Technical review of Non-Hazardous Leachate storage tank containment and associated risks.

Project Background
Smallbrook Environmental was asked by a waste management operator to conduct a CIRIA  736 secondary containment assessment of its 2 leachate storage tanks and 1 treatment tank on its site in the South of England.

Project Objectives
The key objective of the project work was to provide the operator with a CIRIA 736 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

- 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.

Our Role
- Visual inspection of the 3 tanks in association with the quantitive measurement of the thickness of the tanks.
- Provision of a report consolidating all of the information and data collated during the site visit and summarising and evaluating the readings from the ultrasonic thickness testing.

Outcomes
Production of review findings for each tank reported in  coloured diagrammatic representations.
Recommendations on tank remedial works if any.

Benefits
Provide the waste management operator with an assessment of the level of thickness degradation of their tanks against any design specification.
Alert the company to any issues with the tanks which could compromise the integrity of their containment systems.
