The Questioning Engineer is glad to team up with Water New Zealand to produce this important training course for the New Zealand water industry.

Critical Control Points in Water Supplies

Do you know what the critical control points are in your water supply? Do you know what critical limits work for your system? (Hint: “typical” critical limits don’t apply to every system!)

Use Critical Control Points to feel confident you are always supplying safe water.

We know how, and we’re ready to share.


I used it to explain the concept to WTP operators as some of our water safety plans were up for review. We workshopped the principles, which was good. The operators grasped it.

I thought the concepts were presented succinctly and clearly.
