We have signed a contract with Drammen municipality for a new research and development project where we also have the following companies as subcontractors for us. These are: -USN, University of South-Eastern Norway -Kingspan Water & Energy AS, Norway -Kjeldaas AS, Norway -Wapro AB, Sweden
This is a very interesting project where the final goal is to increase the capacity of a 1 km. long stormwater culvert from approx. 5 m3 per second to 13 m3 per second. (There is a lot of water, like a small river that will run through the city).
We have also signed an agreement with Bærum municipality for a very challenging project. They want us to develop the system that will make a new pressure pipe work with siphonic drainage.
Other emerging projects
We are also working with several other municipalities and cities on other interesting projects, but we have not entered into the agreements yet.
Patents and cooperation
We have already taken out patents in several countries and are therefore looking for partners in other countries to collaborate with us. What has been working well for us in Norway is to work directly with the municipalities to determine how to solve the problem. We then subcontract out the actual construction, supervising the work to be sure that everything functions properly. Generally, we like to have a good relationship with pipe lining companies.
Increasing of capacity
How large a capacity increase we get will vary from facility to facility. In the Solveien, Asker project, the water flow increased in the PE200 pipe from maximum 7 l/s by gravity to maximum 44 l/s when the Aiwell Water valve made it switch to siphonic drainage. The stretch is short, only 400m, and with an 8m difference in elevation. This yielded 6.2 times more water through the pipe. In Drammen, the length is approx. 1,000m and the increase in elevation is approx. 40m. Here the increase in capacity is only 2.6 times greater with siphonic drainage. This was perfectly adequate for the challenge there. So, depending on the conditions, results will vary. Good projects that generate huge savings are crossing of railways and roads because these are short distances, and the operations can be performed quickly without disturbing the traffic at all. In these projects, the usual costs of digging are high. However, with Aiwell Water`s siphonic system, the potential for capacity increase is great, even if the difference in elevation is small. That is because of the short distance of the pipe. Often a 50% increase in capacity is enough to solve the challenge. However if more capacity is required, we can easily come up with increases of 50-100% in such projects.
