Klaipeda wastewater treatment plant, serving Lithuania's third-largest city and main seaport, handles wastewater for 350,000 population equivalent. Located near the Baltic Sea adjacent to a UNESCO World Heritage Site, the facility was operating close to maximum capacity, with effluent quality approaching permit limits of 10 mg/l total nitrogen over recent years. This case study explores how the implementation of Hubgrade digital twin led to 180k€ savings per year thanks to operational costs cuts.
At Klaipedos Vanduo, the drive to optimize operations and cut costs was more than just a goal, it was a necessity.
Facing the dual challenge of keeping expenses in check while ensuring top-notch effluent quality, the team set their sights on smarter, more resilient wastewater treatment. Wet weather events, which often strain plant operations, became a particular focus. The ambition was to keep the Klaipeda WWTP running smoothly and efficiently, no matter the weather.
To make this vision a reality and minimize risks along the way, Klaipedos Vanduo searched for a partner willing to stand behind their solutions with a Performance Guarantee Contract. This ensured that the results would not just be targeted, but truly delivered.
In 2019, Klaipėdos Vanduo took a decisive step toward innovation by partnering with Hubgrade to bring real-time optimization to the Klaipėda WWTP. With this collaboration, the plant embraced Hubgrade Wastewater Plant Performance, a solution renowned for its digital expertise and ability to fine-tune operations across the wastewater treatment process.
By leveraging advanced digital tools and real-time data, Hubgrade empowered the Klaipėda team to make smarter, faster decisions, unlocking new levels of efficiency and performance for the plant.
The implementation of Hubgrade Performance delivered impressive results in operational efficiency and cost savings for the Lithuanian facility.
👉 180,000 € annual savings on energy and external carbon dosing
👉 1,180 tonnes of CO2-equivalent reduction per year
👉 Maintained compliant effluent despite increased BOD/TN loading
👉 Reduced environmental impact through lower total nitrogen in effluent
👉 Significant reduction in operational expenses for energy and chemical consumption
