Increasingly frequent extreme weather phenomena, such as torrential rainfall, force the need to use retention and search for new technical solutions to minimize their negative effects, such as inundations or floods. One of the solutions are flow regulators that limit the flow rate from the catchment area and play an increasingly important role in water and wastewater management. Their main function is to ensure a constant value of the liquid outflow rate, as well as to stabilize the flows upstream and downstream of devices whose effectiveness depends on the volume of flow (wastewater pumping stations, pre-treatment devices). The answer to these needs is the “Flow regulator selection calculator”. The purpose of the tool is a quick and, at the same time, possibly precise selection of flow regulators for rainwater drainage systems.

After entering the appropriate data, the calculator automatically selects a device with appropriate parameters. Self-calculation allows you to save time and choose the most suitable device, e.g. the separator itself, or another pre-treatment system, e.g. a separator plus settling tank. The user can also download other documents – such as drawings or catalogs of individual devices. Using the form, the user can request a quote for the selected solution by contacting the manufacturer directly.

Retention reservoirs require regular removal of sedimenting impurities; this also applies to channels, especially those with a low slope, carrying water at too low a flow velocity. An economical and convenient solution is the use of automatic flushing systems in tanks and simple flushing devices in channels.
