The existing service reservoir located at the Bickerstaffe WTW site is the hub that provides water to Southport DMZ and the local areas. The demand for 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 amp 5 project consisted of constructing new water treatment works at Royal Oak, 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 several years, have been refurbished to be brought back into supply. In addition, an existing raw water main 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.

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