WaterTrust Approved — every contractor is identity-checked with accreditation and insurance verified before they can quote.
What the work involves
- Excavation and laying of foul and surface water systems
- Manholes, inspection chambers, gullies and channel drains
- Grease management and petrol/oil interceptors where required
- Air/water testing and CCTV proof of the finished system
When you need it
- A new build, extension or change of use needing drainage
- Replacing an undersized or failed commercial system
- Separating combined foul and surface systems
- Connecting a site to the public sewer (Section 106)
How commercial installation is priced in Keswick
Commercial installation is priced against the design: flows, falls, separators, connection works and programme. Retrofitting an undersized system costs multiples of designing it right, so the design comes before any excavation — quotes should price against a design, and name the approvals.
Approvals to line up
- Building control sign-off on the drainage design
- A Section 106 sewer connection consent from the water company
- A Section 104 adoption agreement where the water company will take the new sewer over
- Oil separators to the environmental standard for forecourts and some yards
Programme milestones
The usual sequence for keeping an installation on programme: design signed off; building control and the sewer connection application lodged in parallel; excavation and pipe-laying with inspections before anything is covered; then the air test and CCTV survey that make up the sign-off pack. The approvals usually determine the timetable, so start them early.

Commercial drain installation in Keswick — common questions
Do we need a sewer connection application?
Any new connection to a public sewer needs the sewerage company's approval (a Section 106 application) — your contractor prepares the connection to pass inspection.
How long does connection consent take?
Commonly a few weeks — build it into the programme rather than the contingency.
Foul and surface water in one system?
No — new systems must keep them separate. Combining them is the classic costly mistake on older sites being extended.
Who grants the sewer connection here?
United Utilities — your contractor should raise the Section 106 application with them as part of the job, not leave it with you.
Who is responsible for this work in Keswick?
