Plastic single skinned tanks are used less and less and there are various rules and regulations to be aware of when installing a plastic tank, these include;
- The capacity of the oil tank must be less than 2500 litres
- The tank must not be within 10m of controlled water (this includes watercourses such as rivers, streams, ditches and also septic)
- The tank must not be located where a spillage could run into an open drain or loose fitting manhole cover (this includes sink wastes and domestic drainage systems)
- The tank must not be located within 50m of a well (even disused), borehole or spring.
- The Tank must not be located over hard ground that could enable a spillage to run off to reach controlled water (so if the tank was located at the top of a concreted driveway and it failed, then could the oil travel down the drive to the storm water drain at the bottom of it?)
- The tank doesn’t supply heating oil to a building other than a single family dwelling (e.g. office or other commercial property, multiple occupancy buildings)
- The tank isn’t located within a Ground Source Protection Zone 1 (this can be checked by visiting the Environment Agencies website)
- The tank is not in an area where regional regulations require mandatory bunding – for example Wales.
This is just a few examples if you are in doubt to whether you can have a single skin tank please feel free to discuss this with our team.
