On the trail of old pipes
The Municipality of Ringkøbing-Skjern and the water utility Ringkøbing-Skjern Forsyning liked the idea, and it was agreed that Ringkøbing-Skjern Forsyning would install a new rainwater pipe to Troldtekt’s plot. This means that a number of existing rainwater basins can be done away with as the water will now be led away from the plot, circumventing the wastewater treatment facility, to a new rainwater reservoir established by the utility.
The separation will not only cover the new area, but also existing buildings etc. However, it soon became clear that getting an overview of all the existing pipes and drains was no simple task.
“The factory has been added to several times over many years, so it was quite a big job mapping all the piping in the ground. Today, you are obliged to map and register all new pipes, but that wasn’t the case in the past. Considerable time and money has therefore been invested in preparing for the separation. This means that the registration is now fully under control, and the utility is saving a lot of resources for water treatment,” says Poul Erik Pedersen.
Less wastewater in watercourses
Ringkøbing-Skjern Forsyning is also pleased with the cooperation with Troldtekt, and the prospect of the wastewater treatment plant having to deal with less rainwater. It benefits the utility’s operating economy, and makes it easier for the utility to live up to the Environmental Protection Act (Miljøbeskyttelsesloven) and the Order concerning Waste Water Discharges (Spildevandsbekendtgørelsen).
“Separating the water cuts the costs of treating it, and also reduces the risk of overflows during cloudbursts. The wastewater contains organic matter and bacteria, and if it ends up in the natural environment, then oxygen consumption in streams and lakes will rise concurrently with a deterioration in water quality,” says Hans Schmidt, a project manager with Ringkøbing-Skjern Forsyning.
