South West Water (SWW) has been in the news a lot lately, and not for the best reasons. From contamination incidents to illegal sewage spills, the water company has faced a series of problems and prosecutions in 2026. However, one issue that has not received as much attention is the capacity improvement for septic tank waste businesses. In this article, I will explore this topic and provide my personal commentary and analysis.
The Septic Tank Issue
The repeated closure of some waste water treatment works in Cornwall to commercial waste tankers in 2023, 2024, and 2025 has caused a great deal of frustration. The issue had not been so high-profile, but it is a significant problem for the region. In my opinion, this issue is particularly interesting because it highlights the challenges faced by water companies in managing waste water treatment works and the impact of these challenges on local communities.
SWW's Response
SWW has increased capacity at its Hayle treatment plant by 50,000 cubic litres by refurbishing an additional tank. The company has also worked with regulators to increase capacity in busier periods. From my perspective, this response is a positive step towards addressing the issue, but it is not enough to solve the problem completely.
The Broader Implications
The septic tank issue has broader implications for the region. It raises a deeper question about the resilience of water treatment systems in the face of increasing pressure from commercial waste tankers and changing weather patterns. In my opinion, this issue is a symptom of a larger trend towards increasing waste generation and the need for more sustainable waste management practices.
Personal Reflection
As a resident of Cornwall, I have been frustrated by the repeated closures of waste water treatment works. I think it is important for water companies to be transparent and accountable for their actions, and I am pleased to see SWW taking steps to address the issue. However, I also think that there needs to be more focus on sustainable waste management practices and the need for a more resilient approach to waste water treatment.
Conclusion
In conclusion, the septic tank issue is a significant problem for the region, and it highlights the challenges faced by water companies in managing waste water treatment works. While SWW's response is a positive step, it is not enough to solve the problem completely. As a resident of Cornwall, I am hopeful that the company will continue to take steps to address the issue and that there will be a greater focus on sustainable waste management practices in the future.
