Sewer Service

Please note:

You do not need to contact the City to start or stop sewer service. This will happen automatically when the change of ownership is recorded with the County.

Your sewer charges are based on the amount of water used at your property during the winter months (November through March, depending on your Helix Water billing cycle). Water consumption information can be obtained by contacting Helix Water District.

Sewer Rates

Sewer rate information can be found in our Sewer Service Fees handout.
