AUTHORIZATION TO REQUEST BIDS FOR CHLORINATION UNITS
RECOMMENDATION:
That the Tustin City Council, at its meeting of September 4, 1990, authorize
staff to solicit bids for two portable chlorination units at a total cost of
$30,000, and carry over remaining budgeted funds in the amount of $95,000 to be
used for installation of permanent chlorination equipment in FY 91-92.
BACKGROUND:
As a result of the addition of the new Nitrate Removal Plant, the Tustin Water
Service was required by the State Department of Health Services (DHS) to apply
for a revised water supply permit. Subsequently, DHS issued a new permit,
subject to several provisions. One of the conditions is as follows: "The City
sha11 provide necessary plumbing and electrical facilities at all groundwater
sources to allow for the rapid installation of chlorinators in case of an
emergency."
Additionally, the United States Environmental Protection Agency (USEPA) has
recently been moving toward promulgating regulations which would require
continuous chlorination of all groundwater sources.
Keeping in mind both current and proposed future requirements, staff requested
that funds be budgeted in the amount of $125,000 for the installation of
permanent chlorination facilities in FY 89-90.
During the design phase for the installation of the permanent equipment, it was
discovered that there is a recently adopted provision of the Uniform Fire Code
which requires that scrubbing chambers be installed at any location where
chlorine injection systems are operating. These devices neutralize any chlorine
gas which might escape as a result of a leak. This new requirement resulted
in an unanticipated cost of an additional $35,000 per well site, or $2453000.
Due to the drastically increased cost, staff now recommends that two portable
chlorination units be purchased in order to satisfy immediate DHS requirements;
and that remaining funds be carried over until the next fiscal year while staff
investigates the availability and feasibility of alternate and/or less
expensive chlorination methods and appurtenant safau' nt.
