This rate <br />should be set to cover the full cost of service. <br />o The third tier should be above the average annual use and should be priced high enough to <br />encourage conservation, as should any higher tiers. For this to be effective, the difference in <br />block rates should be significant. <br />• Seasonal rate: higher rates in summer to reduce peak demands <br />• Time of Use rates: lower rates for off peak water use <br />• Bill water use in gallons: this allows customers to compare their use to average rates <br />37 <br />
