# A Quick Guide to Underground Ducting
Underground cables and pipes play a critical role in modern infrastructure, ensuring essential utilities like electricity, gas, and water reach homes and businesses efficiently. These systems also support critical services such as CCTV, street lighting, and speed cameras. To safeguard these crucial services, it's vital to encase them within robust underground ducting. Made from high-density polyethylene (HDPE), this twin-walled pipe offers long-term durability and protection against environmental factors and potential damage.
## Key Benefits of Using Underground Ducting
1. **Protection**: HDPE ducting provides a durable shield against external impacts, root intrusion, and weathering, ensuring your services remain intact.
2. **Space for Insulation**: The ducting allows room for additional insulation, enhancing performance and longevity.
3. **Safety**: Properly color-coded ducting warns workers of the presence of vital utilities, reducing risks of accidental damage or tampering.
4. **Efficiency**: Installing ducting ahead of time minimizes delays in construction projects, allowing for smooth continuation of work without waiting for individual service installations.
## Installation Tips
Before installing underground ducting, it's crucial to select the appropriate type and color-coded ducting based on the service it will house. Here's a general guide:
- **Red or Black**: Used for electricity cables and power supplies.
- **Orange**: Reserved for street lighting and traffic signals.
- **Purple**: For motorway communication systems and Scottish street lighting.
- **Yellow**: For gas pipes.
- **Blue**: For water pipes.
- **Green**: For CCTV and fiber optics.
- **Grey**: General-purpose ducting, often used for telephone cables.
Always ensure that the installation area is free from existing utilities by using a locating device and consulting accurate land plans. Additionally, adhere to minimum burial depth regulations, which vary depending on the type of utility. For example, gas ducting typically requires a depth of 750mm, while water ducting should be buried between 250mm and 350mm.
## Inspecting Ducting
If you suspect damage to your underground ducting, proceed with caution. Begin with a risk assessment to determine if the surrounding soil contains corrosive substances or if recent events might have caused damage. Before excavation, ensure all utilities are turned off to avoid any potential hazards.
Inspect visually for signs of wear, such as cracks, thinning, or broken connections. If damage is confirmed, refer to the NJUG Guidelines for safe repair procedures.
