About TakaDu 

TaKaDu provides a comprehensive SaaS Central Event Management (CEM) solution based on smart analytics that enables water distribution utilities to manage their water network efficiently and intelligently, thus empowering them to reduce water loss, improve operational efficiency, and increase customer satisfaction.

As a smart utility, there are undoubtedly many key performance indicators (KPI) that you’re already tracking in terms of your DMA performance, to measure efficiency and compare with your goals.

But there are two values that are often overlooked, that are key to developing effective strategies for proper non-revenue water (NRW) management, and prioritizing activities. And they are Technical Efficiency and Infrastructure Leakage Index.

Technical Efficiency represents a gross estimation of the percentage of the total water supplied to a sector over a specific period of time, that is not wasted as losses (apparent + physical). While the Infrastructure Leakage Index, proposed by the International Water Association, is a unit-less performance indicator of real (physical) water loss from the supply network.

Each reveals important information about the status and trends in your water network. The first one is relatively simple to ascertain, and the second one is more complex, but both are well within the capabilities of any utility.

By understanding these KPIs over time, with the right calculations, and the consistent visibility provided by the TaKaDu CEM, utilities can significantly improve prioritization activities in the field, better plan campaigns, better detect hidden leaks, and reduce overall water loss.

To help utilities optimize these valuable KPIs, we’ve written an in-depth article covering:

  • The formula for calculating Technical Efficiency and Infrastructure Leakage Index
  • Practical illustrations of how these calculations work – from real utility logs – including the insights revealed
  • Benefits and limits of each KPI
  • Concrete examples of activities that can be improved (and how) by regularly tracking your Technical Efficiency and Infrastructure Leakage Index

For all the details, including tips and a succinct walk-through of all the steps involved, we welcome you to download our latest article in full. It’s a great way to get more out of your CEM, but more importantly, your water network.

Addressing Water Scarcity and Climate Change: A Global Challenge

Water scarcity and stress, exacerbated by climate change, are pressing global issues with far-reaching implications for sustainability. As the world becomes increasingly thirsty, compounded by the growth of the global population, the problem of water scarcity is set to intensify. Currently, an estimated 2 billion people reside in water-stressed areas, and projections for 2040 indicate that 44 countries will face “extremely high” or “high” water stress levels.

See what’s happening in your network’s blind-spots with these 3 predictive management steps

Water loss reduction is often the primary motivation for investing in a central event management (CEM) solution. And its benefits are felt across the board, in terms of water, cost, and time savings, not to mention overall customer service.

But despite its name, central event management is about far more than managing events; it’s also about improving the network and monitoring infrastructure.

The path forward: smarter, data-rich water management

Water management technologies have evolved dramatically since the days when listening sticks were about the only leak detection device available to utilities. And today, water management is about far more than leak detection. In fact, it’s no longer even about just water management; now it’s increasingly about data technologies and smart water management.

So, why is smart water management needed? And where is it going from here?
