A.
Key Water Supply Personnel. Key Water Supply personnel can
be contacted by phone or by two-way radio. Manager and Water Superintendent
are responsible for making all necessary contacts in the event of
an emergency.
B.
Notification Of Public. The Manager (backup — Water Superintendent) is responsible for notifying the public of emergency conditions and any special instructions, such as boil orders, which may be necessary. News media phone numbers are listed in Section 700.440 of this Article.
C.
Other Assistance. Manager and Water Superintendent (or designated
representatives) are responsible for contacting other sources of assistance,
including the Department of Natural Resources.
[Ord. No. 266, 6-11-1990]
In the event of a power failure, the operator on duty should
contact Disaster Power and Light to determine the anticipated length
of the outage. If the outage will last more than two (2) hours, the
operator should contact the Water Superintendent and begin to prepare
emergency generator and gasoline-powered high service pump for use.
The Water Superintendent will contact appropriate personnel and will
initiate emergency operation of the water plant. Note that all water
plant control valves must be operated manually during this period.
If it appears that the power failure will continue for a long period
of time, water conservation measures should be installed.
[Ord. No. 266, 6-11-1990]
A.
Source Contamination. Upon receiving report of a spill into
the river, immediately contact the Manager and the Water Superintendent.
Then, proceed as follows:
1.
Try to fill all tanks and reservoirs to capacity before the contamination
reaches the intakes.
2.
Find out all you can about the material spilled, its source, estimated
time of arrival, and treatment methods available to remove the contaminant.
3.
Water Superintendent or Manager should contact the Department of
Natural Resources for assistance.
4.
The intakes should be shut down while the spill passes, if at all
possible. Conservation measures may have to be initiated.
5.
The Manager or Water Superintendent should contact one of the laboratories
for help in monitoring the contaminant.
B.
System Contamination. Should the plant or distribution system
become contaminated, an attempt should be made to isolate the affected
portion of the system. The public must be notified immediately
not to drink the water! The affected portion should be cleaned
and flushed until no traces of contamination remain.
[Ord. No. 266, 6-11-1990]
Detailed drawings of the water treatment facility and the water
distribution system are available in the Water Superintendent's office.
Also available are records of past operational and analytical reports.
[Ord. No. 266, 6-11-1990]
The following procedures are intended as guidelines for utilizing
tank trucks or trailers to provide potable water during drought or
other emergency conditions. The appropriate Department of Natural
Resources regional office should be contacted before a water hauling
operation is begun.
[Ord. No. 266, 6-11-1990]
Tank trucks or trailers to be used for transporting potable
water should be selected with two (2) considerations in mind: the
nature of the truck's normal use, and the degree of difficulty in
cleaning. Commercial milk or potable water tank trucks are preferred.
Trucks designed for the transport of wine, vegetable oil, beer, or
other food stuffs may also be used. Trucks that have been used to
haul petroleum products or other toxic substances are generally not
acceptable and can be used only with the concurrence of the Department
of Natural Resources.
[Ord. No. 266, 6-11-1990]
A.
Water Trucks. Flush tanks thoroughly with potable water
and inspect for particulate matter such as rust and sediment.
B.
Milk Trucks. Scrub tanks with detergent, flush thoroughly
with potable water, and inspect for cleanliness.
C.
The
following cleaning procedures may be employed for tank trucks normally
used for hauling such liquids as apple juice, vinegar, wine, yeast,
liquid sugar, beer, corn syrup, cottonseed oil, peanut oil, margarine
oil, linseed oil, sunflower oil, and soybean oil:
1.
Open the drain and flush with hot, potable water.
2.
Steam with an emulsifying detergent until the tank is clean. If steam
is not available, circulate the detergent at a temperature of one
hundred eighty degrees Fahrenheit (180°F) to two hundred ten degrees
Fahrenheit (210°F), changing the location of the nozzle to keep
the interior continuously wet from top to bottom. Repeat this procedure
until tank is clean.
3.
Rinse the tank thoroughly with hot, potable water, and drain.

All hoses should be stored off the ground and should be properly
capped in storage and transit to prevent contamination. All equipment
should be of an approved type for water supply purposes, and should
be new or obtained from a water supply application. All hoses, pumps,
and other equipment should be flushed and disinfected before use.
|
[Ord. No. 266, 6-11-1990]
Disinfection can be accomplished by filling the clean tank with
potable water containing at least fifty (50) ppm chlorine and allowing
the water to stand for a minimum of twenty-four (24) hours. The table
below indicates the amount of hypochlorite solution (Purex, Clorox,
or other household bleach) required to produce fifty (50) ppm in various
quantities of water. To insure proper mixing, the bleach must be added
slowly as the tank is being filled.

*Assumes household bleach with five percent (5%) available chlorine.

If circumstances preclude the twenty-four (24) hour waiting
period, special instructions for disinfecting the tank with higher
chlorine concentrations for shorter periods of time can be obtained
from the Department of Natural Resources.

[Ord. No. 266, 6-11-1990]
A.
The
source of water must be an approved public water supply. Tanks should
be filled and emptied through an air-gap to prevent backflow and contamination
of the source. Tank inlets or openings should be covered and properly
sealed.
B.
Water
to be transported via tank truck must carry a free chlorine residual
of one (1) ppm at the beginning of each one thousand (1,000) gallons
of water. The bleach should be added during filling to insure uniform
distribution.
[Ord. No. 266, 6-11-1990]
Chlorine residual should be measured frequently to insure that
a minimum 0.1 ppm free chlorine residual is maintained. If time allows,
tank water should be analyzed for bacterial contamination prior to
use.
