What we build

Two infrastructure disciplines. One EPC team.

Civil, mechanical, electrical, process, control and instrumentation engineers working from the same head office in Gauteng — carrying a project from feasibility layout through construction and commissioning.

01 — Energy

Grid-scale solar & BESS

Utility-scale PV plant design and construction, sub-frame and module installation, electrical single-line design, cable trench and MV works, and containerised battery energy storage integration.

View energy capability →
02 — Water

Water & wastewater treatment

Potable water treatment, municipal and industrial wastewater treatment, desalination and ceramic silicon-carbide membrane filtration — from containerised skids to multi-megalitre plants.

Potable water (WTP)

Municipal and rural drinking water treatment from borehole, surface or municipal feed water.

/ 02

Wastewater treatment (WWT)

Municipal and industrial effluent treatment, including COD reduction for process water reuse.

/ 03

Desalination

Full EPC desalination plants and pre-treatment ahead of reverse osmosis for brackish and seawater sources.

/ 04

Decentralised supply

Containerised, plug-and-play, tap-to-pay water dispensing units requiring no external power.

Ceramic membrane technology

Silicon carbide (SiC) ceramic membranes — a shorter, harder-working path to clean water

EPF Systems represents advanced ceramic microfiltration and ultrafiltration membrane technology in Southern Africa: a 0.1-micron mechanical barrier that removes bacteria, algae and suspended solids without chemical or oxygen balancing, and can be backwashed hard without damaging the membrane.
