Water Bowsers.

Only if it is road-legal — meaning it has the correct chassis, braking, lighting and, where required, type approval. Many bowsers are site-tow only and are not permitted on the public highway.

Check the specification before purchase. Towing a site-tow bowser on the road is an offence and invalidates insurance.

Baffles are internal partitions that limit the movement of water when the bowser is towed. Without them, a part-full tank surges under braking and cornering and can push the towing vehicle.

Any bowser intended to be towed with a partial load should be baffled — it is a genuine safety feature, not an upgrade.

Only if it is manufactured and certified for potable use, and has been cleaned and disinfected to the appropriate standard. Bowsers previously used for non-potable duty must not be switched to drinking water.

Potable bowsers should be dedicated to that purpose and kept sealed between uses.

Gravity outlets for simple filling, 12V pumps run from the towing vehicle, petrol engine pumps for higher flow away from power, and mains pumps for static installations. Spray bars and lances are common for dust suppression and washdown.

Match flow rate to the task — dust suppression over a large area needs considerably more flow than filling troughs.

Drain it fully when not in use, including pumps, hoses and outlet valves where water sits and freezes first. Insulated covers help on static units.

A frozen and expanded outlet valve is the most common winter failure and is usually more expensive to fix than draining would have been to do.

Keep it sealed, keep light out to discourage algae, and empty and rinse between uses rather than leaving standing water for weeks. Fit an insect-proof vent.

For livestock use, periodic cleaning matters more than people expect — biofilm in a bowser affects palatability and intake.
