Claim 13:
14. A method for treating wastewater arising from a plurality of oilfield well pads, comprising:
storing wastewater from a first man camp in a first septic tank at a first well pad spaced apart from a centralized treatment facility at least 0.5 miles;
monitoring, using a first sensor electrically coupled to a first transceiver and associated with the first septic tank, a condition of the wastewater stored in the first septic tank;
transmitting, by the first transceiver to a central transceiver associated with the centralized treatment facility, first data associated with the condition of the wastewater stored in the first septic tank;
storing wastewater from a second man camp in a second septic tank at a second well pad spaced apart from the centralized treatment facility at least 0.5 miles;
monitoring, using a second sensor electrically coupled to a first transceiver and associated with the second septic tank, a condition of the wastewater stored in the second septic tank;
transmitting, by the second transceiver to the central transceiver associated with the centralized treatment facility, second data associated with the condition of the wastewater stored in the second septic tank;
determining, at the centralized treatment facility and using the first data and the second data, a schedule for collecting at least a portion of the wastewater stored in each of the first septic tank and the second septic tank;
collecting, according to the schedule and using a wastewater transport vehicle, at least the portion of the wastewater stored in each of the first septic tank and the second septic tank and transporting the collected wastewater to the centralized treatment facility;
introducing the collected wastewater into a primary treatment system at the centralized treatment facility as influent, by directing the collected wastewater into a solid settlement tank and an equalization tank;
treating the influent with the primary treatment system, including the solid settlement tank and the equalization tank, to segregate settleable and floatable solids at the centralized treatment facility and thereafter balance a composition of the influent to produce primary effluent;
introducing the primary effluent into a secondary treatment system at the centralized treatment facility;
treating the primary effluent with the secondary treatment system to produce secondary effluent;
returning, using an effluent spray vehicle, at least a portion of the secondary effluent to one or more of the plurality of oilfield well pads; and
dispersing at least the portion of the secondary effluent on the ground at the one or more of the plurality of oilfield well pads.
