Project Overview:

The project was executed in November 2020 and had an approximate value of £60,000. Glenea's role was to excavate and construct a DN300 combined sewer connection to the public wastewater network.

Proposed Works:

The proposed works comprised the excavation for and construction of a DN300 combined sewer connection for 29 proposed residential units in the Peckham urban area.

Project Specific Complexities:

Meeting House Lane, where the project was located, is a busy urban thoroughfare, which is strategic to residents and local businesses. Southwark Council stipulated that traffic must not be inconvenienced during the proposed works. Additionally, the depth of excavation required to achieve the desired outfall level relevant to the existing Victorian era public sewer exceeded 4 meters below ground level.

Innovations & Solutions:

To overcome the project complexities, Glenea worked closely with the developer and Agility Alliance to devise a solution comprising excavation of a traditional timber heading. This approach ensured the desired excavation depths were achieved while eliminating any disruption to road users. The DN300 combined sewer connection was terminated with a PCC manhole within the developers' site, allowing for future connection by others.

Project Outcome:

The project was successfully completed within budget and prior to the planned completion date, much to the satisfaction of Southwark Council. Glenea's innovative approach to the excavation of the sewer connection ensured that traffic was not inconvenienced, and the desired outfall level was achieved, thereby meeting the project's objectives.
