Guilford100 %
What was the year-round population served in 2024?   316,082
Has this system acquired another system since last report?   No

The year-round population served is calculated from the City population and the population served in Guilford County. The city population for 2024, estimated by the City Planning Department, is 301,115 (Planning will have the population in May 2025). Population served outside the City in Guilford County was 14,726 (calculated as outside City connection 6,011 x 2.49 = 14,967). 2.49 is the average population per household in Guilford County. So the population served in 2024 was 301,115 + 14,967 = 316,082. The estimated numbers of City population and average population per household in Guilford County have been provided by City Planning Division.

Jamestown purchases water from PTRWA (allocation of 0.775 MGD) via the distribution lines of High Point and Greensboro. Jamestown is obligated to purchase or pay for 0.500 MGD from PTRWA, and this amount is included in the 2.780 MGD (2.28 MGD firm allocation for High Point + 0.5 MGD for Jamestown) sales contract with High Point. Jamestown routes 0.125 MGD through Greensboro, and this amount is included in the 7.9355 MGD sales contract with Greensboro (7.83 MGD + 0.125 MGD). 7.83 MGD is the firm allocation for Greensboro and 0.125 MGD is additional water for Jamestown above the firm allocation or requested amount, whichever is greater.

The Jamestown contract value (0.15 MGD) is the difference between the allocated amount (0.775 MGD) and the sum of the obligated contract amount (0.500 MGD), and water routed through Greensboro (0.125 MGD).

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.    The City of Greensboro is participating yearly in regular water audits as per AWWA software.

Are there other demand management practices you will implement to reduce your future supply needs?   In the process of upgrading master flow meters with better technology and installing zone meters in the distribution system.

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   No other supplies have been planned at this stage.

How does the water system intend to implement the demand management and supply planning components above?   A project is underway at the Mitchell Plant to improve plant output with improved quality. The project includes modification of Flash chambers including improved flocculators, modifications of settling basins by installing plate settlers. A Generator has been installed at the Piedmont Triad Regional Water Authority (PTRWA), City of Burlington, City of High Point, City of Reidsville, City of Winston Salem and Jamestown.

Additional Information

Has this system participated in regional water supply or water use planning?  Yes, The City of Greensboro is participating in a Regional Water Supply Planning through partnership with surrounding utilities and Water Authority. These are Piedmont Triad Regional Water Authority (PTRWA), City of Burlington, City of High Point, City of Reidsville, City of Winston Salem and Jamestown.

What major water supply reports or studies were used for planning?  The study conducted by Black and Veatch (B$V) on "Water Resources Capacity Development Study" for the City of Greensboro in 2020.

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:   A project is underway to install a second Clearwell for filtered water at Townsend Plant. This will allow for the inspection/repair of one of two Clearwells at any time while keeping the plant running.
