An Assessment of Urban Water Demand Forecasts in California

An Assessment of Urban Water Demand Forecasts in California

Published: August 2020, Pacific Institute

Authors: Sonali Abraham, Sarah Diringer, and Heather Cooley

In California, urban per capita water demand has declined dramatically over the past several decades, driven in part by greater uptake of water-efficient devices. These reductions have important implications for estimating future water demand. However, failure to account for the long-term trend of declining per capita water demand has led to routine overestimation of future water demand. This can lead to unnecessary and costly investment in unneeded infrastructure and new sources of supply, higher costs, and adverse environmental impacts. This report examines the accuracy of long-range water demand forecasts for California’s 10 largest urban water suppliers. It finds that per capita water demand declined for all water suppliers between 2000 and 2015.

Atlanta Green Infrastructure Strategic Action Plan

The City of Atlanta's Green Infrastructure Strategic Action Plan promotes and supports the implementation of green infrastructure throughout the City by all City departments, partners and the private sector. Atlanta describes green infrastructure as a cost-effective way for the City to address localized flooding and water quality concerns from stormwater runoff, while improving the resiliency of watersheds and natural resources in the face of rapid growth and climate change. These types of infrastructure investments also provide significant environmental,
economic and community benefits to City of Atlanta residents. This action plan also supports the Mayor’s goal of becoming a top tier sustainable city.

Tucson Rate Impacts of Increased Water Efficiency

Tucson Examines the Rate Impacts of Increased Water Efficiency and Finds Customer Savings

Authors: Candice Rupprecht, Mary M. Allen, and Peter Mayer

Publication: AWWA Journal, Feature Article

Date: January 3, 2020

"To answer one of the most vexing customer questions in the water industry—Why do you ask me to conserve and then raise my rates?—utilities have recently begun conducting avoided-cost analyses. ... An avoided-cost analysis considers current and historic population and per capita demand as well as a utility’s current budget, disaggregating them into variable and fixed system costs, and foregone infrastructure and supply acquisition projects." This AWWA Journal feature article details Tucson Water's avoided cost analysis finding that the utility's three decades of water conservation saved the community $416 million in avoided system costs.

Water Use Efficiency Data Study

West Basin Municipal Water District Water Use Efficiency Data Study Fiscal Year 2018-2019

West Basin worked with EKI Environment & Water, Inc. to develop this Water Use Efficiency Data Study to provide a plan that articulates guiding principles and strategies for West Basin’s WUE programs and services and facilitate innovation and adaptability given California’s rapidly changing water resources landscape. Through this effort, a series of fifteen recommendations for West Basin’s overall WUE program were developed covering topics such as communication and outreach, customer agency planning and regulatory compliance support, residential WUE programs, and commercial, industrial, and institutional WUE programs.

Step for Establishing a Local Stormwater Program

Steps for Considering and Implementing a Local Stormwater Program

In March 2019, New Jersey enacted legislation authorizing municipalities, counties, and municipal or county wastewater utilities and utility authorities to establish a stormwater utility on a voluntary basis. This New Jersey Future Fact Sheet sets out the key steps for localities considering establishing a stormwater utility.

Regional Stormwater Management

Regional Stormwater Management: Flood Control at Lower Cost

This New Jersey Future Policy Recommendation report makes the case for taking a regional approach for stormwater management. New Jersey Future finds: "Coordinating efforts across a region can be more effective at solving watershed problems than a fragmented approach where the methods used by one town may conflict with those used in another."

Stormwater Utilities: Overview of Fee Structure & Incentives

Stormwater Utilities: Overview of Fee Structure & Incentive Programs

On March 18, 2019, New Jersey became the 41st state to enact legislation, the Clean Stormwater and Flood Reduction Act, authorizing the creation of stormwater utilities by municipalities, counties, municipal or county sewerage or utilities authorities, or through shared services agreements involving two or more municipalities, the latter of which may or may not include the surrounding county. This report from New Jersey Future outlines how stormwater utilities can structure their fees and establish incentive programs for their ratepayers.

Stormwater Utility Case Study

Stormwater Utility Case Study: Lancaster, Pennsylvania 

In 2014, Lancaster, Pennsylvania, adopted an ordinance creating a stormwater utility to keep its separated storm sewers in a state of good repair, address flooding issues, and avoid stiff fine for non-compliance of its CSO permit. This case study by New Jersey Future provides an overview of how the stormwater utility and the fee imposed to fund it were developed and adopted.

Lead in Drinking Water: A Permanent Solution for NJ

Lead in Drinking Water: A Permanent Solution for New Jersey

This report from the Jersey Water Works Lead in Drinking Water Task Force lays out 19 interdependent actions which, as a package, the Task Force expects can virtually eliminate lead in water within 10 years. One key recommended action is the replacement of lead service lines under privately owned property, a localized infrastructure issue. The report recognizes that drinking water utilities are on the front lines and need funding solutions and other tools from state government; many of the recommended actions address this reality.
