All users of the wastewater system are assessed a monthly sewer user charge which is reflected on the water bill provided by the Terrebonne Parish Consolidated Waterworks District. Ordinance No. 7822, adopted May 28, 2010, amended the Parish Code pertaining to sewer user charges.
Sewer user charges are summarized as follows: (fixed charges + user charge + energy adjustment charge)
Fixed charges (per month)
All customers, except hotels/motels
Hotels/motels (total rooms)
Occupied apartment units/trailer park spaces
All customers pay $1.76 per 1,000 gallons of water used.
Energy Adjustment Charge
All customers pay approximately $0.50 per 1,000 gallons of water used, subject to recalculation each month.
The user charge of $1.76 became effective on June 1, 2010, and will be adjusted on January 1st, each year through 2014: For the year 2011, $1.82; for the year 2012, $2.18; for the year 2013, $2.23; for the year 2014, $2.28.
The energy adjustment charge is calculated each month by means of a "Moving Average Method" using the cost of all electrical energy consumed during a 3-month period prior to the current billing period divided by the total water sales during that same period.
An example of the monthly sewer bill during 2013 would be calculated as follows:
If a residential customer uses 6,000 gallons of water per month, the bill would be:
$ 2.23 x 6 = $ 13.38
Energy Adjustment Charge:
$ 0.50 x 6 = $ 3.00
Terrebonne Parish Government is genuinely concerned about the quality of life in the parish as well as the preservation of our natural resources. Being a coastal community, parish residents utilize the area lakes, bays and bayous extensively for recreation and for their livelihood. The discharge of untreated or partially treated wastewater into our environment threatens our water quality and thus, our quality of life. Therefore, proper collection and treatment of wastewater is essential to our community.
