St. Anthony 2040 Comprehensive Plan Chapter 8: Water Supply <br />172 <br /> <br />PROPOSED IMPROVEMENTS <br />The City of St. Anthony’s existing water system will need maintenance <br />and restoration work to satisfy projected demand through 2040. Table 7 <br />lists the proposed maintenance and improvements, along with estimated <br />dates of implementation and costs. In addition, the City’s Capital <br />Improvement Plan for 2016 to 2032 is included in Appendix 4. <br />TABLE 7: PROPOSED IMPROVEMENTS <br />Year Improvement Estimated Cost <br />2017 WTP and Well SCADA Systems $120,000 <br />2018 Well 5 Rehabilitation $100,000 <br />2020 High Service Pump Upgrades and <br />Piping $341,000 <br />2021 <br />Well 3 Casing $37,500 <br />Well 4 Pump Restoration $75,000 <br />2025 Tower Painting $275,000 <br />2028 Well 4 Permanent Generator $275,000 <br />2030 Well 5 Replace Standby Generator $300,000 <br />Proposed Sources and Treatment <br />It is generally recommended that a City’s treatment or production capacity <br />be equal to at least the maximum day demand with the largest well out of <br />service, known as the system’s firm capacity. <br />The City of St. Anthony’s firm capacity is 3.46 MGD. By the year 2040, <br />the maximum day demand is projected to increase to 2.24 MGD, which is <br />well within the existing firm capacity. Additional production capacity <br />should not be required over the lifetime of this plan. The City is planning <br />to rehabilitate Well 5 in 2018. <br />The City just completed the addition of the advanced oxidation process to <br />its water treatment facility, and the overall treatment capacity of the WTP <br />is approximately 5.0 MGD. This capacity easily satisfies the projected <br />maximum day demand. <br />Proposed Storage <br />It is generally recommended that a City’s storage capacity be equal to at <br />least the average day demand. The City’s projected average day demand
