Pre-Proposal Meeting (8/13/25) Q&A:

Q1: The scope of work mentioned two sites, is ADWR going to allow you to keep North Plains as a permitted facility and if so, does the scope of work include submitting applications for two new permits?

A1: The Town’s desire is to permit a new managed USF while keeping the North Plains site operational as a constructed USF by modifying the current constructed USF permit. However, we do not know if ADWR will allow modification of the current permit to only include the North Plains site or if they will require a second USF permit application to be submitted.

Q2: Are there recharge alternatives that will not work for the Town’s objectives?

A2: The Town knows that the effluent contains PFAS and because of this we do not want use direct injection methods or recharge in close proximity to drinking water wells.

Q3: Would the consultant or Town be responsible for paying application fees?

A3: The Town will pay the required application fees.

Q4: It appears that some engineering may be needed for the section of the facility that runs through the urbanized area. Design is mentioned in the description but not the scope of work, do you plan on the engineering to be completed at a later phase?

A4: Yes, the Town’s intent is to apply for and receive the USF permit prior to performing any engineering design, if needed, for the channel.

Q5: Has the Town been in communication with Yavapai County Flood Control regarding the project?

A5: No, the Town has not been in contact with Yavapai County Flood Control regarding the project.

Q6: What is the desired recharge capacity of the new managed facility?

A6: The Town’s objective is to permit a managed USF that is capable of recharging at least 2,000 ac-ft a year. The North Plains site would remain operational as a separate facility with a recharge capacity that would be in addition to the 2,000 ac-ft a year.

Q7: What are the current discharge capabilities at Mountain Valley Park?

Q7: The wastewater treatment plant is capable of pumping up to 4.3 MGD, however effluent is limited based on our current population to about 2.7 MGD. As additional growth occurs more effluent will be available.
