Work starting in the 21 day tank area

Last week excavations started in the area for the 21 day tanks - which will hold thickened sludge during the annual incinerator shutdown. We are excavating out everything inside some old storm tanks which will then be backfilled to provide a good foundation for the new tanks.

Introduction to the scheme

This scheme is one that will really impact the work of the operators of the largest sewage treatment works operated by Yorkshire Water.

This project will provide odour control facilities to new and existing plant and new sludge treatment facilities and also involves modifications to existing facilities which will improve sludge management at the site.

Today Excavation is continuing for the 2 sludge tanks that will store sludge in covered tanks prior to incineration.

We are digging down within old storm tanks that have been used as a landfill and have found newspapers from 1956 - with the top 10 on!

Currently B&V are addressing the challenge of an unchartered pipe discharging into a culvert through the excavation.

Material from the excavation will be crushed and reused where possible as backfill to reduce the amount of material going to landfill.

Project Particulars

Brief Description of 'The Works'

Design and build a new odour control scheme at High and low level works including associated new structures to provide sludge storage, sludge thickening facilities and all the necessary activities to fully integrate the new process into the existing operations on site, comprising of:

• Additional sludge storage and transfer at high level works
• Odour control of new sludge storage facility at high level works
• Storm tank cleaning system at high level works
• Additional new storage at low level worksand conversion of existing storage
• Sludge thickening facilities at low level works
• Storm tank cleaning system at low level works
• Sludge mixing to new and converted sludge storage facilities
• Odour control of new sludge storage facility at low level works
• Interconnecting process pipe work
• Control building and power supply infrastructure
• Commissioning and testing of installation
