Wastewater tanks, also known as grey water tanks, are where all used and contaminated water will go once they are generated. This will always be on board your truck until you get an approval to create a disposal station. Food truck grey water is waste water generated from your truck’s hand and three compartment sinks, which must be disposed of in a health department approved grease interceptor at your commissary or commercial kitchen.

Note that grey water differs from water from the toilets (very few food trucks have toilet facilities unless you have a full sized trailer you use as a mobile food platform) which is designated sewage or black water to indicate it contains human waste. And since wastewater contains perishable items such as food particles and grease, the grey tank must always be handled carefully.

Grey water tanks are expected to be bigger than your fresh water tank because they will be storing more than just used water. In most situations, food particles and other beverages make their way into the grey water tank through the sink in the food truck.

So if you have adequate space, you can place the grey water tank under your truck. This will allow your truck to accommodate more kitchen equipment. In a case where the grey tank can’t be placed under the truck, you can mount it under the sink inside your food truck.

Grey and fresh water tanks that are excessively big will be a problem in the long run and may even add to the weight of your vehicle. In case you are not sure of the specific size to go for, a typical food truck should have a freshwater tank with a 30 – 35 gallon capacity and a grey water tank with a 50 – 55 gallon capacity. Bear in mind that 1 gallon will weigh up to 8 pounds.

However, do not forget that your local health department may also have recommended tank sizes for your vehicle. Whatever your decision is, make sure you settle for tanks with the right capacity so you don’t run into problems while running your business.

If you are searching for these tanks online in specific sizes, you can look up RV water tanks or recreational vehicle water tanks. The water tanks used in food trucks are the same as those installed in RVs, campers, and tiny houses. The only difference is you may have a specific size requirement based on your operational needs, permitting requirements, and vehicle requirements.

Finally, while you may not want to go too small with a water tank, make sure you don’t go too big either. For every gallon of water, you will be adding an extra 8.34 pounds of weight to your vehicle. This water weight can add up fast as 5 gallons of water would be approximately 41.7 pounds.
