FROM: David Townsend, Facilities Engineer
Water Department
DATE: November 12, 1996
SUBJECT: PCM-00513: South Holly Electrical Modifications
and SCADA Isolation Equipment
North and South Holly Water Treatment Plant
Backwash Facilities Modification
and Chlorine and Ammonia Rehabilitation
Project Nos. PW77-060770500020 & PW77-060770500030
This office has reviewed your correspondence dated November 1,1996 on the proposed
contract modification (PCM-005B) concerning the four electrical related items for the
South Holly Water Treatment Plant.
Item 1. Upgrade Minipower Panel Enclosure at South Holly Chemical Storage
Area. The Mini-power Panel LB in South Holly Chemical Storage Area was designed to
provide power only for a portion of chemical storage area equipment and other chemical
storage area electrical needs. Panel LA in the Chlorine Building would provide the
reminder. It was determined that all electrical needs for the chemical storage area should
be from one power panel in the storage area. This requires that Panel LB be changed from
a 15 KVA (Transformer) 208 Volt, 3 Phase, 50 Amp., 18 Circuit Mini-power Center to a
30 KVA (Transformer) 208 Volt, 3 Phase, 100 Amp., 24 Circuit Mini-power Center. As
this panel is outdoors, it should be installed in a NEMA 4X stainless steel enclosure. The
plans do not show this and the contract should therefore be modified to reflect this.
Item 2. Add section to South Holly Chlorine Building MCC-1. The plans show
the removal of all existing electric power panels and the installation of new panels in the
South Holly Chlorine Building. The new panels do not show circuit breakers for the
existing building interior bridge crane and exterior bridge crane at the South Holly
Chemical Building. To provide power to the existing bridge cranes, one panel section
with two 15 amp breakers along with two additional spare breakers should be added.
Item 3. Change Electrical Fixtures in Ammoniator Room to Explosion Proof. The
Fire Department inspector has requested that all electrical fixtures in the South Holly
Chemical Building Ammoniator Room be explosion proof. This requires the all light
fixtures (4 each), emergency light fixture (1 each), thermostat (1 each), and smoke
detectors (2 each), be replaced with explosion proof fixtures. The five electrical outlet
receptacles in the Ammoniator Room must be removed or relocated outside the room.

Page 2
Item 4. Miscellaneous Electrical Modifications. The electrical system in the South
Holly Chlorine Building was removed. New electrical wire/conduits to the existing
exterior and interior bridge cranes where left of the plans and had to be added. Also as the
interior bridge crane was fixed in place, the existing exposed electrical wire system was
removed and the bridge crane rewired for safety and allow required fire walls to be
installed. The electrical circuit required for the specified emergency eyewash heat trace
(to prevent freezing) was missing from the plans and had to be added. The plant requested
to that flow switches be installed at the emergency eyewash stations, to provide
emergency notification to SCADA if an eyewash is activated. Work to be done under
PCM-005B is the installation of electrical and instrumentation wiring.
Item 5. Add chlorine and ammonia feedrate signal to SCADA. The contract
installed ammonia and chlorine feed equipment that could be monitored and adjusted
remotely (SCADA). However, no remote monitoring/control system was to be installed
in this contract. Due to TNRCC regulatory requirements, Plant Operations must monitor
and maintain records on chlorine and ammonia feedrates which can be done from the
SCADA control system. The additional work is to provide instrumentation signal from
feed equipment to SCADA.
Item 6. Isolate chlorine and ammonia signals in Chlorine/Ammonia Cor_trol Panel
To allow the of existing instrumentation cable to the SCADA Building for the chlorine
and ammonia feedrate signals, the feedrate analog signals must be isolated from possible
electrical transient charge (surges, static, etc.) that could damage to the feedrate
equipment and damage.
The Water Department agrees with your recommendation that the contractor price
proposal of $35,071.20 for the six items should be accepted as the cost provided is fair
and reasonable. Therefore, this office will recommend to the City Council (and/or the
City Manager's Office), the approval and acceptance of this additional cost in the form of
a change order to be prepared and submitted by you to this office.
For accounting purposes, this PCM will be paid from PW77-060770500030.

Backwash Facilities Modification
and Chlorine and Ammonia Rehabilitation
Project Nos. PW77-060770500020 & PW77-060770500030
This office has reviewed your correspondence dated November 5, 1996, on the proposed
contract modification (PCM-019) concerning the electrical modifications and SCADA
isolation equipment at the North Holly Chlorine Building. These modifications are:
Item 1. Change Ammonia Room Fixtures to Explosion Proof. The Fire Department inspector
has requested that that are electrical fixtures in the North Holly Chemical Building
Ammoniator Room be explosion proof. This requires the all light fixtures (6 each), emergency
light fixture (1 each), thermostat (1 each), and smoke detectors (2 each), be replaced with
explosion proof fixtures. The six electrical outlet receptacles in the Ammoniator Room must
be deleted (5each) or relocated (1 each) outside the room.
Item 2 Add One Emer encu Light In Chlorine BuildingHallway. An emergency light
is required in each room and hallway in case of a power failure (building code & safety issue).
An emergency light for the hallway, «vas not shown on the plans and is required.
Item 3 Delete UPS By-pass Switch in Electrical Room. The plans show that a By-pass
Switch is to be installed for the UPS in the North Holly Electrical Room (to run the local
computer control systems in case of a power failure). The UPS equipment submittal shows
that the UPS has an internal by-pass switch so an external one is not required and therefore
will be deleted.
Item 4 Miscellaneous Electrical Modifications. The electrical circuit required for the
specified emergency eyewash heat trace (to prevent freezing) was missing from the plans and
had to be added. The plant requested to that flow switches be installed at the emergency
eyewash stations, to provide emergency notification to SCADA if an eyewash is activated.
Work to be done is the installation of electrical and instrumentation wiring.

Item 5 Relocate Existing Electrical Power Feed to Sedimentation Basin #3. The
existing electrical power conduit was found to be in conflict with the proposed pipe channel
from the North Holly Chlorine Building to the North Holly Chemical Storage Area. The
existing power feed was removed and a new feed was installed from Panel LB (Power Panel
for Chemical Storage Area).
The Water Department agrees with your recommendation that the contractor price proposal of
$12,258.59 should be accepted as the cost provided is fair and reasonable. Therefore, this
office will recommend to the City Council (and/or the City Manager's Office), the approval
