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

Thank You!
