19. Washington State Department of Health Division of Environmental HealthOffice of Drinking Water Public Health - Always Working for a Safer and Healthier Washington Approval Documents  Engineering Project Reports  Infrastructure facilities  Treatment technologies  Water System Planning Documents  Physical capacity evaluation  Water system expansion Growing Cities, Towns, and Communities Every 6 years for > 1000 connections New Planned Developments 19

20. Washington State Department of Health Division of Environmental HealthOffice of Drinking Water Public Health - Always Working for a Safer and Healthier Washington Water System Plans Look At:  System analysis of infrastructure capacity  Source, storage, distribution piping, treatment  Water usage  Recorded from meters  Estimated for new developments  6-year and 20-year growth projections  Legal water limitations  Water conservation  Management and operations  Source vulnerability and protection  Financial status and budget 20

21. Washington State Department of Health Division of Environmental HealthOffice of Drinking Water Public Health - Always Working for a Safer and Healthier Washington Primary Questions for Approvals For new and expanding systems:  How much water does the system have?  How many connections can they serve? Additionally, for cities and towns:  How much water is available to meet future demands? 21

22. Washington State Department of Health Division of Environmental HealthOffice of Drinking Water Public Health - Always Working for a Safer and Healthier Washington Setting a System’s Capacity 22 Notes: ERU = Equivalent Residential Unit. A system-specific unit of measure. Q I is instantaneous withdrawal limitation in gallons per minute. Q A is annual withdrawal limitation in acre-feet per year.

23. Washington State Department of Health Division of Environmental HealthOffice of Drinking Water Public Health - Always Working for a Safer and Healthier Washington Demand Forecasting 23  Projections for 6 and 20 year periods:  Land use  Population growth Demand forecasts are often based on Thurston Regional Planning Council population projections and demographic information  Water demand in ERUs  Water use efficiency measures  Customer conservation  Reclaimed water for irrigation

24. Washington State Department of Health Division of Environmental HealthOffice of Drinking Water Public Health - Always Working for a Safer and Healthier Washington Planning for Growth Capital Improvement Plan and Water Right Acquisition Plan Conservation Measures Current System Capacity Population Growth  Physical capacity is compared with anticipated demand and estimated conservation to determine where the system will fall short of future needs.  Capital Improvements prioritized to meet needs:  New water rights  New storage  New sources  Larger and extended distribution water mains 24

25. Washington State Department of Health Division of Environmental HealthOffice of Drinking Water Public Health - Always Working for a Safer and Healthier Washington Outcome of System Approval 1) Approved Number of Connections Situation Applies:  Less than 500 connections  Primarily residential  Development with definite growth limitation  Water right limit reached within 6-year planning horizon 2) “Unspecified” Number of Connections w/ ERU Limitation Situation Applies:  Greater than 500 connections  Water rights portfolio is enough for at least 6 years of growth 25

26. Washington State Department of Health Division of Environmental HealthOffice of Drinking Water Public Health - Always Working for a Safer and Healthier Washington Issues for Large Systems  Water systems with high growth rates have reached legal and physical capacity limitations  Some publicly-owned systems have drinking water capacity, but are restricted by sewer capacity Jurisdiction 1990- 2000 2000- 2009 Bucoda1.6%0.6% Lacey4.9%2.6% Olympia2.3%0.7% Rainier4.2%1.8% Tenino1.1%0.7% Tumwater2.4%3.1% Yelm9.4%6.1% 26

27. Washington State Department of Health Division of Environmental HealthOffice of Drinking Water Public Health - Always Working for a Safer and Healthier Washington Issues for Small Group A Systems  Small privately owned systems have difficulty sustaining themselves financially  Poor rate structures and low savings  Aging infrastructure  Regulatory obligations with additional costs  Internal conflict between customers often linked to costs  Expanding privately owned systems is difficult:  Limited by water rights  WSP is required, which is expensive 27

28. Washington State Department of Health Division of Environmental HealthOffice of Drinking Water Public Health - Always Working for a Safer and Healthier Washington Research Needs  Opportunities for system consolidation?  Evaluate consolidation possibilities throughout county by reviewing system physical capacity, water rights, proximity to nearby systems, and the potential for peripheral growth.  When funding for consolidation is available the opportunities will already be known.  Water availability by specific locations within county?  Where are there valid water rights?  Are water rights being lost when businesses or farms close? 5-year relinquishment! 28

29. Washington State Department of Health Division of Environmental HealthOffice of Drinking Water Public Health - Always Working for a Safer and Healthier Washington Municipal Water Law: Impact to Water System Growth  King County Court ruling:  Municipal Water Suppliers defined as publically owned systems (45 systems in Thurston)  Major benefits to municipal water suppliers:  Stopped the 5-year water right relinquishment clock  Able to ignore “place of use”  Future State Supreme Court ruling:  Who is a municipal water supplier?  How will the ruling impact growth and will the proliferation of Group B systems and individual wells continue? 29
