Septic Tank and Cesspit Conversions in Dunsfold
Convert a suitable existing septic tank or cesspit into a domestic sewage treatment plant with the Airseptor system, with minimal excavation and dependable aftercare.
C Humphrey Services provides septic tank conversions for homeowners throughout the Surrey Hills and surrounding rural areas. Where an existing septic tank or cesspit is suitable, the Airseptor system can convert it into a domestic sewage treatment plant without automatically replacing the complete tank.
This can be particularly useful for countryside properties where access, established gardens and avoiding unnecessary excavation are important considerations. We cover locations across the Surrey Hills including Shere, Albury, Gomshall, Peaslake, Abinger Hammer and surrounding Surrey villages.

Frequently Asked Questions
-
Often, yes. If the existing tank and drainage arrangements are suitable, Airseptor can convert it into a domestic sewage treatment plant without installing a completely new tank. We assess the existing system first, so Dunsfold homeowners can understand whether conversion is genuinely appropriate before committing to larger excavation work.
-
It can be significantly less disruptive because a suitable existing tank is retained rather than excavated and replaced. This can reduce digging around gardens, driveways and access areas. For rural properties around Dunsfold, we can assess what work would actually be required before providing a quotation.
-
A suitable cesspit may be capable of conversion using the Airseptor system. The existing structure and proposed discharge arrangements need to be assessed first, so conversion is not appropriate in every situation. Contact us with details of your Dunsfold property and we can advise on the practical options.
-
Yes. An Airseptor conversion still requires appropriate servicing and periodic tank emptying. C Humphrey Services states that converted systems typically require emptying around once every two years on average, although requirements vary depending on use and installation. We explain the ongoing maintenance requirements once the system has been installed.
-
C Humphrey Services provides ongoing support after installation. If one of our installations develops a problem, we aim to attend within 1-3 days and investigate the underlying cause rather than simply applying a temporary fix. Existing customers should contact us as soon as they notice something is not working correctly.
