Installation in Conroe: what to know

A new or replacement system starts long before any digging. In Conroe's unincorporated and rural stretches, installation begins with a licensed soil and site evaluation and a permit through Montgomery County Environmental Health Services. The soil results largely decide the design: on the dense clay that covers much of the area, an aerobic spray system is often chosen over a conventional drain field, especially on smaller lots.

Cost is driven by the system type the soil calls for, lot size and access, and how the field has to be laid out — not by a flat rate. Getting the evaluation and permit right up front avoids redesigns later.

If the property sits within 2,075 feet of Lake Conroe, the San Jacinto River Authority permits the system instead of the county, with stricter design and maintenance rules built in from the start.

Installation in Conroe — FAQ

Who permits a new septic system in Conroe?

For most of the rural and unincorporated area, Montgomery County Environmental Health Services handles permitting, starting from a licensed soil and site evaluation. If the property lies within 2,075 feet of Lake Conroe, the San Jacinto River Authority permits it instead, with stricter design and maintenance requirements.

Will I need an aerobic system or a conventional one?

That is decided by the soil and site evaluation, not by preference. Much of the Conroe area has sandy topsoil over slow-draining clay, so aerobic spray systems are frequently the design that fits — particularly on smaller lots where a conventional drain field would need more room than the soil allows.
