Drainage & SuDS Solutions
Smarter Water Management for Safer, Sustainable Sites
At Killingley, we design and deliver drainage systems and Sustainable Drainage Solutions (SuDS) that protect sites from flooding, manage surface water responsibly, and create long-term resilience. Our engineered systems balance practical performance with sustainability, ensuring compliance with modern planning requirements while enhancing the wider landscape.
From car parks and industrial estates to housing developments and public spaces, our drainage and SuDS solutions integrate seamlessly into hard landscaping works, reducing risk while supporting environmental objectives.
With decades of experience in civil engineering and landscape construction, we provide end-to-end delivery — from design through to installation and aftercare. For a wider view of our construction expertise, see our Hard Landscaping services.
Building Resilient Infrastructure
Effective water management is a cornerstone of every successful project. Without proper drainage, sites are exposed to flooding, erosion, and long-term maintenance costs. By combining traditional engineering with innovative SuDS design, we create solutions that are durable, adaptable and sustainable.
Our Drainage & SuDS Expertise
Surface Water Drainage

Where Our Systems Are Applied
Our drainage and SuDS services are trusted across a wide range of projects:
- Car Parks & Pathways – permeable surfacing and engineered drainage solutions
- Commercial & Industrial Sites – large-scale water management infrastructure
- Housing Developments – SuDS features designed for long-term resilience
- Educational & Public Spaces – safe, sustainable drainage for communities
- Highways & Infrastructure – flood-prevention measures for busy transport networks
Delivering Long-Term Security
We believe drainage and SuDS are more than just compliance requirements — they are critical to building safe, climate-ready landscapes. Our blend of engineering expertise and sustainable design ensures every project delivers long-term value for clients, communities and the environment.
Our systems are designed for whole‑life performance. We specify durable materials, accessible inspection points and clear maintenance regimes for permeable paving, swales, basins and ponds. Every project is handed over with O&M manuals, as‑built drawings and an asset register, with training for site teams or FM providers to ensure smooth adoption by local authorities and water companies where required.
We act as a long‑term partner to keep assets performing. Seasonal inspections, desilting schedules and vegetation management maintain flow, infiltration and water quality; where site use changes, we provide proactive upgrades to protect capacity. The result is reduced risk and lifecycle cost, with SuDS that continue to enhance amenity and biodiversity year after year.
