For this to be effective,the difference in block rates should be significant. • Seasonal rate: higher rates in summer to reduce peak demands • Time of Use rates: lower rates for off peak water use • Bill water use in gallons: this allows customers to compare their use to average rates • Individualized goal rates:typically used for industry, business or other large water users to promote water conservation if they keep within agreed upon goals. Excess Use rates: if water use goes above an agreed upon amount this higher rate is charged • Drought surcharge: an extra fee is charged for guaranteed water use during drought • Use water bill to provide comparisons:simple graphics comparing individual use over time or compare individual use to others. • Service charge or base fee that does not include a water volume—a base charge or fee to cover universal city expenses that are not customer dependent and/or to provide minimal water at a lower rate(e.g.,an amount less than the average residential per capita demand for the water supplier for the last 5 years) • Emergency rates-A community may have a separate conservation rate that only goes into effect when the community or governor declares a drought emergency. These higher rates can help to protect the city budgets during times of significantly less water usage. **Conservation Neutral** • Uniform rate:rate per unit used is the same regardless of the volume used • Odd/even day watering—This approach reduces peak demand on a daily basis for system operation, but it does not reduce overall water use. ***Non-Conserving*** • Service charge or base fee with water volume:an amount of water larger than the average residential per capita demand for the water supplier for the last 5 years • Declining block rate:the rate per unit used decreases as water use increases. 38 78
