JFC

JFC manufacture a broad range of polyethylene tanks including potable and non-potable water tanks, septic tanks, pump chambers and bunded oil tanks. Their tanks are widely used across agricultural, domestic and commercial off-mains applications throughout the UK and Ireland. The range spans small header tanks right up to large-capacity water storage units.

Yes, JFC's potable water tanks are manufactured to WRAS standards and are suitable for storing wholesome water. Always check the specific product listing to confirm WRAS approval before use, as JFC also produce non-potable tanks for rainwater harvesting and general water storage. Using the wrong tank type for drinking water isn't just risky — it can also breach water byelaws.

Some JFC tanks are designed for below-ground installation, but many in the standard water storage range are intended for above-ground use only. Below-ground tanks need adequate wall thickness and structural design to withstand ground and groundwater pressure, so check the specification carefully. If you're unsure, ask us to confirm whether a particular model is rated for underground installation before you dig.

For domestic water storage, work out daily usage (roughly 150 litres per person per day is a common planning figure) and size for at least one to two days' backup supply. For septic tanks, sizing is based on the number of bedrooms or occupants and is set out in Building Regulations Part H. Agricultural and rainwater harvesting tanks are usually sized against catchment area or livestock numbers, so get in touch if you need help working out the right capacity.

JFC septic tanks and treatment systems are designed to meet relevant British and Irish standards, but compliance also depends on correct installation, siting and discharge consent. Since 2020, septic tanks discharging to a watercourse in England generally need upgrading to a full treatment plant, so check with the Environment Agency or your local authority on discharge requirements. We can advise on which JFC product suits your site conditions, but final regulatory approval rests with the relevant authority.

Larger JFC tanks are bulky and typically arrive on a curtain-sided or flatbed lorry, so make sure there's clear vehicular access and enough space to manoeuvre and unload at the delivery point. You'll usually need suitable manpower or lifting equipment on site, as drivers generally can't unload heavy tanks alone. Have your base or excavation prepared in advance so the tank isn't left standing longer than necessary.
