A vacuum truck for dispensing water into a sewer or similar location and receiving recovered water from the sewer that includes debris to be removed therefrom. The vacuum truck includes a debris tank that receives the recovered water and retains debris removed from the recovered water. A primary and a secondary filter are positioned in the debris tank for separating debris from the recovered water. A water pump draws the recovered water through the secondary filter and provides the water to a tertiary filter that removes smaller debris from the recovered water. The recovered water from the tertiary filter is provided directly to a jetting water pump without being accumulated in a water holding tank. The vacuum truck includes a water storage tank that includes potable water for cleaning the truck or when recovered water is not available from the debris tank.

A hose reel arrangement for sewer jetting includes a reel; a hose wound around the reel; a reel frame holding the reel; and a cover arrangement. The reel frame with the reel is rotatable about a frame axis perpendicular to a horizontal mounting surface. The cover arrangement is over a majority of the reel and reel frame. The cover arrangement is selectively movable to expose a portion of the reel to provide access to the hose. The cover arrangement is fixed in position relative to the rotatable reel frame and reel.

An apparatus for cleaning waste collection systems of solid materials. The apparatus is capable of cleaning waste systems in two known ways. First, a pumping method uses normal and injected water flow to suspend the solids in a slurry. A submersible pump moves the slurry from a collection point up to a pressurized container where the water content of the slurry is decanted and reused as injection water while the particulate material settles to the bottom of the pressurized container. Second, a vacuum system may be used to move the slurry from the waste system to the waste container. The vacuum system creates a negative pressure differential, causing material to be pulled through a vacuum tube and into the waste container. When the container becomes substantially full of solid particles, it may be emptied at a dumpsite.

A tank assembly (1) is mountable on a tank truck for the collection of waste material from a portable chemical toilet and for the maintenance thereof includes an outer rigid housing (10) and an inner tank (14) enclosed in the housing (10) and provided with waste material loading nozzles (18, 19) and waste material discharge nozzles (17). The outer housing (10) includes an inner wall (31, 32) having a surface which is complementary and substantially mating and closely contacting the surface of the inner tank (14). The outer housing (10) and the inner tank (14) are made of plastic material. The inner tank (14) has a substantially spherical shape. The tank assembly (1) is light-weight, of low production cost and does not have corrosion problems.

A sewer cleaning device and/or street cleaning device includes a dirt removal container for receiving and transporting mineral dirt residues accumulating during sewer and/or street cleaning. A removal device for clearing out the dirt removal container includes a conveying worm arrangement received on a swivel frame which is swivel-mounted on an axis extending in a longitudinal direction of the container and swivellable by a swivel drive. The conveying worm arrangement is sideways deflectable by the swivel frame relative to a center position associated with the container bottom on both sides along the container wall and a fast discharge of the dirt removal container can be achieved by two conveying worms arranged in symmetrical position relative to a central longitudinal axis of the swivel frame, the conveying worms limiting a gap therebetween and acting together for the transport of the bulk material along the inner side of the container wall.

An example system includes an auger assembly that is attachable to a vacuum system, in which the auger assembly includes a hose, an auger, and an auger motor. The hose includes an inlet at a distal end and an outlet at a proximal end. The auger includes a shaftless helical blade having a portion that is radially enveloped by the hose. The vacuum system is adapted to suck material from the septic tank or pit latrine via the hose. The auger motor is adapted to rotate the auger about a helical axis in a first direction, in which the rotation about the helical axis in the first direction causes the shaftless helical blade of the auger to translate along the helical axis from the outlet of the hose towards the inlet of the hose.
