Mantua Town Water System, System #02018, File #19577
Dear Marcus Abel:The Division of Drinking Water (the Division) received the plans and specifications for Tank No. 3 - South Tank from your consultant, Chris Wight, P.E., with Hansen
& Associates, Inc. on February 18, 2025. Written review comments were provided to your consultant on March 6, 2025. The Division received the revised specifications on March 6, 2025.
This project has met the conditions for receiving a plan approval.
Our understanding of the project is the construction of a new partially buried cast-in-place drinking water storage tank. The tank will have a nominal volume of 500,000 gallons, with
an effective storage volume of 450,000 gallons. The new tank will be constructed at the same elevation as the existing 500K Tank (ST002) and will be partially buried. The water level
in the tank will be maintained by the (Old) Well No. 1 (WS003) and (New) Well No. 2 (WS004). Tank No. 3 - South Tank is identified as ST004 in the Division’s database.
We have completed our review of the plans and specifications, stamped and signed byJames B. Flint, P.E., dated February 11, 2025, and find they basically comply with the applicable portions
of Utah’s Administrative Rules for Public Drinking Water Systems in R309. On this basis, the plans for Tank No. 3 - South Tank are hereby approved.
This approval pertains to construction only. An Operating Permit must be obtained from the Director before Tank No. 3 - South Tank may be put in service. A checklist outlining the items
required for operating permit issuance is enclosed for your information.Approvals or permits from the local authority or the county may be necessary before beginning construction of
this project. As the project proceeds, notice of any changes in the approved design, as well as any change affecting the quantity or quality of the delivered water, must be submitted
to the Division. We may also conduct interim and final inspections of this project. Please notify us when actual construction begins so that these inspections can be scheduled.
This approval must be renewed if construction has not begun or if substantial equipment has not been ordered within one year of the date of this letter.
If you have any questions regarding this approval, please contact Hunter Payne, of this office, at [phone], or me at [phone].
