Detecting and Reducing Extraneous Water in Sewer Networks

Extraneous Water Sealing System for street manholes (inspection shafts) protects against surface water entering through the ventilation openings of the manhole cover.The Extraneous Water Sealing System is proven to be effective especially with these advantages: It has an aeration and deaeration function, is low-maintenance and convenient due to automatic closing and opening. All materials used are suitable for permanent use in sewer systems.Application areas of the Extraneous Water Sealing SystemSuitable for manhole openings with a diameter of 625 mm +- 5 mmApplicable for overflow heights up to 0.5 m above street levelDesigned for manholes according to DIN 4034 and manhole covers according to DIN 19584 (standard BeGu frame), special mounting supports available on requestAdvantages of the Extraneous Water Sealing SystemReliable sealing of manholes in case of surface water inflowFull aeration according to DIN EN 124 after surface water inflow ceases Low maintenance due to large sediment collection space Suitable for overflow heights up to 0.5 m Special dimensions available on request Prevention of biogenic corrosion in sewer systems with aeration and deaeration function

With the UNITECHNICS UniVario System DN625 you reliably prevent odour nuisance from sewer shafts while at the same time providing secure protection against inflowing extraneous water. The complete system combines a powerful inflow water seal with a highly effective odour control module – for maximum operational safety, optimal shaft ventilation and significantly improved air quality in the surrounding area. Innovative, low-maintenance 2-in-1 design The UniVario System DN625 combines the proven functions of the predecessor models Uni-FreWa (extraneous water protection) and Uni-AdSorber (odour control) in one modular complete system. The integrated extraneous water seal closes automatically when surface water flows in and reopens on its own once the water has drained, ensuring full ventilation in accordance with DIN EN 124. The enlarged adsorber filter volume provides effective, long-lasting neutralisation of sewer odours without any need to replace the filter. Simple installation and maximum workplace safety Installation is tool-free and requires no entry into the shaft. The adsorber and extraneous water protection unit remains easily accessible from the surface, eliminating the need to open the manhole cover unnecessarily and avoiding hazardous shaft entries. This increases workplace safety while reducing the effort required for inspection and maintenance. High-quality materials for durability The UniVario System was designed for permanent use in the sewer. The robust, corrosion-resistant construction ensures a long service life, low operating costs and reliable functionality even under demanding conditions. The integrated sediment chamber also allows for quick and easy cleaning when maintenance is required. Tailor-made solutions for special requirements For special applications – e.g. industrial shafts or aggressive media – special sizes and custom versions are available. We are happy to advise you on individual requirements or non-standard installation situations.

With the UNITECHNICS UniVario Air DN625 you effectively prevent sewer odours and permanently improve air quality around inspection shafts. As a powerful adsorber attachment, the system uses a self-regenerating special filter material that reliably binds sewer gases without ever needing a filter change. Innovative, low-maintenance odour control system The UniVario Air DN625 is the successor to the proven Uni-AdSorber and was specifically developed for long-lasting odour neutralisation. Thanks to the enlarged adsorber volume and the innovative filter material, unpleasant odours such as H₂S are reliably bound – without any biofilter or activated carbon. The filter material regenerates itself through incoming rainwater, enabling low-maintenance use over long periods of time. Simple installation and maximum workplace safety Installation is entirely tool-free and requires no entry into the shaft. The adsorber is simply mounted onto the UniVario Base DN625 and remains easily accessible from above. This avoids unnecessarily opening heavy manhole covers and significantly increases workplace safety. Thanks to tool-free installation, the UniVario Air can be retrofitted or replaced at any time without anyone having to enter the shaft. High-quality materials for durability The UniVario Air DN625 was designed for permanent use in wastewater facilities. The robust, corrosion-resistant construction ensures a long service life, low operating costs and reliable performance, even under demanding conditions. The system remains permeable to surface water and continues to allow stable shaft ventilation while effectively retaining odours. Tailor-made solutions for special requirements For special applications – e.g. shafts with aggressive wastewater or high H₂S loads – special sizes and custom versions are available. We are happy to provide individual advice on unusual installation situations or increased loads.

The UNITECHNICS UniVario Base DN625 reliably protects sewer shafts against inflowing surface and extraneous water that can enter the shaft through ventilation openings. As the base module of the UniVario system, the extraneous water seal impresses with its robust construction, high operational safety and significantly improved shaft ventilation. Innovative extraneous water protection system for lasting safety The UniVario Base DN625 is the further development of the long-proven Uni-FreWa. The system closes automatically in the event of heavy surface water, preventing extraneous water from entering the shaft – and reopens on its own once the water has drained. This ensures full ventilation in accordance with DIN EN 124 at all times. The optimised shape supports improved airflow in the sewer and thereby helps reduce odour formation. Simple installation and improved workplace safety The extraneous water seal can be installed entirely without entering the shaft. Thanks to its simple handling, there is no need to unnecessarily open heavy manhole covers, which significantly increases workplace safety. The design allows for quick installation and removal – ideal for regular visual inspections and maintenance work. High-quality materials for long-lasting use The UniVario Base DN625 was specifically developed for permanent operation in the wastewater network. The robust, corrosion-resistant design ensures high stability and a long service life – even under demanding conditions. An integrated sediment chamber collects any particles that are washed in and can easily be cleaned via the inspection opening.
