"P T 14",
X44 soxr�� To the Mayor and Members of the City Council December 3, 1985
Subject: PILOT PLANT STUDY FOR BIOLOGICAL NUTRIENTS REMOVAL
0873
On January 29, 1985, (M&C C-8836) the City Council approved the subject study with
the University of Texas at Arlington (UTA) for an amount not to exceed $114,571. The
following information is a status report on the 10,000 gallon per day wastewater treatment
facility.
UTA has advertised the construction of the pilot plant and only one bid was received.
Inasmuch as the only bid received was considered unreasonably high, the bid was rejected
and the plant construction approach was modified to include separate bidding for equipment
and construction respectively. In order to expedite and coordinate the plant construction,
UTA hired a construction manager and the Water Department staff agreed to assist with
the site preparation, concrete foundation work, trenching, and plant assembly.
Bids for equipment, materials, and contract electrical -work have been taken separately.
With most bids now received, the total estimated engineering and construction cost is
$65,767. This estimate is less than approved project budget estimated construction cost
of $68,000.
The Environmental Protection Agency and the Texas Water Commission have indicated
that nutrient (nitrogen and phosphorus) removal may be required in the near future under
new permits to protect water quality in the upper Trinity River. The subject study will
allow an evaluation of a promising treatment technique which may be economically attractive
to the City.
Pilot plant completion is projected for January, 1986. The 21 month study should begin
immediately following plant completion.
