Water Action Plan (WAP): Motivation Developing a Water Action Plan◦ Defining Scope◦ Documentation of Water Use at UCSB

Data Collection

◦ Baseline to Benchmark Selection Methodology

◦ Identifying Key Practices & Trends in Water Conservation◦ Suggesting Future Water Conservation Efforts

Making Recommendations Using CBA and CEA

◦Making Your WAP a Living Successful Document UCSB WAP Template

Overview of Talk

University of California, Office of the President: Mandate UCSB Future Challenges: Campus growth, Increasing water rates,

and Climate change

Water Action Plan (WAP): Motivation

Magnitude of UCSB Role in the Region/Local Watershed Geographic Scope of Water Use Temporal Scope Water Scope

Developing a WAP: Defining Scope

Data Collection: Quantitative and qualitative information on UCSB’s water history (utilities statements, interviews, audits)

Developing a WAP: Documentation of Water Use at UCSB

3-year Baseline (1996/1997-1998/1999) 3-year “Benchmark” (2008/2009-2010/2011)◦ Purpose: to encourage UCSB to strive for further

reductions

Developing a WAP: Baseline to Benchmark

Baseline to Benchmark

% Reduction

Total Potable Water 25%

Potable Water/ WCU 43%

Potable Water/ GSF 52%

Developing a WAP: Identifying Key Trends & Practices in Water Conservation

Attributing potable water use reduction to past campus actions◦ Irrigation: Potable to reclaimed ◦ Industrial: Expansion of chilled water loop◦ Infrastructure Upgrades: Bathroom retrofits

Cost Benefit Analysis

Suggesting Future Water Conservation Efforts

Installation of a RF/NO System to treat waste and storm water for use on landscapes, in toilets, and as water to supplement cooling towers

Potential Scenarios: Off-site system at local wastewater facility, centralized facility on-campus, decentralized filtration systems on-campus

Collaboration between UCSB, Goleta Sanitary District, Goleta Water District

WAP-G Recommendation using CBA

Laying out all the costs and benefits in a way that predicts the economic value of water conservation efforts

Cost Effective Analysis

Suggesting Future Water Conservation Efforts

WAP-G Recommendations Bathroom/ shower retrofits Weather-based Irrigation Controllers Matched Precipitation (MP) Rotators Xeriscaping Design Scheduled Maintenance

Meeting water savings targets using least cost intensive practices

Goal Setting◦Realistic goals that align with future campus

plans (e.g. Long Range Development Plan)Reporting ◦Annual or Bi-annual basis

Collaboration◦Sharing ideas and the document itself with

stakeholders and other universities
