per year. Here's how they do it:

Pitch Makeup

At ground level the drainage system installed is connected to huge suction fans which allow us to blow air through the pitch and suck water out. These pipes are covered with a 300 mm layer of permeable pebble stone which has a drainage rate of about 900 mm per hour. Over this a carefully selected Wexford sand forms the lower rootzone into which the undersoil heating system is installed. The undersoil heating system works on a series of hot water pipes transferring heat to the sand rootzone. The sand continues to a depth of 260 mm with a specialist fibre stabilising agent tilled into the sand to keep the surface stable. On top of this is a 40 mm specialist sod which is a 100% natural sandy loam soil. The sward is 90% perennial ryegrass and 10% fescue.
