About Prosep
Hands-on specialists since 1998.
Prosep was founded on a simple principle: industrial clients don't just need chemicals delivered — they need reliable on-site engineering that protects their assets and keeps their plants running.
Our story

We work alongside your team as hands-on specialists and problem-solvers, focused on measurable results in uptime, efficiency, and compliance. Our engineers don't drop off drums and disappear — they sample, dose, monitor, report, and come back.

SANS 241 potable water
Potable water purification and disinfection programmes managed against the SANS 241 drinking water quality standard.
SANS 893 Legionella control

OHS Act on-site safety
On-site work conducted under the Occupational Health and Safety Act, integrated with your site’s safety systems.
Put 25+ years of plant-floor engineering on your side.
Talk to the team that treats water where it actually matters — at the boiler, the cooling tower, the membrane, and the discharge point.
