Combination Units / Drain Clearance
Combination Units are used when the larger sewers, culverts or gullies require cleaning. These units are efficient in quickly removing silt and general debris. Also, if cleaning is required and a readily accessible source of mains water is not available then the water held in the combination unit itself, is used to give a flow of 65 gallons/minute, for cleaning purposes. The combination unit can collect or remove a variety of solid objects such as bricks, bottles or compacted sewage. A separate tank on the unit allow us to 2,000 gallons of waste water to be removed which is a major advantage where flooding has taken place and sewage and sludge also needs to be quickly removed to avoid damage to property.
