<br />~ <br />v' <br /> <br />Water Conservation Planning Sbrvices <br />I <br /> <br /> <br /> <br />worJing closely with Northglenn staff to compile necessary information. An inventory the Cily,j water <br />supplies, water and wastewater systems, water use patterns, and existing conservation measu'res was <br />completed. We also developed a draft program implementation plan including current and plahned <br />water conservation measures as well as estimated water and financial savings and costs. In dctober <br />200$ Hydrosphere was selected by the City of Northglenn to update their 2005 draft plan to col,form to <br />the rw CWCS Guidance Document. This work is currently underway. I <br /> <br /> <br />Eagl~ River Water & Sanitation District: Conservation Master Plan, Retrofit Study, Drought Response <br />Client Contact: Dennis Gelvin, General Manager <br />I <br />: email: dQelvin@erwsd.orQ <br />: phone: (970) 476-7480 <br />I <br />! <br /> <br />The Eagle River Water & Sanitation District (ERWSD) operates water supply and wastewater systems <br />that serve the towns of Vail, Minturn, Avon, and numerous unincorporated areas. Water cons~rvation is <br />a critical component of the ERWSD's water supply planning strategy because late summer and winter <br />peak demands often coincide with periods when instream flows are at their lowest levels. HYd~osphere <br />has provided ongoing water conservation and drought response consulting services to the ER~SD for <br />over' 15 years, including the development of water conservation plans and drought response plans. In <br />1996, Hydrosphere prepared Water Conservation Master Plans for the ERWSD and the Upperl Eagle <br />Regional Water Authority, incorporating revisions needed to meet the requirements of HS 91-11154. <br />Preparation of these plans involved the characterization of historical water uses and use trends, the <br />identification of potential conservation program measures, and the evaluation of program meaSures in <br />term's of their practicality, effectiveness for meeting program goals, and feasibility given institutibnal, <br />financial, and political constraints. The Conservation Master Plan includes strategies for waterlefficient <br />fixtures and appliances, low water-use landscapes, efficient irrigation, industrial and commercial <br />efficiency, indirect potable and nonpotable reuse, leak detection and repair, public education Pfil1ograms, <br />and )Nater rate structures designed to encourage efficiency. <br />I <br />! <br />In 1998, Hydrosphere conducted an evaluation of the feasibility and effectiveness of water conservation <br />mea~ures involving the retrofit of water efficient indoor plumbing fixtures for large water custo~ers for <br />the I;: RWSD. This investigation included the design and management of a survey of water customers <br />with iservice connections of 25 SFE or larger and a, review of their historical water usage trend. A <br />Wat~r Conservation Planning Model, developed by the Northwest Colorado Council of Governrl ents <br />und~r a grant from the CWCS, was used to estimate potential water savings over time and the <br />eco~omic costs and benefits associated with alternative retrofit programs. Survey and historical use <br />data: were used to establish baseline water consumption conditions without implementation of ~ retrofit <br />program. . I <br /> <br />In response to the 2002 drought, Hydrosphere worked closely the ERWSD to provide monitoring of <br />wat~r supply conditions, projections of water availability, and evaluation of drought response m1easures <br />inclu,ding water rate surcharges to discourage waste. This work involved the development of I <br />stre~mflow forecasts needed determine water availability and preparation of educational matenals to <br />encqurage water customers and golf course managers to implement demand reduction measul es and <br />coorainate water diversions so as to reduce impacts on instream flows. <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br />Pag~ 2 <br />I <br />I <br /> <br />
