ITEM 1.01     ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

(i)  Change of Control Severance Agreement. On August 18, 2006, Southwest Water
     Company, a Delaware corporation (the "Company") entered into a Change of
     Control Severance Agreements (the "Severance Agreements" and each a
     "Severance Agreement") with each of Stephen C. Held, President of the
     Services Group, and Shelley A. Farnham, Vice President of Human Resources
     of the Company.

     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. For Mr. Held the
     severance consists of 2.99 times the sum of the executive's most recent
     base salary plus the average bonus for the prior three full years. For Ms.
     Farnham the severance consists of 1.5 times the sum of the executive's most
     recent base salary plus the average bonus for the prior three full years.
     The severance benefits also include acceleration of vesting of previously
     granted stock options held as of the date of the change of control. Total
     benefits may not exceed the limits imposed by Section 280G of the Internal
     Revenue Code.
