Accepted Rates

Pursuant to Chapter 11, Section 11-125 and Section 11-164 of the Code of Ordinances of the City of Somerville, the tables below outline the amended water and sewer volumetric rates for the Fiscal Year 2020 (FY20). Given the substantial need for investment in our aging and fragile water and sewer system and the increasingly strict regulatory environment we confront, the Administration’s original rate proposal, submitted on March 25, 2019, included increases of 6% for water and 7.5% for sewer. The Council rejected these rate increases on May 9, 2019.

Though the Administration continues to emphasize that the original rate proposal is the appropriate and responsible choice in light of our system needs, we now submit the following amended rate proposal:

  1. A 5% increase in water volumetric charges;
  2. A 5.5% increase in sewer volumetric charges;
  3. No change to existing base charges for both water and sewer; and,
  4. The creation of a Discount Tier for all ratepayers billed tri-annually that aims to provide particular relief to low-volume users.

The first table on the next page describes the updated residential tiers, which reflect the addition of the Discount Tier for any usage under 8 units [748 gallons per unit x 8 units, or 5,984 gallons of water].

If you have any questions, please contact me at jdeluca@somervillema.gov.

For additional information about these water and sewer rate changes, please see the rate recommendation memorandum from our consultant, Woodard & Curran.
