It is not always easy to source a stable hot water supply at any time and anywhere, after all.

How to Dispose of Grey Water?

Grey water is a kind of wastewater from the sink on your mobile food trailer. It may have grease, food remains, and dirt after you use water to wash hands or clean used utensils. Where does the grey water go when it goes into the sink drain? A sewer, or ground? According to regulations, most regions require, grey water should not be discharged outside without any treatment. That means that a container for storing the grey water in your food trailer is necessary.

Our food trailer is outfitted with a 25L plastic grey water tank under the hand sink. With a grain pipe, used water is discharged into the grey water tank. If your demand for water is huge, there is another solution for you. You can pay extra to have an 82L grey water tank. Given its large volume, it should be installed under the food trailer. The installation is totally free. You can empty a full grey water tank at a dump station, which is a legal and environmental-friendly approach.

Why Do You Need a 3 Compartment Water Sinks in Your Catering Trailer?

A standard hand sink is one of the fixtures of your mobile catering trailer, no matter which state you are in. According to federal and local regulations in the US, the food trailer should have sinks with 3 compartments, which are used for washing, rinsing, and sanitizing.
  • Washing: This compartment is used for washing equipment that has come into contact with food, like knives.
  • Rinsing: The second compartment is used for rinsing the washed equipment at a temperature of above 40℃.
  • Sanitizing: This compartment is full of sanitizing solutions for soaking washed cooking equipment.

The 3 compartment sink for the food trailer must be kept away from the cooking area. We prefer to install it near the rear workbench in the process of building a custom food trailer. In addition, there is a stainless steel splash guards on the sides and rear of the hand sink, which ensures a clean and neat working environment.

Of course, things differ in the UK. A catering trailer water system should have a hand sink with 2 compartments for washing your hands and cleaning cooking equipment, according to the local authorities. We will choose the right wash sink for your mobile catering trailer.

Tips For Choosing the Right Water Tanks

As an integral part of the catering trailer water system, water sinks are a carrier for storing clean water in your catering trailer. Like the design of a food trailer, these must meet the permits and regulations required in your state. Here are some tips for choosing the right water tanks when you build a custom food trailer.


1. The Bigger the Water Tank is, the Larger Van you Need

A big water tank gives you confidence in operating a mobile catering trailer business. But, is it necessary for you to go everywhere with an 80L water sink? In fact, no! Every liter of water is about 2 pounds. 80 liters of water add an extra 160 pounds to your mobile food trailer. A 3.25*2.15*2.25 mobile food trailer is about 650gk, which can be easily towed by a car, even if it is outfitted with kitchen equipment. But, an extra 80L water tank makes everything hard to move.
Honestly, 50L of water is enough for the operation of an ice cream trailer business. Every food trailer we built has 2 water tanks whose volume is 25L. We send it with your food trailer with no extra fee.


2. Find Out the Requirement in Your State

There are 2 types of water tanks we provide. One is a 25L plastic water tank that is free, and the other is a 130L stainless steel water tank. The owner of a burger trailer prefers the latter because of his huge demand for water and business. However, stainless steel water sinks are legally banned in some states. For example, Los Angeles says that the material of a food trailer’s water tank should not be stainless steel or aluminum. You can contact us now, and we will tell you which type of water tanks you should have.

3. Don't Forget the Grey Water Tank

The grey water tank should be larger than your clean water tank. There are 2 options for you: a 59L grey water tank, or an 82L grey water tank. Given their capacity, tanks are installed under the trailer, with an outlet for discharging exhaust water. Speaking of small food trailers, 25L grey water is a perfect choice. You can put the tank under the wash sink and put the pipe in it.

Don’t put attention to the price or model only when you buy any food trailer. The catering trailer water system is important as well.
