The award-winning plant has been operational since 2019 and is situated in the heart of the city. It treats the wastewater from Utrecht and its surrounding villages. It has been designed to treat 65 million litres per day, which can increase to 30 million litres an hour during heavy rainwater conditions. It also removes twice as much nitrogen and phosphorus (TN 5.0 mg/l and TP 0.5 mg/l) as the original plant but is faster and up to 30% more energy efficient.
