  • Carpet cleaning, tile cleaning, and pressure washing wastewater discharge rules.

    Carpet cleaning, tile cleaning, and pressure washing waste water discharge rules.

    As amended in 1972, the law became commonly known as the Clean Water Act (CWA). The 1972 amendments: Established the basic structure for regulating pollutant discharges into the waters of the United States. Gave EPA the authority to implement pollution control programs such as setting wastewater standards for industry.

    Each city, state, county might have slightly different rules but for the most part the rules are similar an will include that professionals that remove dirty water from a job site causes the water to be classified as hazardous waste. So rule #1, do not remove the water from the job site. It is your customer's water and dirt, you leave with them.

    Do not allow water to run into the streets or storm water street drains. Water is to be disposed into the waste water sewer treatment system and must be free from fibers, lint, rocks and must be of a neutral pH. I some case water can be disposed in the customer landscape but you will have to make it does not contain petroleum distillates and VOC's. Water should not be of elevated temperatures (hotter than hot tap water, 140 degrees F.)

    Each company that discharges wastewater, must be permitted. This means all carpet cleaning, tile cleaning, and pressure washing companies have to register their company with their local wastewater treatment center or state environmental agency.

    Multi Sector General Permit TPDES General Permit No.TXR050000 Part II Section A Required for:
    Industrial facilities that qualify for coverage under this general permit may discharge the following non-stormwater discharges through outfalls identified in the SWP3, according to the requirements of this general permit:
    (d) water from the routine external washing of buildings, conducted without the use of detergents or other chemicals;
    (e) water from the routine washing of pavement conducted without the use of detergents or other chemicals and where spills or leaks of toxic or hazardous materials have not occurred (unless all spilled material has been removed);
    Pressure Washing Area. If pressure washing is used to remove marine growth from vessels, the discharged water must be permitted as a process wastewater by a separate TPDES permit.

    Summary if you are a carpet cleaner you can make your equipment have auto pump out and drain direct into your customer toilet with some simple add on equipment.
    Mytee 7303 (Hose mount vacuum booster, adds more vacuum and automatic dump at the same time)

    HydroForce AC12H Automatic filter and drain system is installed between two sections of vacuum hose.

    Pressure washer vacuum recovery units will usually already have auto pump out.
    Goliath Trailermount
    (bottom of above page has a list of a bunch of different vacuum and pump out systems.

    Sometimes you can simply lay some sandbags in the street with your vacuum hose and catch the runoff and filter it and pump into the customer sewer clean out cap.

    You can also pressure wash and pick up the water right on the tool

    Some customers that drain their dirty water directly in the customers landscape usually just use a hose mount lint filter system
