Car Wash Cleaning
liquid waste collected
of expertise
All commercial car wash businesses, have a series of pits installed in the wash bay. These pits collect and contain all wash water onsite, and at Harmor Liquid Waste Solutions we specialise in car wash pit cleaning.

Why do I need to remove the liquid waste from my car wash?
The drainage and recycling systems of a car wash are designed to separate the pollutants from the water.
Pollutants include:
- Car washing chemicals used
- Solids from cars (mud, dirt and road grime)
The pollutants collect in the collection pits of car wash bays and in the triple interceptor, prior to the water being recycled or going to sewer. Over time the collection pit drainage and triple interceptor fill with heavier solids/pollutants (build up). These are required (by trade waste agreements with water boards) to be emptied and treated at an EPA licenced facility.
How often do the pits and interceptors need to be emptied?
This is determined by the trade waste agreement that you need to have in place with your local water board.
What happens if I don’t empty my pits and inceptors?
Can my infrastructure be used, while the pits and interceptor are being emptied?
Yes, it is safe to do so.
How long does it take to empty?
Collected wash water can be recycled & reused after treatment, or it can be discharged to the sewer network via a triple interceptor pit.
The collection pits and interceptors need to be emptied and cleaned regularly.
Failure to empty your collection pits and interceptors, can result in substantial fines from your local water authority and may result in blocked pipes and pits and costly emergency repair bills.
To address this, we offer efficient and reliable car wash cleaning services.
