<br />CDM <br /> <br />Section 2 <br />Profile of Existing Water System <br /> <br />. E-mail Distribution List - Residents may sign up to receive regularly distributed <br />e-mails summarizing town Board meetings as well as other pertinent news. <br />Information concerning water conservation and water restrictions has been <br />conveyed to the public through this system. <br /> <br />2.6.5 Parks Department Conservation Efforts <br /> <br />Since 2002, Erie's parks department has gradually adopted a variety of practices that <br />have improved irrigation efficiency on existing parks. This includes the following: <br /> <br />. Improved soil preparation for plantings and grass establishment <br /> <br />. Using a cycle soak method to irrigate turf improving irrigation effectiveness and <br />efficiency <br /> <br />. Planting native vegetation and drought tolerant plants where appropriate <br /> <br />. Irrigating parks in the evenings and at night when evaporation is low <br /> <br />Erie's parks department also meters its irrigation use and is charged by Erie for all <br />water usage. This provides a financial incentive to conserve water. <br /> <br />2.6.6 Use of Reclaimed Water for Irrigation <br /> <br />Erie's non-potable water supply consists of raw water and reclaimed water ("reuse"). <br />The most significant benefit from a water conservation perspective is use of reclaimed <br />water4. Use of reclaimed water reduces the amount of first-use water needed to meet <br />irrigation needs. Colorado water law stipulates the types of water rights that may be <br />recaptured and reused. Erie is legally allowed to reuse its Windy Gap (Table 2-2) <br />return flows5 to exhaustion. This means that Windy Gap water rights may be reused a <br />repeated number of times. Each time a certain amount of water is consumed, the <br />remainder is captured for reuse. Through each cycle the amount of water available for <br />reuse decreases until there is not any water available for reuse, at which point <br />"exhaustion" is reached. All of Erie's remaining water rights are limited to a one-time <br />use. <br /> <br />Erie currently uses non-potable water for irrigation at the Erie Commons and Vista <br />Ridge developments. Since 2002, Erie has reduced its irrigation water needs by <br />reusing an annual average of 210 AFY of reclaimed water on Vista Ridge via <br />exchange. Reclaimed water will also likely be used at Erie Commons in the near <br />future. <br /> <br />4 Reclaimed water is wastewater treated to meet state water quality requirements, which vary <br />depending on the use of the reclaimed water. <br />S Return flows are water that is returned to a surface water body by gravity after use or is <br />discharged from a wastewater treatment plant. <br /> <br />DRAFT <br /> <br />2-13 <br /> <br />\\DENSVR1\PROJECTS\9228 - ERIE\CONSERVATION PLAN\REPORT\DRAFT PRIOR TO PUBLIC REVIEW\CONNIE FORMATTED\SECTION 2.DOC <br />
