In 2008 the Tohopekaliga Water Authority (TWA) retained Tetra Tech to evaluate the
condition of Pump Station No. 60 and 97, and to identify appropriate improvements to
address projected flows and reliability issues. Subsequently, TWA authorized Tetra Tech
to provide full design, permitting, bidding, and construction phase services related to the
recommended improvements.
In general, the improvements to Pump Station No. 60 included structural rehabilitation
of the wet well, installation of three (3) new 20 HP submersible pumps, replacement of
the discharge piping, installation of a biofiltration odor control system, new controls, and
a standby power system. Improvements to Pump Station No. 97 included rehabilitation
of two (2) existing circular wet wells, installation of three (3) new 90 HP submersible
pumps, replacement of the discharge piping, a magnetic flow meter, installation of a
biofiltration odor control system, new controls, and a standby power system. Both pump
stations handle significant flows and are located on fairly small sites which presented
some challenges with respect to equipment layout and maintenance of service during
construction. Accordingly, the contract documents included detailed bypass pumping
requirements, limitations on noise emissions during construction, and stringent
requirements with respect to reliability of the bypass pumping systems. The project was
constructed over a 6-month period without any overflows, interruptions in service, or
claims for additional compensation or contract time.
