New Production Bore Culcairn

⁠⁠⁠The purpose of this project is to drill a new groundwater production bore for the Culcairn Town Water Supply.

The Greater Hume Shire Council recently authorised a drilling contractor to drill a series of test holes to determine aquifers, yield and water quality. Out of the three (3) holes drilled the third test hole was selected for the new groundwater borehole. Two aquifers were intersected at 77-81m and 83-84m. Yield predicated is between 25 to 35 L/s. Water quality is within the ADWGL.

The project requirements include;

* Drill and ream a 450mm diameter borehole to a depth of 85.5 metres
* Supply and install 79.5 metres x 250mm schedule 10/316 stainless steel casing, centralisers, stainless steel bottom cap and associated works
* Supply and install 250 mm diameter stainless steel screens in two aquifers, at 77 - 81m and 83 - 84.5m and associated work.

Other work included is the development of bore, gravel packing, grouting, pump testing, water sampling analysis, pump test analysis report including yield, draw-down & recovery data and final borehole construction details.
