A large fraction of the low pressure domestic bores in Rotorua suffer from calcite scaling. The problem is sometimes so sever, that wells have to be mechanically reamed every six weeks. We have tested the use of threshold antiscalants to control the calcite deposition. The experiment ran for over eight months and there is no sign of any calcite buildup, either in the well or in the surface pipework. Previously, the well had required reaming every three months.
