PAT®
Prescription Athletic Turf®
Natural Field Turf Moisture Management Stats

A PAT® system functions in four different modes:

Subirrigation -- By closing off drainage valves and supplying water back through the matrix, the field can be uniformly irrigated from the base up as water moves through the rootzone by capillary action.

Conservation -- When the rootzone reaches optimum moisture levels, the system can hold those levels for an extended period of time, reducing the amount of overhead irrigation needed and maintaining a favorable air/water ratio in the rootzone. Additionally, when drainage is activated, the system removes only the water in excess of optimum levels. This is particularly valuable in arid, water-restricted areas.

Gravity Drainage -- Under normal operating conditions, excess water is removed from the field by gravity flow. The rate of field drying is governed by how fast gravity can pull water through the sand profile and into the drainage matrix.

Vacuum Drainage -- When water falls on the field faster than gravity can remove it to maintain acceptable moisture levels in the rootzone, the system activates vacuum drainage, and water is forcibly removed at a rate up to three times the natural force of gravity.

The Motz Group is also able to add system features on a site-specific basis. Water recycling can be achieved by capturing and reusing effluent water via storage tanks or retention ponds and then reapplying it through the overhead irrigation system. Various field heating systems can also be installed in conjunction with the PAT® system.
