ITEM 1. BUSINESS

        This annual report on Form 10-K is a combined report being filed by two
separate Registrants: American States Water Company (hereinafter "AWR") and
Southern California Water Company (hereinafter "SCW"). References in this report
to "Registrant" are to AWR and SCW, collectively, unless otherwise specified.
SCW makes no representations as to the information contained in this report
relating to AWR and its subsidiaries, other than SCW.

GENERAL

        AWR, incorporated in 1998, is engaged in the business of holding, for
investment, the stock primarily of utility companies. AWR's principal investment
is the stock of SCW. SCW is a California public utility company engaged
principally in the purchase, production, distribution and sale of water (SIC No.
4941). SCW also distributes electricity in one customer service area (SIC No.
4911). SCW is regulated by the Public Utilities Commission of the State of
California (CPUC) and was incorporated on December 31, 1929. SCW is organized
into three water service regions and one electric customer service area
operating within 75 communities in 10 counties in the State of California and
provides water service in 21 customer service areas. Region I incorporates 7
customer service areas in northern and central California; Region II has 4
customer service areas located in Los Angeles County; Region III incorporates 10
water customer service areas in eastern Los Angeles County, and in Orange, San
Bernardino and Imperial counties. SCW also provides electric service to the City
of Big Bear Lake and surrounding areas in San Bernardino County through its Bear
Valley electric service division.

        AWR also owns two other subsidiaries. American States Utility Services,
Inc. (ASUS) contracts to lease, operate and maintain water and wastewater
systems owned by others and to provide related services, such as billing and
meter reading. Chaparral City Water Company (CCWC) is an Arizona public utility
company serving approximately 11,400 customers in the town of Fountain Hills,
Arizona and a portion of the City of Scottsdale, Arizona (SIC No. 4941). The
Arizona Corporation Commission (ACC) regulates CCWC. Neither AWR nor ASUS is
regulated by either the CPUC or the ACC.

        SCW served 246,799 water customers and 21,747 electric customers at
December 31, 2001, or a total of 268,546 customers, compared with 266,658 total
customers at December 31, 2000. CCWC served 11,353 water customers as of
December 31, 2001, compared with 11,063 customers at December 31, 2000. ASUS has
approximately 90,000 accounts under contract.

COMPETITION

        The businesses of SCW and CCWC are substantially free from direct and
indirect competition with other public utilities, municipalities and other
public agencies. AWR's other subsidiary, ASUS, actively competes with other
investor-owned utilities, other third party providers of water and wastewater
services, and governmental entities on the basis of price and quality of
service.

EMPLOYEE RELATIONS

        SCW had 481 employees as of December 31, 2001 as compared to 489 at
December 31, 2000. Seventeen positions in SCW's Bear Valley Electric customer
service area are covered by a collective bargaining agreement, which expires in
2002, with the International Brotherhood of Electrical Workers. Fifty-six
positions in SCW's Region II ratemaking district are covered by a collective
bargaining agreement, which expires in 2004, with the Utility Workers of
America. SCW has no other unionized employees.

        CCWC had 11 employees as of December 31, 2001, all of who are
non-unionized.
