Rustenburg Dorpspruit — Emergency spill response
The spill required a rapid response into flowing water to bring bacterial contamination down before it caused further downstream impact.

Project overview
Site challenge and treatment summary.
The spill required a rapid response into flowing water to bring bacterial contamination down before it caused further downstream impact.
- Initial problem
- A sewage spill entered a municipal watercourse and needed to be brought under control.
- Baczyme product used
- Baczyme Sewage Liquid+
- Dosage
- 1 litre of Baczyme Sewage Liquid+ was dosed per megalitre daily. A biological treatment response was applied to the affected watercourse.
- Treatment period
- 47 days
Site conditions
What Baczyme was responding to.
- Raw sewage was spilling into a municipal watercourse.
- Response and monitoring ran over 47 days.
Treatment objectives
What the programme aimed to support.
- Respond to an active sewage spill in a municipal watercourse
- Reduce E. coli contamination as quickly as possible
- Bring the site under control within a defined response window
Before and after
Reported project progression.
These notes summarise the before-and-after information available for this specific Baczyme project.
Greater than 99.97% E. coli reduction achieved within 47 days of the spill being reported.
Reported outcomes
Greater than 99.97% E. coli reduction was achieved, bringing the spill under control within 47 days.
Client name confirmation is pending before this case study is published (municipal context — likely fine to name, to be confirmed).
Test results or documents
Emergency spill response result; laboratory verification details for the specific figure were not provided in the source brief beyond the reduction percentage.
Project significance
Why this project matters.
This project demonstrates a rapid biological response to an active municipal sewage spill rather than a planned, ongoing treatment programme.
