Water bore owners frequently contact AGE Developments in the belief that their bore is corroded out as they are experiencing the production of sand and silt. Often these problems are not occurring due to corrosion or any mechanical damage, but due to bacteria, calcification and mineralised deposit encrustation of the screened apertures.
These deposits have the effect of reducing the open area of the screened section within the bore. Thus to develop the original yield of water through the fouled screens, the water velocity is increased due to the reduced open area available. The increased velocity entrains sand and silts that previously were not present in the pumped water.
High Pressure (HP) Jetting is an effective means of removing heavily encrusted fouling material from within the screened apertures. More importantly however, it also cleans, removes fouling and develops the natural gravel pack and aquifer outside of the screened apertures ensuring a more effective and longer lasting clean out resulting in higher water production yields and lower pumping drawdown levels saving valuable ongoing operating expenditure for the bore owner.
