The task order includes engineering inspections of the existing oxidation ditch and filter structures. Final design drawings for four (4) oxidation ditches and four (4) filters. Bid phase, project estimate, and construction administration. Project details include the process of protecting interior walls, rebuilding interior construction joints, 24” Ductile Iron pipe and fittings inside the tank rehabilitations, surface preparations, sealant preparations, and product application specifications for sealing tank, pipe protection, concrete and steel corrosion protection, construction seam/joint crack rehabilitation.
As City Council may recall, the filter structures have approximately 1.2 million gallons flowing through them daily of partially treated effluent. This filtering process applies constant pressure pushing out on the existing seams. Any leaks can constitute a Sanitary Sewer Overflow (SSO), requiring the city to notify the Florida Department of Environmental Protection that can constitute significant fines to the city. The planned rehabilitation projects are part of the ongoing preventative maintenance program.
