Dave BraccianoTampa 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
What to Look for in Conservation?
•Effective at Reducing Demand•Supported by Government & the Public
•Affordable and Cost-effective•Equitable•Reduce wastewater flows/discharge•Reduce energy use
Best Management Practices Developed
• Reclaimed Water for Irrigation
• Efficient Irrigation Rebates
• Alternate Onsite Irrigation System Rebates
• Large Landscape Surveys
• Residential Water Use Surveys
• Model Ordinances*
Outdoor Programs:
Best Management Practices Developed
• HET Toilets and Urinals Rebates
• Non-residential Clotheswasher Rebates
• ICI Surveys/Rebates
• Pre-rinse Spray valve replacement
Indoor Programs:
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.
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
Where Does the Utility Responsibility End?
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
