Any rate where the cost per gallon rises as the amount of water used increases, and that can be shown to encourage conservation, can be considered a conservation rate. Conservation rates are based on the premise that the use of water for domestic consumption is fundamental and should be protected. However, as water use increases, it is often for lawn, landscape or other nonessential uses, where opportunities for conservation are greatest. Demand reduction measures must include a conservation rate, as described here, or a uniform rate with a conservation program, as described later in this document. The types of rates mentioned in law are defined as follows: Increasing Block Rates: The cost per gallon increases as water use increases within specified "blocks" or volumes. The increase in cost between each block should be significant enough to encourage conservation. Seasonal Rates: The cost per gallon increases in the summer to encourage the efficient use of water during peak demand periods (caused by outdoor water use). Seasonal rates can take the form of a surcharge added to the normal rate or a separate fee schedule for winter and summer periods. This rate is most effective if water is billed on a monthly basis. Time of Use Rate: Rates are higher at times of the day when water use demands are high. This rate requires specialized meters that can monitor water use during specified segments of time, for instance every 15 minutes. Individualized Goal Rate (Water Budget Rate): A rate with tailored allocations developed for each customer. The rate increases as the allocation is used or exceeded by the customer. The allocation is generally based upon winter or January use. This rate is most effective when water is billed on a monthly basis. Last Updated July 2, 2012 2
