What was the year-round population served in 2022?   320,756
Has this system acquired another system since last report?   No

Year round population served is calculated from City population and population served in Guilford County. City population for 2022 as estimated by City Planning Department is 303,787. Population served outside City in Guilford County was 17,038 (calculated as outside City connection 6926 x 2.45 = 16,968.7). 2.45 is the average population per household in Guilford County. So population served in 2022 was 303787+16,969 = 320,756.
The estimated numbers of City population and average population per household in Guilford County have been provided by City Planning Division.

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 52 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 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 Mitchell Plant to improve plant output with improve quality. The project includes modification of Flash mix, Floc chambers including improved flocculators, modification of settling basins by installing plate settlers. A Generator has been installed at Mitchell Plant to ensure uninterrupted power supply.
A project is also underway at Townsend Plant to install a second Generator to ensure uninterrupted power supply.

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 Highpoint, 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 & Veatch (B&V) on "Water Resources Capacity Development Study" for 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 under planning to install a second Clearwell for finished water at Townsend Plant to have flexibility for inspection/repair of any one of two Clearwell any time keeping the plant running.
