Since the early 90s, we've been involved in wastewater network computer modelling. We have standardised our processes and specifications over many years and pass on the savings in time and cost to our clients. We deliver efficiencies through constantly developing new tools and processes to improve our services. We have automated many of our processes to ensure efficient outputs and we utilise our internal project and programme management systems to ensure key milestones are achieved.
We have built and verified numerous hydraulic models, in varying degrees of complexity and size, with different drivers, project focus and catchment specific requirements. Our internal modelling procedures are regularly reviewed to ensure we utilise best practice. Our modellers ensure cross-fertilisation of new ideas and best practice throughout.
Whilst we often undertake new model building work, we also are required to adapt models from other organisations for future use. We have robust procedures in place to do this, assessing the condition of an existing model and highlighting any areas for improvement to suit the planned work and identify risks associated with this. This allows the client to make informed decisions on, for example, future investment in survey work.
Typical work packages
- Existing model review – identification of data gaps and risk identification
- Identification/planning of survey requirements (eg manholes, CCTV including sonar surveys to determine sewer silt depth, topographical, flow, impermeable area)
- Procurement of survey work including specification, on site liaison/management and interpretation of survey data
- Liaison with landowners, highway authorities and other third parties including securing access permissions
- Model verification, model improvements and upgrades
- Identification of catchment needs, optioneering and solution modelling
- Water quality and river impact modelling
