South West Water Interworks Tankering


Gregory Distribution and South West Water have been in partnership since 2005, following a contract award to transport Interworks Sludges from over 600 collection sites to 24 treatment centres throughout Devon and Cornwall.

This area of our operations is one which we particularly pride ourselves on and we have introduced service-based policies, methods, new technology and innovations such as on-board measuring devices, LEV hose reels and tank monitoring systems which have transformed the way in which sludge transport and contract management is viewed by South West Water.

The introduction of these practices has allowed both parties to have unprecedented opportunities to manage and plan sludge treatment in conjunction with transport. The net result is that we have worked together in true partnership to identify and implement efficiency gains.

Our ability and willingness to address areas of improvement and work with South West Water in reducing costs is an asset which has benefited both companies – South West Water have reduced costs and closer control over its operations whilst Gregory Distribution has benefited through the award of new contracts and contract extensions.
