Can you work alongside my builder or architect?

Yes — we regularly coordinate directly with the main contractor or architect on extension and new-build projects.

How do you size a new drainage system?

Based on the property's expected water use, the number of fixtures being served, and existing ground conditions — particularly important on soakaway-dependent rural sites where a generic size can lead to recurring problems.

Drainage Installation across Dorset, Hampshire, Devon & the South.

New drainage systems designed and installed for extensions, developments and site improvements. A specialist team of drainage engineers based in Bournemouth, covering Dorset, Hampshire, Wiltshire, Somerset, Surrey and Devon — from first callout to written sign-off.

What's included

What's included.

New drainage installation starts with a design sized to the specific property and its expected water use, rather than a generic default. We install foul and surface water drainage, connecting either to existing mains drainage or to a newly designed soakaway depending on the site. All work is carried out to Building Control-compliant standards with full documentation provided, and every installation is confirmed with a post-installation CCTV pass before we consider the job complete.

Signs you need this

When you need a new drainage installation.

New drainage installation is most commonly needed for a house extension, a new-build or self-build project starting from scratch, or where existing drainage is undersized for a planned change of use. Converting outbuildings, or adding a new bathroom or kitchen that requires an additional connection, also typically calls for new drainage work designed around the specific fixtures being added, rather than simply extending an existing run that may not have the capacity.

How it works

Everything you need to know about drainage installation.

1. Design

A site assessment and drainage design sized correctly for the property, connecting appropriately to mains drainage or a new soakaway.

2. Installation

Work carried out to Building Control standards, with documentation provided for sign-off as part of the process.

3. Confirmation

A post-installation CCTV pass confirms the system is correctly laid and draining exactly as designed.
