Groundhog Slurry Handling


The ‘Groundhog’ range of sludge and slurry handling equipment are manufactured by Pollution control and are world renown as reliable and robust machines that have proven to be the Farmer or Contractor preferred choice over the decades.

We pride ourselves on the build quality, backup and advice we provide our customers.

SLurry handling systems

The Umbilical Application System

The umbilical method of Sludge / Slurry handling involves pumping the slurry liquid from a liquid storage facility (lagoon or tank) using a high-pressure pump unit, via a pipeline, to a tractor-mounted applicator unit.

Therefore, once the system is set up and the pipeline has been laid, the pump is started, and the applicator unit is then driven in straight lines, dragging the supply pipe, known as the Drag Hose, up and down the spreading field.

The umbilical application system has numerous advantages over traditional tanker-based application methods:

  • Increased work rates – 100m3 (20,000 gallons) an hour are typical.
  • Reduction in field soil comp action – No heavy tanker unit is driven onto the field.
  • Eliminates damage to the field access area -Applicator unit is driven In and Out of the field just once.
  • Eliminates mud carriage onto field access roads -Applicator unit stays in the field until the field is finished.

Slurry Application Equipment

Splash Plate Applicator

Groundhog Splash Plate Applicator range allows the operator to surface apply sludge or slurry in a controlled method through the use of low-level, large-bore rubber nozzle units. Due to this, it produces an even, large droplet spread pattern resulting in a drastic reduction in nozzle blockages, odour, and wind drift.

Trailing Hose Applicator

The Groundhog Trailing Hose Applicator range is designed to lay sludges or slurry directly on the ground, therefore reducing nitrogen loss, improving application rate accuracy, and reducing odour and wind drift problems.

Sub-Soil Injection

Groundhog Sub Surface Injectors have been developed over 20 years to give an unrivalled performance on grassland and stubble. As well as this, all machines incorporate a unique slim-line design of injection legs that can achieve injection depth from 4″ to 14″ with easily replaceable surface contact parts. Due to this, injectors are available as Umbilical or Tanker Mounted Units.

The Benefits of Slurry Injection

  • Eliminates the environmental and nuisance problems previously associated with sludge and slurry disposal. Therefore, this can bring more land into use closer to housing and sewage works.
  • Higher application rates and significant transport economies.
  • The un-rivalled nutrient benefit to crops is that no leaching occurs in the atmosphere
  • Even applications with the absolute minimum of surface contamination and none of the surface run-off problems can occur with top-spreading systems.

Lay-Flat Hose Reelers

Our range of Agricultural lay-flat hose Reels is designed to suit the demands of farmers and contractors. Due to this, all Groundhog hose reelers have been developed to give the user unrivalled performance and reliability. Due to this, they are built to the highest standards of our industry-proven designs. As well as this, all reel units feature powerful hydraulic motors, chain reduction drive systems, and a hydraulic pressure relief safety system.

Pump Systems

Groundhog systems can supply either Centrifugal or Progressive Cavity (screw) pump systems. Therefore, centrifugal pumps offer the operator high output over a range of pumping conditions. Whereas, progressive Cavity pumps give the operator complete control over flow and application rates in conditions with high Viscosity slurry, distance and head.

Mobile Holding Tanks

Our range of Mobile Holding tanks is designed to be towed (empty) by a Tractor. Therefore, the single rear axle is equipped with a hydraulic jacking system powered by the towing Tractor to enable the tank to be lowered to the ground for field use. Being that, capacities available are 20m³ to 46m³.


Groundhog supplies the ‘Angus’ brand of polyurethane and rubber hoses specifically designed for drag use.

Tanker Mounted Systems

All umbilical Slurry application equipment is designed to be mounted on Slurry tankers.
