Septic Tank & Treatment Plant System Upgrades
If your septic tank or treatment plant is struggling to cope, you don’t always need to wait for a failure to take action. A planned system upgrade can improve performance, reduce odours and call-outs, and help you stay compliant — especially on commercial and hospitality sites where downtime isn’t an option.
ICE Drainage provides septic tank and treatment plant system upgrades across London and the Home Counties, supporting facilities management teams, hospitality operators, and commercial property owners.
To discuss an upgrade or site assessment, call 0203 870 1067 or email contactus@icedrainage.co.uk.

When Should You Upgrade a Septic Tank or Treatment Plant?
Upgrades are usually triggered by one of three things: capacity, performance, or compliance risk.
Common signs you may need an upgrade include:
- Persistent odours or complaints near the system or discharge point
- Poor effluent quality (discolouration, solids, ponding, nuisance issues)
- Repeat alarms (where a treatment plant/pumped system is installed)
- More frequent emptying/pump-outs than you’d expect
- Slow drainage or recurring internal plumbing issues
- Evidence the system is undersized for current usage
- Change of use (more bedrooms, more covers, longer opening hours, new kitchens/toilets)
- Ageing equipment and unreliable components
If you’re unsure what’s driving the problem, call 0203 870 1067 — we’ll help you diagnose it and plan the right next step.

What Does “System Upgrade” Actually Mean?
A system upgrade can be anything from improving key components through to replacing an outdated setup with a more suitable solution.
Typical upgrade scopes include:
Capacity and performance upgrades
- Upsizing where the current system can’t handle peak demand
- Improving flow management to reduce surcharge and back-up risk
Mechanical and controls upgrades (treatment plants / pumped systems)
- Pump replacement or duty/standby resilience improvements
- Float switch and level control improvements to reduce snagging and false alarms
- Control panel repairs/replacement and safer, more reliable operation
- High-level alarm installation or upgrades
Effluent quality improvements
- Addressing issues that impact treatment performance
- Reducing solids carryover and protecting the drainage field
Drainage field / soakaway upgrades
- Repairs or replacement where the field is saturated, undersized, or failing
- Improvements to distribution and infiltration performance
We’ll recommend the most cost-effective route based on what your system is doing today — and what it needs to do reliably.
Our Upgrade Process (Commercial-Focused)
We keep upgrades practical, planned, and aligned with operational reality.
1) Site assessment & system review
We’ll establish:
- What system you have (septic tank vs package treatment plant)
- Current usage, peak loads, and any recent changes
- Service history and any recurring issues
- Symptoms at the discharge point and drainage field
2) Identify root causes
We’ll look for the real drivers of failure risk, such as:
- Overloading
- Poor maintenance and sludge management
- Mechanical faults (pumps, blowers, floats)
- Restrictions or backflow symptoms
- Drainage field saturation or damage
3) Upgrade recommendations
You’ll get clear options split into:
- Immediate fixes (to stabilise risk)
- Planned upgrades (to prevent repeat issues)
4) Installation / implementation
Where required, we’ll carry out the agreed works and provide a clear handover.
