Update: Sanitary Sewer Cleaning and Televising Schedule

Dear Harris County MUD 374 Resident,

Thank you for cooperation over the last few weeks as Inframark on behalf of Harris County MUD No. 374 has been performing the sanitary sewer cleaning and TV inspection of the Harris County MUD No. 374 sewer collection system in sections 4, 5 and a portion of 7. This cleaning and inspection is necessary in order to evaluate the sanitary sewer. Over the next few weeks, we will continue to work in sections 6 and the remainder of section 7. Please see below for the new approximate completion date:

Date that work is expected to begin: Monday 04/11/2022

Approximate Completion Date: Wednesday 05/11/2022


  • Water and drains may be used as normal.
  • You will most likely not even notice that any work is being performed.
  • On very rare occasions your house may be affected as follows:

Sewer lines can develop air pressure or a partial vacuum from the cleaning process.  Usually any excess air pressure or vacuum will dissipate through your plumbing vents, but occasionally there are homes with inadequate plumbing vents (no vents, undersized vents or obstructed vents).   In the case of inadequate venting air pressure could escape through your toilet floor, sink, tub or shower drains causing water splash out (close the toilet lids) or, a vacuum could draw the water out of your fixture traps causing an unpleasant odor.

If you should experience an unpleasant odor, run water into each drain to re-fill the traps.

Thank you for your cooperation.
