Water infrastructure management and modelling

Providing a complete hydraulic and infrastructure management solution to enhance current and future water network performance.

Proactive and reactive infrastructure management, and associated modelling, to understand the hydraulic and water quality performance of your network, from water treatment work outlets to customer taps. The insights we provide facilitate contingency planning, maintenance, and investment decisions. Our holistic ‘source to tap’ approach, which encompasses innovative data analysis tools, provides evidence-based solutions to mitigate current and future risk.

Everything we do is linked to the customer to ensure you proactively manage your targets, whether that’s internal performance commitments or regulatory Outcome Delivery Incentives (ODIs), whilst building resilience within your networks.

Our evidential, auditable, and holistic infrastructure management processes align with both your corporate data and the data you deliver to the regulator.

We build or update network models to identify the root cause of performance issues and subsequently design interventions to improve performance in the long term, complete with evidence base. Our data supports your cost / benefit analysis for your investment proposal.

Our value

Our in-house proprietary, SMART, integrated modelling and GIS data warehouse systems makes model building and maintenance affordable, efficient, and integrated.

The SMART system is compatible with all GIS formats and modelling software applications.

Over 130 combined years water infrastructure management and modelling experience (inc. 35 years direct for Water Companies) from nine in-house experts.

SMART system: Greater accuracy = greater benefits

A key element to determining whether a given set of hydraulic models is fit-for-purpose, and where improvements could be made, is the deployment of our SMART model audit tools.

The SMART modelling system is an integrated modelling and GIS data warehouse with significant model build time and costs savings (up to 60%) making it affordable even for small projects. It is compatible with all GIS formats and modelling software applications and has immediate integration with other water infrastructure related projects.

There are four stages in our audit process

The process contains a decision point, after audit stages 1 and 2, as these stages are designed to identify unfit models at the earliest possible opportunity with the minimum amount of effort and cost expended.

As all models can be audited in a consistent manner against the exact same compliance elements, scoring rules can be applied consistently across the entire programme and a cost per entire rebuild vs maintenance can be generated.

How we can help

Water network modelling

A network model is a computer-based representation of the hydraulic capacity, demands and dynamic controls present in a water network. It represents actual network hydraulic conditions at regular intervals throughout the day.

It is used to identify network deficiencies which would then stimulate scenario modelling and undertake scenario modelling projects.

*System knowledge and real data analysis is a pre-requisite to any successful model-based study

What benefits do hydraulic models provide? (Model accuracy dependant)

  • Analysis of network performance under current, peak, and forecast demand conditions
  • Identification of the root causes of capacity constraints and other performance issues
  • Support tool for network operations
  • Optimisation of system controls e.g. pump scheduling, pressure management
  • To support the decision-making process as an evidentiary investment tool

Network modelling services include:

  • Model build and calibration
  • Model maintenance
  • Model conversion
  • Model audits
  • Surge modelling
  • Model build specification development
  • Discolouration risk modelling
  • Water quality modelling
  • Leakage ‘hot spot’ modelling
  • Pressure optimisation modelling
  • High velocity mains cleaning designs
  • Trunk main conditioning modelling
  • Growth forecast modelling
  • Tankering and backfeed contingency modelling

Water infrastructure design and maintenance

We provide a number of services to aid you in the optimum design of new water network assets. Our dedicated, experienced team of network engineers deploy calibrated network models, and significant engineering judgement, to devise the most efficient, effective, and resilient configuration of network assets whatever the constraints may be.

In addition, we will deliver a suite of associated, follow-on network interventions, from mains conditioning activities to planned preventative maintenance schedules, to enable the effective operation of the assets in question and meet future challenges pertaining to growth and climate change. This tried and tested approach to whole-life network management also ensures you benefit from the total possible lifespan of your assets whilst ensuring customer performance targets are met or exceeded.

Asset health and optimisation

This service focuses on delivering reliable and resilient water services to current and future customers. We review your asset base, at the granularity of individual assets, to develop a bespoke, holistic ‘source-to-tap’, risk-based set of measures with robust and transparent methodologies. Outputs are evidential, auditable, and quantitative and, as a result, resilience and investment can be linked to customers and regulatory performance targets.

Our services in this area include:

  • Source to tap assessments
  • Holistic zonal studies for regulatory target-based investment
  • Integrated network management studies
  • Asset health assessments
  • Risk and consequence analysis
  • Root cause analysis
  • Critical asset assessments
  • Strategic trunk main assessments
  • Evidence / risk-based investment plans
  • WRMP source to tap transmission assessment
  • Network criticality assessments
  • ‘Individual asset’ & ‘asset systems’ resilience assessments
  • Pressure transient risk assessments
  • Operational maintenance: optimised programme development
  • Operational performance reviews
  • Total system energy cost optimisation
  • Complex data analytics
  • Process and software support
  • GIS network connectivity assessments
  • GIS-based risk and resilience asset management reporting
  • Asset and zonal level contingency plans
  • Database development
