Field Factors enables purification and storage of rainwater with the use of their Bluebloqs circular system. It can be applied in an urban environment like that of the Sparta football club in Rotterdam. The system offers the advantage that it takes up very little space. The water can be recycled during dry periods several months later.
Commercial director Wilrik Kok (36) talks about the innovative character of Field Factors.
How did the idea for Field Factors come about?
We all have a background in spatial planning, including at TU Delft, e.g. landscape design, architecture and industrial design. We saw that rainwater was often just being drained off while there was a demand for water for irrigation and cooling later on. This awareness existed even before the very dry periods of recent summers. As an example, that you could take advantage of this opportunity when a sewage system gets replaced. Field Factors wants to manage water differently and in a natural way.
What kind of things does it do?
The application of Bluebloqs is key. It is a compact, green system that collects and purifies 95% of the rainwater through biofiltration in conjunction with underground storage technology. This allows parks to remain green and sports fields can be kept in optimal condition every season. The water is good enough for industrial use too.
For example, at the Sparta stadium in Rotterdam the rainwater drainage system has been disconnected and is being prepared for recycling which happens in four steps. Rainwater will be collected in the stadium and at the nearby square. Together these cover an area of six football pitches in total. This water will be collected in a reservoir underneath one of the Cruyff Courts (mini football fields made of artificial grass in public spaces, ed.) This polluted water is then decontaminated using plants and sand. The purified water is stored in an underground water reservoir. W hen it’s hot This water can be used by children who are playing to cool them down. As well as for watering the Sparta sports field. Flooding is prevented during heavy showers. The square is greener and the football club has a sustainable water supply.
Location, location, location
It is a comprehensive approach, from the beginning to the end and where maintenance is concerned. We base our work on the location and use it to make a quick scan. What is the ground underneath like, and is decoupling possible? We then make a draft sketch to offer an idea of what is feasible and what it will cost. If the interested party agrees, we work on it up until the specifications phase when a contractor can take over and get to work. After it is completed, we remain involved in monitoring and maintaining it.
What makes your company stand out?
What’s special is that Field Factors is busy with the design of the water system at a very early stage, but also remains involved afterwards. That usually doesn’t happen. Construction of water drainage systems and their management are usually carried out separately from each other. Aside from that, the actual physical integration is unique to Bluebloqs.
How have the reactions been so far?
When we first started out, the problems surrounding dry weather were not yet apparent and it was really a matter of first seeing, then believing. In retrospect we did choose the right momentum as it is very topical nowadays. Up until now, we had primarily been working on unique locations and pilot projects which can also serve as an example for regular application of our system in the vicinity.
What has been the biggest obstacle?
Initially the local community – even people out and about on the streets -was reluctant and they found it difficult to accept the way it works and is built. Or even that a water purification system can actually be used in a public space. Usually these are hidden underground, but we have deliberately opted for visibility. And by that I specifically mean the location. That in the first instance, you pick a particular place where many people flock to, and use that for the Bluebloqs Biofilter.
What have been the highlights?
That was last year at Sparta in Rotterdam. Then you’ve built something and it’s exciting to see if it works properly. A lot of water is being processed at that location. So, if things go wrong you’re bound to get a lot of unwelcome attention. And in October we won €100,000 as finalists of the Green Challenge. This is an annual, international sustainability competition held by the Dutch Postcode Lottery.
What can be expected in the coming year?
We are racing to build five systems. One of these is definitely going to succeed, but all lights are green for the other four projects as well. Besides that, we are expecting an answer from our patent application. And we are launching a new product, an extension of the Bluebloqs product line. A rain garden, so to speak.
Where will Field Factors be in five years’ time?
We will have grown and have a team of fifteen people. By that time we will have fifty systems operational in The Netherlands. We will also have shifted our operations to Spain. Our director Karina Peña is in fact a Spanish speaker. Spain is likely to suffer more and more from increasing drought as time goes by.
