The forcemain would be at a 10 -foot depth. A few clean out manholes would be <br />built for maintenance cleaning of the forcemain. <br />When the residential property connects to the common forcemain they should <br />anticipate a cost of $3,000 to $6,000 to install a grinder pump and abandon their <br />existing septic system. This cost is very site - dependant, which is why it can vary <br />widely. The type of grinder pump will also influence the cost. Generally grinder <br />pumps are very dependable. A typical pump should give about 10 years of <br />service. Pump replacement is generally not a complicated procedure. <br />This type of system is recommended for this Project over the conventional lift <br />station system. Cost estimates reflect the use of the Grinder Pump /Common <br />Forcemain System. <br />C. WATER <br />City water does not exist in the Project area but the area is within the water system <br />service area. The properties are now served with individual wells. Reconstruction of <br />the street would provide the most opportune time to add watermain improvements to <br />the properties in this area. <br />A 12 -inch watermain is proposed from Birch Street, through the Project, around the <br />north end of the lake, to Black Duck Drive. This will provide adequate fire protection <br />for the project area. Fire hydrants would be installed along the entire route. <br />Each buildable lot would have a 1 -inch service stubbed out for the property owner to <br />connect. <br />The section of watermain that passes through the channel area will need to be placed <br />on piles. The soft soils and the filling of the roadway will make the foundation for this <br />pipe very unstable. Piling will ensure a solid foundation for the pipe. <br />Page 9 13849.005 <br />
