## Summary

Southern Water Services Limited, a private utility company based in Worthing, UK, is undertaking a procurement process titled "Data Modelling - Request For Information (Southern Water)" within the services industry category. This process is focused on enhancing Southern Water's modelling capabilities to aid decision-making for its PR29 programmes. The procurement is currently at the planning stage, with a milestone for conducting a Request For Information scheduled for 31 October 2025.

This tender presents opportunities for businesses specialising in digital mapping, data management, and design-modelling services to contribute to significant strategic developments at Southern Water. Particularly suitable for small and medium-sized enterprises (SMEs), the contract offers a chance to engage with Southern Water in enhancing their strategic capabilities and achieving environmental and financial performance improvements. Companies in the utilities sector with expertise in advanced data modelling and scenario testing capabilities will find this an advantageous opportunity to assist with Southern Water’s capital maintenance and process upgrade programmes, fostering long-term business growth and establishing collaborative industry relationships.

## Notice

At Price Review 2024, the development of Southern Water's modelling capability has supported the articulation of realistic, affordable and future proof long term business strategies (e.g. Bioresources) to mitigate upcoming threats & seize opportunities with the view to improve the company's financial & Environmental performance. This has been achieved mainly through the provision of process modelling (e.g. sludge transport, masse and energy balance, asset replacement forecast) and scenario testing capability (e.g. testing of impact of varying costs forecast, change in treatment capabilities). This has been the basis of evidence supporting the strategies developed by Southern Water's Asset Strategy & Planning team. Southern Water is looking at developing this capability further to support the decision-making process of key PR29 programmes. In AMP8, it is also Southern Water's aim to use modelling capabilities to assist with the planning, impact assessment and testing of constraints of tactical (within AMP) programmes implementation (e.g. capital maintenance, upgrade of processes & plants)
