Some well known-problems in stations and networks can be solved without using advanced remote control and decision-making software. One good example of this is the built-in Delta start function in the ABS pump controller PC 441. For example, during heavy rainfall, several stations will fill up more or less simultaneously resulting in a high hydraulic loads and peaks in energy consumption and workload on the treatment plant.
By detecting a quick change in wastewater level we can decide to start and/or stop pumps before preset start/stop levels are reached! The total amount of sewage pumped will be the same (if not overflowing) but it will be spread out over a longer time period.
