Drainage Company in Kent
Drainage Installation for New Build and Development Projects
Getting drainage right from the outset is one of the most important things you can do on any new development. Poor water management leads to waterlogging, soil erosion, and in serious cases, structural damage to foundations and hardstanding. As a drainage company in Kent working across new build and development projects, Fry Site Services carries out full drainage installation from ground level up.
Our drainage work on new projects includes:
- Surface water drainage systems including channel drains, gullies, and pipework
- Foul water drainage installation and connection to mains sewer where applicable
- Soakaway design and installation, including crate soakaways and rubble-filled systems
- Attenuation tanks for sites where water storage and controlled discharge is required
- Culverts and watercourse management
- Land drains for sites with high water table or poor natural drainage
We carry out site assessments, including soil permeability testing where required, to make sure the system we design and install will actually do the job. Every installation is carried out in line with UK building regulations, local authority requirements, and any planning conditions attached to your development.
Land Drainage Across Kent
Kent’s landscape varies considerably. Parts of the county sit on heavy clay soils with naturally slow drainage, while other areas are prone to surface water run-off from sloping ground or impermeable surfaces. Agricultural land, sports pitches, school grounds, and private estates all face drainage challenges that, left unaddressed, reduce the usability and value of the land.
We install land drainage systems that channel water away from areas where it causes problems. This typically involves a network of perforated pipes laid in trenches, connected to an outfall point that may be a soakaway, a watercourse, or an attenuation system. The right approach depends on ground conditions, the volume of water to be managed, and any constraints on where water can be discharged.
Land drainage work is often carried out alongside other groundworks. Where excavation is already taking place as part of a wider development, drainage installation can be incorporated without the cost of a separate mobilisation.
Commercial Drainage Projects
Commercial sites have particular drainage demands. Car parks, logistics yards, industrial estates, and commercial developments all generate significant volumes of surface water run-off that needs to be managed correctly. This includes compliance with regulations around pollutant management for sites where vehicles, fuel, and chemicals are present.
We design and install drainage systems for commercial clients across Kent, and our work also extends into South London and parts of East Sussex where projects require it. This includes interceptors and petrol separators for areas with vehicle movements, channel drain systems capable of handling high flow rates, and connections to adopted highway drainage where applicable.
We work directly with developers, principal contractors, and commercial property owners. Details of our commercial drainage work can be found on our dedicated commercial drainage page. We hold Constructionline Gold accreditation, which gives supply chain confidence for managed commercial projects.
Residential Drainage in Kent
Residential drainage projects require a different approach. Many homeowners and self-builders across Kent encounter drainage problems during planning or construction, whether it is a soakaway that is failing, a site where existing drainage is inadequate for an extension or new build, or land that needs draining before it can be developed or used properly.
We work on residential drainage projects of varying scale. This includes soakaway replacement and installation, drainage for new driveways and hardstanding, and connection of surface water systems to existing infrastructure. All residential drainage work we carry out complies with Part H of the Building Regulations and any relevant planning conditions. More information on our residential drainage services is on our dedicated residential page.
Sustainable Drainage Systems (SuDS)
Sustainable drainage is now a planning requirement for many new developments in England. Fry Site Services has experience installing SuDS-compliant systems that manage surface water run-off at or close to source, reducing the volume and speed of water entering drainage networks.
SuDS solutions we install include permeable surfacing, swales, detention basins, and infiltration systems, depending on the site conditions and the SuDS hierarchy requirements set out in planning guidance. Where a SuDS strategy has been designed by a drainage engineer or planning consultant, we carry out the physical installation to specification. For smaller projects where a formal strategy is not required, we advise on the most practical and compliant approach.
Drainage Upgrades and Infrastructure Improvement
Not all drainage work starts from scratch. Many sites across Kent have drainage infrastructure that is ageing, undersized, or simply no longer fit for purpose following a change of use or increase in development density. Poor drainage causes real problems: waterlogging, subsidence, surface flooding, and damage to surrounding structures.
We survey existing drainage, identify the source of problems, and install improvements that address the root cause rather than masking it. This might mean increasing pipe capacity, installing additional soakaways or attenuation, redirecting flow, or replacing failed sections of pipework. All upgrade work is documented and signed off in line with current regulations.
Why Use Fry Site Services
Fry Site Services holds Constructionline Gold accreditation, covering health and safety, environmental management, and financial standing, which gives clients confidence when appointing us on managed projects. As a drainage company in Kent, we work across residential, commercial, agricultural, industrial, and public sector sites throughout the county and into South London, East Sussex, and Essex. Every project starts with a proper site assessment and drainage design, not just an installation. Where planning requires it, we install SuDS-compliant systems, and because drainage sits within our wider groundworks offer, it can be delivered alongside excavation, foundations, and surfacing as part of a single coordinated programme. Clear project management and full compliance documentation come as standard throughout.
Other Services We Offer
As well as offering drainage services, Fry Site Services offer construction site clearances, drilling, excavation and groundworks, foundations and underpinning, land preparation, landscaping, roadways and footpaths, and surfacing.

Frequently Asked Questions
What types of drainage do you install?
We install surface water drainage, foul water drainage, land drainage, soakaways, attenuation tanks, culverts, channel drains, and SuDS systems. The right solution depends on the site, the volume of water to be managed, ground conditions, and the relevant planning or building regulations requirements.
Do you work on both commercial and residential sites?
Yes. We carry out drainage installation and upgrades for commercial developers, businesses, homeowners, self-builders, agricultural landowners, and public sector clients throughout Kent and into the surrounding areas.
Do you design drainage systems or only install them?
We carry out site assessments, including permeability testing, and design drainage solutions appropriate to the site. For larger commercial projects where a structural or drainage engineer has produced a formal drainage strategy, we install to that specification.
Do you comply with building regulations?
Yes. All drainage work carried out by Fry Site Services meets the requirements of Part H of the Building Regulations, Environment Agency guidance, and any specific planning conditions attached to the site. We provide documentation throughout the process.
Can you carry out drainage work as part of a wider groundworks project?
Yes, and this is often the most efficient way to approach it. If excavation or site preparation work is already planned, drainage installation can frequently be incorporated within the same programme, reducing cost and disruption.
