Secondary Treatment Improvements. A second, redundant, activated sludge treatment
system similar to the existing treatment system with an average daily capacity of 0.225
MGD, and peak hourly capacity of 0.900 MGD. This system is to be comprised of the
following:
1. A Parkson(TM) Biolac(R) activated sludge aeration basin, or similar.
2. Secondary effluent clarifier system.
3. RAS/WAS pump station.
4. Aeration system, or modification of existing system, required for the second d
aeration basin.
5. Process piping and systems for splitting of influent, flow measurement, and piping
for aeration air, influent, secondary effluent, and RAS/WAS flows. Electrical and Instrumentation Improvements. Facility electrical and instrumentation
improvements shall comprise of the following:

2. Electrical improvements associated with Phase 3 equipment and operational
requirements.
3. Replacement and/or relocation of existing electrical equipment located in the
existing facility's Operation Room.
4. Replacement of existing SCADA system.
5. Identification and replacement, as required, of electrical equipment and/or
equipment installation, not meeting current NFPA 70E, National Electric Code and
NFPA 820, Fire Protection in Wastewater Treatment and Collection Systems. Recycled Water Pipe System Improvements. A gravity flow effluent pipeline from the
facility to the Lower Effluent Storage Pond (LESP). The pipeline alignment shall parallel
the existing effluent pipeline alignment. Combined capacity of the two pipelines shall be
a minimum of 2.0 MGD. Storage Pond Drainage Improvements. Replacement of existing drain system for the
Upper Effluent Storage Pond (UESP) to the existing Area (Return) pump station. The
