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 47 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.    No Change

Are there other demand management practices you will implement to reduce your future supply needs?   While not strictly a demand management approach, ONWASA has implemented a leak detection program in conjunction with AMI in a effort to reduce our unaccounted water loss.

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?    ONWASA continues its discussion with the operators of a local quarry about the potential for capturing discharge from dewatering activities to supply a planned third treatment plant in the northwestern portion of surface water source (dewatering discharge from an adjacent quarry operation) to feed this facility in addition to existing wells. Additionally design of a third water plant has started in the central area of our system.

How does the water system intend to implement the demand management and supply planning components above?   Through funding from ONWASA's existing capital improvement plan and standing contracts with professional services consulting firms who specialize in these types of activities. We are also soliciting federal/state infrastructure grants applicable to this work.

Additional Information

Has this system participated in regional water supply or water use planning?  Yes, Yes, Yes, The three primary potable water providers in Onslow County (ONWASA, the City of Jacksonville and Marine Corps Base Camp Lejeune) form the Onslow Regional Water Resources Group (ORWRG). Through the efforts of its members, the ORWRG has created a network of groundwater monitoring wells to provide data on the capacity and quality of the source water aquifers all three entities use. It is also a vehicle to share information on each system's activities, anticipated demand and future improvements.

What major water supply reports or studies were used for planning?   A Hydro-Stratigraphic Framework Study (completed in 2014) provided a better understanding of the nature and distribution of groundwater resources within Onslow County, and has guided groundwater monitoring well efforts. The firm that prepared that document also advises the ORWRG.

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:   Efforts are underway in three major areas: securing new raw water sources, increasing treatment capacity and improving the existing distribution system so water can be efficiently moved to the areas it is needed. Construction of a third water treatment plant and securing the raw water sources to feed it are the primary water system focus at the present time, and the cost to complete this work (estimated at $150M) will have a major impact on the current capital improvement plan. ONWASA is also working to address sewage treatment capacity issues in our Swansboro and Southeast collection systems, and that puts additional pressure on our CIP funding.
