As the successful tenderer J&S drilling was awarded these important works by the West Australian Water Corporation to replace 5 existing Production Bores along with the decommissioning of 5 redundant bores.
Works were completed adjacent National Parks requiring 4WD access along bushland tracks, equipment wash down for weed and seed and dieback control.
Bore casing diameters ranged from 250mm to 200mm comprising steel surface casing, PVC casing and Stainless Steel screens installed at varying intervals.
Depths of up 80 metres were successfully drilled and installed.
All bores were air developed for 40 hours to remove drilling muds and fine sands to ensure the quality and integrity of the water supply.
Pump testing, through step and constant rate testing was completed with flow rates of up to 30 litres per second.
As lead contractor J&S drilling was responsible for holding a Construction Risk Assessment Workshop (CRAW) prior to commencement, subcontractor selection and prequalification, program scheduling and reporting.
Licenced Class 2 drillers and accredited crews completed the project on time and within budget.
