CMP Part 4C. Water Supply <br /> Proposed water distribution system expansion is illustrated on Map 4C-3 ��e� e <br /> - _ . Improvements include water main extensions to serve expansion <br /> areas along the west edge of the Highway 12 system. In addition, a portion of the existing <br /> Highway 12 system is recommended to be increased in size from an 8 inch main to a 12 <br /> inch. This improved trunk main will increase available fire flow capacity during <br /> emergencies. In addition, water availability through the east interconnection will be <br /> improved. Depending on the future location of a new supply well to serve the Highway 12 <br /> system, the increased trunk capacity may also be required to allow adequate transmission <br /> of the increased supply capacity to the water tower. <br /> Long Lake Interconnections <br /> Based on computer modeling, not all of the existing interconnections are needed in the <br /> future. We recommend that the two primary automatic PRV interconnections (Virginia <br /> Avenue cZi Wayzata Boulevard and Brimhall Avenue @Wayzata Boulevard) are <br /> maintained. - - . . . . . . . • . . . :.. . <br /> Brimhall Avenue and Wayzata Boulevard. Two interconnections will provide adequate <br /> fire protection during an emergency. In addition, having these on the east and west sides <br /> of the distribution system provides for more redundancy of service as well. Upgrades to a <br /> 12 inch main along Wayzata Boulevard between Brimhall Avenue and Willow Drive North <br /> will also provide a better hydraulic connection for transmission of water during emergency <br /> events. <br /> WATER SYSTEM EMERGENCY PREPAREDNESS PLAN <br /> Purpose <br /> The Orono Water System Emergency Preparedness Plan is a detailed description of <br /> procedures to follow should disruption to normal water service occur. Water system <br /> emergencies can occur as a result of accidental contamination, mechanical problems, <br /> power failures, drought, and other natural disasters. Disruptions to normal service may <br /> affect the entire water system or only parts of the system. While this plan cannot address <br /> all potential disasters, it is intended to provide City staff with a procedural guideline for <br /> implementation of actions resulting in the restoration of normal water service with a <br /> minimum of disruption, and minimizing any potential health risks. This plan is part of the <br /> City of Orono Emergency Preparedness Plan. <br /> Emergency Telephone Lists <br /> The City maintains a list of telephone numbers for key utility and City personnel, contacts <br /> in adjacent communities which may be affected, and other key local, state and federal <br /> contacts. <br /> Current Water Sources and Service Area <br /> 'As-Built'plans and specifications for both the Navarre and Highway 12 water systems are <br /> located on the City's GIS and Asset Management Systems with hard copies located in the <br /> Public Works Map room at 2700 Kelley Parkway. These plans include service area maps <br /> as well as groundwater source information, individual well logs and pump specifications. <br /> City of Orono Community Management Plan 2020-2040 Part 4C, Page 19 <br />
