Condensation puts water in the tank, the water feeds the microbial bloom known as diesel bug, and the result is a dark, hazy fuel full of sludge that clogs filters and injectors. Cold weather adds a second failure mode. As diesel ages and the temperature drops, wax crystals form and gel, and old fuel gels sooner than fresh. A tank that ran last summer can refuse to flow the following winter. The disposal side is the paperwork and the destination. The diesel is routed to a licensed facility, processed or destroyed, and logged on a transfer note so you can show it was dealt with lawfully. The disposal end matters most for compliance. Once lifted in Llandeilo, the fuel is routed to a licensed facility for recovery or destruction, and the paper trail is the point: your duty of care is discharged by evidence, not assurances. ## Local Welsh old diesel disposal in Llandeilo: the facts Fuel | Old diesel | Service | Collection and licensed disposal | Council area | Carmarthenshire | Postcode districts | SA19 | Why it degrades | Oxidises, drops sediment and grows diesel bug where water is present | Typical sources | Farm tanks, generators, plant, HGVs, boats, bowsers, bulk stores | Classification | Hazardous waste — waste transfer note issued | Regulator | Natural Resources Wales | Typical cost | Quoted per litre or per job | Attendance | Collected and disposed of under licence | Helpline | 01295 380724 | ## Where old diesel comes from around Llandeilo In Llandeilo the usual sources of old diesel we collect and dispose of are boats and marine tanks out of the water, and construction plant demobilised from a finished site.

A registered carrier attends home, farm, depot, marina and commercial sites, pumps out the old diesel and issues a waste transfer note on site. **Can contaminated diesel be cleaned instead of removed?** Polishing can recover lightly contaminated diesel, but heavily bugged or watered fuel is usually removed and the tank cleaned.

Give us the volume in litres and the access and you get a price and a slot before we travel. **Do you clean the tank as well?** We remove the fuel and can arrange a tank clean where the bug or sludge means the vessel needs it before reuse.
