Do you have a borehole pump breakdown? Call us now on 01460 68167 for our 24 hour 7 day a week emergency call out service.

Our specialist engineers have years of experience in borehole pump repairs. We can repair any type of borehole pump including the following:

  • Calpeda
  • Dab
  • Flygt
  • Grundfos
  • Wilo
  • TT Pumps
  • Xylem
  • Pedrollo
  • Zenit
  • Lowara

We are often called to site to investigate failed or poorly performing boreholes.  Problems can be caused by many different issues such as borehole design, cable, pipe or non-return valve failure, outdated or faulty installation and indeed failure due to the pump ceasing to operate due to old age.

 

Somerset Pumps will attend site free of charge and provide a report with recommendations detailing the required action to get the well working correctly again.  Depending on the results of the site visit this can involve the cleaning of the well using an air compressor - to the supply of a new pump and cable, updating the electrical installation, new pipework or updating the headworks.   

 

Using details that may be available from the original installation, and with reference to the application requirements we are able to source replacement pump units from all major manufacturers such as Grundfos, Lowara, Dab,  Pedrollo or Godwin.

 

The report would also include any recommendations regarding improvements and updating.   We often find that existing borehole headworks do not comply with current risk analyses carried out by local councils.  Many do not have sufficient protection from ground water flooding or contamination from vermin.  Somerset Pumps can undertake the necessary work to resolve these issues.

 

The following details extracts from DWI (Drinking Water Inspectorate) and Local Council Guidance Notes

 

 A private water supply is a supply of water which does not come from a public water supply (from a water company unless it is subsequently supplied by someone else). Private supplies may come from a variety of sources, including wells, springs, boreholes and streams.

 

Regulations on private water supplies in England and Wales were introduced in 1991 and were replaced by new Regulations introduced early in 2010. The new Regulations apply to all who own or use a private water supply. The new Regulations have been introduced to ensure that water from private supplies is wholesome, so that people who drink water or consume food or drinks made from private supplies may do so without risk to their health.

 

Local authorities are responsible for regulating private water supplies used for domestic purposes (such as drinking, cooking, and washing) in both domestic and commercial premises.

 

Local authority staff will implement the Regulations, do the testing and give you the results. The changes in the Regulations mean that these staff also need to carry out a risk assessment of your private water supply, from the source to the tap. This risk assessment looks at the source of the supply and the surrounding area to see if contamination is possible. It also involves checks of the storage tanks, any treatment systems and the pipework. The risk assessment identifies actual and potential hazards that may affect the health of those drinking the water, so that you can take action to make sure your water supply is safe to drink. Where the water is found to be unsafe, the local authority must ensure that the supply is improved by the owners or people who control the supply. 

If the house you and your family live in is the only property supplied by a water source, and only your family drink the water, the local authority will not carry out a risk assessment unless you ask them. They can charge for this service.

 

The borehole needs to be protected from the ingress of surface flows (such as flooding). This can be accomplished in a variety of ways such as having a ditch surrounding the borehole with an impermeable lining and a suitable discharge downslope from the borehole conveying surface water away from the immediate vicinity of the borehole. It should be borne in mind that surface flows, while including flooding, are not restricted to flooding. In certain ground conditions the impermeable nature of the soil during periods of dry weather will produce a surface akin to concrete which will result in rainfall, e.g. a heavy summer downpour, running over the surface rather than percolating into the soil. Such conditions need to be protected against by use of appropriately engineered borehole arrangements.

A properly constructed and well-fitting cover is essential to maintaining the integrity of the source. In addition boreholes require a properly constructed and maintained chamber around the headworks with an inspection cover. The borehole/well casing should extend at least 150mm above the level of the floor and there should be a concrete apron, sloping away from the top of the borehole to ensure that any ingress to the housing will always run away from the top of the borehole. Covers should be of a suitable non degradable material, watertight to prevent ingress of rainwater, vermin-proof to prevent animals from entering the well (i.e. with no holes through which small mammals can enter), and lockable to prevent malicious (or curious) persons gaining access to the supply. Points of cable/wiring entry should have water tight seals.  If ventilation is present ensure that it is also vermin-proof with appropriate wire mesh in place.

If the headworks are in an unsatisfactory state-of-repair then there is an increased risk of vermin entering or of surface flows inundating the structure. If there is evidence that the headworks are in an unsatisfactory state-of-repair then the likelihood will be that it will fail the risk analysis.
