DPW research becomes DPWE research
The dune water companies Dunea, PWN and Waternet have been doing collaborative research since 1998. In September 2014, Evides joins the group, and the 4 companies sign a declaration of intent to conduct research together over the next 3 years. KWR coordinates the DPWE research programme.
The 4 dune water companies produce drinking water through the infiltration of surface water in the dunes; a field which they research jointly with KWR. The name DPWE is made up of the initials of the 4 companies involved: Dunea, PWN, Waternet and Evides. The research programme focuses on subjects of great relevance for all 4 of the companies, ranging from the infiltration of pre-treated Rhine, Meuse and IJsselmeer lake water, to the ecological management of dunes (with the appropriate water quality and treatment), to the use of river and surface water and basins with corresponding water quality, large-scale transport pipelines, metropolitan areas, and to large, central water treatment.
Het Waterlaboratorium is one of the programme’s permanent partners: the lab advises and supports the DPWE members.
The companies see sustainability as a top priority and their approach encompasses the entire water cycle. An example is the research into the use of calcite in water softening. This DPWE research is conducted within the framework of the TKI Water Technology programme in conjunction with Reststoffenunie, WML and Brabant Water. The project studies whether ground and sieved lime pellets can be used as seeding material for water softening.
Collaborating with the energy sector
The DPWE programme also seeks to collaborate with non-water parties, such as those in the energy sector. In 2014, for example, GIS analysis is being carried out into the failures of gas and drinking water pipes. Water companies and gas network managers both use PVC and gray iron pipe material. The sharing of pipe failure information has revealed that while most failures in gas networks occur in gray iron pipes, in drinking water networks PVC pipes fail most often. GIS analyses show that failures occur primarily in areas with deep peat layers. To determine the influence of the location on the failures, the failure sites and the distribution net’s development have to be registered more precisely.
