Shelley Executive Director DIVISION OF DRINKING WATER Tim Davis Director September 13, 2022 Clayten Nelson River Heights City 520 South 500 East River Heights, Utah 84321 Subject: Plan Approval, Lower Well Reconstruction & Gaseous Chlorinator Project, Lower Well (WS001) and Lower Well Chlorinator (TP005); River Heights City, System #03019, File #13093 Dear Clayten Nelson: The Division of Drinking Water (the Division) received the plans and specifications for the proposed Lower Well Reconstruction & Gaseous Chlorinator Project from your consultant, Eric Dursteler, P.E. with Forsgren Engineering on August 4, 2022. Written review comments were provided to your consultant on August 11, 2022. The Division received the revised plans and specifications on August 22, 2022. This project has met the conditions for receiving a plan approval. Our understanding of the project is the removal and reconstruction of River Height City’s Lower Well (WS001) facility. The project includes the demolition of the existing facilities, site excavation, grading and preparation, and construction of the well control building. A gas chlorination addition (TP005) will be built for chlorine residual maintenance only. Additional improvements include improvements to the facility telemetry, pump-to-waste, standby generator, and general site safety and security. The plan review of the proposed Lower Well Chlorinator (TP005) has been completed according to the following: 1. The proposed Lower Well Chlorinator is a Regal Model 216 Automatic Switchover gaseous chlorinator with a Regal Smartvalve gas feed regulator. 2. This chlorinator will add chlorine to the water from the Lower Well (WS001). 3. This chlorinator is intended to provide secondary disinfection in the distribution system and to boost chlorine residual of the chlorinated water delivered to River Heights City. 4. The chlorine dose will be adjusted by an automatic flow-paced or manually adjusted for the constant flow from Lower Well (WS001). The targeted dose is 0.5 ppm with a well pump range of 800 to 1,100 gallons per minute (gpm). Clayten Nelson Page 2 of 2 September 13, 2022 We have completed our review of the plans and specifications, stamped, and signed by Eric Dursteler, P.E., dated July 29, 2022, 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 Lower Well Reconstruction & Gaseous Chlorinator Project are hereby approved. This approval pertains to construction only. An Operating Permit must be obtained from the Director before Lower Well Reconstruction & Gaseous Chlorinator Project 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 Cameron Draney, of this office, at (385) 271-7039, or me at (385) 515-1464. Sincerely, Michael Newberry, P.E.
