Maximum Day to Average Day Ratio Less than 2.6 reduce peak demands. ➢ Ordinances for lawn watering including time of day, scheduling (along with information on how often to water) and water wasting (runoff) with adequate enforcement and penalties for noncompliance. ➢ Development approvals with criteria that minimize large open turf areas, require organic soil augmentation for new turf areas on sandy soils, and require one or more trees for new construction. ➢ Customer education/conservation tips during summer peak demands a minimum of four times between May and September of each year. ➢ Conservation Water Rate Structure: Increasing block or summer surcharge with 25 -cent minimum increments between blocks or normal rates. Rate Structures - A conservation or conservation neutral rate structure is required that does not include any volume of water in the service or base charge (lifeline exceptions allowed). Monitoring Plan — A monitoring plan approved by DNR that includes monthly water level readings in production wells and/or observation that may be required. Monitoring data must be submitted to DNR once each year or upon request. Sustainability — All impacts and limits on natural resources and other water users must be satisfied. Currently, the City is below the maximum threshold of 10% unaccounted water so our established practices are working appropriately. For benchmark item Residential Gallons Per Capita, the DNR is following the AWWA Research Foundation study that found the average indoor water use in a conserving home is 45.2 GPCD (gallons per capita day). The study also found that the average indoor water use for a non - conserving home is 63.9 GPCD. The DNR requires Cities to be at 75 GPCD. Lino Lakes is currently at 90 GPCD. Our task is to reduce consumption from our current 90 GCPD to 75 GCPD (20 %). 3
