What we do
Water treatment

Backed by decades of expertise in engineering, design, and science, we ensure clean, compliant water management on every site through an agile, modular approach. From sediment control to chemical dosing, we operate across sectors and countries.
Our small footprint, high-performance solutions are designed and assembled in Wales, then deployed and installed by our expert teams wherever they are needed across the water, infrastructure, and industrial sectors.

What we do
Water handling and storage
The Workdry Group delivers comprehensive, mission-critical water handling and storage solutions for every scenario — from sewer bypasses, network maintenance, and flood response to short-term abstraction, seasonal demand, and semi-permanent installations.
Our sister company, Selwood, operates a high-performance fleet that manages everything from foul and surface water to viscous sludge. Fully engineered storage systems integrate pumps, tanks, pipework, manifolds, and control systems into a seamless, turnkey package. All solutions are designed, installed, and commissioned by expert engineers.
With real‑time remote monitoring, 24/7 emergency support, and full environmental compliance, we help utilities and contractors maintain flow, protect assets, and respond fast — reliably moving and storing fluids with minimal disruption and maximum peace of mind.
