No more black-box software solutions for leak detection

Giving Water Knowledge
HULO’s algorithms provide water utilities with know-how about their water network. Together, we detect, localize and quantify leaks in the very early stages. By tailored solutions the knowledge stays at the client’s side.

Can we do it together? better? faster? cheaper?


Water is a scarce resource.

Did you know that water will be a scarcer resource if we do not act quickly? 
You, I, we can contribute to the solution.

60% of water is lost world wide.

The U.S. Environmental Protection Agency (EPA) estimates that up to 60% of water worldwide is lost to leaky pipes and that, in the U.S. alone, an average of 700 water main breaks occur every day.

€20,000,000 is lost every single day.

Wasted water costs us EUR 20 million globally each day. That's in addition to the costs of repair and replacement...

50% of all people might experience water scarcity by 2025

Unicef acknowledges that we need to improve the efficiency of our water resources to prevent this from happening...

Do you recognise these challenges?

We have a lot of leaks in our network. How do we reduce our non revenue water?

Placing sensors in our network can be expensive. How do we design and/or optimize our DMA?

We get notifications of customers about leaks. How can we prevent reputational damage of our company?

We have leak detection software, but it is based on historical data. How do we reduce the false positive leak alarms?

We do detect leaks, but existing leaks cannot be found. How do we also get the smaller leaks visible?

We want to repair the biggest leaks first, but where are the biggest leaks?

What's the difference?

HULO versus current leak detection software

Current solutions

  • High upfront costs
  • High start-up time
  • Historical data required
  • Correction for false positives
  • Commercial approach
  • Black-box solution


  • Low upfront costs
  • Low start-up time
  • No historical data required
  • No false positives
  • Most recent research
  • Together with customer

Our services

Real-time leak detection

With a unique approach HULO can detect leaks in the very early stages on a real-time basis. No historical data is needed to detect leaks. Plug & play!

With hydraulic models, HULO will localize the detected leaks as accurate as possible.

‘We want to repair the biggest leaks first!’, a quote we will not forget. With HULO we are able to determine the leak volume. Isn’t that nice?

A DMA can be expensive to implement. HULO’s algorithms know exactly where to place sensors most efficiently, taking into account all purposes.

DMA optimization

The current DMA design might not be the best suitable for you. HULO’s DMA doctor will check if the DMA design can be optimised. Schedule your appointment with the doctor now!

Our story

HULO’s journey was inspired by Acquaint’s journey. Together, we strive for a reliable water infrastructure, worldwide. HULO’s mission is to provide a globally affordable solution to improve water supplies and to reduce NRW by doing it the smart way, ’together’ with our clients. We believe that developing knowledge together with our clients is most beneficial for a sustainable and future proof water supply. 

A lot of black-box and off the shelves solutions are offered these days to the water sector. With these solutions, the knowledge about what is really happening stays at the commercial companies selling these smart algorithms. HULO is different. We do this by developing smart algorithms, together with independent research institutes. These independent research institutes continuously receive questions from the water companies and therefore help us to specify these needs and develop the solutions for these needs. 

We develop algorithms to design a DMA and to detect, localize and categorize leakages. Since we do this based on the needs of our customers, it allows us to make a specific solution for every client. This solution works in the system of the client, which allows them to understand it and learn from it. 

HULO gives water knowledge, straight from the capital of water technology: Leeuwarden, the Netherlands

From research to practice

In order to stay innovative and to continue giving knowledge, HULO is in touch with research institutes. Testing new ideas will lead to innovative products, which benefit the customer. In the end it is most important that the customer learns from it, instead of only using it. We only assist.
Besides research institutes, HULO is continuously looking for partners. Together we acquire and give knowledge.
Creating knowledge


What we find most important is that all the created knowledge will be acquired by the client. In order to do this, we need commitment from our clients. If we want to learn together, we need to create it together. In order to create the best suitable solutions, we always work together with the client to meet their specific needs. No more black-box off the shelve solutions. We want to make it work.

HULO gives water knowledge.
