Exhibit A <br /> Statement of Work <br /> WATER ACTIVITY NAME—Rangely Raw Water Irrigation Flow Study/Design <br /> GRANT RECIPIENT—Town of Rangely <br /> FUNDING SOURCE—Yampa/White/Green Ba din Account <br /> INTRODUCTION AND BACKGROUND <br /> The Town of Rangely currently augments its domestic water supply by a raw water irrigation system. <br /> The current system is in excess of 30-years old. It currently provides raw water for irrigation to large <br /> users,including the school district properties, parks,hospital, golf course and other large open spaces. <br /> It is believed that many of the existing components have exceeded their expected service life and may <br /> need replacement. Because of the extent of the current raw water distribution system,it has the <br /> potential to be expanded to serve most if not all of the residential and commercial/industrial parcels <br /> within the service area of the community. The Town's domestic water system, including its water <br /> treatment plant, is also nearing its expected service life and the Town is currently undertaking plans for <br /> the upgrade and/or replacement of the treatment facility. By taking the significant summer irrigation <br /> season demands off the domestic system,the upgrades to the domestic water system will not need to be <br /> nearly as significant. <br /> OBJECTIVES <br /> 1. Determine and quantify the condition and extent of the existing raw water system,including the <br /> river intake, the raw water pumping systems, the distribution system and available storage. <br /> 2. Create a hydraulic model of the existing system. <br /> 3. Prepare a hydraulic model for the buildout of the raw water system to include additional service <br /> areas as well as different service categories. <br /> 4. Complete a Masterplan for a phased buildout of a future raw water irrigation system. <br /> TASKS <br /> TASK 1—DEFINE EXISTING SYSTEM <br /> Description of Task <br /> • Review the components of the existing system. <br /> • Verify sizes and capacities of existing pumps, storage tanks and distribution lines. <br /> • Determine existing condition of all components and the expected remaining service life. <br /> • Create a hydraulic model for the existing system and any future system. <br /> 1 <br />
