The preliminary design phase of the proposed sewer line to serve the properties around Lake Carey is nearing completion, members of the Lemon Township and Tunkhannock Township Joint Municipal Sewer Authority learned last Thursday.
Alan Zeigler with the Larson Design Group provided cost estimates for four crossings that would need to take place as the sewer line is put in the ground.
His work looked at the costs of directional drilling, attachment to PennDOT structures, open cuts and over culverts.
The preliminary design plan reveals that the least cost method of construction is horizontal directional drilling and that will be employed solely in a crossing of Lake Carey at Marina Drive, and a crossing at Kern Glen Creek.
In discussion about crossings at Billings Mill Run North and Billings Mill Run South, Larson recommended that open cuts also be employed.
Larson said he would be submitting to the authority by Sept. 21 a cost analysis of Pennsylvania Department of Environmental Protection permit applications for 12 stream crossings for its authorization at its October 4 meeting.
He indicated his goal was to complete the preliminary design and submit required DEP permit and approval applications by Oct. 19.
Authority secretary Rebecca Kilmer said that requests for information specific to housing hookups to the proposed sewer line had been received as of last week by about 220 households and that was encouraging as the project moves forward. The original plan mandated by DEP called for 282 hookups.
