Toilet dye test

Place 5–10 drops of food coloring or a dye tablet in the toilet tank, wait about 10 minutes, and check the bowl. Colored water in the bowl means the toilet is leaking.

Bring with you

Latest bill, billing stub, account number, ID if changing service, payment method, and proof if already paid.

Office vs bank branch

Use a GSWSA office for overdue handling. Approved bank branches require a billing stub and non-overdue account.

Using an outside payment website

GSWSA says external bill-payment websites are not associated with GSWSA. Direct payment is safer when timing matters.

Using personal bank bill pay too close to the due date

GSWSA says personal banking services may delay the payment reaching GSWSA.

Trying to pay overdue bills at bank branches

Approved bank branch payments require billing stub and non-overdue account. Overdue balances must be paid by phone or at the Administrative Office.

Mailing a payment after the due date is near

Payments are due 14 days after the bill date. Mail is not best for urgent payment proof.

Ignoring seven-day past-due notice timing

After the due date, penalty is added and a past-due notice gives seven additional days before disconnection may occur.

Calling a plumber first for sewer backup

GSWSA says to call them first so they can determine responsibility and possibly correct the problem at no charge.

Stopping manual payment before draft is confirmed

Draft payments occur on the due date. Watch the first cycle carefully and make any draft-account changes five days in advance.

Waiting to stop service

GSWSA requires at least 24-hour notice and disconnections can only be scheduled Monday through Thursday.
