Consolidated Water Co. Ltd.,
P.O. Box 1114 GT
Grand Cayman
B.W.I.

Dear Sirs,

We have acted as Cayman Islands counsel to you, a Cayman Islands company ("the
Company"), in connection with the proposed sale by the Company of the following
securities to be registered on a Form F-3 Registration Statement, ("the
Registration Statement"), to be filed with the Securities and Exchange
Commission ("the Commission") pursuant to the United States Securities Act of
1933 ("the Act"):-

1.    215,714 ordinary shares of the Company ("the Shares").

In rendering this opinion, we have examined the following documents and
instruments:-

(1)   the Registration Statement (not including the Exhibits filed or to be
      filed unless mentioned below);
(2)   the Company's Certificate of Incorporation;
(3)   the Company's Memorandum and Articles of Association; and
(4)   the resolutions adopted by the Board of Directors of the Company
      authorizing the registration of the Shares pursuant to the terms contained
      in the Registration Statement.

We have also consulted with officers and directors of the Company and have
obtained such representations with respect to matters of fact as we have deemed
necessary or advisable for purposes of rendering this opinion, we have not
necessarily independently verified those factual statements, nor the veracity of
those representations, but we have no reason to doubt their truth or accuracy.

Based on the foregoing it is our opinion that the Shares to be registered by the
Registration Statement are validly issued, fully paid and non-assessable.

This opinion is issued on the basis that it will be construed in accordance with
the provisions of the laws of the Cayman Islands.

We consent to the use of this opinion as an exhibit to the Registration
Statement and to the reference to this law firm in the Prospectus under the
heading "Legal Matters". We further consent to the use in the Registration
Statement of the description of our opinions in the "Risk Factors" section under
the caption "Service of Process and Enforcement of Legal Proceedings Commenced
Against Us in the United States May Be Difficult to Obtain." In giving this
consent, we do not admit that we are in the category of persons whose consent we
understand is required under Section 7 of the Act or the rules and regulations
of the Commission promulgated under it.

Yours faithfully,

CHARLES ADAMS, RITCHIE & DUCKWORTH
