The Numbers
Huffman, ZIP 77336, had 13,377 residents in the 2019–2023 estimates, with a median household income of $96,404 and 78.2% of homes owner-occupied. The median home was built in 1996. The largest single decade is the 2000s at 25.5%, but the 1980s are close at 20.7% and the 1970s add 15.4%.
That is a place of owner-occupied houses on room to spare, built over three decades, which is the profile of a septic area.

What Age Does to a Tank
A system put in during the 1980s or 1990s has had thirty years of pumping, or not. The usual failures at that age are the quiet ones: a baffle that has rotted off, a distribution box that has tilted or filled with roots, a field that is slowly losing its ability to absorb. None of them announces itself until the yard goes soggy or the toilets slow.
The least expensive moment to find out is a routine pumping, when the lid is already off. If it is already showing, the signs page will help sort a full tank from a failed field.
Which County Office
Huffman is in Harris County, and unincorporated, so the Harris County Office of the County Engineer's septic rules apply: a permit for a new, repaired or replaced system, drawings and a site evaluation from a registered engineer or sanitarian, and installation by a TCEQ-registered installer or the homeowner. Plan review takes three to five days.
