ITEM 1.   BUSINESS.

GENERAL

Dominguez Services Corporation (Company) is a holding company created in 1990
through an Agreement of Merger with Dominguez Water Corporation.  Dominguez
Services Corporation's principal business is the ownership of all the common
stock of Dominguez Water Corporation.  The holding company structure provides
operational and financial flexibility and allows the Company to engage in non-
utility activities.  Currently, Hydro-Metric Service Corporation is the
Company's only non-utility subsidiary.  Substantially all of the Company's
revenue and profits in 1995 were from Dominguez Water Corporation.

Dominguez Water Corporation (Dominguez), a public utility, produces and supplies
water for residential, commercial, public authority, business and industrial
customers.  It is comprised of a South Bay division and the utility subsidiaries
Antelope Valley Water Company (Antelope Valley), Arden Water Company, Kernville
Domestic Water Company, Lakeland Water Company and Split Mountain Water Company.
The last four companies noted above, and their subsidiaries, collectively make
up the Kern River Valley Water Companies (Kern River Valley).

Dominguez was organized in 1937 as successor to Dominguez Water Company.  Its
South Bay division is the largest service area with 32,092 customers
encompassing most of the City of Carson, one-third of Torrance, and portions of
the cities of Compton, Long Beach and Harbor City.  Antelope Valley , with 1,228
customers, has four distinct service areas in northern Los Angeles County
whereas Kern River Valley, located in Kern County around Isabella Lake, has nine
distinct service areas and 3,419 customers.

OPERATIONS

In 1995, Dominguez supplied 12,371 million gallons of water to 36,739 customers,
compared to 12,071 million gallons of water to 36,371 customers in 1994.  The
South Bay division produced 11,890 million gallons of water in 1995. Although
Dominguez has a diversified customer base, 53% of 1995 water sales were derived
from business and industrial.  Furthermore, a single customer, a refinery,
accounted for 37% of these business and industrial sales.

Hydro-Metric Service Cooperation operates a large meter test and repair business
in Southern California.

WATER SUPPLY

The water supplies for Dominguez are from its own groundwater wells plus two
water wholesalers of imported water.

All service areas obtain either a portion of or all of their supply from
groundwater wells.  The quantity that the South Bay division is allowed to pump
over a year's time is fixed by court adjudication.  The adjudication established
distinct groundwater basins which are managed by a court appointed watermaster.
The groundwater management fixes the safe yield of the basins and ensures the
replenishment of the basins by utilizing impounded storm water and purchased
water when necessary.  Groundwater basins have not been adjudicated in the
subsidiary areas of Kern River Valley and the Antelope Valley.

Overall groundwater conditions continue to remain at adequate levels.  Dominguez
continues to drill new wells, so that it can maximize pumping its total
adjudicated rights when called upon.

The South Bay division and Leona Valley service area of Antelope Valley also
purchase water from wholesalers to supplement groundwater.  The South Bay
division purchase imported water from the Metropolitan Water District (MWD) of
Southern California.  The Leona Valley service area purchases its imported water
from Antelope Valley - East Kern Water Agency (AVEK).  Both of these wholesale
suppliers obtain water from the California State Water Project (SWP), and MWD
also obtains water from the Colorado River.

As of March 1996, the water supply outlook is very favorable.  Winter rains have
filled SWP reservoirs to above average levels.  MWD also indicates that a full
compliment of Colorado River water is available.  Dominguez expects an ample
supply of import water to be at hand for the next several years.

Long-term imported water supplies are dependent upon the outcome of several
factors.  Dominguez's future dependency on imported water will be subject to the
availability of reclaimed water in the region as well as customers' long-term
water conservation efforts.  Dominguez has been and will continue to promote
long-term water conservation efforts.  Dominguez  will continue to be an
industry leader in the promotion of wise water use.

Dominguez anticipates that the West Basin Municipal Water District Reclamation
Project will be delivering reclaimed water into the South Bay division by 1997.
Dominguez will make the reclaimed water (which is priced lower and more
economically) available to its customers.  Dominguez's margins will remain equal
to that of replaced potable sales.  This project is expected to be a major step
in drought-proofing the South Bay division.


                                        3
<PAGE>


Legislative actions continue to alter the amount of SWP water available from
Northern California, and MWD anticipates losing two-thirds of the water normally
imported from the Colorado River around the beginning of the next century.  The
reduced availability of imported water supplies and an annual population growth
of 400,000 in Southern California could create future drought conditions which
may require water rationing by all water agencies, including Dominguez.

WATER QUALITY

Water quality is a primary concern for Dominguez.  Groundwater requires only
minimal treatment with chlorine for disinfecting, with the exception of minor
water supplies in Kern River Valley that are filtered for iron and manganese.
Purchased water has already gone through an extensive treatment process before
receives it.

Both groundwater and purchased water are subjected to extensive quality
analysis.  With the occasional bacteriological minor exception, Dominguez meets
all current primary water standards.  Dominguez has an ongoing groundwater
monitoring program and South Bay division participates in an area-wide water
quality program administered by the association representing the groundwater
basins.

Under the federal Safe Drinking Water Act (SDWA), Dominguez is subject to
regulation by the United States Environmental Protection Agency (EPA) and the
California Department of Health Services for the quality of water it supplies.
The EPA is required by SDWA to continue establishing new maximum contaminant
levels for additional chemicals.  The costs of future compliance are currently
unknown and Dominguez's water sources may require additional treatment.
Management believes that Dominguez's resources are sufficient to meet these
anticipated challenges.

REGULATORY AFFAIRS

In August 1995, Dominguez increased revenues by $1,400,000 annually, or 6.2%, to
recover the increased cost of water production in our South Bay division.

This rate increase substantially recovered the total cost increase of $1,500,000
for higher purchased water costs and an increased pump tax.  However, due to
Dominguez's high earnings at this time, the total cost increase was not
recoverable in rates.  Dominguez expects to recover the difference, $100,000, in
the balancing account in the future.  This rate increase does not increase the
earnings to Dominguez but rather offsets the effects of higher water production
costs to Dominguez.

In 1995, the California Public Utilities Commission (CPUC) undertook a strategic
planning process referred to as Vision 2000.  This planning process was done in
response to hearings held by the California Legislature concerning the
organization


                                        4
<PAGE>


of the CPUC and the effects that deregulation in other utility industries will
have on the CPUC.  The CPUC held workshops throughout the state.  Dominguez
participated in these workshops and submitted comments.  The CPUC's Vision 2000
has been presented to the California Legislature.  In 1996, the California
Legislature will assess Vision 2000 plan and decide if further legislative
action is needed.

Discussions regarding Vision 2000 indicate that Dominguez will continue to be
subject to traditional regulatory policies and practices.  The regulation may be
modified to include performance standards.  Using performance-based rate making,
the utility and the CPUC would agree to a set of operating efficiency ratios.
If the efficiency ratios are exceeded, the shareholders would get to keep a
portion of the cost savings as increased profits.

NON-UTILITY SUBSIDIARY

Hydro-Metric Service Corporation is a service company specializing in field
testing and repair of large water meters.

EMPLOYEE RELATIONS

As of December 31, 1995 there were a total of 82 employees in utility and
non-utility operations.  None of the employees is represented by a labor
organization, and there has never been a work stoppage or interruption due to a
labor dispute.  In general, wages, hours, and conditions of employment are
equivalent to those found in the industry.  Dominguez considers its relations
with its employees as excellent.  All employees receive paid annual vacations
and sick leave.  Dominguez provides and pays the cost of group life, disability,
medical and dental insurance, as well as pensions for its employees.

ENVIRONMENTAL MATTERS

Dominguez's operations are subject to pollution control and water quality
control as discussed in the "Water Quality" section.

Other state and local environmental regulations apply to Dominguez operations
and facilities.  These regulations are primarily related to the handling,
storage and disposal of hazardous materials.  Dominguez is currently in
compliance with all other state and local regulations.

ITEM 2.   PROPERTIES.

Dominguez general administrative and executive offices are located on 5 1/2
acres of company-owned property at 21718 South Alameda Street, Long Beach,
California.  The offices and shops were completed in April 1972.

The South Bay division has 14 wells, some of which are located on its own land
and some on leased sites. Well sites under lease expire between 1996 and 2010
and require aggregate annual payments of approximately $100,000.  South Bay
division water storage, all on owned property, consists of a 5 million gallon
steel tank, four 3-1/2 million gallon steel tanks, one 750,000 gallon elevated
steel storage tank and other smaller storage tanks. Kern River Valley and
Antelope Valley operate approximately 45 wells and utilize approximately 20
storage tanks ranging in size from 40,000 to 300,000 gallons.

The South Bay division has prior rights to lay distribution mains and for other
uses on much of the public and private lands in its service area.  Dominguez'
claim of prior rights is derived from the original Spanish land grant covering
the Dominguez service area.  For this reason, Dominguez, unlike most other
public utilities, generally receives compensation from the appropriate public
authority when the relocation of its facilities is necessitated by the
construction of roads or other projects.  It is common for public utilities to
bear the entire cost of such relocation.

Substantially all of the property of Dominguez is subject to the lien of the
Trust Indenture dated August 1, 1954, as supplemented and amended, to Chemical
Trust Company of California, as Trustee, securing the three outstanding series
of Dominguez' First Mortgage Bonds.

ITEM 3.   LEGAL PROCEEDINGS.

On or about November 20, 1995, Dominguez's insurance carrier settled the claims
of a former employee who filed a complaint in Los Angeles Superior Court
alleging, among other things, that he had been wrongfully terminated by
Dominguez.  The terms of the settlement will have no adverse financial impact on
Dominguez.

ITEM 4.   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.
