Executive project brief
The challenge
Unreliable council supply and borehole water containing turbidity, iron and manganese created a need for an independent treated-water supply.

Water streamWater
Operating contextShopping centre
Required destinationPotable water
Solution architecture
The following elements are documented in SewTreat’s published project record.
- 37 KL raw-water storage
- Containerised AFM, GAC and DMI filtration
- Bag filtration and chlorine disinfection
- 72 KL clean-water storage
- Automated dosing, monitoring and municipal switchover
Engineering assurance
Characterise
Validate the water profile, duty and variability.
Integrate
Define civils, power, controls, storage and existing interfaces.
Operate
Plan access, skills, residuals, consumables and maintenance.
Verify
Agree commissioning, sampling and acceptance evidence.
Published outcome
Published case-study claim: over R1.2 million annual saving and 1.2-year payback.
