OVTS looks after our portaloo clients taking care of scheduled weekly to fortnightly servicing, along with water barrier fills for big events and traffic management sites in Dunedin and even our yard sump cleans. They provide a prompt, efficient service and we would highly recommend them to anyone. Their customer service not only towards myself and the team but also our onsite customers is top notch. They are a great team.

Otago Vacuum tank services did an awesome job delivering 15,000 litres of water for our house supply. Quick, efficient, even delivered late into the day, very clean shiny truck and not a drop of water split. Would highly recommend to others.

OVT were asked to clean out a 20k lt water tank that made our household water smell. The crew were excellent in identifying the problems and engaged with us throughout their work with positive solutions Their two vehicles and equipment looked immaculate in what can be a potentially dirty industry indicating OVT is a very professional company with high standards. I would recommend them to anyone.
