Plans to develop 2 wells every 10 years with anticipated yield of 200 gpm each. Sales Contracts have decreased significantly due to the fact that South Camden WSD has their own water supply and no longer purchases water from Elizabeth City. Demand projections still reflect potential sales to South Camden WSD. Discounting the average daily usage listed in South Camden WSD contract, Elizabeth City's well construction plan may maintain Demand as Percent of Supply at less than 80%.

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.    

Are there other demand management practices you will implement to reduce your future supply needs?   

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   

How does the water system intend to implement the demand management and supply planning components above?   

Sales Contracts have decreased significantly due to the fact that South Camden WSD has their own water supply and no longer purchases water from Elizabeth City. Demand projections still reflect potential sales to South Camden WSD. Discounting the average daily usage listed in South Camden WSD contract, Elizabeth City's well construction plan may maintain Demand as Percent of Supply at less than 80%.

Additional Information

Has this system participated in regional water supply or water use planning?  No

What major water supply reports or studies were used for planning?  

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:   Unaccounted for water usage is one issue that should be addressed. We are in need of metering equipment at each well and upgraded metering equipment and the treatment facility. Also a more comprehensive leak detection program is in need of development. In order to protect the integrity of current raw water suppply, the city will begin developing a Wellhead Protection Program. Also, in order to meet future demand, a redundant raw water supply line from the wellfield to the treatment facility will need to be laid. This will serve a two-fold purpose, one being the age of the exisiting transmission line, the facility would be able to continue receiving the raw supply if it were to fail, and two being the increased future demand will necessitate the need for an additional line to insure an adequate amount of water delivery to the treatment facility. The city has explored the possiblility of developing a deep well system with 2 MGD supply and reverse osmosis treatment. Pilot testing has been completed; however, due to the financial considerations and issues with permitting and discharge location of brine disposal the city has opted to expand the existing shallow wellfield with the addition of approximately 10 additional wells with a projected combined yield of 2 MGD.
