PURPOSE
To provide guidance in determining provisions for accepting a sewage
pump station by Otay Water District in lieu of a gravity sewer for
serving a land development.
The provisions set forth in this policy describe circumstances and
considerations whereby the Otay Water District will accept a sewage
pump station as a District facility. These provisions are applicable
for serving land areas within the District and land areas annexed to
the District for sewer service.
BACKGROUND
To achieve orderly development of sewerage facilities within the Otay
Water District, the construction of a sewage pump station to serve a
land development shall be considered only under special circumstances
indicated in this policy.
Acceptance of sewerage system facilities by the Otay Water District,
shall be subject to the developer constructing facilities to District
requirements.
Because Operations and Maintenance (O & M) costs are substantially
more for pump station facilities than for gravity sewers, contribution
of funding for future pump station O & M costs is considered a
necessary part of a pump station becoming a part of District
facilities.
POLICY
In order to minimize additional operation and maintenance costs to the
District and to control orderly development of District sewerage
facilities, the following provisions shall be the basis for
considering requests for the District to allow construction of a
sewage pump station in lieu of construction a gravity sewer and for
the District's acceptance of a sewage pump station for Operation and
Maintenance.
1.Sewage pump stations will not be considered an acceptable means
of serving a land area when construction of a gravity sewer system is
possible and would be in the best interest of the District.

2.When a gravity sewer cannot be constructed to serve a land area
because of geographic or topographic reasons or other features that
would make its construction detrimental to the public or the
surrounding land area, a pump station may be considered. The proposed
pump station must satisfy the following criteria:
a.The total capital costs for the pump station must be provided by
person(s) or development requesting the pump station.
b.The pump station must have sufficient capacity to serve the
entire drainage basin that may possibly contribute flow to the
pump station, and
c.The pump station design and construction must meet standards
acceptable to the Otay Water District.
3.If the possibility exists that this pump station or project may
be converted to a gravity system in the future, the person(s) or
development requesting this pump station shall provide easements and
install pipelines acceptable to the District for the conversion.
4.In the consideration for a pump station to serve a land area, the
payment of pump station operation and maintenance (O & M) and
replacement costs shall be satisfied by one or more of the following
provisions:
a.A lump sum payment by the person(s) or development requesting the
pump station shall be made to the District in an amount
sufficient to cover the O & M and replacement costs estimated by
the District for the life of the pump station; or
b.A special District connection fee charge to each equivalent
dwelling unit served by the pump station shall be established by
an Otay Water District Ordinance. The special connection fee
shall be based on the estimated O & M and replacement costs for
the life of the pump station; or
c.A special monthly zone service charge collected in accordance
with a special District Ordinance section. The zone service
charge shall be adjusted periodically to provide sufficient funds
for annual O & M and replacement. Because of high administrative
costs, this method of payment should be considered only in
special circumstances where (1) a small number of individual

residences are served and (2) the special zone of service has
been requested mutually by the homeowners served.
The selection of one or more of the above provisions for O & M and
replacement costs shall be recommended by the General Manager after
considering the best interests of the District and the effected
residents. The Otay Board of Directors shall make a final
determination of the acceptable provisions(s) for allowing a sewage
pump station.
