Septic tank conversion, compliance checks and upgrade enquiries
Real feedback from homeowners and businesses across Hampshire, Surrey & West Sussex.
Many rural and off-mains properties still rely on older septic tanks that may no longer be suitable, compliant or reliable. Septic tank conversion is often required where an existing system discharges incorrectly, causes pollution risk, fails a property sale inspection or no longer meets current wastewater requirements.
Alton Facility Services can assess your existing septic tank, advise on compliance, decommission unsuitable systems and install a modern sewage treatment plant where this is the most appropriate solution. We also provide ongoing sewage treatment plant maintenance to help keep the system working correctly after installation.
You may need septic tank conversion if your existing system is outdated, failing, non-compliant or unsuitable for the property. Common reasons include:
A septic tank conversion should always be planned around the property, discharge route, ground conditions, occupancy levels and current compliance requirements. We do not recommend replacing equipment blindly without first understanding the existing system and the reason for upgrade.
Our septic tank conversion process is designed to identify the correct solution before installation work begins:
The aim is to provide a compliant, reliable wastewater system that suits the property and can be maintained properly over the long term.
If your septic tank has failed, is backing up, producing odours, causing pollution concerns or has been flagged during a property sale, we can provide urgent assessment and practical advice.
Where a full conversion is required, we can help plan the next steps, including system selection, installation requirements, commissioning and future maintenance.
Our septic tank conversion service can include site assessment, compliance review, treatment plant selection, excavation, old system decommissioning, sewage treatment plant installation, commissioning and maintenance planning.

Common questions about septic tank conversion, compliance checks and sewage treatment plant upgrades.
The general binding rules set out how septic tanks and small sewage discharges must operate to reduce the risk of pollution.
