Stormwater Pumping Stations
According to IPCC and other experts, extreme weather events and very high levels of rainfall will be more frequent features of climate change. This increases the risk of flooding and the potential for subsequent damage. Depending on the local topography it may be necessary to protect residential areas from the effects of flooding by building stormwater retention tanks or by the provision of stormwater or combined sewer pumping systems to pump into the receiving water. This will ensure that predetermined high water levels are not exceeded. Otherwise there is the danger of back up and possible collapse of the sewer or channel system
As far back as 20 years ago, HST was providing polder stormwater holding tanks and stormwater pumping stations with smart control equipment. This type of construction and equipment has proven itself over the years and has been technically further developed and refined. In combination with accurate rainfall forecasts, the user has now the possibility to operate the stormwater protection plant in a reliable and secure manner. All the processes involved are controlled by the HST automation and process control technology.
ASK-Weirs are used to ensure maximum utilisation of the available stormwater retention capacity. By this means the operating times for the retention can be reduced. In addition, stormwater pump sizes can be reduced. Moveable 2-way flaps in conjunction with discharge tube mounted submersible pumps allow the construction of stormwater pumping stations on a smaller surface area. This means that sump structures for shut-off or diversion valves or dual relief lines are not necessary. The control and monitoring function is carried out by the process control system SCADA V10 in conjunction with rainfall data from NiRA.web. Maintenance and upkeep are organised by KANiO®.
