(a)  Employment Agreements. On April 28, 2006, Southwest Water Company (the
     "Company") entered into Employment Agreements (the "Agreements" and each an
     "Agreement") with each of Cheryl L. Clary, Chief Financial Officer of the
     Company, and Michael O. Quinn, President, Utility Group.

     The Agreement with Ms. Clary provides for a severance payment of 0.75 times
     Ms. Clary's base salary and an additional cash payment of $25,000 should
     the Company under certain circumstances terminate her employment before May
     15, 2007.

     The Agreement with Mr. Quinn provides for a severance payment of 1.5 times
     Mr. Quinn's base salary and an additional cash payment of $25,000 should
     the Company under certain circumstances terminate his employment before May
     15, 2008.

     Copies of the Agreements are attached to this Report as Exhibits 10.1 and

(b)  Change of Control Severance Agreements. On April 28, 2006, Southwest Water
     Company (the "Company") entered into Change of Control Severance Agreements
     (the "Severance Agreements" and each a "Severance Agreement") with each of
     Cheryl L. Clary, Chief Financial Officer of the Company, and Michael O.
     Quinn, President, Utility Group.

     Each Severance Agreement provides that the executive will, upon a change of
     control as defined in the Severance Agreement, be entitled for a period of
     two (2) years thereafter, to a severance payment if executive's employment
     is terminated by the Company for other than good cause. The severance
