Rain drains One.

 The outside of the house is leveled up and a perforated pipe is put in at the house boundary, backfilled with 20mm rejects and then covered with Teram (geotextile membrane) to create a land drain or “French Drain” to help keep the lawn dry in heavy rains. This will be hooked up to the rain water drain and then fed into our next bit of fun, a rainwater recovery system for toilet and washing machine use.
