What was the year-round population served in 2025?   11,470
Has this system acquired another system since last report?   No

Smithfield had been reporting its service-area populations as being equal to its WTP capacity of 12,900 on its last five LWSPs (2020 to 2024). This is likely an overestimate. For 2025, the service-area population was estimated at 11,470 by multiplying the number of metered residential connections (4,248) by 2.7, the average number of people per connection as reported on their 2015 to 2019 LWSPs.

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 45 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 changes at this time.

Are there other demand management practices you will implement to reduce your future supply needs?   Our demand will increase slightly I'm sure.

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   I don't think we will grow enough to need additional water. Johnston County is going to build another plant to help meet their needs. We increased our plant a couple of years ago.

How does the water system intend to implement the demand management and supply planning components above?   If Johnston County builds another plant i think they will need less water from Smithfield.

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?  none

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:   With the growth of Smithfield we will have to add another tank in the future.
Our intake on Neuse river has a lot of sand we have had Hazen and Sawyer to design a new intake but not sure when we will install.
Water loss is low but these are the numbers I have.
