Rainman - Rainwater Harvesting System Brochure

Excavation
The excavator must be on site on the morning of the delivery of the system. The client must indicate the level of the inlet pipe at the hole if pipe not provided. If ground conditions are dry the hole can be dug before technician arrival, however if conditions are wet, the hole should only be excavated through the dry material and not below until the installer arrives. The client must have adequately sized rock breaking equipment where required. All excavation is the responsibility of the client.

NB. In cases where the soil conditions are wet or rocky, it is recommended to make a 400mm hardcore bed to stand tank. Also note that if it is a high water table area, it is recommended to fill tank with water to prevent buoyancy.
