The gasworks site at Gloucester operated from the early 1860’s until it was decommissioned in the early 1970’s. The remediation which begun in 2011 represented the largest site remediated by National Grid that year.
During its history, the gasworks was redeveloped several times in line with emerging technologies. From the 1950’s until closure it was used as an experimental site to test several different methods of gas production; meaning the site itself had more underground structures than an ordinary gasworks site. The site was located in a predominantly industrial area, close to the Sharpness Canal within the Southwest region of England. This coupled with its close proximity to residential housing and local businesses meant sensitive handling of the remediation and a comprehensive programme of community relations was essential.
Erith were employed to carry out the land remediation works at Gloucester Gasworks in February 2011. This was based on an environmental improvement strategy, targeting key source areas of the site including the following:
- Below Ground Gas Holder
- Tar Tank
- Storage Areas
The above areas encompassed the requirement of substantial excavation with approximately 85,000m3 of material excavated, stockpiled, screened and tested for contamination.
The site, which spanned approximately 12 hectares, also saw the testing of soils for reuse, demolition of concrete ancillary buildings, workshops and garages and infilling of site won crushed material.
To ensure Erith created positive working relationships with stakeholders, clients and neighbours, we operated a stakeholder engagement programme. This took into account consideration during planning/design of potential impacts on surrounding neighbours/local stakeholder groups including: Gloucester City Council, EA, local businesses and local residents groups
