In the northern part of the Delfland Water Board, eighteen pumping stations pump the wastewater from nearly 1.5 million people and 40,000 companies to two wastewater treatment plants, where it enters as an 'influent' via large discharge pipes. WWTP Houtrust in The Hague and WWTP Harnaschpolder in Midden-Delfland treat the wastewater to 'effluent', relatively clean water. All the wastewater treated at WWTP Harnaschpolder ends up in two effluent pipes via the effluent pumping station Harnaschpolder and flows over a distance of more than ten kilometers to the WWTP Houtrust. Together with the purified wastewater from this WWTP, the total effluent - a maximum total of 50,000 m3 per hour - is pumped through an effluent pipe of 2.5 kilometers in length before reaching the sea far from the coast. next step How the system works 1Where does all the water go? 2Pump stations 3Continuity and automation 4Basic data pumping stations More about the pipework 5Separated piping system 6Ring structure 7Transport pipes Key Figures Video (s) Photos & Illustrations Delfluent Services © 2018 - disclaimer Delfluent - Project Wastewater - PPP organization - Shareholders - Milestones Delfluent Services - Purify wastewater - Shareholder - Quality management - Calamities Innovations - Delft Blue Water - Sludge loading - Fermentation stage - Black Water - Purification Spui Downloads - Publications - Press Contact - Route - Addresses - Guided tours
