There is no 'standard' filtration for all the different systems we install, there are only certain guidelines and regulations across the border.
It always depends on the end use. Our desire and speciality is to conserve water which also means wasting as little water as possible during the filtration/treatment process. If you want potable water, we will provide you with potable water, unless of course your underground water (borehole) is too contaminated for whatever reasons. We do offer a service to have your water samples collected and tested (chemical and bacterial). The appropriate filtration system will then be designed based on the water analysis report. Being in control of your own water quality is indeed a bonus and adds peace of mind.
