Project Brief

The modernisation programme of the multimillion pound project involves significant remediation of previously abandoned land, followed by construction of six circular primary settlement tanks (PST) and a large activated sludge plant (ASP) with 10 circular final settlement tanks (FST). This work will lead to significant environmental benefits for the site, improving the outflow, and subsequently the quality, of water entering the Manchester Ship Canal.

 

Marshalls Civils and Drainage Solution

Following the appointment of Laing O’Rourke to undertake the modernisation of the Davyhulme Waste Water Treatment Works in Manchester by United Utilities, the Marshalls Civils and Drainage was employed to supply bespoke precast box culverts to the largest treatment plant in the Northwest, which serves over a million people.

The Davyhulme wastewater treatment works expansion is due to be completed in 2018.

Paul Whyte, Marshalls Civils and Drainage Sales Manager commented: “Marshalls Civils and Drainage's precast concrete box culverts are designed and manufactured in both standard sizes available from stock as well as a bespoke range that is manufactured to customer specification, so are an ideal fit for a project such as this, as we are able to ensure the customer choice as well as durability, proven strength and the services of our civil engineers. Marshalls Civils and Drainage is also able to offer BIM (Building Information Modelling) which was of great interest to this project”.
