Project Description

Project: Water Treatment Works Bickerstaffe.
Client: KMI and United Utilities.
Contract Responsibilities: Construction, Project Management.

The Overview

The existing service reservoir located at the Bickerstaffe wtw site is the hub which provides water to Southport DMZ as well as the local areas. The demand on this service reservoir varies from 32 to 59 million litres per day (ml/d) depending on the seasonal impact of tourists visiting Southport and the irrigation requirements of the local market gardening industry.

The Challenge

The amp 5 project consisted of the construction of a new water treatment works at Royal Oak, which is located adjacent to the existing Bickerstaffe site with a treated water output of 13 million litres per day. Simultaneously, four existing boreholes at Melling, which had been out of service for a number of years have been refurbished to be brought back into supply. An existing raw water main which was previously used to convey Melling water to an industrial user in Skelmersdale has been intercepted and extended to supply the new Royal Oak water treatment works.

The Solution

Gallaway’s involvement in the scheme was for the construction of the superstructure and internal fit out of both the treatment and the administration buildings. In addition to this, we constructed the top cladding façade and new roof structure inclusive of all structural steelwork and cladding to the rapid gravity feed building.
