In February 2004 Quarry Management reported on a system capable of achieving accelerated moisture reduction in sand stockpiles, reducing gravity drainage times from a period of days or weeks to a matter of hours, and significantly reducing the costs associated with force drying material in kilns, dryers or oil-fired furnaces.
The patented system is the creation of geotechnical consultant and dewatering expert Len McGarry, founder of Congleton-based Moisture Reduction Systems Co. Ltd, who first devised the concept several years ago during his time as managing director and chief executive of his former company, Groundwater Control Ltd.
Moisture Reduction Systems’ subsequent research and development work on accelerated vacuum-assisted drainage has culminated in the production of a

cost-effective moisture-reduction pumping system, which is now available in the form of a complete design and installation service package that can be tailored to suit most material producers’ requirements.
One of the latest companies to benefit from such a system is Norman Emerson & Sons Ltd, a family run sand and gravel business based in Derryadd, near Lurgan. Their system — the first of its kind in Northern Ireland — has been installed at the company’s Ardmore sand quay on the shores of Lough Neagh, where, according to general manager Colin Emerson, it has quite literally ‘transformed’ the company’s operations.
Emerson’s system was designed to alleviate serious site drainage problems being caused by run-off from their six Linatex cyclone sand stockpiles.
