ITEM 1.01  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

(a)  Change of Control  Severance  Agreement.  On April 17,  2006,  the Board of
     Directors  of  Southwest  Water  Company,   a  Delaware   corporation  (the
     "Company")  approved the form of a Change of Control  Severance  Agreement.
     All "named  executive  officers," as that term is defined in Item 402(a)(3)
     of Regulation S-K, other than Anton C. Garnier,  are eligible to enter into
     the Change of Control Severance Agreement  ("Agreement"),  should they wish
     to do so. The Board of  Directors  of the Company  may,  from time to time,
     permit other key employees of the Company to enter into the Agreement.  The
     Change of Control Severance Agreement has a term of three (3) years subject
     to  automatic  renewal  for  three-year  terms,  unless a 90-day  notice of
     non-renewal  is given  prior  to the  expiration  of a  current  term.  The
     Agreement  terminates  prior to a change of control upon the termination of
     employment  of the  named  executive  officer  or other  participants.  The
     Agreement  provides that the named executive officers or other participants
     will, upon a change of control (as defined in the  Agreement),  be entitled
     for a period of two (2) years  thereafter,  to a severance  payment if such
     person's  employment  is  terminated  by the  named  executive  other  than
     participants  for good  reason  (as  defined  in the  Agreement)  or by the
     Company  for other than good cause (as  defined  in the  Agreement).  Named
     executives  or other  participants  will be entitled to severance pay in an
     amount up to 2.99  times the sum of their  most  recent  base  salary  plus
     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.  All severance benefits payable under
     the  Agreement  will be limited so that no excess  parachute  payments,  as
     defined in Section 280G of the Internal  Revenue Code, will result.  A copy
     of the form of Change of Control  Severance  Agreement  is attached to this
     report as Exhibit 10.1.

(b)  Executive Employment Agreement.  On April 17, 2006, the Company and Mark A.
     Swatek entered into an Executive  Employment  Agreement,  pursuant to which

     commencing  May 15, 2006. The material terms of the Agreement are (i) Term:

     Salary  with a  potential  of  100%,  in  accordance  with  criteria  to be
     established  between the Company  and Mr.  Swatek for 2006 and  pursuant to
     normal Company procedures thereafter. (iv) Relocation Assistance: Executive

     Littleton,  Colorado up to two trips a month for himself and his wife,  and
     he will be eligible for temporary housing until he acquires a new residence
     in the local area. (vi) Grant of Options: Executive will be granted options
     to purchase 75,000 shares of Company stock under the 2006 Equity  Incentive
     Plan following adoption of the Plan by the stockholders. Those options will
     vest 50% one year  following the date of grant and 50% two years  following
