Executive project brief
The challenge
Two student residences generated significant greywater volumes while the university faced rising municipal tariffs and growing pressure to improve water security.
Hydraulic duty64 KLPD greywater treatment plant
Water streamWater
Operating contextEducation and student accommodation
Required destinationToilet flushing and sports-field irrigation
Solution architecture
The following elements are documented in SewTreat’s published project record.
- Turnkey 64 KLPD greywater treatment facility
- Plumbing retrofits to redirect treated water to toilets
- Civil and distribution infrastructure
- Irrigation integration with municipal top-up for continuity
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: R1.5 million annual saving.
