A pressurized sewage system (PSS) consists of a collecting tank, a pump and the pipes required to feed wastewater into the sewer main. With stricter environmental regulations calling for improved wastewater transportation, pressurized sewage systems have proven to be a safe, flexible and reliable way to move wastewater cost-effectively. “Nobody wants this kind of system any more.” “Environmental legislation no longer allows it”, says Alexander Vis, head of Xylem’s Pressure Sewage team in the Netherlands. Kinderdijk was one of the last areas in the Netherlands to use this system. If they filled up before that, the wastewater went directly into the surface water. The old sewage system comprised septic tanks that were emptied intermittently by a tanker. In 2008, the civil engineering consultancy ADCIM won a contract from the water board for the Rivierenland area (Waterschap Rivierenland) and the Kinderdijk World Heritage Association (Stichting Werelderfgoed Kinderdijk) to manage the project to connect the windmill site to the village’s main sewage system.ĭirk Burggraaf, project manager/advisor for water at ADCIM, says that Xylem was an obvious partner for this project, since the two companies have worked together before and it has “always worked really well.” Burggraaf said that the company was also a good choice because Xylem was already managing the micro pump stations in the adjacent municipality of Nieuw-Lekkerland. Though modern pumping stations have taken over the work of the windmills, the site has not been connected to Kinderdijk village’s main sewage system due to the technical difficulties involved. Its windmills, pumping stations, reservoirs and water channels were built centuries ago to protect the land, which lies below sea level, from flooding. ![]() ![]() Since UNESCO put Kinderdijk on the World Heritage List in 1997, it has become an important tourist attraction with between 175,000 and 225,000 visitors every year touring the site. Now a new Flygt pressure sewage system from Xylem has reduced its environmental impact and increased safety. For hundreds of years the site, including 18th-century windmills, dikes and old farmhouses, has protected the surrounding area from flooding. Edwin Bakker, director of the Centre for Terrorism and Counterterrorism at Leiden University, estimated that The Hague's Islamic State supporters consists of 200 men.Until recently, the World Heritage site of Kinderdijk in The Netherlands had an outdated sewage septic system that could potentially leak into surface water. A few young men hold up a black IS flag in the background.Īccording to the Dutch General Intelligence and Security Service, the Islamic State movement in the Netherlands amounts to a few hundred followers and several thousand sympathisers. In a YouTube video, he congratulated the Muslim community on the establishment of the caliphate in Iraq and Syria. He has been involved in demonstrations in recent years, and has been in contact with fighters in Syria. One of those detained is 32-year-old Azzedine Choukoud, known as Abou Moussa, a charismatic Dutchman of Moroccan descent. Mayor of The Hague, Jozias van Aartsen, said during a press conference that they had caught "big fish" who had "sown hatred and incited terrorism" on social media and news sites. The men detained come from The Hague, the city that positions itself as an international city of peace and justice, and which Islamic State sympathisers have also named "Jihad City". ![]() The Hague, Netherlands - Three Dutch citizens were arrested last week on suspicion of recruiting for the hard-line Islamic State (IS) group in its armed struggle in Syria and Iraq, as tensions between radical Muslims and Holland's far-right Pro Patria organisation continue to rise.
