As noted above, all water main pipe will be installed by directional drilling. No disruption of street pavement will occur using this technique. Some digging is necessary to connect long sections of pipe together, install valves, service connections, and hydrants. Service to homes and businesses along CSAH 14 will be provided. One-inch diameter copper will be extended to the right-of-way line for each residential home. One business, Water works, will receive a 6-inch diameter pipe for future sprinkling in the building. All necessary valves and hydrants will be provided for fire protection and maintenance of the system. Some tree clearing will be necessary to install the mainline pipe and services, but it will be minimal. The directional drilling will also reduce costs associated with dewatering, since the route is adjacent to Centerville Lake and Peltier Lake. Traffic along CSAH 14 can be maintained throughout construction. The proposed extension of water main from Lakeland Hills to The Shores will result in an extremely long (7000', or 1.3 miles) dead-end line. At the far end of the main is a business, WaterWorks Beach Club, that will require necessary fire protection. In order to maintain 1000 gpm fire flow, the pipe diameter needs to increase from the existing 8" to a 10" inside-diameter pipe. PERMITS It will be necessary to obtain a permit from the MDH (Minnesota Department of Health) for the water main extension. A permit is required from Anoka County to install water main within their right-of-way. It may also be necessary to get approvals from the DNR and Rice Creek Watershed for construction near Centerville Lake and Peltier Lake. EASEMENTS Most of the proposed construction will take place within public right-of-way or existing easements. However, service pipes will extend to property lines and require small temporary CSAH 14 Water Main Extension Page 4
