobby Markowitz, Ecological Concerns Inc., Central Coast Wilds
    Onsite water resources including rainwater catchment and greywater can be used to decrease or eliminate net water demand of commercial and residential developments. Integrated design incorporating smart water-efficient landscape design with water re-use systems result in "Closed Loop Design". New practices such as bringing rainwater into the house for domestic, non-potable use and using grey water to irrigate landscapes with native and drought tolerant plants with innovative irrigation techniques, may be the future of development in California and beyond as water resources become more scarce and unreliable.
  • Implementing Water Budget Rate Structures for Conservation Recorded: Mar 24 2015 71 mins
    Ken Baerenklau, UC Riverside & Tim Barr, Western Municipal Water District
    Ken Baerenklau will present the results of a study conducted at UC Riverside that examined the effects of switching from uniform to budget-based rates in the Eastern Municipal Water District of Southern California. The study utilized ten years of monthly water bills for 12,000 customers in EMWD’s service area to calibrate a household water demand model and then estimate the effects of the budget-based rate structure on water demand after controlling for average price level, weather, and income. The rate structure appears to have reduced demand by 10-15% primarily by causing previously inefficient households to become more efficient.

    The second presentation, by Tim Barr, Western’s Deputy Director of Water Resources, will outline the Western Municipal Water District implementation of a water budget-based rate structure for its retail water customers. Western’s unique approach uses real-time, microzone-specific, evapotranspiration data and modified monthly turfgrass coefficients from UC research to calculate accurate landscape water budgets on a daily basis. Western’s finance and water efficiency staff collaborated with rate and horticultural consultants to develop a structure that safeguards the financial integrity of the District, provides each unique customer with the water they need, and sends appropriate pricing signals based on efficient water use with every water service bill. In 2015, Western linked the rate structure and the District’s shortage contingency program in anticipation of reduced water supplies due to statewide drought.
  • Practical Strategies to Implement Water Efficiency Technologies Recorded: Mar 24 2015 80 mins
    Michelle Maddaus, Maddaus Water Management; Marty Laporte, Stanford; Amin Delagah, PG&E Food Service Technology Center
    The Stanford University water conservation project is a collaboration between Stanford and FishNick and it all started at the 2014 Annual PG&E water showcase! The goal of this project is to establish baseline water and energy use for old dishwashers in large kitchens and also to identify operational changes that can easily be implemented to improve efficiency of water and energy use by kitchen staff.

    In our presentation we will review: elements needed for setting up this project, site selection, and analysis of metering and temperature data from the old and new dishwasher and kitchen processes in a large university kitchen. The data collected by FishNick is used to establish the baseline water and energy use for old inefficient equipment. By reviewing the kitchen operations and understanding staff needs and actions, additional kitchen equipment, maintenance, and efficiency improvements will be implemented. Comparing the water and energy use for the baseline conditions with consumption after the new equipment and processes are in place, helps quantify the potential for water and energy savings and a simple payback for equipment costs.
  • Data, Tools, and Predictions for Water Balance Planning and Public Safety Recorded: Mar 24 2015 71 mins
    Dr. Mark Strudley, NOAA National Weather Service
    California Bay Area weather is some of the most difficult to predict across the United States due to microclimates and complex topography, yet the National Weather Service and emergency management agencies seldom are required to issue severe weather-related warnings. When moisture deficit is not on everyone’s minds, California weather is like a soldier’s life: 99% boredom and 1% panic. Infrequent so-called ‘atmospheric river’ events are the primary driver behind flooding-related hazards along the central CA coast and Bay Area, and also play a leading role in our state’s water supply. In contrast, during times of water shortage, the forecasting challenges remain while the continual emergency of drought persists over years. The National Weather Service, as part of NOAA, implements a Hydrology Program at a local level for water-related decision support and teams with other local, regional, and national resource agencies to provide information pertaining to both flooding and drought.

    This presentation will provide an introduction to the National Weather Service: where we’re located, what we do, and how we partner with agencies, the media, and our customer base (local citizens). We’ll also discuss how both flooding and drought are monitored and predicted, and what data and tools are publicly available that may be used as a catalyst for wise green building design that affords hazard resilience. A modicum of discussion on what the future climate portends for Bay Area water balance will also be provided.
  • Buildings and California’s Water-Energy Nexus Recorded: Mar 24 2015 73 mins
    Jeremy Sigmon, U.S. Green Building Council; Adrienne Johnson, Stanford University; Jennifer Rosser, Sierra Business Council
    How actively are California’s green buildings addressing water conservation and management? What can we do to catalyze an even greater focus on the state’s top environmental priority in these buildings? New research reveals insights from 1,300+ LEED-certified buildings in California and offers new approaches to leverage buildings as part of the solution to the current water crisis.

    Sierra Business Council's Water Energy Nexus Study analyzes the potential to increase energy and water savings by improving the operational efficiency of several small to intermediate sized, Sierra foothill water agencies/districts with a focus on minimizing water losses and improving pumping efficiency.
  • The 21st Century Landscape is Here: Water Wise Landscape Alternatives Recorded: Mar 24 2015 88 mins
    Michael Hazinski, East Bay MUD; Eileen Kelly, Dig Your Garden Landscape Design; Jodie Sheffield, Delta Bluegrass
    Eileen Kelly, Dig Your Garden Landscape Design, will discuss a variety of landscape design alternatives to replace or minimize the traditional lawn such as no-mow grasses, hardscape materials (gravel, decomposed granite, natural stone, boulders, mulch, and sculpture), and eco-friendly strategies such as “sheet mulching” to quickly eradicate the lawn.

    For over ten years, East Bay Municipal Utility District has offered rebates for converting ornamental lawn to sustainable landscaping. Hear Michael Hazinski provide a water utility perspective on the trends in consumer acceptance of sustainable landscaping and a comprehensive approach to implementing landscape water conservation incentives.

    Jodie Sheffield, Sod Development Expert from Delta Bluegrass Company will introduce you to their water saving California Native Sod products. The presentation and discussion will focus on: how to choose the right native sod for your project, water wise irrigation management, and how to maintain native sod.
  • The State of the Science of Using Urban Trees for Stormwater Management Recorded: Mar 24 2015 73 mins
    Peter MacDonagh, Kestrel Design Group/University of Minnesota
    Stormwater professionals have been studying stormwater control measures for decades, and foresters have been studying and growing urban trees for centuries. But the practice of combining the two to use trees as a Stormwater Control Measure is in its infancy. Recent results showing water quality benefits for urban tree/soil systems equal to and surpassing that of many traditional bioretention systems will be presented. As research is rapidly discovering ways to enhance performance of bioretention and urban tree/soil systems, this presentation will also highlight some of the most promising new developments, such as, for example, use of various soil amendments to enhance water quality performance, as well as design strategies to maximize stormwater volume and water quality benefits.

  • Water Utility Response to the Drought: A Panel Discussion Recorded: Mar 25 2014 60 mins
    Jullie Oritz, San Francisco; Deborah Elliott, Napa County; Chris Dundon, Contra Costa; Richard Harris, EBMUD; Robyn Navarra
    Many consider the current drought in California the worst since precipitation record keeping began over a hundred years ago. With the federal government declaring 27 California counties as “Natural Disaster Areas”, water districts are in a crisis mode. This panel discussion will include presentations by some of the largest and most progressive water utilities in Northern California: Contra Costa Water District, East Bay Municipal Utility District, Napa County, San Francisco Public Utilities Commission and Zone 7 Water Agency. Each panelist will describe the water supply outlook for their district and outline the key activities they are pursuing to reduce water use.
  • Water Flows Downhill, As It Always Has: A Look at the History of People & Water Recorded: Mar 25 2014 65 mins
    Brian Fagan, UC Santa Barbara
    Humans have been concerned over water and water supplies since agriculture and stock raising began some 10,000 years ago. What do we know about about droughts in the past and how did ancient societies handle them? Brian Fagan, an archaeologist, looks at examples from western North America and describes what we know about medieval droughts in California and their relevance to today’s water concerns. In what ways are we more vulnerable than those who lived through California droughts a thousand years ago? What fundamental differences are there between human relationships with water in the past and today?
  • Opportunities for Joint Water-Energy Efficiency Programs Recorded: Mar 25 2014 87 mins
    Heather Cooley, Pacific Institute; Karen Koppett, Santa Clara; Sam Newman, PG&E; Kari Binley, PG&E; Amin Delagah, PG&E Food
    Coordinating water-energy efficiency efforts provide a significant opportunity to achieve greater savings for both water and energy utilities. In particular, jointly run end-use water and energy efficiency programs have a huge potential to save energy and water at the home and at the supply source. Yet, coordinated programs face a number of challenges. In this panel, we will describe some of these challenges and how to overcome them. Panelists will include a researcher, a water specialist who has worked on the “Watts to Water” program and PG&E program managers for agricultural irrigation, clothes washers, and commercial kitchens.
  • Past, Present and Future of Water Conservation: a Water Utility Panel Recorded: Mar 19 2013 68 mins
    Julie Ortiz, SFPUC; Richard Harris, EBMUD; Bill McDonnell, Metropolitan Water District; Chris Dundon, Contra Costa Water Dist
    This session was conceived as a way to acknowledge the 10th anniversary of the Water Conservation Showcase and will be structured as a panel discussion. The intention of the session is to take a quick look back at the status of water conservation from ten years ago when the first showcase was held, consider some of the most successful conservation efforts that are active today and explore how utilities will address water management in the future. The presentation will focus on current and emerging approaches toward providing water management services and tools to assist water customers in managing their own water use. These tools are applicable to existing customers as well as new development to maximize cost-effective water efficiency benefits.

    The panelists are from four of the most innovative and ambitious water utilities in California: Julie Ortiz of the San Francisco Public Utilities Commission (SFPUC), Richard Harris of the East Bay Municipal Utility District (EBMUD), Bill McDonald of the Metropolitan Water District, and Chris Dundon of the Contra Costa Water District. Each panelist will provide a brief presentation on their perspective of the past, present and future of water conservation. The bulk of the session will be set aside for what promises to be a lively discussion.
  • A Twenty-First Century U.S. Water Policy Recorded: Mar 19 2013 56 mins
    Dr. Juliet Christian-Smith, Senior Research Associate, Pacific Institute
    It is zero hour for a new US water policy! At a time when many countries are adopting new national approaches to water management, the United States still has no cohesive federal policy, and water-related authorities are dispersed across more than 30 agencies. Here, at last, is a vision for what we as a nation need to do to manage our most vital resource. In this book, leading thinkers at world-class water research institution the Pacific Institute present clear and readable analysis and recommendations for a new federal water policy to confront our national and global challenges at a critical time.

    What exactly is at stake? In the 21st century, pressures on water resources in the United States are growing and conflicts among water users are worsening. Communities continue to struggle to meet water quality standards and to ensure that safe drinking water is available for all. And new challenges are arising as climate change and extreme events worsen, new water quality threats materialize, and financial constraints grow. Yet the United States has not stepped up with adequate leadership to address these problems.

    The inability of national policymakers to safeguard our water makes the United States increasingly vulnerable to serious disruptions of something most of us take for granted: affordable, reliable, and safe water. This book provides an independent assessment of water issues and water management in the United States, addressing emerging and persistent water challenges from the perspectives of science, public policy, environmental justice, economics, and law. With fascinating case studies and first-person accounts of what helps and hinders good water management, this is a clear-eyed look at what we need for a 21st century U.S. water policy.
  • Water Conservation Case Study Session #1: West Coast Innovation Recorded: Mar 19 2013 69 mins
    Jon Gray, Principal & Senior Plumbing Engineer, Interface Engineering & Jeffrey Miller, Miller Company Landscape Architects
    This session will focus on the completed projects of two design firms. These case studies will highlight the innovative solutions that both firms deploy in their efforts to reduce fresh water use and waste-water run-off. The panelists are Lisa Petterson of SERA Architects Inc. and Jeffrey Miller of Miller Company Landscape Architects. The specific projects they will present are described below. Each panelist will share how water conservation measures where achieved in their projects, the measured impact of these solutions and lessons-learned that impacted their future work. The session will end with questions from attendees.

    In 2008, SERA Architects was commissioned to design a high-rise multi-family development to meet the then newly released Living Building Challenge Standard. The team recognized that Net Zero Water would be particularly challenging due to the water needs of a residential building. We applied for a grant to identify regulatory barriers project teams would face when creating Living Buildings. In the undertaking, we found ourselves doing more than just identifying barriers. Ultimately the team’s work resulted in passage of three alternate methods to the state building code and a house bill which legalized the use of rainwater and graywater in Oregon. As a result of these policy changes, the team is celebrating completion of one of the largest rainwater collection projects in Oregon and is now designing what will be one of the largest rainwater-to-potable systems ever built.

    Miller Company Landscape Architects is an award-winning landscape architecture firm located in San Francisco. Case study projects illustrated in this presentation include over 20 green school yards the firm has designed and built in San Francisco. These projects include independent and public schools commissioned by SFUSD, SFPUC and include edible and native gardens, rainwater catchment systems and educational components.
  • Tackling the Nexus: Exemplary Programs that Save Both Energy and Water Recorded: Mar 19 2013 65 mins
    Rachel Young, ACEEE; M. Lorraine White, GEI Consulting; Joe Castro, City of Boulder; Leslie Larocque, McKinstry
    The first portion of the session will be a presentation of the results of a joint ACEEE/AWE Report, Tackling the Nexus: Exemplary Programs that Save Both Energy and Water, which identifies and recognizes the most successful programs that seek both energy and water savings, and chronicles these programs so that others can learn from them. The results of this research include case studies of each award winning programs and an overall synthesis and discussion of the research, including key common characteristics of the best practice programs, recommendations for successful programs, and useful lessons learned. It presents best practice ideas and lessons learned for next-generation customer energy and water efficiency programs, along with concrete examples of successful program implementation. This session will cover the water-energy nexus, the methodology of the report, the winning programs and best practice results and challenges discovered from the research.

    The second portion of the session will be presented by Joe Castro. Joe is one of the winning program administrators and will present on the details of his program, The City of Boulder Colorado's Energy Performance Contracting Program, including the motivation for creating the program, program design, program performance and lessons learned.

    The third portion of the session will be presented by Loraine White. Loraine was an expert panelist and helped determine the winning programs that were included in the report described above. Loraine will speak to the water-energy nexus in greater detail and draw on her years of work in this field and expertise.
  • Power Plants – Curbing the Thirst Recorded: Mar 19 2013 67 mins
    M. Lorraine White, Principal, GEI Consulting
    Generating electricity requires significant quantities of water, primarily for cooling. This demand can be particularly challenging at a local level representing in many cases a community’s single largest consumer. In addition, wastewater from these facilities can have a significant impact on water quality within a region as well. Since 2003, the California Energy Commission evaluated new power plant proposals based on policies that encourage the use of degraded water supplies rather than fresh water by power facilities and where feasible, use zero liquid discharge systems to eliminate wastewater impacts. In addition, efforts to significantly increase the efficiency of water used by power facilities as resulted in significant reductions in overall water demand by new facilities as compared to older plants. This course will explore the water dependencies and efficiency opportunities associated with power plants and the policies that now govern this relationship in California.
  • Art of Stormwater Recorded: Mar 19 2013 45 mins
    Matthew Passmore, Rebar (moderator); Charles Brucker, PLACE Studio; Jennifer Easton, City of San Jose; Linda Wysong, PNCA
    From the beginning, water has been at the center of our lives. We choose to live by it, harness its energy, and certainly depend upon it for sustenance. Historically we collect our stormwater and whisk it away in the most expedient and efficient manner never stopping to consider its ability to make additional contributions. Over the last few decades and with increasing frequency, stormwater has been treated as the important resource it presents. Designers and artists, together with engineers and agencies are looking to celebrate stormwater’s presence in our communities through creative expression, interpretation, and the visible additions of green infrastructure. There are inspiring examples from around the world to motivate us to join efforts with our colleagues and our communities to make an impact and to celebrate water.
