FILE NUMBER
Direct the City Attorney to prepare and authorize the City Manager and
the Clerk of the Council to execute an agreement with Severn Trent Water
Purification, Inc. for chlorinator power supply upgrades in the amount of
$79,920.
DISCUSSION
The City of Santa Ana utilizes Chlor-Tec sodium hypochlorite generating
units to provide disinfection for our active water production wells. On-
site sodium hypochlorite generators for each well provide a low strength
0.8% solution. A total of 14 generators are currently in operation.
These units were fabricated and installed by Chlor-Tec incorporated in
2002 and have provided safe and reliable disinfection of the city's
drinking water supply.
However, Chlor-Tec was acquired by Severn Trent Water Purification, Inc.
Severn Trent provides parts and service for Chlor-Tec equipment but the
power supplies originally furnished with the City'S Chlor-Tec units are
no longer available. Rebuilt power supplies have been used when
available, but they are becoming increasingly hard to find and are
unreliable. The existing power supplies are failing on a more frequent
basis.
In order to continue reliable operation of the Ch1or-Tec units, the power
supplies must be replaced with new units at all 14 installations. The
cost for this work is $79,920. An alternative would be to replace all
existing Chlor-Tec hypochlorite generation units with new units. The

total cost for this alternative would be over $500,000. Staff therefore
recommends that the power supplies be replaced in order to extend the
useful life of the existing units.
