Regarding the difference between the purchase amount (0.7878 MGD) and the average monthly flow (0.6941 MGD) -- there was an issue with one of the bulk water meters that was identified in 2024. The amount of flow had to be estimated for a few months at the end of the year, which contributed to the discrepancy between the purchased source water amount and the monthly amount consumed by our customers. The issue has been resolved in early 2025.

We have a filed agreement with Johnston County that they will provide adequate water supply for the entire buildout of the subdivision of Flowers. This is reflected by a Future Supply of 0.1200 MGD needed to keep the demand-to-supply ratio below 80% by 2050.

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 55 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 continue to audit all of our purchase water systems, including Flowers Plantation, to identify any water loss.

Are there other demand management practices you will implement to reduce your future supply needs?   Utilize conservation notices when necessary

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   Increase purchased water from Johnston County

How does the water system intend to implement the demand management and supply planning components above?   Internal engineering team is leading water audits. If additional infrastructure work is required, it will be contracted out to a 3rd party.

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:
