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 62 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?   

Cary & Apex were granted a combined round 3 Allocation from Everett B. Jordan Lake of 32% of the norminal safe yield of the water supply pool (50yr-100 mgd). As noted previously, the projections identified above have been revised from the round 3 application to make a correction for WTP process water use. The Town will pursue additional Lake Allocation so that the demand does not exceed the available supply prior to 2030. See Attachment B - Plan for meeting the 2030 Demand.

Additional Information

Has this system participated in regional water supply or water use planning?  Yes

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:   Ability to meet projected water demands, achieve IBT requirements, and plan for wastewater discharge are all inter-related. In order to appropriately plan for and manage water use, the Cape Fear Hydrologic Model needs to be updated an available for use.
