How We Approach Drainage Installations
Our approach to drainage installations is grounded in technical precision and full compliance with Approved Document H – Drainage and Waste Disposal. For larger projects, our qualified drainage engineers will design and map the proposed drainage systems, ensuring every component meets the requirements for inspection, maintenance and long-term durability.
Trench Excavation: Trenches are dug to a correct and consistent "fall" (slope) to facilitate efficient water flow. Each trench is typically 300mm wider than the pipe it contains and must allow for 300mm of cover above the pipework.
Pipe Bedding: Trenches are lined with pea shingle, providing a stable and protective bed for the pipework. This bedding reduces pipe movement and risk of damage.
Pipe Laying: Pipes are joined using a push-fit system with rubber seals. Fittings feature either spigots or sockets to ensure secure and leak-free connections. Layouts are designed for optimal access, allowing for rodding, testing, cleaning, and inspection.
Backfilling: Once installed and checked, trenches are backfilled using suitable materials, reinstating ground stability and surface finish.
Our expertise covers all types of drainage systems, including:
- Surface Drainage: Effective removal of surface water using ditches, swales, and channels
- Subsurface Drainage: Installed beneath soil to manage groundwater and improve soil structure
- Slope Drainage: Redirects water efficiently on uneven or inclined terrains
- Downspouts & Gutter Systems: Collects and conveys roof water into the surface or subsurface network
Ensuring Compliant, Effective Systems
Smart Drainz ensures that all drainage installations comply with Building Regulations Part H and Water Industry specifications. Our drain technicians are trained to understand and implement best practices in design and installation.
We provide guidance and liaison with your local authority’s Planning & Building Control department, including submitting drainage plans or securing prior approval. Regardless of where you are in the South of England, we can help map existing drains or request official drainage plans on your behalf. We also conduct percolation tests for off-mains drainage and soakaway system designs.
Our team supports clients through each regulatory step, including:
- Ensuring access for maintenance and cleaning
- Managing pipe gradients and load-bearing protection
- Designing systems that account for future connections
- Meeting General Binding Rules where relevant
From new drains for a single property to large-scale housing developments, every installation is tailored for longevity, compliance, and resilience.
When to Consider a New Installation
New drainage installations may be required in several scenarios:
-
New Build Homes
Where a fresh drainage system is needed to serve new kitchens, bathrooms, and external connections.
-
Extensions & Renovations
Adding new facilities often requires additional or updated drainage infrastructure.
-
Replacement of Failing Systems
Collapsed, corroded, or incorrectly sloped drains should be replaced to prevent structural and environmental damage.
-
Development Projects
From housing estates to commercial premises, schools, farms and hospitals, Smart Drainz handles the drainage scope of major building works.
Our skilled drain technicians ensure installation is fast, efficient, and disturbance is kept to a minimum. If you’re working in any of the areas we cover across the South of England, our knowledge and regulatory expertise make us the ideal partner.
FAQs - Drainage Installations
If you're developing a new site, adding an extension, or have signs of system failure such as odours, leaks, or slow drainage, a new installation may be necessary.
In many cases, drainage works fall under Building Regulations rather than Planning Permission. We can help you liaise with Building Control and secure the necessary sign-off.
For a 110mm pipe, the typical minimum gradient is 1:40. Our engineers will design the trench fall to meet regulatory flow requirements.
Yes. We undertake drainage work for farms, factories, schools, hospitals, and office developments, providing end-to-end project management.
Yes. We provide percolation testing, General Binding Rules guidance, and can obtain or create drainage plans where required.
