LONG RANGE WATER SUPPLY PLANNING FORFUTURE SUSTAINABILITY

7

• Dallas’ 1959 Long Range Water Supply Plan was updated in 1975, 1989, 2000, 2005 and 2014

• The 1959 study recommended that Dallas supply water to surrounding cities

• The passage of Senate Bill 1 of the 75th Legislative Session in 1997 changed water supply planning throughout the State

• Regional water planning groups established • Regional and State water plans required every

five years• Local plans to be provided to the Regional

Water Planning Group for consideration in the Regional Water Plan

2014 DALLAS LONG RANGE WATER SUPPLY PLAN

BRIEF HISTORY OF THE DALLASWATER CONSERVATION PROGRAM

• 1980 – 2000: Education and outreach • 2001: Irrigation Ordinance adopted; conservation rate

tier added; Water Conservation Division established• 2002: Public Awareness Campaign• 2005: Five-Year Strategic Plan adopted; proactive

leak detection and repair accelerated• 2006: Mascot DEW joins Conservation• 2010: Five-Year Plan updated• 2012: Irrigation Ordinance amended to include

mandatory twice weekly maximum schedule• 2016: Five-Year Work Plan adopted

WATER CONSERVATION IRRIGATION ORDINANCE

• Mandatory Irrigation Efficiency Scheduling• 2001 - Irrigation prohibited between 10 a.m. and

6 p.m.• 2012 - Maximum Twice Weekly Watering

Schedule• Prohibited Reckless Irrigation Behaviors

• Watering with broken, misaligned or missing heads

• Watering causing excessive runoff • Watering impervious surfaces (sidewalks,

streets, etc.) • Watering during precipitation or freezing

temperatures • Rain/freeze sensors required on all automatic

systems

City of Dallas Water Conservation Today

WHERE DO WE GO MOVING FORWARD• Industrial, Commercial, Institutional Rebate

Program • An effort to help small businesses and

companies defray the cost of new equipment and processes that conserve water

• Residential Irrigation/ Landscape System Incentive Program

• Incentives to Single and/ Multi Family residents that retrofit their existing irrigation systems with water-conserving equipment

• City of Dallas demonstration garden• As part of City re-organization for 2019 Water

Conservation will be consolidated into Office of Environmental Quality and Sustainability

ONE WATER DEFINEDOne Water is an

integrated planning and implementation

approach to managing finite water resources

for long-term resilience and reliability, meeting both community and

ecosystem needs

21

BENEFITS OF A ONE WATER APPROACH

• Greater resilience and reliability;• Opportunities to optimize regional

infrastructure;• Sustainable community development;• New regulatory flexibility or opportunity;• Economic growth opportunity; and• Increased coordination among

agencies/departments

FRAMEWORK OF ONE WATER DALLAS• Regional Systems• Regulatory Oversight• Infrastructure• System Operation• Water Quality Monitoring• Emergency Services• Long Range Planning Needs

25

Actions Taken• Established functional work groups among programs,

provided support structure for programs to continue operations

• Finalizing logistical moves for consolidated work groups • Established work processes to keep water, wastewater

and stormwater revenues separate• Coordinated five year funding and rate projections for

each of the three utilities • Developing scope for Comprehensive Stormwater

System Assessment
