The management staff and field personnel were thoroughly trained in the awareness and protection of the environment and species. In addition to this, the location is also prone to severe flooding during the normal wet times of the year. The schedule developed for this project was strictly adhered to in order to meet these flood-likely conditions.


The project consisted of constructing a raw water pump station and intake structure on piles located on a canal of St. Johns River, 41,100lf of 42” HDPE parallel raw water pipelines and a 5 mgd treatment facility. Also included in the project was canal and dredging work, the installation of ACTIFLO treatment system, chlorine contact basins, sludge gravity thickeners,  sludge dewatering process, a belt filter press system and polymer system. Lastly, project included the installation of a pig launcher and retrieval station, the construction of a boat dock in a raw water pump station, underground piping from RWPS to treatment facility, the construction of a chemical building, storage tank, wetland work, a pond and a nature walk.
