RECYCLED WATER – A VALUABLE COMMODITY in the WATER SUPPLY PORTFOLIO
Historical Perspective of Recycled WaterWastewater OR A VALUABLE COMMODITY ?Reuse of Water Versus Developing New
Supplies?Investing in Local Community InfrastructureEncouraging Reuse as an Environmental

HISTORICAL PERSPECTIVE of RECYCLED WATER
WASTEWATER EFFLUENT DISPOSAL Streams, Lakes and Ocean OutfallsSeptic Systems in Small Use Situations
FEDERAL CLEAN WATER ACT -1972 Restricts Discharge of Contaminated Waters
STATE of CALIFORNIA PORTER COLOGNE ACT
Established Discharge Limitations – 1969STATE WATER RESOURCES CONTROL
BOARD Formed – 9 REGIONAL BOARDS
WASTEWATER or VALUABLE COMMODITY ?
Waste Discharge Effluent Considered a Liability and Cost Item
Cost of Water Supply Increased Dramatically
IN 1970-1990-2010 TIMEFRAMESSAN DIEGO REGION IMPORTED WATER
COST • 1970 - $ 150 af • 1990 - $ 400 af • 2010 - $ 750 af
Development of Local Water Supplies - URGENT
REUSE OF WATER VERSUS DEVELOPING NEW SUPPLIES?
COST OF NEW IMPORTED SUPPLY – $ 750 af
MWD Forecasts Cost Increases of 10-20 % a YEAR
Cost of DESALINATED Water Supply - $1,600 af
Availability of Groundwater DECREASING Due to Over Drafting of Local Basins
Drought Cycles Recurring – EACH 7-10 YEARS
Environmental Impacts and Habitat Preservation
Limits on Secondary & Tertiary Wastewater Discharges
New Technology for Advanced Treatment Systems

TOOLS IN MSR AND REORGANIZATION PROCESS
Municipal Service Reviews -PLANNING TOOLS
Sphere of Influence ReviewsPotential for Service Agency ReorganizationsAUTHORITY –
GC 56668 (k) – “timely availability of water supplies”
GC 65332.5 – “close coordination between California’s water supply and land use approval agencies”
Urban Water Management Plan developmentGC 56425 (e) (2) & (3) – need, capacity and
adequacy of public facilities and services
DEVELOPING a WATER SUPPLY RELIABILITY POLICY
GC 56300 (a) – “adopt written policies and procedures and exercise its powers pursuant to this part” that “encourages and provides planned, well-ordered, efficient urban development patterns.”
GC 56301 – “make studies and to obtain and furnish information…contribute to the logical and reasonable development of local agencies in each county” and “shape the development of local agencies…to provide for the present and future needs of each county.”
GC 56425 (a) – “enact policies designed to promote the logical and orderly development of areas within the sphere.”
DEVELOPING a WATER SUPPLY RELIABILITY POLICY – con’t
GC 56425 (i) (1) & (2) – the commission shall…: (1)Require existing districts to file written
statements with the commission specifying the functions or classes of services provided by those districts, and;
(2)Establish the nature, location, and extent of any functions or classes of services provided by existing districts.
GC 56824.12 (a) – Proposal by special district to provide new or different function or class of services
GC 56133 (a) & (e) - request and approval by commission to serve via contract to other agency(ies) outside its (agency) jurisdictional boundaries
Exemption for “transfer of nonpotable water” but not for providing service of water delivery
Establishing Policy and/or Guideline for Water Supply Reliability
Sets Intent and Goals of the CommissionAllows Affected Agencies to Provide InputSets Ground Rules for Future Proposals &
StudiesShould Allow for Data and Information
SharingProvides Baseline for MSR and SOI ReviewsSan Diego LAFCO Water Supply and
Reliability Policy Guideline - 2009
DEVELOPING a WATER SUPPLY RELIABILITY POLICY – con’t
Developed after Water Supply WorkshopsDrafted with Input and Approval of Special
Districts Advisory Committee and Regional Water Agencies
Adopted by Commission Unanimously to Guide Future Proposal Reviews
Revised Proposal Applications to Include Water Supply and Recycled Water Availability and Planning Data
Factor to be Utilized in Reviewing Proposals by Staff

DEVELOPING a WATER SUPPLY RELIABILITY PLANFOR RECYCLED WATER
SUMMARYWATER SUPPLY & REUSE ARE CRUCIAL
ISSUESC-K-H ACT REQUIRES LAFCO TO REVIEW
WATER SUPPLY AVAILABILITY AND SERVICES
C-K-H ACT ALLOWS LAFCO TO STUDY WATER SUPPLY ALTERNATIVES FOR EFFICIENCY
RECYCLED WATER IS INCREASINGLY IMPORTANT COMPONENT OF WATER SUPPLY PORTFOLIO
EACH LAFCO SHOULD DEVELOP A WATER SUPPLY & RELIABILITY POLICY OR GUIDELINE
PLAN NOW FOR THE SOON TO BE FUTURE!
