The Contractor placed concrete for the first section of wall for the Storm and Sanitary Chambers at Pump Station #3 on School property. This pump station will pump storm water and sanitary flows over the levee when flood waters prevent normal flows.
The Contractor also placed concrete for Closure #10 abutment slab on the east side of the Structure. Closure 10 is necessary to provide an access road to the school through the levee system. In times of high water, the closure “gap” will be closed with aluminum “stop logs” similar to what was done on the first Bloomsburg levee project. Large footings are required to deal with the hydraulic forces of the flood waters, especially what the Engineers call “uplift forces” which try to overturn the structure.
The Inspection Trench between Sta. 8+50 to 16+00 and from Sta. 16+50 to 24+50 have been excavated and backfilled. The Toe Drain has been constructed from Sta. 8+50 to 16+00 and 16+50 to 24+50. This drain will collect the seepage that develops during extremely high flood events. It will then be diverted to the two pumping stations so it can be pumped over the levee back to the river.
Placement of Select and Random Levee Embankment continues in these areas. These sections of levee are located on the BASD property.
Installation of an eight foot diameter sanitary manhole and 235 LF of 30″ ductile iron sanitary sewer has been completed.
A 4″ water main to the Municipal Authority Treatment Plant is complete. This main had to be relocated to make way for the re-alignment of the 30 inch interceptor sewer which delivers sanitary flows to the treatment plant.
Fusing (combining separate sections of pipe into one continuous length) of a 5″ conduit for a fiber optic line has started. Boring operations for the conduit under the levee are scheduled to start on Monday July 1st. This main fiber optic line for Verizon Communications is being relocated outside the athletic fields and levee system to minimize any impacts on the levee and the new school stadium.
Differing site condition – During the clearing and excavation activities on the east side of Railroad Street the contractor encountered ash and debris. This situation requires testing of the material and then removal from the site to permit placement of levee soils.
