Energizing Utilities to Embrace Demand Energizing Utilities to Embrace Demand Management South Florida Water Management District Water Summit December 4, 2007 Dave Bracciano Tampa Bay Water
Background • Tampa Bay Water is a regional water supply authority established in 1998 by Florida statutes and Interlocal Agreement among: • Pinellas County • Hillsborough County • Pasco County • New Port Richey • Tampa • St. Petersburg
Tampa Bay Water • Mission • To provide our members with reliable supplies of high-quality water to meet the area’s present and future needs in an economically and environmentally sound manner.
Our Role in Conservation • Tampa Bay Water plans and coordinates conservation • Member governments actively implement programs that save water • SWFWMD provides cooperative funding for conservation and reclaimed water projects
Operationally: • Work with members to insure average annual savings goals (MWP) are met. • Develop tools to help members determine conservation programming effectiveness • Provide coordination regarding Partnership • Fund public awareness and research programs • Work with larger private organizations to expand conservation potential
Master Water Plan Goals • Aggressive Conservation & Reserve/Rotational Capacity • Diversified Supply Sources • Limited Additional Groundwater • Increased Drought Proof/Resistant Components • Meets Environmental Permitting Requirements • Least Cost Consistent with Objectives
Instituting Goals • Master Water Plan Adopted December 1995 with conservation goals • Demand Management Plan, 1997 • Demand management program developed in 1998 (based on use of best management practices) • Partnership Agreement with SWFWMD and Members adopted in 1998
Effective at Reducing Demand • Supported by Government & the Public • Affordable and Cost-effective • Equitable • Reduce wastewater flows/discharge • Reduce energy use What to Look for in Conservation?
Best Management Practices Developed Outdoor Programs: • Reclaimed Water for Irrigation • Efficient Irrigation Rebates • Alternate Onsite Irrigation System Rebates • Large Landscape Surveys • Residential Water Use Surveys • Model Ordinances*
Best Management Practices Developed Indoor Programs: • HET Toilets and Urinals Rebates • Non-residential Clotheswasher Rebates • ICI Surveys/Rebates • Pre-rinse Spray valve replacement
Specifically, Where Do Water Conservation Programs Affect Demand? • Reductions in Average Demand • HET Toilet Programs • H-Axis Clothes Washer Programs • ICI Programs (cooling towers!) • Reductions in Peak/Seasonal Demands • Irrigation/Landscape Rebates • Landscape or Irrigation System Ordinance* • Reclaimed Water Service • Water Restrictions/Enforcement
So How Do We Determine Savings? • Compile and prioritize BMPs that could be implemented by members to effectively reduce potable water use by sector. • Report to SWFWMD annually on cost effective ways to conserve water. • Compile and quantify members five year conservation plans-track regional savings associated with on going and completed projects.
$351,500 What are proposed Potable Water Savings? • Saved approximately 26 million gallons per day (mgd) by the end of FY 2006 • Save approximately 38 mgd by the end of FY 2011 • Potable water savings from reclaimed water use accounts for 15 mgd of the 2006 savings
What is a major driver of regional demand? • Estimate up to 35% all use is exterior use in Tampa Bay region • Outdoor uses increase peak demands • Increased use of in-ground irrigation systems in future with increased population • No clear way to determine if usage is efficient once installed
What Non-regulatory Methods Have been Implemented that You Can Use? • Promote wise water use (FYN, Water-wise awards, Green build programs) • Irrigation evaluation programs offered (public and private labs) • Create a linkage between the landscape and irrigation system • Irrigation system rebates • Conserve Florida/AWE
How to Form Regional Conservation Consistency? • Create user discussion groups (CCC) • Use the same methods to track use and savings (WSC-Conserve Florida) • Develop standard programs that reach beyond political boundaries • Create goals that can be implemented
What’s Out of the Government Box? • Standard, transferable contracts • Performance contracting • Connect different private sector initiatives/methods with associations • Public funding for private savings programs- (ex:Capacity buyback) • Work with affected associations directly
What Else is Needed? Specific BMP’s for water efficient growth Conserved water is an alternative water source- FUNDS Direct relationship between utility government and new growth Define what is a reasonable use of water in new development Transform the marketplace Don’t recreate the wheel
