H2O Consultant’s projects are coordinated by a management team which combines in-depth 'hands on' experience, and a consistently positive approach, to provide innovative cost efficient engineering solutions on our projects.

We minimise the risks of time and budgetary over-runs on our projects by planning and implementing accurate critical path documentation, and having a thorough knowledge of authority approval procedures.
We achieve quality in our designs by incorporating environmentally aware design, and use of the latest proven materials and production methods.

We can be instrumental in the smooth running of project by presenting authorities with preliminary design concepts to highlight areas of potential difficulties, and therefore find alternative solutions at the concept stage.

Our strategic aims:

  • To provide our customers with water and wastewater services which meet Regulatory requirements, and to contribute to the protection of the natural environment.
  • To identify, and be responsive to the needs of domestic and non domestic customers, and to deliver water and sewerage services at the lowest possible cost.

We operate as a sole source supplier of services:

  • Complete construction support from pre-bid consultation through design, construction, and monitoring.
  • Responsiveness to changing conditions, construction methods, and schedules.
  • Geo-technical, geo-civil, and structural engineering designs.
