Figure 4.1 shows the timing required to construct the surface water system improvements <br />to meet projected water demand. Total capital investment for this alternative is estimated <br />to be $36,500,000. <br />Alternative 2: Ground Water Supply. <br />With this alternative, additional ground water wells, and a ground water treatment facility <br />would be required. Key improvements are as follows: <br />Phase 1 - Construct 9.6 mgd ground water treatment facility. Facility to be on- <br />line by 2019. Estimated Cost: $24,000,000. <br />Phase 2 - Construct Well 9. Well to be on-line by 2019. Estimated Cost: <br />$900,000. <br />Phase 3 - Construct Well 10. Well to be on-line by 2022. Estimated Cost: <br />$900,000. <br />Phase 4 - Construct 2.4 mgd ground water treatment facility expansion. Facility <br />to be on-line by 2026. Estimated Cost: $4,100,000. <br />Phase 5 - Construct Well 11. Well to be on-line by 2026. Estimated Cost: <br />$900,000. <br />Phase 6 - Construct Well 12. Well to be on-line by 2030. Estimated Cost: <br />900,000. <br />Figure 4.2 shows the timing required for construction of the wells and treatment facility <br />improvement to meet project water demand. Total capital investment for this alternative <br />is estimated to be $31,700,000. <br />City of Ramsey, Minnesota — R13.104504 Page 4-7 <br />Comprehensive Water System Study Prepared by Bolton & Menk, Inc. <br />
