- Nov. 2007
- Mutual need to reduce drought risk
- Economies of scale
- Technical constraints (one more
intake allowed; limited sites)
- Streamline the approval process
- Strength through partnerships
“We learned you have to work together – stop figh7ng wars. If you don’t, you will have other people deciding what happens in your ci7es and towns.”
Wayne Hill, former Chair of GwinneY County, Georgia Commissioners, regional Chamber of Commerce event, Cary, NC, May 13, 2008
The Jordan Lake Partnership What is the Partnership?
- Interlocal effort begun in 2009 to
coordinate planning and further development of the regional water supply to meet future needs
- Local government led ini;a;ve –
demonstrate that local leadership can solve regional water planning challenges
Who are the Partners?
Apex Cary Chatham County Durham Hillsborough Holly Springs Morrisville Orange County OWASA PiYsboro Raleigh Sanford Wake County
- Develop & maintain buy-in from all governing boards
- Develop regional water supply plan
- Submit coordinated Jordan Lake alloca;on requests
to State
- Explore op;ons for addi;onal facili;es to access
Jordan Lake water supply
- Coordinate with upstream & downstream
stakeholders, state agency staff, and environmental groups
Accomplishments
- Consensus approval of preferred regional soluAon
- Coordinated Jordan Lake allocaAon requests
- Phase I InterconnecAons Inventory
- Interconnec;on Improvements
- Chatham - Durham and Cary - Raleigh
- Phase II Interconnec;ons Modeling complete in 2016
- Western Intake facility planning
Cost Sharing
- Each Partner invests in overall Partnership
- Investment in individual projects is op;onal
- Cost share for most projects is not complex
- Costs are based on size of the Partner
- Typically 2-3 levels of costs for a project
- Long term planning on cost share for large projects
- Coordinated Jordan Lake alloca;on requests
- Plan future infrastructure investments
- Western Intake, treatment and transmission
facili@es
- Regional interconnec@ons
- Broaden focus of regional collabora;on
- Emergency response planning
- Water efficiency educa@on
- Water shortage indicators
- Planning for Triangle Water Partnership

The Big Mo’
Western Intake Study
A shared intake will be more efficient and likely to obtain regulatory approval than individual intakes for each Partner Feasibility Study was completed in 2014 Conceptual level study evaluated the feasibility of a shared raw water intake for: Chatham, Durham, PiYsboro, OWASA Study Included: Evalua;on of three (3) alterna;ves: Review of Partnership op;ons Development of a conceptual level perminng and a construc;on schedule for the Preferred Alterna;ve
Wholesale Water Agreements
Jeff Hughes Environmental Finance Center University of North Carolina at Chapel Hill
What Would You Do? A small town purchases wholesale wastewater service from a neighboring community/town. The legacy contract requires the payment of double the large community retail rate. Rates have risen drama;cally and are approaching $150 per month for customers. And the small town has inflow and infiltra;on problems in their sewer system.

Format
– Ques;ons to consider, descrip;ons, example text – Advice for genng inter-local agreements right, avoid pivalls – NOT drat contract – NOT every issue that will come up in every document
What are Issues you Discuss or Put Down in Wri;ng in your Inter-System Agreements?
§ Service area boundaries § Usage limits § Meter maintenance and ownership § Water quality § Capital costs § Resale or capacity § Water pressure § Communica;ons, service interrup;ons § Conserva;on status and measures
… and more.
Begin with Service Areas
Current boundaries Planned future boundaries Unserved areas Annexation Growth Process to change or expand boundaries in the future Extend whose lines to new areas? Service Area Maps
Capital Costs
§ How does the agreement assure that water suppliers receive
adequate payment for use of their capital?
§ How does the agreement address what happens when facili;es
need to be upgraded and expanded?
§ Does the agreement specify
minimum purchase requirements?
Common Methods
§ Rolling capital costs into the commodity charge (with a
minimum?)
§ An upfront capacity fee § A recurring capacity fee linked to reserved capacity or actual
maximum purchase over a year
§ Purchaser assumes a percentage of seller’s debt service § Pass through retail customer impact fees
Examples 1: Capital Costs
“At the occurrence of such capital improvements, should Monroe issue long-term debt to finance, in whole or part, its water and sewer u@lity capital improvement program, Monroe agrees to nego7ate with Union the terms and condi7ons of financing Union's share of the capital improvements to the WWTP, conveyance, and disposal facili7es providing allocated capacity to Union.” (Union – Monroe)
Examples 2: Minimum Purchase Requirements
“Town will bill the County monthly for the actual amount of
water sold and delivered to it at the then applicable rate; provided however, the Town will bill and County will pay for a minimum quan7ty of 500,000 gallons per month regardless
- f whether or not the County actually uses such
quan7ty.” (Chatham - Siler City) “ … the minimum daily volume shall be one million four hundred thousand (1,400,000) gallons per day.” (Halifax – Roanoke)
Determining Who Owns Unused Capacity?
§ All partners? § A seller? § A buyer? § Who shows use of it in 5, 10, 20 years?
Variable Charges
What does the agreement say about how commodity charges are calculated and modified over @me?
– A. No men;on – B. CPI/infla;on index – C. Cost accoun;ng – D. Linked to retail rate increases
Working Together
§ Does the agreement address non-revenue water or excessive
inflow/infiltra;on?
§ Does the agreement allow for varia;ons due to emergencies? § Are there agreed-upon exit clauses and situa;ons?
Using Transfers to Augment Water Supply

Reliability is typically maintained using large volumes
- f infrequently used capacity
50% of capacity used 2 times in 28 years
Using transfers to manage drought: Research Triangle
§ 4 utilities, 9 reservoirs and 2 watersheds: is there spare capacity during drought? § Some transfer agreements exist, usually “take-or-pay” or “mutual aid” § Working on a new approach involving “risk-based” transfer agreements

Closing Thoughts
- Developing new water supplies is becoming more difficult, so
demand management and transfers being considered more
- Transfers have the potential to reduce the storage capacity
required to maintain reliability, and long-term supply costs
- More detailed regional supply modeling will often be
necessary to identify attractive transfer opportunities
- Swings in revenues (demand management) and costs
(transfers) need to managed if new strategies are to take over
