Claim 8:
9. A system for treating wastewater arising from a plurality of oilfield well pads, comprising:
a first oilfield well pad at a first remote location, the first oilfield well pad having (i) a one or more wells, (ii) a man camp, (iii) one or more septic tanks each with a sensor disposed to measure a condition of at least one of the one or more septic tanks at the first oilfield well pad, and (iv) a transceiver electrically coupled to the sensor of each of the one or more septic tanks of the first oilfield well pad;
a second oilfield well pad at a second remote location, the second oilfield well pad having (i) one or more wells, (ii) a man camp, (iii) one or more septic tanks each with a sensor disposed to measure a condition of at least one of the one or more septic tanks at the second oilfield well pad, and (iv) a transceiver electrically coupled to the sensor of each of the one or more septic tanks of the second oilfield well pad;
a third oilfield well pad at a third remote location, the third oilfield well pad having (i) one or more wells, (ii) a man camp, (iii) one or more septic tanks with a sensor disposed to measure a condition of at least one of the one or more septic tanks at the third oilfield well pad, and (iv) a transceiver electrically coupled to the sensors of each of the one or more septic tanks of the third oilfield well pad; and
a centralized treatment facility at a central location determined based on the first remote location, the second remote location, and the third remote location and spaced apart from each of the oilfield well pads a distance of at least 0.5 miles and no more than 50 miles, the centralized treatment facility comprising:
a wastewater transport vehicle for collecting, according to a schedule and a navigational route associated with the schedule, wastewater from the one or more septic tanks of each of the plurality of oilfield well pads and transporting the collected wastewater to the centralized treatment facility;
a primary treatment system at the central location, the primary treatment system comprising a solid settlement tank and an equalization tank in fluid communication with the solid settlement tank, the primary treatment system being adapted to receive and treat wastewater from each of the one or more septic tanks from each of the oilfield well pads simultaneously;
a secondary treatment system at the central location and in fluid communication with the primary treatment system, the secondary treatment system having a membrane treatment system having a minimum daily throughput capacity of at least 10,000 gallons per day;
an effluent storage tank in fluid communication with the membrane treatment system;
an effluent spray vehicle in fluid communication with the effluent storage tank to collect a portion of effluent from the effluent storage tank and return the portion of effluent to any one or more of the plurality of oilfield well pads, the effluent spray vehicle having a plurality of nozzles for dispersal of effluent at the any one or more of the plurality of oilfield well pads; and
a central transceiver at the central location and in wireless communication with the transceivers of the first, second and third oilfield well pads to receive data associated with the condition of the one or more septic tanks of each of the plurality of oilfield well pads.
