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

We have a minimum permit required downstream flow requirement of 30 cfs as measured downstream from Randleman Lake Dam, this is maintained on a daily basis. Reductions in the flow requirement are allowed under certain drought conditions.

PTRWA is authorized to transfer 30.5 MGD out of the Deep River Basin to the Haw and Yadkin River Basins. The water that is sold to Greensboro is transferred to the Haw River Basin (28.5 MGD ultimate transfer allocation) and a portion of the water delivered to High Point may be transferred to the Yadkin River Basin (2.0 MGD ultimate transfer allocation).

Did average daily water production exceed 90% of approved plant capacity for five consecutive days during 2022?  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

PTRWA is solely a water wholesaler and 100% of our production capacity is allocated to our partners on a daily basis, we do not typically experience peak demands given the structure of our water contract.

How many sewer connections does this system have?   0
How many water service connections with septic systems does this system have?   0
Are there plans to build or expand wastewater treatment facilities in the next 10 years?   Yes

Wastewater discharge is solely for process water from the water treatment facility and sludge dewatering operations, there is no domestic component. PTRWA is in currently in the 30 percent design stage for a water treatment plant expansion that will also most likely include the addition of treatment to address emerging contaminants. It is expected that this expansion and emerging contaminant treatment project will necessitate expansion and improvements in the wastewater treatment process. Final design for the expansion and emerging contaminant treatment project is expected to be completed by the middle of 2024 with construction beginning at that time.

PTRWA does not directly serve any customers, all water produced is sold directly to other public water systems who deliver water to the end users, the water systems PTRWA provides water to report population and water use projections in their water supply plans. Any expansions to the PTRWA water systems will be as a result of requests from the systems served for additional water up to their contractually allocated allocations. PTRWA anticipates future WTP expansions up to a 48 MGD finished water capacity, with the timing to be based upon the demands in the member's water systems. Above estimates for our system's process water and unaccounted for water take expansions into account. The next expansion is currently predicted to break ground in 2024 with completion slated for 2026, design for the expansion is currently underway.

PTRWA is in the process of planning for an expansion to the existing surface water treatment plant to and expected finished water capacity of 26.7 MGD. Engineering planning and preparation of a Basis of Design Report are to be completed by June of 2023 and final design for the expansion will begin immediately upon completion. It is expected that construction on the expansion will begin in 2024 and that it will be completed in 2026.

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 unavailable until we receive population data for 2022 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.    As our only customers are solely other public water systems we do not plan to implement any plans to reduce future water supply needs, plans for demand management would need to be implemented by the systems that we provide water to.

Are there other demand management practices you will implement to reduce your future supply needs?   As our only customers are solely other public water systems we do not plan to implement any plans to reduce future water supply needs, plans for demand management would need to be implemented by the systems that we provide water to.

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   None.

How does the water system intend to implement the demand management and supply planning components above?   N/A

Additional Information

Has this system participated in regional water supply or water use planning?  Yes, PTRWA is comprised of 6 local governments and was formed to assist these localities in meeting their water supply needs for at least the next 50 years, therefore; by definition PTRWA is a regional water supply and was formed as a result of a regional planning effort.

What major water supply reports or studies were used for planning?  PTRWA conducted several exhaustive studies during the formation and creation of the dam and water treatment plant including a detailed comprehensive environmental impact statement required as part of the reservoir permitting process.

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:   N/A
