Case Studies Water

South West Water, United Kingdom

South West Water is a U.K. water and wastewater service provider serving a population of c. 1.7 million in Cornwall, Devon, and parts of Somerset and Dorset. Since 2016 it has also been providing water services in the Bournemouth Water region to a population of c. 0.5 million.

In order to continue to provide reliable, high quality drinking water and waste water services throughout these areas, South West Water needed to review its wide asset base and invest in its infrastructure.

To do this, they adopted Arcadis gen’s Enterprise Decision Analytics, a solution that allowed them to better manage their assets and maintain their quality service.

Highly visual modelling outputs for better decision making

Reduction in total expenditure investment to meet same service requirements

Ability to create different investment scenarios and make comparisons

The Challenge
South West Water operates within a region surrounded by some of the UK’s most important heritage coastlines and a National Park, making it a popular destination for tourists all year round. As a result, ensuring excellent customer service and that the natural environment is preserved is a priority. In addressing these, they required a solution that would help them create cost-effective investment and maintenance strategies across a range of buried infrastructure assets.

The Solution
In partnership with South West Water and its suppliers, we provided a solution using our Enterprise Decision Analytics (EDA) platform. Using modelling techniques to predict probability of failure, consequence and risk, the models were then optimised within the EDA platform. This provided South West the ability to ask a set of “what if” investment scenarios with the key objective to minimise whole life cost.

The EDA system also used deterioration profiles to forecast the long-term performance of their assets.

The Result
After deploying EDA, they were able to gain better insights from their assets and analyse different investment scenarios. All of this information created more efficient processes and higher levels of confidence when making critical decisions.

By understanding system dynamics, the platform was able to evaluate all the possible pipe replacement benefits against the consequence of non-replacements. Leakage detection and pressure reduction was also considered to provide a holistic total expenditure view.

"In support of our PR19 business plan we have evolved and grown our coverage of EDA asset models to include all of our water and wastewater below ground infrastructure. Furthermore, we have explored innovative new ways to use EDA such as in support of our metering strategy.

The advanced optimisation and excellent visualisation of EDA ensures that the investment decisions proposed provide best value to our customers and ensures long term asset resilience. We really enjoy working with Arcadis Gen and the innovation that EDA brings to our decision making supports our digital vision for the future."
