FROM: Steve Simmons,,Public Works Superintendent
SUBJECT: Update WaterReservoir Improvements,- Project No. 9917
There are nine steel water storage reservoirs in the City's water distribution system with a
combined capacity of 11.05 million gallons. These reservoirs are being inspected and repaired
on a regular basis. Of these nine reservoirs, three are less than six years old (Manor Lane,
Hardin Lane and Country Club _Reservoirs). Of the,remaining six reservoirs, one is 40 years
old (LaCresta Reservoir #2) and five 'are 28 years old (LaCresta,Reservoir #1, Washington
Reservoir #1, Washington-Reservoir #2, Mountain View Reservoir and Paula Lane Reservoir).
The interior and exterior surfaces of the three newer reservoirs:are protected by epoxy based
paints (current industry standard): The life expectancy of an epoxy based coating system is
about 20 years. Cathodic protection systems were also installed at the time of construction to
further protect the interior steel surfaces of the Manor Lane and Hardin Lane Reservoirs
(current industry standard). The remaining seven reservoirs were constructed without cathodic
protection systems. A properly functioning cathodic protection system serves to prevent
damage to a reservoir's interior steel surfaces below the water level even if the coating were to
completely fail in small areas. At an installed cost /of.less than $15,000 per system, this is
cheap added protection for the City's steel reservoirs that have;replacementvaluesof about one
million dollars per one million,gallons of capacity. It is planned that, as each of the City's
older steel reservoirs is re-coated inside, cathodic protection systems,will be installed. The
City's six oldest reservoirs were coated with coal tar inside and enamel paint outside at the
time of construction. This coating system was state of the;art'at that time.. In 1990, it was
discovered that the interior coating of'the oldest of these six..reservoirs (LaCresta Reservoir
#2), had failed after 31 years'of service allowing+structural damage to occur to the center roof
support structure. Repairs were made and the upper third of the interior tank surface re-
coated. These repairs have made it unnecessary to do a complete interior re-coating of this
reservoir at this time.
Last year, the original coal tar interior coating of the City's second oldest steel reservoir (East
Washington Reservoir #1) was removed and re-coated with,epoxy based paint. Total removal
of the coal tar as well as sand blasting is necessary to provide a suitable surface for the new
paint to adhere to Coal tar cannot be overcoated with paint successfully. A cathodic
protection system was installed on this reservoir as well This reservoir's interior coal tar
coating had finally begun to fail after 28 years, but not to the point" of allowing structural
damage to occur; Unfortunately,from a protection standpoint, coal tar is:no longer used as an
interior coating for potable water storage tanks. The reason for this is that fresh coal tar can
potentially leach minute quantities of petroleum type chemicals into water; for a year or two
Changes to State and Federal water quality regulations now require" that drinking water be
monitored and maximum contaminate levels not exceeded for various petroleum based
chemicals, some of which may be found in coal tar.
The reinthning fout, Steel reservoirs which are all Z8HyearS. Old (La Greta Reservoir- #:l,
Washington Reservoir Mountain View Reservoir and Paula Lane Reseryoir) have had no
re-coating:work:performed on them except for some exterior spot painting ,AEOutlined.inahe
Water System '.CIF'; one of these four reservoirs is scheduled for a complete interior re-coating
each year. The exterior• coatings of the City's csii older. reservoirs are Still in fairly gocid
condition. One or two of these(reservoirs will be scheduled for exterior re-coating as well
each year Re-coating the exterior of these tanks, while the existing coating is still largely
intact, makes it possible to encapsulate Oaint over) the reservoir surface without complete
removal of the Old paint. the old-paint containS,lead and WoUld be very costly to remove due
to the recent enactment of-Strict:le:ad.containrhea regulations.
After discussions with. Tom. Hargis, Director of Engineering;, and .Mike Evert, Supervising.
Engineer, the structural evaluation of all City reservoirs will be done as part of the anticipated.
1997 Water Master Plaii update. Recommendations, if any, will 'incorporated in fUttire
Water System Capital Improvement:Plan revisions.
