Drainage Services in Chew Magna

Chew Magna and the surrounding villages sit within the Chew Valley on predominantly clay soils, with the Chew Valley Lake nearby influencing the local water table. Many properties here are older stone cottages with drainage laid long before modern standards, often narrow-bore clay pipe running at shallow depth, and root ingress from established gardens and hedgerows is a frequent cause of slow drains and blockages.

Being outside Bristol and Bath's built-up areas, a significant number of homes in the Chew Valley rely on septic tanks or private treatment plants rather than mains sewerage. The clay-based soil drains slowly, which makes soakaway design and percolation testing particularly important when a system is replaced or upgraded, to avoid problems with effluent dispersal in wet ground.

We approach drainage work in Chew Magna with a CCTV survey to assess old clay pipework and pinpoint root damage before deciding on a repair. High-pressure jetting is used for routine blockages, while no-dig lining suits older cottage drainage where digging up cobbled yards or established gardens is best avoided. For septic tank properties we carry out percolation testing to guide any new soakaway design.
