The Problems of Open-Cut Trenching

What is Open-Cut Trenching?

Trenching is an original method for laying, replacing, or repairing utilities. This requires large amounts of earth to be removed and excavated, leaving a trench and the existing utilities exposed.

What are the main problems with Open-Cut Trenching?

Disruption and Delays

Trenching requires digging up sizable areas, disrupting traffic flow, pedestrian access, and business operations. This can lead to project delays and lost revenue.

Safety Hazards

Open trenches pose safety risks to workers, pedestrians, and animals who might fall in. Additionally, exposing underground utilities can lead to accidental damage.

Cost

The cost of labour, equipment, and restoration after trenching can be quite high. There can also be additional costs associated with acquiring correct permits, traffic control, and unforeseen issues such as unexpected utilities or unsuitable ground conditions.

Environmental Impact

Protected areas such as Root Protection Zones (RPZ), Ancient Woodlands, Tree Preservation Orders (TPO), and Sites of Special Scientific Interest (SSSIs) can be substantially disturbed and affected by open-cut excavations. These areas are critical for biodiversity and ecosystem stability, and disturbance can lead to irreversible damage to habitats and species. Trenchless technologies like horizontal directional drilling (HDD) offer a vital alternative, minimising disturbance to these sensitive environments while allowing for the installation of necessary utilities and infrastructure.

Carbon Footprint

By using large machines that are designed to remove large amounts of earth for excavation, open-cut trenching methods contribute significantly to carbon emissions. These machines consume large amounts of fuel and require frequent transportation of excavated materials, leading to higher energy usage and emissions. HDD drilling minimises these impacts by reducing the need for extensive excavation and associated heavy machinery. This not only lowers carbon emissions but also promotes a more sustainable approach.

Trenchless technology - a modern alternative

Trenchless technologies are becoming increasingly popular due to their ability to minimise disruption and environmental impact, offering a modern and thorough alternative to traditional trenching methods.

EPS Trenchless Installations, specialise in applying trenchless technologies to eliminate the need for extensive excavation. This preserves landscapes and minimise disturbance to the environment, communities, and existing infrastructure.
