What is the standard size of a car wash sedimentation tank?

The standard size of a car wash sedimentation tank is a length of no less than 8 meters and a width of no less than 6 meters. The following is relevant information: 1. Car wash sedimentation tank: A car wash sedimentation tank is a high-pressure multi-directional washing equipment designed for the tires and chassis of various engineering vehicles, in accordance with the requirements of municipal, construction, environmental, and transportation departments. 2. Standards for car wash facilities: Each construction site should connect a water pipe at the washing platform and equip it with high-pressure washing equipment such as a high-pressure water gun with a pressure of no less than 8 MPa. The length of the hose connected to the water gun should be no less than 10 meters. Additionally, based on the traffic of construction vehicles, no fewer than 2 dedicated personnel should be assigned, primarily responsible for washing material transport vehicles leaving the site.
The standard dimensions of a car wash sedimentation tank vary by region and regulations, but generally, the recommended length is between 6 to 8 meters, width of 3 to 4 meters, and depth of about 1.5 to 2 meters. This size can handle the wastewater flow of 20 to 30 vehicles per day. For example, in Shanghai, the Environmental Protection Bureau requires a minimum capacity of 5 cubic meters, with separate sedimentation and sludge zones to ensure thorough wastewater settling before reuse. When constructing the tank, I typically use concrete materials with a waterproof layer, and don’t forget to install a slope to guide water flow and prevent clogging. Regular maintenance is crucial—clean the sediment monthly; otherwise, sludge buildup will reduce efficiency and may even lead to fines. Compliance with size standards isn’t just about environmental protection but also saves money and hassle. I’ve seen small car wash shops face doubled costs due to drainage issues, so checking local standards like GB/T 50014 before designing is key.
