Hemel East Primary substation had flooded numerous times, costing in excess of £1 million to rectify on each occasion. MLM were appointed to look at resolving the issue. We identified the source of the flooding (the site was not within a floodplain) and advised the Client on steps to mitigate flooding occurring in the future.

The Client however also wanted to elevate the substation such that if the source of the flooding was to reoccur the reliability of supply and his infrastructure would not be affected.

We looked at alternative sites and following discussions with all interested parties including the local planning Authority agreed on a location. This was an expansion, redevelopment and elevation of the existing site.

We prepared the design of the substation including all geotechnical, civil and structural engineering, and liaison with the Planning Authority. The Planning Authority also wanted the structures to be designed to be harmonious with the prestigious office development located nearby and as such MLM added architectural refinement to UK Power Network’s standard design.

We also prepared designs associated with temporary fault throwers and RMUs. The design included various value engineering features including the use of permeable surfacing where risk of contamination was low.
