Legal Requirements

Prior to installation, there is a legal requirement to obtain permission from the appropriate agencies (including connection to a public sewer).

Delivery & Installation

Units are normally delivered by flat bed vehicle and cranage facilities should be available on-site for off loading. Installation is quick and economical, the unit requiring only a concrete base and surround. Comprehensive installation instructions are supplied with every unit.


24hr Storage to Meet Building Regulations

The Klargester HillMaster24 pump station range has been designed in accordance with Building Regulations Document H1 Foul Drainage, page 16. (Pumping Installations) Section 2.39. This states:

"Where foul drainage from a building is to be pumped, the effluent receiving chamber
should be sized to contain 24 hour inflow to allow for disruption in service. The minimum daily
discharge of foul drainage should be taken as 150 litres per head per day for domestic use.
For other types of building, the capacity of the receiving chamber should be based on the
calculated daily demand of the water intake for the building. Where only a proportion of the
foul sewage is to be pumped, then the capacity should be based pro-rata. In all pumped
systems the controls should be so arranged to optimise pump operation. The required 150
litres per head per day volume should reflect the storage volume in the station pump or
station and overflow tanks."

Product Range



The HillMaster range offers a competitive solution to the pumping requirements of both domestic and industrial applications. Often it can be preferable to keep civil work and installation costs down to a minimum but such economy should not mean any shortfall in quality.

The Chiltern range is manufactured in tough polyethylene using advanced rotational-moulding technology, while the Pennine, Cairngorm and Mendip ranges are made from maintenance-free GRP. All units are engineered with the highest quality parts and fittings.

  • High-level alarm as standard (optional as marked *)
  • Various invert depths
  • Internal lifting chains and guiderails (as specified)
  • Wide range of pump options including grinders/macerators
  • Pedestrian/vehicle covers



The HillMaster24 range has been specifically designed to meet the requirements of Building Regulations Document H1 Foul Drainage. This regulation recognises the need for pump stations to have a 24hr storage capacity in case of a disruption in service (such as a power failure).

This comprehensive range offers an advanced solution to larger domestic and industrial applications. For large-capacity flows (such as stormwater run-off from hard-standing areas), horizontal holding chambers are available in a comprehensive range of sizes.

  • High-level alarm fitted as standard
  • Various invert depths
  • Internal lifting chains and guiderails fitted as standard
  • Wide range of pump options including grinders/macerators
  • Combined chamber capacity up to 90,000 litres
  • Pumping distances up to 1000 metres
  • Pedestrian/vehicle covers


Effluent Pumpsets

A septic tank or treatment system pumpset can be used to disperse settled effluent when a site has a high water table or adverse invert levels. Installed after the septic tank or treatment system and pumping settled effluent up to an inspection chamber, flow to the drainage system then takes place by gravity in the normal way.

Effluent Pumpsets

Domestic Sewage Pumpsets

If the main sewer is accessible but at a higher level to (or some distance from) the domestic foul drain, then a domestic sewage pumpset may be used to pump unsettled sewage directly to the main. Whilst single pump units are acceptable for individual houses, it is recommended that twin pumping systems be used for multiple dwellings.

Effluent Pumpsets


Surface Water Pumpsets

Due to the amount of rainwater that can fall in a short time period, Surface Water run-off is often the most demanding of all applications, whether hard-standing or roof areas.

Klargester offers a comprehensive range of packaged pump systems in both standard form or manufactured to bespoke specifications. Careful calculation of the run-off areas is essential when sizing these pump systems.
