MENUMENU
Not every sewer line is conveniently located along a roadway. Some manholes are tucked behind residential properties, across grassy easements, near golf courses, or in areas where traditional sewer cleaning trucks simply cannot reach.
For municipal maintenance crews and sewer cleaning contractors, these locations create challenges. Moving hoses over long distances, navigating uneven terrain, and protecting surrounding property can turn routine sewer maintenance into a difficult and time-consuming job. In some cases, limited access can even contribute to sewer lines receiving less frequent preventive maintenance.
Sewer Equipment’s easement machines are designed to make those difficult jobs more manageable. By extending the working reach of a sewer jetting truck or trailer by 500 feet or more, these specialized machines help crews access remote manholes while reducing the need to bring large equipment across sensitive property.
With three models available—the JAJ-600WH, JAJ-600SK, and battery-powered JAJ-E—Sewer Equipment offers solutions for a variety of access conditions and maintenance applications.
An easement machine does more than transport a sewer cleaning hose. Its design influences how crews access a jobsite, maneuver around obstacles, protect surrounding surfaces, and perform maintenance once they reach the manhole.
Understanding these benefits helps explain why the right easement machine can be a valuable addition to a sewer maintenance fleet.
One of the biggest challenges in sewer maintenance is reaching manholes located away from streets and other accessible work areas.
A sewer jetting truck may have the necessary cleaning power, but getting that truck close enough to the access point isn’t always practical.
Sewer Equipment’s easement machines extend the reach of truck- or trailer-mounted jetting equipment by 500 feet or more, allowing crews to position their primary cleaning equipment in a more accessible location while transporting the hose to a remote manhole.
This is especially useful for sewer lines located:
The benefit is greater access to sewer infrastructure without unnecessarily disrupting the surrounding area.
Accessing a remote sewer line should not create additional restoration work whenever it can be avoided.
Heavy vehicles and repeated equipment movement can damage lawns, landscaped areas, and other sensitive surfaces, particularly when the ground is soft or wet.
Sewer Equipment designed its JAJ-600WH with rubber tracks that distribute the machine’s weight across a larger surface area. The machine operates with ground pressure of approximately four pounds per square inch, comparable to the standards used for golf course maintenance equipment.
The battery-powered JAJ-E also operates with less than four pounds per square inch of ground pressure.
By reducing concentrated weight on the ground, these designs help crews navigate maintained properties with less potential for turf damage than heavier equipment.
This is an important consideration when sewer maintenance takes place on residential lawns, recreational properties, or environmentally sensitive sites.
Remote manholes are not always located on smooth, level ground. Maintenance crews may encounter mud, sand, snow, rocks, curbs, slopes, and other obstacles between their equipment and the access point.
The JAJ-600WH uses a Honda V-twin engine and a hydrostatically powered tread drive system. This design eliminates traditional drive chains and sprockets while providing reliable traction and maneuverability.
Unlike conventional wheel-drive arrangements, the machine’s independently suspended rubber track system distributes its weight while maintaining contact with changing ground conditions.
Additional features include skid-style steering with dual joystick controls, allowing operators to maneuver the machine through confined or uneven areas.
The combination of traction, maneuverability, and relatively low ground pressure gives maintenance crews an equipment option specifically designed for the conditions they may encounter along sewer easements.
A sewer easement machine must sometimes meet two competing requirements: fit through a narrow opening and maintain a stable stance when operating on uneven ground.
The JAJ-600WH addresses these challenges with hydraulically extendable tracks.
The tracks can retract to a width of 34 inches, allowing the machine to travel through a standard 36-inch gate. Once beyond the restricted access point, the tracks can extend outward to 46 inches, creating a wider stance for improved lateral stability.
Operators can adjust the track width according to the terrain and available working space.
This combination is particularly useful when crews must move through a residential gate or narrow access route before encountering more challenging ground conditions.
The wider track position provides a stability advantage, although operators must still evaluate slopes, ground conditions, and applicable equipment operating limits before proceeding.
Getting the hose to a remote manhole is only part of the job. Crews must also position and manage the hose efficiently during sewer cleaning operations.
The JAJ-600WH and JAJ-600SK feature a 180-degree rotating safety hose reel.
The reel can be positioned to align with the access point, reducing the need to reposition the entire machine when the manhole is difficult to approach directly.
The rotating design also helps limit unnecessary turning and maneuvering on soft or wet ground.
For additional convenience, an optional automatic level wind system with hydraulic up/down adjustment guides the hose as it returns to the reel. This helps achieve more consistent hose winding while reducing the amount of manual hose handling required.
Features such as these demonstrate how attention to everyday operating challenges can improve the sewer cleaning process.
Difficult access can become a recurring obstacle for municipalities responsible for maintaining extensive sewer networks.
When a manhole is challenging to reach, routine cleaning may require additional planning, personnel, or equipment movement. Those challenges can complicate preventive maintenance schedules.
An easement machine gives crews a practical way to include more remote sections of the sewer system in their cleaning programs.
The JAJ-600WH also features a 5 GPM/10 GPM hydraulic tool circuit capable of powering compatible tools, including bypass pumps and hydraulic saws. This adds versatility when a maintenance operation requires more than hose positioning alone.
By making difficult locations more accessible, easement machines can support more consistent preventive cleaning and help utilities address developing problems before they contribute to blockages or sanitary sewer overflows.
Sewer Equipment offers three easement machine models designed to meet different equipment and operating needs.
The JAJ-600WH is a self-propelled, track-driven easement machine designed for difficult access conditions.
Its Honda V-twin engine, hydrostatic drive, dual joystick controls, and hydraulically extendable rubber tracks provide the maneuverability and stability needed for a variety of off-road applications.
Additional standard features include a safety pressure relief valve, rotating hose reel, variable-speed hose reel control, and hydraulic tool circuit.
The JAJ-600WH is particularly well suited for crews that must navigate narrow gates, uneven ground, and remote access routes.
The JAJ-600SK offers an alternative for municipalities and contractors that already operate compatible skid-steer equipment.
Rather than using a dedicated self-propelled track system, this model mounts to an existing skid steer.
It features a 180-degree rotating safety hose reel, pressure relief valve, and hydraulic hose reel operation. The machine also offers additional hose management options to improve efficiency.
For departments with compatible skid-steer equipment already in their fleet, the JAJ-600SK provides another way to extend sewer jetting capabilities to difficult-to-access locations.
The JAJ-E offers an electric alternative for sewer maintenance crews.
Designed with battery capacity for a typical workday, the JAJ-E charges fully in approximately 12 hours and operates at less than 65 decibels.
Its quiet operation may be especially beneficial in residential neighborhoods, parks, and other areas where equipment noise is an important consideration.
The JAJ-E also operates with less than four pounds per square inch of ground pressure, helping limit disturbance to maintained surfaces.
This model offers another option for municipalities and contractors seeking efficient access to remote sewer infrastructure.
Sewer Equipment’s easement machines combine practical standard equipment with optional features that allow customers to select a configuration suited to their work.
For the JAJ-600WH and JAJ-600SK series, standard equipment includes:
The JAJ-600WH also includes an hour meter, dual joystick skid steering, and a 5 GPM/10 GPM hydraulic tool circuit as standard features.
Specific standard equipment, optional accessories, and hydraulic requirements vary by model. Sewer Equipment representatives can help customers review the available configurations.
Equipment design matters most when it is put to the test in real working conditions.
A large municipality in Missouri, which owns both a Sewer Equipment JAJ-600WH and a competing easement machine, shared its experience with a particularly steep sewer maintenance application.
The municipality specifically selected the JAJ-600WH for the project because of its experience with the machine’s stability on difficult terrain.
The crew explained:
“There is no way it would make it up that hill. It is too top-heavy, and we would have most likely flipped. We actually made sure that the Sewer Equipment easement machine was the only one that was used for this project. I have used the (competitors’) machine in steep applications, and it is a lot more top-heavy, and we actually had to secure the machine with a strap to a truck. With the Sewer Equipment machine, we had no concerns about taking it up that slope.”
This experience illustrates why thoughtful equipment design, weight distribution, and track stability matter when working in challenging sewer easements.
For sewer maintenance crews, these engineering considerations can make a meaningful difference in choosing equipment for difficult access conditions.
With more than 80 years of experience in sewer cleaning and vacuum excavation equipment, Sewer Equipment understands the challenges municipalities and contractors encounter in the field.
From track design and weight distribution to hose management and equipment versatility, the JAJ series reflects an approach to manufacturing focused on practical sewer maintenance applications.
Whether your crews are reaching manholes behind residential properties, navigating challenging terrain, or maintaining sewer lines beyond the reach of conventional equipment, the right easement machine can make those jobs more manageable.
