Pay My Bill
Tennessee Wastewater recently partnered with Fiserv to enable paperless delivery of checks by most major banks' billpay services. This drastically reduces check processing time and helps our customers better anticipate when their checks will clear.

TWSI has updated statewide and Williamson County bonding rates effective September 1st (October 1st billing cycle) to reflect the latest TRA mandated true-up. These rates are expected to remain in effect until the next true-up period, which is currently projected to be the same time in 2018.

Payment Terms

A non-payment penalty of five percent (5%) of the monthly charge will be due after the due date shown on the bill (typically the 15th of the month). It is your responsibility to ensure that your payment arrives by the due date. Late penalties are processed on the day after the due date and will only be adjusted in the event of an extraordinary circumstance.

Credit Card payments can be made at any time through our online portal. If you choose to pay with Credit Card, a 3% Convenience Fee will be added to your total. We also offer an ACH Bank Draft service free of charge.

Tennessee Wastewater reserves the right to disconnect service if payment is not received within 30 days of the due date. Delinquent customers will be notified via Certified Mail of the time they have to settle their account before they risk disconnection. No service shall be reconnected if discontinued for non-payment (or any other valid reason) until all charges have been paid, including disconnection and reconnection fees. The disconnection fee is $40 and the reconnection fee is $50.

Service under any application may be discontinued for the following reasons:

1. Non-payment of bill
2. For misrepresentation in the application
3. For adding to the property or fixtures without notice to the Utility
4. For tampering with any service pipe, tank, control system, filter or any other facilities of the Utility in any way whatsoever
5. For violation of any rules of the Utility
6. For disconnecting or re-connecting service by any party, other than a duly authorized agent of the Utility, without the consent of the Utility

A check returned by the bank will incur a fee of $25.00.

Access Fee

The owner of each property parcel which is provided a service connection when the sewer system is built, will be required to pay an annual sewer access fee of $120.00. This fee will be due on the Januray 15th, for owners of record, as of December 1st of the given year. A non-payment penalty of five percent (5%) of the charge will be due after the due date shown on the bill. Tennessee Wastewater reserves the right to place liens on properties with sufficiently delinquent sewer access fees.

Pretreatment Requirements

For all sewage connections the Utility reserves the right to require any non-residential user to provide special pre-treatment for any high strength effluent before discharge into its sewage system. The Utility may, upon the basis of recognized engineering standards and treatment costs, increase the rate charged to cover the cost of treatment of high strength effluent or industrial waste, and may impose recognized engineering standards as to the maximum size of solids and constituents in such waste discharged into its sewage system.

System Abuse

If excessive volumes of sewage are received, the Utility may require the Customer to monitor flow volume and increase surge holding capacity at the Customer's expense. All customers will be required to follow the Do's and Don'ts list for an Effluent collection system, supplied to them by the Utility. These requirements prohibit the flushing of any toxic chemicals that kill tank bacteria, and disposal of an excessive amount of grease, pet hair, or non-biodegradeable products, among other things.

Terms of Service

The Utility shall maintain all tanks, control systems and service lines required to provide sewer service on the Customer's premises. The Customer must execute an agreement granting an easement to the Utility for maintenance of the sewer system. The Utility's responsibility for maintenance begins at the point of entry to the tank via the inlet tee. The building plumbing and Building Outfall Line are the responsibility of and shall be maintained by the Customer.
