4. Total Per Capita Demand: The total per capita water demand in the City of Hugo has fluctuated over the last ten years. Over the long term, it shows a slight decreasing trend. This trend is likely due to increased enforcement of lawn watering restrictions and the recent implementation of water reuse projects. 5. Peak Demand Ratio: In the last five years, the City of Hugo's average maximum day to average day ratio was 3.4. The DNR recommends a peak ratio goal of 2.6. The City has implemented, and strictly enforces, an odd/even watering ban during all lawn watering seasons. The goal of the watering ban is to reduce the maximum day to average day demand ratio. The City has also recently implemented several stormwater reuse projects, described below, which are expected to lower the peak ratio. A slight decreasing trend in this ratio has emerged since 2014, which may be attributable to these reuse projects. 6. Rate Structure: The City has implemented a water utility rate structure for all customer categories on a quarterly basis, and the overall rate structure is included in Appendix 9-9. The volume included in the base rate charge for residential customers is 15,000 gallons; however, the City also charges based on the actual usage by the customer (residential, institutional/commercial/industrial, and irrigation). The charges assessed based on the actual water usage is a conservation rate structure, meaning that the rate per unit increases as water use increases. This is also referred to as an IHL 2040 COMPREHENSIVE PLAN UPDATE increasing block rate. The increasing block rate is desirable from a conservation standpoint as it promotes conservation awareness to each individual customer. In addition, the water rates are evaluated on a yearly basis. 7. Additional Strategies: The DNR has identified a number of additional strategies that communities can use to reduce water use and support wellhead protection planning. The City of Hugo plans to continue implementing or begin to implement the following programs: • Prepare a Comprehensive Open Space Plan • Adopt a Water Use Restriction Ordinance • Adopt an Outdoor Lawn Irrigation Ordinance • Implement a Stormwater Management Program • Implement a Water Conservation Outreach Program • Implement a Rebate Program 8. Tracking Success: The City of Hugo will continue to monitor its per capita water use and its ratio of peak to average day demand. Its per capita water use is already within the DNR's recommended target, but its ratio of peak to average day demand is not. The City will continue to monitor this ratio and pursue a decreasing trend toward the peak ratio goal of 2.6. DRAFT Dec14-17 for review only DRAFT Dec14-17 for review only Stormwater Reuse One particular water conservation goal and initiative of the City of Hugo is stormwater reuse, for which the City has already implemented several systems. These systems draw stormwater from storage ponds for irrigation which would otherwise discharge to nearby surface waters. These projects have the benefits of improving the water quality of the City's surface waters by reducing stormwater runoff and reducing the burden on the potable water supply system for irrigation. The existing project sites include the Oneka Ridge Golf Course, Beaver Ponds Park, and Water's Edge development. Together these projects reduce groundwater demand in the City by approximately 80 million gallons per year. Several new reuse systems are already included in the development plans for the coming years, and the City will continue to identify and pursue stormwater reuse opportunities for existing development. The City has a goal of including stormwater reuse systems in all future major development projects. COMPREHENSIVE WATER SUPPLY 219 AND DISTRIBUITION PLAN
