Brown Bros (NZ) Ltd specialises in large capacity water supply bores, de-watering bores, injection and re-injection bores to suit various geology types, depths and end user requirements. We have drilled the deepest water bore in New Zealand, at just over 1000 metres deep.
With over 65 years of experience, Brown Bros (NZ) Ltd are leaders in water bore design, testing and development.
Brown Bros (NZ) Ltd have designed and drilled in all types of geology, from large capacity town supply, irrigation and industrial water bores, to smaller water bores as required for farms, lifestyle blocks and private landowners. We can complete your entire project from pilot holes, drilling and construction, development, submersible pump installation and pump testing.
Bore rejuvenation
We believe our bore rejuvenation procedures are the most efficient in the industry. On some older production water bores we have had increases in the available water volume of up to 46%, with corresponding reductions in pumping and energy costs.
Water bores and de-watering bores
A water bore is an underground structure that extracts water from the ground for supply purposes.
There are two basic bore designs, 'open hole' and 'screened bore'. Geology is the main factor that determines which sort of bore is most suitable for a particular site. Open hole bores are usually constructed in rock geology, and screened bores are required more often in sand geology to restrict sediments entering the bore.
De-watering bores are similar to water bores, although their purpose is to extract groundwater in order to reduce the water level in a mine or quarry site.
Injection and re-injection bores
Injection and re-injection bores are the reverse of a water supply bore - they are used to recharge or dispose of clean water back into the ground. For example, re-injection bores are used to send spent warm geothermal water back into the hot geothermal aquifer.
