When planning new developments, extensions, or even large-scale commercial works, one of the most overlooked but essential steps is understanding the condition and location of the existing drainage system. Without accurate information, projects risk costly delays, redesigns, and even structural failures down the line.
At Premier Drainage Solutions, we specialise in CCTV drain surveys, mapping, and re-lining, providing the technical insight developers, architects, and contractors need to keep projects moving smoothly. Whether you’re connecting to a public sewer, building near existing assets, or assessing ageing pipework, these tools are invaluable for both risk management and cost control.
Why CCTV Drain Surveys Matter
1. Mapping the Unknown
On many sites, especially older properties, drainage records are missing or inaccurate. A CCTV drain survey uses high-definition cameras to capture a live, internal view of the system, giving precise details on:
- Pipe diameter, material, and depth
- Alignment, junctions, and flow direction
- Condition, including cracks, defects, or obstructions
This information is vital for architects and engineers, enabling designs that avoid conflict with existing drains or allow for diversions if required.
2. Pre-Construction Compliance
If your works are near a public sewer, the water authorities often require CCTV survey evidence before granting approvals. It demonstrates that you understand the existing infrastructure and aren’t compromising the network.
3. Identifying Problems Early
From root ingress to fractured joints, issues picked up by CCTV surveys can be addressed before excavation begins. By planning remedial work in advance, you avoid emergency repairs that derail programmes and inflate costs.
The Role of Drain Mapping
CCTV is only the first step. Drain mapping takes the survey data and translates it into usable technical drawings, showing precise locations, depths, and connections across the site. This provides:
- A clear plan for diversions or new connections
- Accurate records for planning submissions
- Essential documentation for future facilities management
Drain mapping is particularly valuable when working on extensions, where new foundations may run close to existing drains. By having a detailed map, you can design with confidence.
When Re-Lining is the Right Choice
Not every defective pipe needs to be dug up and replaced. Re-lining offers a cost-effective and non-invasive solution that restores the integrity of drains without major excavation.
Our lining methods create a strong, jointless new pipe inside the old one, resolving issues such as cracks, root ingress, or water infiltration. Benefits include:
- Minimal disruption compared to excavation
- Faster installation, reducing programme delays
- Long-term durability, extending the service life of existing pipes
Re-lining is also an environmentally sustainable option, reducing waste and carbon impact compared to full replacement.
