A pig launch and recovery apparatus independently mountable to and removable from a water supply system including at least one water main and valve. The pig launch and recovery apparatus comprises a flow tube and a launch and recovery tube. The flow tube includes first and second flow ends and a main flow valve located between the first and second flow ends. The first flow end is removably mounted to a recirculating unit including a pump. The second flow end is removably mounted to a first point in the system. A launch and recovery tube further includes first and second launch ends, wherein the first launch end is fluidly connected to the flow tube between the first flow end and the main flow valve, and wherein the second launch end is fluidly connected to the flow tube between the main flow valve and the second flow end.

A nozzle is provided for cleaning the interior of pipes that is capable of cutting through obstructions disposed in the interior of pipes. The nozzle comprises a three-dimensional (3-D) fluid mechanics comprising a 3-D redirection configuration that redirects high-pressure fluid received in the nozzle from a fluid source onto multiple pathways, or channels, toward rearwardly-facing jet outlets. The 3-D fluid redirection configuration redirects the water in a manner that reduces or eliminates vibrations in the nozzle that can degrade performance and cause other problems.

A conduit inspection tool system includes a conduit inspection tool that includes a body that includes one or more wheels configured to move the body through and in contact with a conduit; at least two power generating sub-systems coupled to the body, each of the at least two power generating sub-systems configured to generate electrical power to operate the one or more wheels to move the body through and in contact with the conduit; and at least one energy storage device electrically coupled to the at least two power generating sub-systems, the at least one energy storage device configured to store electrical power generated by the at least two power generating sub-systems; and a control system communicably coupled to the at least two power generating sub-systems and the at least one energy storage device.

A method and system having nozzle for cleaning the interior of a pipe is provided. The nozzle has a rinsing fluid inlet and a plurality of rinsing fluid discharges, wherein each of the rinsing fluid discharges is arranged for discharging fluid substantially in a rearward direction. The nozzle has a plurality of rinsing fluid outlets for discharging rinsing fluid substantially in the rearward direction. Each of the rinsing fluid outlets is enclosed by a tube forming a passage between the tube and the rinsing fluid outlet. Each tube is connected to a material suction inlet and comprises a tube outlet for discharging a mixture of material and rinsing fluid.

Systems, methods, and apparatus for tracking location of an inspection robot are disclosed. An example apparatus for tracking inspection data may include an inspection chassis having a plurality of inspection sensors configured to interrogate an inspection surface, a first drive module and a second drive module, both coupled to the inspection chassis. The first and second drive module may each include a passive encoder wheel and a non-contact sensor positioned in proximity to the passive encoder wheel, wherein the non-contact sensor provides a movement value corresponding to the first passive encoder wheel. An inspection position circuit may determine a relative position of the inspection chassis in response to the movement values from the first and second drive modules.

An inspection robot incudes a robot body, at least two sensors, a drive module, a stability assist device and an actuator. The at least two sensors are positioned to interrogate an inspection surface and are communicatively coupled to the robot body. The drive module includes at least two wheels that engage the inspection surface. The drive module is coupled to the robot body. The stability assist device is coupled to at least one of the robot body or the drive module. The actuator is coupled to the stability assist device at a first end, and coupled to one of the drive module or the robot body at a second end. The actuator is structured to selectively move the stability assist device between a first position and a second position. The first position includes a stored position. The second position includes a deployed position.

A multidirectional wheel for traversing a surface is provided that includes a magnet and a plurality of rollers disposed around an outer periphery of each of the hubs of the wheels. The rollers are mounted for rotation in a second axial direction that is perpendicular to a first axial direction of the wheel. The rollers are supported by a plurality of magnetically-inducible brackets attached to the hub. The brackets are optimally sized and shaped to reduce the space between the magnetized materials of the wheel and the surface upon which the wheel travels.

A cleaning vehicle generally has a grey water reservoir having a pre-filter; an aspiration conduit leading into the grey water reservoir upstream from the pre-filter and a vacuum pump adapted to create a vacuum inside the grey water reservoir to draw grey water; a vortex separation subsystem connected downstream from the pre-filter; a filtration bag subsystem connected downstream from the vortex separation subsystem; a filtrate reservoir connected downstream from the filtration bag subsystem; a high pressure hose having an end connected downstream from the filtrate reservoir and another end having a high pressure spray nozzle; a filtrate path extending from the grey water reservoir to the high pressure spray nozzle via the pre-filter, the vortex separation subsystem, the filtration bag subsystem and the high pressure hose; and at least one pump adapted to entrain a flow of fluid along the filtrate path.

A jetter system for removing debris such as leaves, branches, mud, and trash from sewer pipes and from other types of pipes is disclosed. The jetter includes a rechargeable battery that provides direct current (DC), a DC/AC converter, and an AC motor that drives a water pump, or the like means for improved powering and debris removal.
