Exhibit 24.1
LIMITED POWER OF ATTORNEY FOR SEC REPORTING OBLIGATIONS

Effective as of June 3, 2025 (the "Effective Date"), the undersigned hereby
constitutes, and appoints each of Jeffrey M. Taylor, Justin B. Ettelson, Mark
Fiore and Michael Iannello, or any of them acting singly, with full power of
substitution, as the undersigned's true and lawful attorney-in-fact to,
beginning on and as of the Effective Date:

1. Prepare, execute in the undersigned's name and on the undersigned's behalf,
and submit to the U.S. Securities and Exchange Commission (the "SEC") a Form ID
including amendments thereto, and any other documents necessary or appropriate
to obtain codes, passwords and passphrases, or to obtain the undersigned's
proper and required access as a filer, to enable the undersigned to make
electronic filings through the SEC's Electronic Data Gathering, Analysis, and
Retrieval ("EDGAR") system of reports required by Section 16(a) of the
Securities Exchange Act of 1934, as amended, and the rules and regulations
promulgated thereunder, each as amended from time to time ("Section 16(a) and
Related Rules"), and, in so doing, the undersigned hereby represents and
warrants to each such attorney-in-fact that the undersigned has not been
criminally convicted or civilly or administratively enjoined, barred, suspended
or banned in any capacity, as a result of a federal or state securities law
violation;

2. Act as my account administrator and do all things necessary or desirable with
respect to my EDGAR account, including with respect to my enrollment in EDGAR
and the maintenance of my EDGAR account;

3. Prepare, execute for and on behalf of the undersigned, in the undersigned's
capacity as an officer and/or director of American Water Works Company, Inc.
(the "Company"),  Forms 3, 4, and 5 in accordance with Section 16(a) and
Related Rules, and Form 144 in accordance with Rule 144 promulgated under the
Securities Act of 1933, as amended, and the rules and regulations thereunder
(the "1933 Act"), including any amendments thereto, relating to the securities
of the Company, and file the same with the SEC and any securities exchange in
accordance with Section 16(a) and Related Rules and the 1933 Act, respectively;

4. Seek or obtain, on behalf of the undersigned, information on transactions
in the Company's securities from any third party, including brokers, employee
benefit plan administrators and trustees; the undersigned hereby authorizes any
such person to release any such information to the attorney-in-fact and
approves and ratifies any such release of information; and

5. Perform any and all other acts for and on behalf of the undersigned that,
in the discretion of such attorney-in-fact, are necessary or desirable in
connection with the foregoing.

The undersigned hereby grants each such attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
necessary or appropriate to be done in the exercise of any of the rights and
powers herein granted, as fully to all intents and purposes as the undersigned
might or could do if present, with full power of substitution, hereby ratifying
and confirming all that such attorney-in-fact, or such attorney-in-fact's
substitute or substitutes, shall lawfully do or cause to be done by virtue of
this Limited Power of Attorney. The undersigned acknowledges and the foregoing
attorneys-in-fact, in serving in such capacity at the request of the
undersigned, are not assuming, nor is the Company assuming, any of the
undersigned's responsibilities to comply with Section 16 of the Securities
Exchange Act of 1934 or the 1933 Act.

The Limited Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 144, 3, 4, and 5 with respect
to the undersigned's holdings of and transactions in the Company's securities,
unless earlier revoked by the undersigned in a signed writing delivered to each
such attorney-in-fact. In addition, this Limited Power of Attorney shall
automatically be revoked as to any attorney-in-fact constituted or appointed
hereunder upon termination of such person's employment with the Company. This
Limited Power of Attorney shall constitute an automatic revocation of any prior
Limited Power of Attorney executed by the undersigned with respect to the
subject matter hereof.

IN WITNESS WHEREOF, the undersigned has caused this Limited Power of Attorney
to be executed as of this 3rd day of June, 2025, to be effective as of the
Effective Date.
