Understanding Drain Responsibility

This diagram shows which drainage pipes are your responsibility and which are maintained by the water authority.

Private drains run from your property to the point where they connect with neighbouring drains. These are usually the homeowner’s responsibility to maintain and repair.

Lateral drains carry wastewater from your property to the public sewer, even if they run outside your boundary. These are typically the responsibility of the local water company.

Public sewers serve multiple properties and are maintained by the water authority.

Knowing who is responsible can help you act quickly if you experience a blockage or drainage issue and avoid unnecessary costs.

No dig technology - Patching & Lining

No-dig drain pipe replacement is an efficient, non-invasive solution for repairing damaged drainage systems without disrupting business operations.

Using cured-in-place pipe (CIPP) lining, a resin-impregnated liner is installed within the existing pipe and cured to create a structurally sound, seamless internal pipe. This method restores full pipe integrity while minimising downtime.

Key benefits for commercial properties:

✔️ Minimal disruption to Home owners, staff, customers, and operations
✔️ Reduced downtime compared to excavation works
✔️ Cost-effective alternative to full pipe replacement
✔️ Suitable for retail, industrial, and commercial sites

No-dig drain lining is ideal for businesses, property managers, and facilities teams seeking a reliable, long-term drainage repair solution.

High Pressure Water Jetting (HPWJ)

High Pressure Water Jetting (HPWJ) is a powerful and efficient method for clearing and maintaining commercial & domestic drainage systems.

By delivering water at high pressure, HPWJ removes grease, scale, silt, debris, and root ingress from pipework, restoring full flow and reducing the risk of repeat blockages. It is commonly used in planned maintenance programmes and before CCTV drain surveys.

Key benefits for commercial properties:

✔️ Effective for high-usage drainage systems
✔️ Minimises disruption to operations
✔️ Reduces the risk of costly drainage failures
✔️ Suitable for retail, hospitality, industrial, and commercial sites

HPWJ is an essential service for facilities managers and property owners looking to maintain safe, compliant, and efficient drainage systems.

CCTV drain surveys

CCTV drain surveys offer a professional and efficient way to assess the condition of commercial, public and private drainage systems with minimal disruption.

Our advanced camera systems allow us to inspect pipework in real time, identifying structural defects, blockages, root ingress, and compliance issues. Detailed reports and footage support informed decision-making, planned maintenance, and repair planning.

Key benefits for commercial properties:

✔️ Minimises downtime and disruption
✔️ Supports planned maintenance programmes
✔️ Assists with compliance and asset management
✔️ Suitable for industrial, retail, and multi-occupancy sites

CCTV drain surveys are an essential tool for facilities managers and property owners looking to maintain efficient, compliant drainage infrastructure.

Interceptor Removal & Non-Return Valve Installation

Many older drainage systems include interceptors that are no longer required and often cause restricted flow, recurring blockages, and maintenance issues. Modern drainage design means these interceptors can often be safely removed to improve overall system performance.

When an interceptor is removed, there is also the option to install a non-return valve. This allows wastewater to flow out normally while automatically preventing reverse flow, helping to protect properties from sewage backflow during heavy rainfall or sewer surcharging.

Benefits of interceptor removal and non-return valve installation:

✔️ Improved drainage flow and performance
✔️ Reduced risk of recurring blockages
✔️ Optional protection against backflow and flooding
✔️ Modern, low-maintenance drainage solution
✔️ Suitable for both residential and commercial properties
