Sewer Connections
Storm and foul water connections for both large commercial developers and small domestic clients. We liaise with the local water authority (such as Thames Water, Southern Water or Anglian Water’) on your behalf, from application stage to sign-off / approval, as well as dealing with the local council in relation to permits and any traffic management.

Sewer Diversions /
Build Over Agreements
Diversion of the existing sewer for both large commercial developers and domestic clients. If you are extending or making other alterations to your property, you may need to divert your sewerage line and a build over agreement is required by water companies for any construction work over or within 3m of a public sewer. We liaise with the local water board authority (such as Thames Water) to ensure works are completed to their standards, enabling your deposit to be reimbursed.

Removal of Drainage Interceptor Traps
A drainage interceptor trap is an outdated device located within a sewer pipe. Silt and debris can collect in these causing blockages in the drainage system. We can remove these to prevent any future blockages and can install a new pipe branch or demarcation chamber.

Excavation methods
we undertake:
Tunnelling
Tunnelling is one of the methods of reaching the existing sewer in order to install a new connection. It involves excavating under the road and/or footpath via timber headings. Tunnelling avoids the need to break/excavate the surface of the road, thus saving time and money in liaising with the local council regarding permits/licencing and any traffic management. Furthermore, the road and footpath can be maintained and operate as normal.
We provide a temporary works design to demonstrate that the structure has been installed safely and is guaranteed.
