What are the estimated total miles of distribution system lines?   1,565 Miles
How many feet of distribution lines were replaced during 2025?   6,678 Feet
How many feet of new water mains were added during 2025?   51,060 Feet
How many meters were replaced in 2025?   5,639
How old are the oldest meters in this system?   25 Year(s)
How many meters for outdoor water use, such as irrigation, are not billed for sewer services?   7,100
What is this system's finished water storage capacity?   31.8000 Million Gallons
Has water pressure been inadequate in any part of the system since last update? Line breaks that were repaired quickly should not be included.   No

The estimated total miles of water lines do not include privately owned water lines (estimated 369 miles).

The City of Greensboro has replaced the majority of the water meters in its system in the past 5 years. There still exist a few old meters in the system but their age is not a fair representation of the meter age distribution. The average age of Greensboro meters is approximately 6 years old.

Programs
Does this system have a program to work or flush hydrants?   Yes, 2 Years or More
Does this system have a valve exercise program?   Yes, 2 Years or More
Does this system have a cross-connection program?   Yes
Does this system have a program to replace meters?   Yes
Does this system have a plumbing retrofit program?   No
Does this system have an active water conservation public education program?   Yes
Does this system have a leak detection program?   Yes

Our current leak detection program is mostly focus on detecting leaks being reported. Greensboro plans to improve the program to make it a more proactive program and integrated into its non-revenue water program. The goal is to use a combination of technology such as DMAs, machine learning based on pipe scoring factors, and satellite leak detection to help target water mains for repair/replacement and reduce real loss.

Water Conservation
What type of rate structure is used?   Decreasing Block, Flat/Fixed, Increasing Block
How much reclaimed water does this system use?   0.0000 MGD   For how many connections?   0

What was the year-round population served in 2025?   330,632
Has this system acquired another system since last report?   No

The year around population served comprises the estimated population of the City of Greensboro and the estimated population outside city limit in Guilford County. The estimated population of Greensboro resulted from projection based on 2010-2024 populations estimates data from the Office of State Budget and Management (OSBM). The estimated population outside city limit is calculated based on the number of water service connections outside city limit and the average number of persons served per water service connection.

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 51 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 conducts a water audit every year and has completed a non-revenue water analysis in which mid-term and long-term non-revenue water (NRW) targets were established.

Are there other demand management practices you will implement to reduce your future supply needs?   The City of Greensboro conducts water supply meter testing on a regular basis to ensure supply flow accuracy. Additionally, the City will be developing DMAs and using leak detection technology to identify real loss areas and reduce non-revenue water.

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

How does the water system intend to implement the demand management and supply planning components above?   Mitchell Water Treatment Plant is undergoing improvements for hydraulic efficiency. The City of Greensboro has a public education program that encourages the public to conserve water.

Additional Information

Has this system participated in regional water supply or water use planning?  Yes, The City of Greensboro is participating in regional water supply planning through partnership with neighboring water systems including the Piedmont Triad Regional Water Authority (PTRWA), City of Burlington, City of High Point, City of Reidsville, and the City of Winston-Salem.

What major water supply reports or studies were used for planning?  The following major studies were used for planning:
- 2025 Safe Yield Study and 2024 Water Master Plan carried out by Hazen and Sawyer.
- 2025 Non-Revenue Water Analysis developed by Cavanaugh.

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:   The City currently has two advanced treatment projects planned for Mitchell WTP and Townsend WTP to address emerging contaminants. It is anticipated that these projects will start construction in 2026 and both projects will install GAC facilities. Mitchell WTP will also start construction on residual management improvements in 2026.
