Leakage Intelligence Decision Support: LIDS

With ever increasing environmental pressure, including rising temperatures, increased water scarcity and mindfulness around waste-reducing value chains, the focus on reducing leakage and non-revenue water has never been greater.

Water supply companies are under increasing pressure to reduce leakage in their networks whilestill providing good value to their customers. The roadmap to sustainable leakage reduction is defined by complex interactions between a wide range of operational and capital interventions.

A successful leakage management strategy needs to consider financial constraints, asset and operational performance, regulatory requirements and available innovation options. The optimal approach must blend the individual and combined benefit of all possible interventions, as well as reflecting their relevance to local performance and asset conditions.

Business Modelling Associates (BMA) are working with Water Utilities to deliver a data-driven,holistic solution to analyse, visualise and optimise their end-to-end leakage management processes. Our solution is driving sustainable improvement in leakage performance, whilst providing a powerful link between operational management, long-term capital investment and innovation.


With ever increasing environmental pressure, including rising temperatures, increased water scarcity and mindfulness around waste-reducing value chains,the focus on reducing leakage and non-revenue water has never been greater.For example, the UK Water Services Regulator (OFWAT) requires the UK Water Sector to reduce leakage levels by an average of 16% over the next 5 years(April 2020 to April 2025). Many companies have gone further, committing to a 50% reduction in leakage by 2050.

These requirements, combined with the need for companies to both deliver water at a fair cost to their customers and value to their shareholders, is an extremely challenging task. To rise to this challenge water companies must ensure the alignment and optimisation of their leakage operations, capital investment and targeted innovation spend, reflecting a complex backdrop of regulatory, financial and organisational constraints.

Solution Approach

LIDS is a single solution which aligns and optimises capital and operational leakage management activities over a 5-year+ period. The solution:

  • ensures capital programmes, operational resourcing and operational performance management are coordinated in an optimal way; and
  • provides enhanced assurance of future leakage performance, ensuring the relationship between in-year performance and multi-year targets is reflected in the optimal intervention plan.

Robust and rapid quantification of the benefit of innovation ensures that the Innovation strategy is both targeted and aligned to current and future performance, operational needs and the overall leakage strategy.

At the heart of the solution is a detailed leakage management model which represents a wide range of mechanisms - both conventional and innovative - by which operational activities and capital schemes will contribute to leakage reduction.

“The Leakage Intelligence Decision Support (LIDS) solution is a real step forward, enabling a truly whole systems approach to leakage management decisions to be taken with confidence.”
