Project Overview:

The proposed works involved excavating for and constructing 75 meters of an offline DN900 PCC FWS to increase capacity by 11m3 and divert the existing DN750 FWS. The site identified for the proposed diversion was owned by National Grid, and access was identified as being via Bushey Cricket Club. The River Colne runs adjacent to the site, which increased the risk of flooding. To achieve the desired outfall level relevant to the existing public sewer, the depth of excavation would be nominally 3 meters below ground level.

Glenea contract's Services and Expertise:

Glenea Contracts’ specialised services relating to civil engineering and wastewater network reinforcement were crucial to the successful completion of this project. Our expertise in traditional open cut trench excavation and construction works was essential in executing the proposed works. Glenea Contracts’ commitment to quality workmanship, safety, and teamwork were also vital to the project's success.

Project Specific Complexities:

The project was not without its complexities. The ownership of the site by National Grid made access challenging, and access was identified as being via Bushey Cricket Club. The River Colne running adjacent to the site increased the risk of flooding, and the excavation depth required to meet the existing public sewer was nominally 3 meters below ground level.

Proposed Works:

To meet the increased demand for the existing wastewater asset identified by Thames Water in advance of the proposed Watford Riverwell Redevelopment at Watford General Hospital, we executed the traditional open cut trench excavation before laying the proposed DN900 PCC FWS. Despite the less than favourable ground conditions, we were able to complete the project within budget and prior to the planned completion date.

Project Outcome:

The project was successfully completed much to the satisfaction of Thames Water and other stakeholders. Glenea reinstated the site and access road through Bushey Cricket Club to the stakeholder's satisfaction. Working closely with the Agility Alliance and the respective stakeholders, Glenea procured and installed a temporary 45-tonne capacity bridge and ground bearing mats, thus establishing a serviceable access route and working platform.

Glenea's Values and Mission:

Glenea's mission is to provide high-quality civil engineering solutions that meet the needs of our clients and stakeholders. Our commitment to quality workmanship, safety, and teamwork was evident throughout the project. Glenea is a reliable and competent civil engineering company that specialises in excavation and construction works relating to wastewater assets and network reinforcement.

Conclusion:

The Glenea project completed for the Agility Alliance JV as part of the Thames Water London Infrastructure Programme is an excellent example of Glenea's specialised services, expertise, and commitment to quality workmanship, safety, and teamwork. Glenea successfully completed the project within budget and prior to the planned completion date, much to the satisfaction of Thames Water and other stakeholders.
