Maintenance is conducted yearly by a certified technician from Morgan Plumbing. Every year the driplines need to be flushed and periodically this needs to be done with chlorine to remove algae and other biomatter from the driplines. In previous years the flush procedure has been conducted sporadically due to the absence of electricity to power the pump when Morgan Plumbing have visited Umukuri.
Here is the chlorine flush procedure, which should only be conducted by certified personnel. 13% Chlorine solution is used and the procedure is conducted twice.
