If you are with any other governmental jurisdiction, please contact your hotel to verify their specific policies. If the hotel does not extend the per diem rate to your governmental jurisdiction, your room will be charged at the WEFTEC group rate.
Alert! Convention Management Resources (CMR) is the official hotel management company for WEFTEC. No other hotel management company or travel agency is authorized to place reservations on behalf of the Water Environment Federation. Other agencies have not entered into agreements with the Chicago hotels and are not able to guarantee rates and accommodations during the dates of the conference. Should you be contacted by any agency other than CMR, please send us a message.
