Where energy and water savings come from
Not less water — the right water in the right place.
Three sources
① Pattern matching: water where it is needed. ② Impact efficiency: same impact at lower pressure or flow (stabilizers, tungsten carbide). ③ Life: fewer replacements and unplanned stops.
How to quantify
Compare before and after with the same measurements: impact distribution, flow, pump current/pressure and water per tonne. Savings without a baseline are just claims.
