Services - Site investigation, environmental impact assessment, financial liability assessment, Ultrasonic tank testing inspection.
Technical review of Non-Hazardous Leachate storage tank containment and associated risks.

Project Objectives - To provide the operator with a CIRIA736 assessment of the level and likely effectiveness of secondary containment systems installed for the leachate storage and treatment tanks at the site. Assessing the primary, secondary and tertiary containment measures that were in place.

Our Role
- Visual inspection of the 3 tanks
- Production of a baseline condition report to outline the current level of containment, identifying existing and potential risks and setting out possible improvement actions necessary to ensure the secondary containment of the tanks
- Provision of a report consolidating all of the findings from the inspections and undertaking a related BAT assessment and contaminated risk assessment, summarising the possible options to ensure full secondary containment, following the CIRIA 736 guidance.

Outcomes Production of a report summarising and reviewing the findings for each site and identifying recommendations to help the operator mitigate any current and future risks from failures in primary containment systems.

Benefits
The work allowed the company to better understand the containment risks and possible failure scenarios for the storage vessels and thereby make informed judgements as part of their asset maintenance and management programme.
