Abstract:
1. A system to control fluid flow in a wastewater treatment system, the wastewater treatment system comprising a wastewater treatment plant, a main connecting a plurality of pump stations to the wastewater treatment plant and carrying wastewater to the wastewater treatment plant, each of the plurality of pump stations located external to the wastewater treatment plant and including a wet well and a pump carried by the wet well, the system comprising: a central server; and a sensor carried by each of the wet wells and in communication with the central server to sense a level of wastewater within the respective wet well; wherein the pump in the respective wet well is automatically moved to an on position when the level of the wastewater in the respective wet well is at or above a first level; wherein the pump in the respective wet well is automatically moved to an off position when the level of the wastewater in the respective wet well is at or below a pump cutoff level; wherein the central server systematically manipulates the first level to selectively set the level of wastewater within the wet well; wherein a limited number of pumps are operated in the on position at a given time; wherein the central server prioritizes the limited number of pumps that are operated in the on position at the given time based on the level of wastewater in the wet well; and wherein the central server prioritizes the limited number of pumps that are operated in the on position at the given time based on a proximity of each pump to the wastewater treatment plant.
