Independent Bulk Materials & Water Engineering Consultancy

Professional Oversight of Engineering Projects

Solidus & Aqua is an independent engineering consultancy and technical think tank specialising in bulk materials handling and water infrastructure systems.

With over 30 years of engineering experience and global project delivery exposure, we bring disciplined technical judgement and practical insight to complex materials and fluid transport challenges.

We support asset owners, operators and EPC contractors across the UK, Europe and Sub-Saharan Africa in delivering infrastructure that performs reliably, efficiently and sustainably.

Operating independently of equipment manufacturers, our focus is not product supply — it is engineering clarity, system integrity and long-term operational performance.

Alongside consultancy services, Solidus & Aqua functions as a focused technical think tank, continually evaluating emerging technologies and environmental pressures to ensure that engineering decisions are informed by both operational reality and forward-looking insight.

We deliver solutions that work in practice — not just in specification.
