ITEM TITLE: Resolution - Granting Sewer Service Charge Variance to the
'8~( Community Hospital of Chula Vista J
SUBMITTED BY Director of Public Works/City Engineer j-)!)(1 /
ITEM EXPLANATION
The Community Hospital of Chula Vista has requested a variance from the
standard sewer service charge for its new site at 751 Dora Lane.
The Engineering Division has investigated the circumstances concerning
water usage and sewage generation at the site. Findings and a recommenda-
tion in favor of the variance are contained in the "Investigator's Report"
included with the application submitted herewith. This report has been
reviewed and approved by the City Manager.
The sewer service charge is normally based on water usage and the assumption
that a given portion of the water used enters the public sewers. However,
most of the water delivered to this site is used for irrigation and cooling
purposes. The report sets forth the assumptions and facts for granting
this variance and recommends that a uniform rate equal to 17~ of the water
billing be established for the Community Hospital of Chula Vista.

Application is hereby made for a sewer service charge rate review for the
following reasons:
It is estimated, based on the size of uur irrigation system and the frequency and
duration that it will run, that we will consume approximately 1, 328, 000 gallons/year
or 177, 606 cu. ft. /year of water. The monthly figures will vary, but the yearly
igures shod total out as shown above. Since our sewer service charge is
based on our water consumption (on the assumption that all water consumed
eventually enters the sewer system), our sewer charges will exceed our
actual utilization of the system because the irrigation water will not empty into
a sewer. Therefore, we request that our sewer service charge be reexamined
and an appropriate reduction made.

INVESTIGATOR'S REPORT
In moving from its previous location_pn "F" St. to the new site on
Dora Lane, the Community Hospital has increased i.ts demand for water,
Th's in r a ;s a~sPd b~~• 1) Exgandinct na i n a a.; y from 88 to
131; 2) Installing a central air conditioning system with an appurtenant
wat r .oo~~ng tower• and 3) rnvidinq 5 53 acres of landscapincr,
Based on a proration of patient capacities and the hospital's
will be used annually for general purposes. According to the hospital's
per ton of cooling capacity through evaporation. It is estimated that
a total of 257 647 cubic feet will be used to make u this loss annuall .
A recent survey o water consumption in city par s in icate t at.
landscaped areas require an average of 2,520 gallons of water per acre
der day. On an annual basis this would amount to 680;0,00 cu is eet
for the hospital.
In total, approximately 1,638,300 cubic feet of water is expected
to be consumed by the hospital annually while 700 660 cubic feet or
about 43%, would be subject to the sewer service charge. Ordinarily
55% to 85% of the water used is delivered to the sewer s stem.
RECOMMENDATION
It is recommended that a sewer service charge rate equal to 17% of
the water billing be established for the Chula Vista Community Hospital.
This rate is based on the ratio of sewage generation by the hospital
(.43) to the "Normal" sewage generation (.70} and the "Normal" service
charge for commercial users (28%).
As a condition of receiving this variance, the hospital should be
to maintain records of the amounts of cooling tower water lost
through evaporation and the total water delivered to the hospital.-
These records should be available for use by the City in connection with
periodic reviews of the variance.
