Demand v/s Percent of Supply

The purpose of the above chart is to show a general indication of how the long-term per capita water demand changes over time. The per capita water demand may actually be different than indicated due to seasonal populations and the accuracy of data submitted. Water systems that have calculated long-term per capita water demand based on a methodology that produces different results may submit their information in the notes field.

Your long-term water demand is 42 gallons per capita per day. What demand management practices do you plan to implement to reduce the per capita water demand (i.e. conduct regular water audits, implement a plumbing retrofit program, employ practices such as rainwater harvesting or reclaimed water)? If these practices are covered elsewhere in your plan, indicate where the practices are discussed here.    We are not making any changes at present. However, we are currently engaged in a Long Range Water Resources Plan project that includes an evaluation of our current water efficiency and conservation programs and the development of a new water efficiency and conservation plan.

Are there other demand management practices you will implement to reduce your future supply needs?   1. Durham will continue to implement and expand its robust water conservation/efficiency program, including enforcement of the Alternate Day Watering schedule and conducting Water Use Assessments for residential and small commercial customers.
2. Durham has a contract with Waste Reduction Partners to provide water assessments for our larger industrial, commercial, and institutional customers.
3. Durham will continue to explore expanded leak detection activities that will augment the current data-logging to extract information from electronic meters.
4. City Council and Administration continue to support pricing signals by approving incremental adjustments to the tiered rate structure for single family residential water customers. The City also plans to evaluate alternative rate structures or budget-based rates.
5. A Master Plan for a robust reclaimed water system was completed in 2017 with the long-term goal of off-setting potable water demands.

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   The City will continue to consider the expansion of Lake Michie as a potential future supply.

How does the water system intend to implement the demand management and supply planning components above?   1. The demand management components listed above are already being implemented.
2. The Western Intake Partnership (a subset of the Triangle Water Supply Partnership) completed a feasibility study for the construction of an intake on the western shore of Jordan Lake, a regional water treatment plant to serve the needs of Durham, Chatham County, Pittsboro and others in the vicinity, as well as other infrastructure needed to deliver potable water to these growing communities.
3. The Western Intake Partnership has launched 4 preliminary projects: Raw Water Intake & Transmission Infrastructure; Governance; Environmental Permitting; and Water Treatment Facility.

Additional Information

Has this system participated in regional water supply or water use planning?  Yes, 1. The City of Durham continues to actively engage in regional planning efforts.
2. The City of Durham is a lead agency in the Triangle Water Supply Partnership (TWSP) which evolved from the Jordan Lake Partnership created by 13 local governments and water systems in 2009 to actively plan for secure and sustainable regional water supply.
3. The award-winning Triangle Regional Water Supply Plan is currently being
updated by the TWSP.
4. In addition to TWSP planning activities, the City participates in other planning efforts which include the Triangle Area Water Supply Monitoring Partnership, Jordan Lake One Water, Upper Neuse River Basin Association, and Upper Cape Fear Basin Association.

What major water supply reports or studies were used for planning?  1. Demand Projections in Section 5 are from the City of Durham Water Demand Projections (2023), and are defined as the Baseline Scenario Water Demand Projections. These baseline projections may change slightly as we continue working on our Long Range Water Resources Plan, expected to be completed in calendar year 2025.
2. Several City plans were updated and used as resources for the Triangle Regional Water Supply Plan (TRWSP). Additional documents were prepared in support of the Environmental Assessment (EA) document for the expansion and upgrades to the Brown and Williams Water Treatment Plants.
3. Water Treatment Facility and Water Reclamation Facility Master Plans have been completed.
4. The Teer Quarry PER Update provided information for the local water supply plan as did the Reclaimed Water Master Plan.
5. Durham continues to participate in a number of studies by UNC faculty/graduate students through the Water Resources Research Institute/Urban Water Consortium to evaluate models for transferring water between regional systems to maximize system yields.
6. The Triangle Water Supply Partnership recently updated the interconnection study that was conducted by the Jordan Lake Partnership.

Please describe any other needs or issues regarding your water supply sources, any water system deficiencies or needed improvements (storage, treatment, etc.) or your ability to meet present and future water needs. Include both quantity and quality considerations, as well as financial, technical, managerial, permitting, and compliance issues:   1. The long term needs for Durham can be met by securing access to the current Jordan Lake allocation and by using Teer Quarry as a regular supply.
2. Both Lake Michie and Little River are very protected water sources, but the City is expanding water quality monitoring and adding treatment options.
3. The City continues to invest millions of dollars to renew and rehabilitate the dam structures at the two reservoirs as well as maintain and rehabilitate the treatment facilities and distribution system to ensure compliance with current and future regulations.
4. Durham has invested in 9 interconnections with neighboring systems to ensure the ability to meet customer demand when there are issues within the system.
