HDD Pumping Main Installation for Housing Estate Sewer

Brennan Building and Civil Engineering

Directional Drilling Rising Mains Pipe Installation, Leicestershire

Installation of 145 linear metres of 125mm SDR11 HDPE rising mains pipe using Horizontal Directional Drilling to connect a construction site to the main sewer line via a break chamber. Installation was carried out through a busy urban area and across a main road and therefore presented significant challenges to minimise disruption and ensure safety. The project took place over the course of 3 days in the village of Quorn in Leicestershire.

Technical Execution and Achievements

Drilling Specifications

Selecting 125mm OD SDR11 HDPE black pipe was crucial for ensuring the mains' durability under the project's specific ground conditions.

Innovative Solutions and Challenges Overcome

The project presented unique challenges, including congested urban spaces and dense underground utilities. To address these, EPS Trenchless Installations conducted some of the drilling operations out of hours during the night. This approach significantly reduced the impact on the public and ensured the safety and efficiency of the operation, especially when navigating through busy junctions and roads..

Expertise in HDD and GPRS

Integrating HDD skills with GPRS for precise utility mapping exemplifies our innovative approach to infrastructure projects. Our capacity to execute complex drilling routes efficiently demonstrates our leadership in the industry.

Project Highlights

Scope of work

The project involved the installation of 145 linear meters of 125mm SDR11 HDPE rising mains using state-of-the-art HDD techniques. This effort connected the construction site to the main sewer line via a break chamber, overcoming urban drilling challenges.

Advanced GPRS Utilization

The deployment of Ground Penetrating Radar Systems (GPRS) was critical for accurately mapping underground utilities. This technology underpinned our bore path planning, ensuring avoidance of existing utilities and minimizing disruption.

Bore Path Design and Planning

Detailed planning, informed by GPRS data, was instrumental in designing an optimal drilling route. This approach mitigated obstacles and reduced environmental impact, showcasing our thorough preparation and execution strategy.
