Public Sewer Connections in Dorset
Complete sewer connection and highway works for developers, contractors and property owners
Dorset Drainage Services undertakes new connections to public sewer networks on private land and within the public highway.
As an approved contractor for Wessex Water and Southern Water, we can coordinate the connection process from applications and utility searches through excavation, traffic management, inspections and permanent highway reinstatement.

Sewer Connections for Developers & Contractors
One contractor from application to reinstatement
Public sewer connections can involve significantly more than laying a pipe. Work may require liaison with water companies, highways departments and utility providers as well as traffic management, deep excavation and final reinstatement.
Dorset Drainage Services can coordinate these stages directly as part of the sewer-connection service.
Connections for:
- Residential developments
- Commercial developments
- New-build sites
- Property conversions
- Industrial premises
- Individual new dwellings
- Existing properties moving from private drainage
- Contractor-led infrastructure projects

Public Highway Connections
Where the sewer connection is located within the highway, additional planning and coordination is required.
Our service can include:
- Underground utility mapping
- Highway applications
- Section 50 road-opening licensing where applicable
- Road-closure arrangements where required
- Traffic-management planning
- Water-authority applications
- Inspection coordination
- Permanent highway reinstatement
Deep Sewer Connections
Dorset Drainage Services is certified for deep excavation work to 10 metres. Where public sewers are deep, appropriate shoring or sheeting and safe working arrangements are required.
Public-sewer access can also involve confined-space procedures and breathing apparatus where necessary. This capability allows us to undertake more complex connection projects rather than limiting the service to shallow private drainage.

Our Sewer Connection Process
01
Review the proposed connection
Send us the drainage drawings, site details and proposed connection information.
02
Utility searches
Existing underground apparatus within the highway can be identified.
03
Applications
Relevant highway and water-company processes are coordinated.
04
Programme the work
Traffic management, access and site programme requirements are considered.
05
Excavate and connect
The connection and associated drainage are installed.
06
Inspections
Required inspections are coordinated with the relevant authority.
07
Reinstate
Highway or site surfaces are permanently reinstated.
Keeping Your Development Moving
Poorly coordinated sewer works can interfere with deliveries, site access and programme dates. Advance communication allows connection works to be planned around site operations and project timescales.
For developers and principal contractors, this should be treated as part of the programme rather than as a last-minute utility activity.

Private-Land Sewer Connections
Not every connection requires highway works. We also undertake associated sewer and drainage installation across private land, allowing the full route between the property or development and connection point to be considered as one project.
Complete Drainage Infrastructure
A development requiring a sewer connection may also need:
- Site drainage installation
- Manholes
- Pump stations
- Surface-water drainage
- Treatment systems
- CCTV inspection
- Testing
- Reinstatement
Our wider drainage and water capability means related works can be coordinated through the same contractor where appropriate.
For Individual Property Owners
Homeowners may also require a connection to the public sewer. We can discuss what information is available, review the proposed connection and explain what work is likely to be involved.

Coverage
