 | Prepare hole. Ensure that the surrounding soil left in the walls of the hole is solid, leaving a 150mm - 200mm (6-8") gap to allow positioning of tanks and backfilling with sand. (If there is major water seepage into the hole from the surrounding soil this site will not be suitable.) |  |
| | A base of 50-70mm (2-3") of sand or crusher dust must be put in the hole and compacted. |
 | Tank must be lowered into the hole squarely by crane (Crane hire at purchaser's expense.) Tank must then be filled with water above ground height, then back filled with bedding sand. Note: It is important that tank be buried into ground to only half of it's wall height. |
 | Water Inlet - it is recommended that water be directed into tank through strainer. Fixed inlets must be supported and have flexible hose fitted (See plumbing instructions) |
 | Water Outlet - Plumbing - Connect your outlet pick up. (It is recommended that the outlet comes through the tank roof.) Flexible hose 300mm (12") in length must be placed between the valve and other plumbing. |
 | Important: Water volume of the inlet must equal water volume of the overflow. Eg 2 x 100mm (4") inlets = same capacity overflow. |
 | Water Outlet - Overflow - Connect overflow. Water must be piped away from tank. |
