Rafetelis Financial Consultants, Inc. was hired to conduct a comprehensive water cost of service study. A critical focus of the study was to encourage water conservation. Work sessions were conducted with the Water & Light Advisory Board and City Council to discuss setting water rate objectives and priorities. As a result of this work, the consultant proposed the addition of a third water rate tier. This third tier is structured to recover cost from the customers who place increased demands on the system during times of peak water production while sending a strong pricing signal that Columbia values water conservation.
An interested parties meeting was held on November 7, 2018 to gather public input on the proposed water rate structure. An online survey was also available for additional public comments and questions.
The water rate structure was approved by City Council on January 22, 2019, and went into effect at that time.
The purpose of the water rate structure:
The purpose of the water rate structure is to encourage water conservation.
How the water rate structure works:
A third tier is in effect during the summer months of June, July, August and September to help encourage water conservation.
Water tiers during the summer months are based on the winter average consumption of each account. Winter average consumption is the customer’s average water use during the immediate preceding billing periods of January, February, and March and is updated annually.
Winter average consumption determines each individual customer’s tier cutoffs during the summer months of June, July, August and September.
Summer Tier 1: usage of 0% to 70% of winter average consumption
Summer Tier 2: usage of 71% to 170% of winter average consumption
Summer Tier 3: usage exceeding 170% of winter average consumption
All non-summer usage is billed at one flat rate per CCF.
Residential customers with a winter average consumption of less than 4 CCF will be assigned a winter average consumption of 4 CCF.
1 CCF = 748 gallons of water
