Water Conservation

What type of rate structure is used? Decreasing Block

How much reclaimed water does this system use? 0.2858 MGD For how many connections? 7

Does this system have an interconnection with another system capable of providing water in an emergency? No

Wilson has two water treatment facilities and two water sources which provide redundancy. However, a simple explanation or "no" checked box does not explain our system adequately. None of our neighbors are large enough to supply all our total needs for water, but we do have several interconnections where we can feed our neighbors which are numbered for clarification. None are large enough, but all could be reversed to supply some water to our system in an emergency.
1) US 301 North Upchurch Road PS 12 inch line to (Wilson County SE District to US 301 other side 6 inch). This could also feed Rocky Mount thru Sharpsburg with a booster PS for emergencies. (this was installed in previous drought in 2008) and could be reversed as this area is at the same elevation as Wilson.
2) We are connected to the Town of Elm City thru the same 12 inch line and PS. This could be reversed as they are at a higher elevation if backflow by-passed.
3) We are interconnected to the Nash County system along NC 58 North at the Wilson / Nash County line. (valve currently closed) This would require a booster station which was installed during previous drought to feed Nash County and Rocky Mount. Again, this could be reversed as Nash County is at a higher elevation.
4) We have two interconnection with the SW District of Wilson County, one along Wiggins Mill Road near Springfield Middle School which feeds their Willing Worker Road PS and a 12 inch along NC 42 West at I95. Both can and do also supply the Northeast District of Johnston County with their PS at the Wilson / Johnston County line. This line could also be reversed as they are at a higher elevation as well. There are currently no agreements with any of our neighbors to reverse flow, only to supply them on a regular basis, or in an emergency, or as agreed upon by MOA.

We have a water contract for sales to Wilson County SE and SW Districts. Technically we are a regular supplier of water based on our contract, but because we almost never sale any water except in an extreme emergency or during a large main break we almost consider it an emergency. The use is indicated as Regular to match Wilson County since we have the capability and the contractual obligation to sale when demanded.

Wilson confirms the present sales contract with Elm City has a sales limit of 0.1000 MGD that expires in 2051.

What is this system's off-stream raw water supply storage capacity? 0 Million gallons

Are surface water sources monitored? Yes, Daily

Are you required to maintain minimum flows downstream of its intake or dam? Yes

Does this system anticipate transferring surface water between river basins? Yes

Transfers 1) Potable water to Johnston County North District. Contentnea Creek 10-2 in Neuse Basin to Little River in Neuse Basin 10-1 ). A portion of the district is within the Contentnea watershed and is not transferred.
2) Potable water to the Town of Elm City is a transfer from Contentnea Creek in Neuse Basin 10-2 to Town Creek in Tar Basin 15-1). Elm City land applies their wastewater.
3) A small portion of Wilson County SE district lies within Town Creek in the Tar River Basin 15-1 transferred from 10-2 Contentnea Creek

Releases: Agreement with ACE in Buckhorn Dam Permit to release 7.6,5.3, or 1.4 CFS into Contentnea Creek based on the Buckhorn Lake level. Buckhorn releases water downstream to Wiggins Mill Reservoir. Lake Wilson releases downstream to Toisnot Reservoir on the other side of town. The safe yield for Buckhorn is adjusted for evaporation, 50 year sedimentation (beginning in 1999), for required releases downstream, and for 10% active storage remaining. Otherwise the safe yield is 31.6 MGD

Did average daily water production exceed 80% of approved plant capacity for five consecutive days during 2024? No

If yes, was any water conservation implemented? No

Did average daily water production exceed 90% of approved plant capacity for five consecutive days during 2024? No

If yes, was any water conservation implemented? No

Are peak day demands expected to exceed the water treatment plant capacity in the next 10 years? No

Engineering plans 100% complete to expand Wiggins Mill from 12 to 16 MGD. Due to budgetary constraints, plans are being revised to only upgrade electrical components at this time and not increase capacity.

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. No Changes

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?

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:
