MATRIX vs Septic Tanks: Why It's Time to Upgrade
For decades, septic tanks were the default choice for off-mains wastewater. They were simple, familiar, and
widely used across rural properties. But times have changed. Stricter environmental regulations, growing
awareness of pollution, and advances in treatment technology mean that septic tanks are no longer fit for
purpose in most situations.
That's where MATRIX sewage treatment systems come in. Built in the UK and certified to BS EN 12566-3.
MATRIX systems deliver safe, clean, and compliant wastewater treatment for homes, businesses, and developments of all sizes.
Here's why MATRIX systems outperform traditional septic tanks in every way:
Septic Tanks No Longer Meet Regulatory Standards
Under the General Binding Rules in England:
- Septic tanks can no longer discharge to surface water.
- Non-compliant systems must be upgraded or replaced.
- MATRIX sewage treatment plants allow legal discharge to both surface water and ground (when correctly
installed).
This makes MATRIX not just the smarter choice - but often the only compliant choice for off-mains drainage.
Cleaner, Safer Discharge
Septic tanks only provide primary settlement. The effluent is still polluted, with high levels of organic matter and suspended solids.
MATRIX systems provide full secondary biological treatment:
- BOD: ~11 mg/l
- Suspended Solids: ~16 mg/l
- Ammoniacal Nitrogen: ~5.9 mg/l
- Treatment Efficiency: ~96.2%
These figures comfortably meet UK discharge consents and align with BS EN 12566-3 requirements.
The result? Crystal-clear effluent that protects rivers, streams, and groundwater.
Environmentally Friendly
Septic tanks are notorious for polluting local ecosystems, especially where soakaways fail.
By contrast, MATRIX systems are:
- Odour-free, minimal and discreet
- Fully compliant under BSEN12566-3
- MATRIX Topas Plus can step in and achieve <1 mg/l nitrogen and phosphorus when facing sensitive environmental zones
This makes MATRIX a future-proof solution in areas facing strict planning or nutrient neutrality requirements.
Low Maintenance & Long-Term Value
Septic tanks often come with hidden costs: frequent desludging, soakaway failures, and even fines for pollution.
MATRIX systems are designed for low lifetime cost:
- No internal moving parts
- Annual emptying
- 25-year tank warranty
- 1-year blower warranty
That means fewer call-outs, less hassle, and more predictable long-term savings.
Built for Today and Tomorrow
MATRIX systems are designed to meet all current UK standards:
- BS EN 12566-3
- Building Regulations Part H
- British Water's Flows & Loads
- General Binding Rules
Compact, modular, and even available in containerised export units, MATRIX systems can scale from 6 to 5,000+ PE. Whether it's a single rural home, a holiday park, or a full development, MATRIX is ready.
Time to Upgrade
Septic tanks have served their purpose, but they no longer meet today's expectations, or tomorrow's standards.
MATRIX sewage treatment systems are:
- Compliant
- Efficient
- Environmentally responsible
- Cost-effective long-term
