In the fall of 2003 Walker Diving was contracted by Kinsley Construction of York, PA to install the raw water intakes for York Water’s new pump station. The new pump station had four 24” diameter intake screens located in the Susquehanna River approximately two hundred and fifty feet from shore. First Walker Diving had to drill and blast the bedrock. Walker Diving utilized the services of J-Roys, Inc. for the drilling and blasting work. Secondly Walker Diving excavated the shot rock using a long reach excavator mounted on a barge. While Walker Diving was excavating, Kinsley’s tunnel contractor drilled from the plant to a point approximately one hundred and fifty feet off-shore with a tunnel-boring machine (TBM). When the TBM broke through the rock Walker Diving recovered the unit. This procedure was done twice. Third, Walker Diving fabricated on land the intake piping, rebar and forms for the first of two intake structures. Each structure was approximately thirty two by ten by eight feet. After setting the form assemblies on the bottom, each assembly was pumped with about one hundred yards of concrete. Walker Diving then installed thirty-six inch D.I.P. and four-inch airlines between each structure and the tunnel casings. Walker Diving covered the pipes by pumping one hundred and eighty yards of concrete underwater. Last, Walker Diving backfilled the trench area. This was followed by testing the intakes, which worked flawlessly the first time!
