Notice of Requested Rate Adjustment

Oct 07, 2021
On Thursday, September 30, 2021, Maryland Water Service, Inc. (“MWS”) filed a request with the Maryland Public Service Commission seeking authority to increase its Maryland base distribution rates. MWS also requested approval for the consolidation of its water rates into uniform rate schedules for each customer class across all its water systems. In addition, MWS has proposed standardizing tariff terms and conditions across all such systems. MWS proposed an effective date of October 30, 2021, but the Commission has suspended the proposed rates for a period of 150 days from that date to allow it to conduct proceedings on justness and reasonableness of the proposed rate adjustment.
