High prediction accuracy
For one- to three-hour predictions of inflow volume, the error in the sum of root mean square is 7% or less, and over 95% of all prediction values is within 17% of maximum error.*
Prediction performance was reviewed and certified by the Japan Institute of Wastewater Engineering Technology, a professional examining authority.
*by in-house verification tests
Easy model maintenance
To ensure accuracy, it is necessary to periodically revise the prediction model according to changes in the population and modifications to the collection and treatment facilities.
The sewage inflow prediction system maintains accuracy of the prediction model by continuously gathering measurements necessary for model revision, such as actual inflow volume and rainfall data.
User-friendly equipment and operation
Using a PC and simple communication device, operators can access inflow volume predictions in real-time, 24 hours a day, 365 days a year. With Yamatake managing all aspects of inflow volume prediction and model revision, it enables operators to focus on the day-to-day management and operation of the treatment plant.
