With the fast-increasing challenges of climate change and lack of recreational urban green spaces, we need solutions fit for a multitude of challenges. At Milford, we want to meet the growing demand for complete blue-green solutions that can help create the liveable cities of the future. At the same time, we also want to create multifunctional solutions that add greenery and create inviting city spaces where people want to spend time.
Against this backdrop, Milford has teamed up with innovative consultants in the Blue Green City Lab project. This collaboration pushed the product development and the process towards creating a complete blue-green solution. The collaboration paid off, as we are now launching Oasis™ (DK, SE) – the latest addition to innovative green-blue SUDS-systems.
The basic function of Oasis™ is to collect and harvest rainwater from urban roofs through the downpipe. The water is then fed into an aluminium box containing a rainwater chamber which can storage up to 540 L, as well as an integrated sediment trap. In addition to this, Oasis™ comes in two types of models – a raised planter and a bench – which work to add a green and recreative element to any space. Oasis™ is easily connected to other SUDS-solutions and is dimensioned to handle a typical 10-year rain event. There are great benefits to producing Oasis in aluminium - aluminium is more than three times as light as steel, it is an infinite source of reusable material, and it is very robust.
With regard to the product development process, Tanja Hasselmark Mason, who has been a consultant on the development project Blue-Green City Lab, explains:
“There is high demand amongst the private and public sectors to handle more water in a comprehensive solution that can cover various needs. We saw an opportunity in CoreBlue (DK, SE) to combine the technology of passive irrigation with planting, which can also handle more roof runoffs. As such, we created the groundwork for Oasis, which is now a product at Milford, and is a solution that can both collect and use rainwater as a resource.” - Tanja Hasselmark Mason, Scandinavian Green Roof Institute.
As part of the Blue-Green City Lab project and the ongoing collaboration with Scandinavian Green Roof Institute, Oasis™ is an active part of a series of tests. It is here that investigations, amongst other things, are carried out regarding the impact the passive irrigation system has on the root growth of the vegetation in the raised planter. This should reveal whether the CoreBlue solution reduces the need for manual watering throughout the season. The hope is that it will be able to extend the growth season.
Our urban landscape engineer, Aksel Jensen, explains the ongoing results that are being carried out by SLU Alnarp (The Swedish University of Agriculture) with Oasis™;
“We have two different varieties of Oasis planters with the same type of vegetation – one has three CoreBlue elements installed, while the other has a perforated drainage pipe. We then look at the added root growth of the vegetation throughout the growth season, while continuously measuring the moisture in the soil substrate. The soil substrate used in both plant boxes consists of a natural soil mixture from Bara Minerals - HEKLA® LÄTTJORD TYP C. The measurements will then be assessed when the season ends towards the turn of the year.” - Aksel Jensen, Milford.
Oasis™ helps reduce the challenges created by heavy rainfall, while adding more recreational and green qualities to the urban environment.
