The District has engaged an
engineering firm to evaluate and develop a facility plan. The
recommended facility plan for the Lincoln Sanitary District has
been broken into three different phases.
Phase 1 (short term needs):
Of critical importance to the
continued operation of the Lincoln treatment facility is the
replacement of the existing rotating biological contactors. The
existing 4 RBC’s are recommended to be replaced with mechanical
driven RBC’s. Other items in Phase 1 include the following:
replacement of the RBC building superstructure, truss repairs to
the compost building, replacement of the existing pumps in the
Creamery Court Pump Station, replacement of the existing gas
chlorine disinfection facilities with a sodium hypochlorite
system, upgrading the sludge pumping facilities, and replacement
of some components in the solids dewatering system.
Phase II (short term needs):
Various pump station upgrades including the complete replacement
of one station, a possible chemical phosphorous removal system,
and some blower modifications.
Phase III (long term needs):
This phase would include upgrade of the preliminary treatment
facilities, which would include replacement of the existing grit
removal system. Also included in this phase is replacement of
mechanical equipment in the secondary clarifiers, upgrade of the
sludge pumping facilities, upgrade of the gravity thickeners,
and replacement of the belt filter presses. Collection system
pump stations on Transalpine Avenue and Valentine Court would be
completely replaced in this phase.
