Water Treatment Plant Construction Update

Preparing to backfill the 48” pipe

Loading fill and gravel to be compacted on the north side of the clearwell

This week, crews began backfilling the north side of the clearwell and installing the thickener mechanism in the gravity thickener tank. The lower walls were completed for the mechanical dewatering building, and work is now progressing on the suspended slabs. Crews continue to work on the ballasted flocculation walls and suspended slabs. The first concrete pour for the electrical building and chemical building slabs occurred on Thursday.

Over the next two weeks, work will resume on drilling auger cast piles for the finished water pump station (just north of the clearwell), liquid oxygen storage area (near the electrical building), and miscellaneous 30” – 42” piping. Concrete pours will continue for the ballasted flocculation, chemical building and electrical building. Water testing will begin on the solids storage tank. Refer to the current site plan for locations of each structure.
