Temporary R31 Potable Water Infrastructure for Critical Asset Maintenance

Storage Resilience at the Speed of Operations and the Cost of Rental

Butek-Portstoken provides turnkey temporary potable water infrastructure to UK water utilities, delivering Regulation 31 compliant storage, pumping, and network support for planned maintenance, operational storage shortfalls, emergency resilience requirements, and reservoir refurbishments.

From design and delivery to disinfection, commissioning, and full site reinstatement, we manage the complete lifecycle of every deployment. One contract. One point of contact. Full accountability throughout.

Low-Carbon & Reversible

Concrete-free, reusable infrastructure designed to minimise embodied carbon, reduce site disturbance, and avoid permanent construction wherever possible. Fully recoverable, re-deployable, and engineered for rapid reinstatement.

Security by Design

Every deployment subject to a dynamic SRA's aligned to NPSA Critical National Infrastructure principles. A temporary installation carries the same security obligations as the permanent asset it replaces.

Full Lifecycle Delivery

Design, delivery, installation, disinfection, commissioning, telemetry, monitoring, decommissioning, and site reinstatement — all under a single Butek Portstoken contract.

Reg 31 Compliant

All water-contact materials certified to Regulation 31. Every installation designed for potable water from the outset — tanks, liners, pipework, and fittings. All aspects of each build are WQ approved in advance.

Temporary water infrastructure carries permanent responsibilities.

Water companies operating under AMP8 face mounting pressure to maintain supply continuity while accelerating capital delivery. The Cunliffe Report is clear: the sector must do more with constrained capital, and faster. Planned outages, operational storage shortfalls, emergency resilience requirements, and reservoir refurbishments all require temporary infrastructure that meets the same standards as the permanent asset it supports — and that can be deployed, operated, and removed within compressed programme windows.

Butek Portstoken was established specifically for this environment. Our rental model converts upfront capital expenditure into flexible operational spend, transferring infrastructure ownership and deployment risk away from the water company while providing the speed, compliance, and programme certainty required for modern asset management.

Lower Carbon by Design

Traditional temporary storage solutions can become permanent construction projects — involving reinforced concrete, piling, extensive excavation, and long-term site impact.

Butek Portstoken takes a different approach.

Our systems are designed around reusable modular infrastructure, concrete-free installation methods, reduced heavy plant requirements, and full recovery at project end. In most cases, installations can be delivered without permanent foundations or irreversible civil engineering works.

Because equipment is redeployed repeatedly across multiple operational cycles, the embodied carbon associated with manufacture is distributed across many deployments rather than attributed to a single permanent asset build.

For water companies operating under AMP8, this provides a lower-carbon route to operational resilience, asset maintenance, and temporary treatment support — without creating stranded infrastructure or unnecessary permanent legacy.
