North Houston's septic company, end to end
On-Site Sewage Facility of Texas serves homeowners and business owners across Montgomery, Waller, Liberty, Harris, San Jacinto and Polk counties, and the surrounding area of Texas.
Our goal is to simplify the subject of your septic system and reduce the anxiety that goes along with it, so you can make an informed decision about its care and maintenance.
We offer a wide array of services for the home or business owner — from a very simple issue through to complex, large installations. In each case the aim is the same: find the answer and the most economical solution that lets your system function the way it was designed to.
That means we don’t start with a product. We start with the ground. A site and soil evaluation determines what your property can support, the design follows the soil, the installation follows the design, and maintenance keeps the whole thing honest.
Because we handle every stage, nothing gets lost between contractors. The people who evaluated your site are the same people you call three years later when a light comes on at the control panel.
