WJ UK

WJ UK delivers specialist groundwater management and well drilling services from its base in Kings Langley, supporting construction, infrastructure, utilities and energy projects across the UK and internationally.

Its capabilities include well drilling, dewatering and groundwater control, pumping tests, groundwater monitoring, water treatment and remediation, and ground-source energy systems. The team provides support from early design and feasibility through installation, commissioning, monitoring and maintenance, with drilling solutions tailored to ground conditions, access constraints, well dimensions and pumping requirements.

For well drilling projects, WJ works with water-supply wells and arrays of dewatering or monitoring wells, using rotary, cable percussion and down-the-hole air-hammer techniques where appropriate. Its ground-source energy work includes feasibility studies, well installation, testing, monitoring and maintenance for open-loop heating and cooling systems.

The company works with major construction and infrastructure programmes as well as commercial, industrial and public-sector clients. Its published project experience includes rail, tunnels, water works, hospitals and other complex developments, while its wider profile also refers to residential groundwater-control work.

Clients can draw on a technically focused team combining hydrogeological understanding, practical engineering and modern drilling equipment. The official website also highlights BDA-audited drillers and a complete design, installation and maintenance approach.
