Water/sprinkler truck

A water/sprinkler truck is a chassis with a tank and nozzles for washing roads, dust suppression in heat, knocking down dust on sites and watering city greenery. It usually carries a front spray bar and often a water cannon for watering at a distance.

The value is in the water gear, not the truck itself: the pump, the nozzles and the inside of the tank (corrosion, sediment). Match the tank size to your route length so you are not forever stopping to refill. MAN and Mercedes-Benz chassis with the bodywork come from Germany; budget Howo units straight from China.
