Contracts

Aerobic maintenance contracts, explained

What Texas law says your contract must include, when it is due, and what happens if it lapses.

The first two years

Every new aerobic system starts with an initial two-year service policy. For a new home it starts on the date of sale by the builder. A copy goes to the permitting office before the system is approved for use.¹

What every contract must include (30 TAC 285.7)

The items covered
How fast the provider will come after you complain
The name of the licensed maintenance provider responsible
How often routine maintenance, testing and reporting happen
Who maintains the disinfection (chlorine) unit
The provider's physical business address and phone number

Renewals

Unless you maintain the system yourself under the rules, you must file a new signed contract with the permitting office at least 30 days before the current one expires. If a provider drops your contract, they must notify you and the permitting office in writing at least 30 days ahead.¹

Can I maintain it myself?

State rules allow some single-family homeowners to maintain their own system, but counties can add training and reporting requirements.¹ Bexar County's page says owners are responsible for keeping a service contract on file after the first two years.² Ask your permitting office before dropping a contract.

Comparing contracts

Questions

How often must my aerobic system be inspected?

At least every four months under a maintenance contract, or every six months with approved electronic monitoring, per TCEQ.

What if my contract expires?

You need a renewed contract filed at least 30 days before it expires unless you qualify to self-maintain. Contact your permitting office.
