What Hydrotec Consultants does

Hydrotec Consultants Ltd is a privately held specialist engineering consultancy headquartered in Yeadon, Leeds, United Kingdom, focused exclusively on hydraulic structures for the water and wastewater industries. The firm serves two primary vertical segments: water and wastewater utilities (including Thames Water, Severn Trent, Yorkshire Water, United Utilities, Scottish Water and Wessex Water) and engineering consultancies and contractors (including MWH, Thames Tideway, Degremont and Black & Veatch). Project delivery spans the UK, Europe, the Middle East, Asia Pacific, the Americas and Africa. With a headcount of 1-10 employees, Hydrotec operates as a focused expert practice rather than a scaled consultancy.

The company's core technology stack combines a physical hydraulic scale modelling laboratory with Computational Fluid Dynamics (CFD). Physical modelling uses scaled structures built in clear acrylic on timber frames to reproduce full-scale effects including velocity distributions, air entrainment, vorticity, pre-swirl rotation, hydraulic gradients and losses, and solids transport. CFD applies numerical solvers on supercomputers to simulate fluid interaction with defined boundary conditions, supporting both 2D and 3D dynamic analysis. Specialised application areas include drop shaft analysis (tangential vortex drops, cascades, scroll intakes) and pump intake analysis (vorticity, air entrainment, pre-swirl, velocity distribution). Services span preliminary conceptual design, independent hydraulic design auditing, and detailed hydraulic design consulting across pumping stations, inlet works, flow distribution and mixing chambers, storm tanks, reservoirs, rivers and CSO chambers.

Hydrotec operates as a B2B professional services firm generating revenue through project-based consulting fees for physical modelling, CFD analysis and hydraulic design services, delivered via direct enterprise sales relationships with utilities and engineering firms. Pricing is not publicly disclosed and is negotiated per engagement. Go-to-market relies on a company website showcasing capabilities and a direct client engagement model targeting capital water infrastructure projects and operational asset optimisation. The value proposition centres on predicting full-scale operating conditions to reduce reactive maintenance exposure (cited as up to 90% reactive at some sites, with unplanned maintenance costing 50% more than planned), and on de-risking new-build and retrofit hydraulic designs prior to construction.

Functional benefit

Products and services

• Physical Model Testing Physical hydraulic scale modelling service that accurately reproduces full-scale hydraulic effects such as velocity distributions, air entrainment, vorticity, and pre-swirl rotation to assess pump performance, general hydraulics, and solids handling across pumping stations, inlet works, flow distribution and mixing chambers, reservoirs, rivers, and drop shafts. Models are constructed in clear acrylic on timber frames.
• Computational Fluid Dynamics (CFD) CFD modelling service using numerical methods and algorithms executed on supercomputers to solve and analyse problems involving fluid flows. Provides 2D and 3D dynamic modelling for complex hydraulic assessments across pumping stations, inlet works, flow mixing and contact tanks, storm tank cleaning, and rivers.
• Preliminary Conceptual Design Expert guidance and advice during the conceptual design phase of hydraulic structures, with progression to detailed development and optimisation through physical or CFD modelling. Early involvement is intended to expedite the design phase by reducing the extent of testing and analysis required.
• Independent Hydraulic Design Independent hydraulic auditing of proposed designs to identify areas of potential concern that could adversely influence the operation of full-size applications. When used in conjunction with either CFD or physical modelling, the service provides confidence in the system prior to construction.
• Detailed Hydraulic Design Advice on detailed hydraulic design covering all aspects of hydraulic systems including flumes, flow control devices, weirs, baffles, operating philosophies, cleaning cycles, pump cycle times, and general control procedures.
