Servicing and Maintenance
Regular servicing of your well protects your water supply. Baylis Brothers can maintain your well and help you to identify and repair any problems.
Baylis Brothers
Baylis Brothers offers a range of services to keep your bore producing the quality and quantity of water your property requires. Then, if you no longer require a bore we are able to decommission it safely for you, meeting the requirements of your local council.
Camera Inspections
Our state of the art camera equipment takes the guesswork out of maintaining your well or fixing problems. We’ll recommend using a camera in your well: if we identify a problem; after ground movement caused by an earthquake; or if you’re maintaining a municipal bore.
TECHNICAL SPECIFICATIONS
- High Resolution colour camera
- Capability to view to 500 metres
- Inspect casing integrity; build up of biofilm & corrosion
- Inspection of well screens
Re-developing
If the performance of your well has declined, or your bore has a problem, call Baylis Brothers. We’ll work out exactly what’s going on, and, depending on the type of bore you have, we can choose from a range of options to improve the condition of your well. If needed, we can use our state of the art camera equipment to diagnose which technique is going to deliver the best results.
If your bore is suffering from build up we can use Boreclean to remove bacteria and calcium, or heavy duty brushes to scrub the lining of your bore and remove build-up. We can also use high pressure air to redevelop your bore and restore the flow of water.
TECHNICAL SPECIFICATIONS
- Utilises high pressure air through blowpipes
- Pressure cleans debris from the bore
- Opens up the aquifer through the well screen system
Bailing and Slurping
Your bore may need specialist help to restore it to full functionality. Once we have assessed its condition we will be able to suggest the best way forward.
The team at Baylis Brothers are experts in diagnosing what’s wrong with your well and implementing the right solution. Depending on the type of bore hole you have and the condition that we assess it to be in, we’ll choose the right equipment to deliver the best results.
If your bore or well needs to be cleared, we may identify the need to bring in baling or slurping equipment.
Baling is when you suck the sand out a bore very gently using a baling bucket.
Slurping uses air to suck all the debris out of your bore hole.
Baling utilises a baling bucket/sand pump to remove debris from the base of the bore.
Slurping uses a venturi system, air operated that sucks from the base of the bore, acting like a vacuum cleaner and allows for the removal of fine sediment and discoloured water from the bore in large volumes quickly.
Pressure Testing
Holes in the casing of your bore have the potential to compromise your bore security and contaminate your water supply. If your bore security is in question, we can use pressure testing equipment to assess the condition of your bore.
Purchasing a new property?
We recommend pressure testing all bores prior to purchase, to help you to assess the condition of the bore and bore security. This can be an important step to help you to understand the quality of your water supply and whether contamination could occur.
TECHNICAL INFO
Pressure uses a USA made inflatable packer on a custom mandrill. This inflates into the bore sealing it and in combination with a sealed wellhead pressure is then introduced into the bore to check for casing leaks. If it does not hold pressure then there is a leak in the casing. This depth is recorded and checked with the camera for signs of a visual leak.
Gland Testing
Baylis Brothers are experts in Bore Security and can help you to ensure your water supply is safe from contamination. Municipal bores and irrigation bores (and occasionally domestic bores) that operate with submersible pumps can be gland tested to ensure that no contamination is occurring from the top of the bore to the water supply.
TECHNICAL INFO
There are three stages to Gland Testing:
- A visual inspection of the glands and cabling
- A physical wipe of the cabling and tugging to see how tight the cabling is in the gland
- Pressurising of the bore through the sealed wellhead using compressed air
By simply spraying the glands/cabling with a soapy solution you get visual proof if there is a leak, just look for soap bubbles.
Bore Decommissioning
Is your bore old, insecure or simply no longer in use? If you no longer use your bore, it’s important that it is completely decommissioned and sealed.
Let us take the hard work out of decommissioning your bore.
Baylis Brothers can manage the entire process of decommissioning your bore to the satisfaction of your local council. We can complete your application form and provide supporting photography and GPS references, then submit all the required paperwork to the local council.
TECHNICAL INFO
Used as a means to decommission old, damaged or unused bores.
Artesian bores are grouted using a pressure pump system, either with a cement or Bentonite mix depending on requirements.
Non artesian bores can be pressure grouted or backfilled with Bentonite pellets and capped with cement.
With either method it is usual practice to cut of the sealed bore pipe underground so it cannot be disturbed.
Bore security
Is your bore safe from contamination? Protect your well or bore with bore security that you can trust, and meet council requirements at the same time.
If you would like to find out more about bore security and whether your bore is secure, get in touch today for an obligation free quote or a chat.
Whether your bore is new or old, it’s important that it is water tight in both directions in order to prevent contamination of your water supply.
Baylis Brothers are experts in drilling bores and completing the project with excellent bore security. We use state of the art equipment and techniques to test that your well is water-tight, and there is no contamination from the external environment or the glands or fittings. We then ensure that your well meets council requirements by following guidelines to ensure that your well is properly protected and secure.
TECHNICAL CONSIDERATIONS
After the Havelock North Water Contamination event there is now a greater understanding of the need for bore and aquifer security. Works included for this would be bore casing a minimum height above ground level; the bore casing, wellhead and fittings in good condition. Either Bentonite or concrete placed around the bore at surface level to provide a seal between the casing and ground, hopefully help mitigating possible contamination ingressing down the side of the casing pipe. Non return valves fitted to bore droppers and pipework to stop possible back-flow and where required the bore fenced off to stop access by stock or the public.
