MWD's current rate structure became effective in January 2003. In October 2002, PWP entered into a <br />voluntary purchase order contract with MWD, whereby PWP will be able to purchase up to 90% of its "initial <br />base demand" at the "Tier 1" rate. The "initial base demand" is defined as the maximum firm demand (not <br />including water delivered for in -lieu groundwater storage programs) for MWD water experienced since Fiscal <br />Year 1989. PWP estimates its "initial base demand" to be 23,520 acre - feet/year. This means that with the <br />purchase order contract, PWP may currently purchase up to 21,170 acre - feet/year of water at the Tier 1 rate. In <br />the future, "base demand" is defined as either the agency's "initial base demand" or the rolling 10 -year average <br />of firm demands for MWD water, whichever is higher. Any water purchased from MWD in excess of 90% of <br />the "base demand" must be purchased at the higher Tier 2 rate. <br />The following table shows water rates under MWD's current rate structure. This table includes rates <br />effective January 1, 2012, January 1, 2013 and January 1, 2014. The City purchases both treated and untreated <br />water from MWD. <br />Treatment Surcharge $234 $234 $254 $254 $297 297 <br />Treated Full Service $794 $920 $847 $997 $890 $1032 <br />Includes Delta Supply Surcharge of $58 per acre foot. <br />(2) Excludes Delta Supply Surcharge. <br />Source: MWD. <br />The Tier 1 and Tier 2 Water Supply Rates are designed to recover MWD's water supply costs. The Tier <br />2 Supply Rate is designed to reflect MWD's costs of acquiring new supplies. MWD member agencies are <br />charged the Tier 1 or Tier 2 Water Supply Rate for water purchases, as described above. <br />The System Access Rate is intended to recover a portion of the costs associated with the conveyance <br />and distribution system, including capital, operating and maintenance costs. All users (including member <br />agencies and third -party wheeling entities of the MWD system) pay the System Access Rate. <br />The Water Stewardship Rate is charged on a dollar per acre -foot basis to collect revenues to support <br />MWD's financial commitment to conservation, water recycling, groundwater recovery and other water <br />management programs approved by MWD's Board. The Water Stewardship Rate is charged for every acre -foot <br />of water conveyed by MWD. <br />The System Power Rate is charged on a dollar per acre -foot basis to recover the cost of power necessary <br />to pump water from the State Water Project and Colorado River through the conveyance and distribution system <br />for MWD's member agencies. The System Power Rate is charged for all MWD supplies. Entities wheeling <br />water will continue to pay the actual cost of power to convey water on the State Water Project, the Colorado <br />River Aqueduct or the MWD distribution system, whichever is applicable. <br />MWD charges a treatment surcharge on a dollar per acre -foot basis for treated deliveries. The treatment <br />surcharge is set to recover the cost of providing ekte_l =a�e�s ice, including capital and operating cost. <br />26 <br />TABLE 4 <br />MWD WATER RATES <br />(Dollars per Acre -Foot) <br />Rate Category <br />2012 Rates(') 2013 Rates ('' <br />2014 RatesM <br />Tier 1 <br />Tier 2 Tier 1 <br />Tier 2 <br />Tier 1 <br />Tier 2 <br />Supply Rate <br />$164 <br />$290 $140 <br />$290 <br />$148 <br />$ 290 <br />System Access Rate <br />217 <br />21 223 <br />223 <br />243 <br />243 <br />Water Stewardship Rate <br />43 <br />43 41 <br />41 <br />41 <br />41 <br />System Power Rate <br />136 <br />136 189 <br />189 <br />161 <br />161 <br />Untreated Full Service <br />$560 <br />$686 $593 <br />$743 <br />$593 <br />$ 735 <br />Treatment Surcharge $234 $234 $254 $254 $297 297 <br />Treated Full Service $794 $920 $847 $997 $890 $1032 <br />Includes Delta Supply Surcharge of $58 per acre foot. <br />(2) Excludes Delta Supply Surcharge. <br />Source: MWD. <br />The Tier 1 and Tier 2 Water Supply Rates are designed to recover MWD's water supply costs.
