Drainage &
Sewers
Drainage contractors in Surrey for sewer connections, soakaways and site drainage.
Correct drainage protects programmes, structures, and finished surfaces. We deliver domestic and commercial drainage packages across Surrey, from shallow plot drainage to deep sewer connections in the highway.
LG Groundworks specializes in both Foul Water and Surface Water systems. We coordinate Section 50 and Section 106 connection work, inspection chambers, attenuation, and compliance requirements so drainage is not left as a weak point on the job.
Where drainage and sewer searches should funnel into LG Groundworks.
These links connect commercial drainage intent with the towns most likely to convert. They also give search engines clearer context for where your drainage and sewer expertise applies.
That separation is one of the core compliance questions clients ask, so it now sits higher in the page and links into the FAQ and related-service journey.
Section 50 and 106 references give the page stronger commercial intent than a generic “drainage” page and help qualify harder jobs.
Users can now move directly into site prep, foundations, and earthworks pages instead of hitting a dead end after the drainage content.
Drainage Systems
Foul Water Systems
Installation of pipework, inspection chambers, and connections to main sewers or treatment plants.
Surface Water
Managing rainfall via soakaways (BRE 365 compliant), attenuation tanks, and channel drainage.
Deep Sewer Connections
We execute high-risk deep drainage operations using drag boxes and trench sheeting. Our team handles the Section 50/106 applications and traffic management required for highway works.
Repairs & CCTV
Diagnosing blockages and collapsed pipes using CCTV technology, followed by repair or replacement.
01. Survey
We assess levels and ground conditions (percolation tests) to design an efficient system.
02. Excavate
Trenches dug with laser precision. Trench support systems installed for deep works.
03. Install
Pipework and inspection chambers installed on pea shingle beds to prevent movement.
04. Test
Air or water pressure testing ensures the system is watertight before backfilling.
Common Questions
Understanding the difference between systems is crucial for compliance.
Foul water comes from toilets, sinks, and appliances and must go to a treatment plant or sewer. Surface water is rain from roofs and driveways, which should go to a soakaway or storm drain. They must be kept separate.
Yes. Connecting to a public sewer requires approval from the water authority (Section 106). We are accredited to carry out these works in the highway safely and legally.
Yes, for rural properties without mains drainage, we supply and install septic tanks and modern sewage treatment plants that comply with current environmental regulations.

Searchers looking for drainage contractors often also need enabling works, excavation, foundations, or basement support on the same job.
