Water Bores Assessments
In 2016 Havelock North in New Zealand suffered one of the worst potable water contaminations through campylobacter, in the western world. Over 5,500 of the town’s 14,000 residents were affected with three deaths linked to the contamination. A groundwater bore was contaminated by sheep faeces. A large portion of New Zealand’s drinking water is from underground sources. The bore infrastructure across the country is old and requires constant inspection, maintenance and repair. RDCL has conducted multiple bore scanning services across Hawke’s Bay, Western Bay of Plenty and Wellington.
RDCL has specialised design wireline geophysics tools, which are lowered into active/inactive water bores conducting condition assessments of the asset. We deliver 3D digital datasets of the internal structures of water bores and record defects, fractures, apparent metal loss and fluid temperature/conductivity measurements. Typically RDCL can scan 1-2 bores in a single day, depending on site access and in-ground conditions.
RDCL offers the widest range of optical and acoustic scanners and cameras across New Zealand, which allows extremely detailed imagery in 3D of bores. These datasets are far more accurate than conventional CCTV systems. RDCL can measure and record defects and assess if water ingress has occurred at identified features. RDCL scanning equipment allows reliable, repeatable datasets so future condition monitoring assessments can easily refer to previous datasets.
