1. A water treatment method, comprising:
obtaining feedwater to be treated via a feedwater sourcing system;
treating the feedwater by conveying the feedwater through treatment system conduits incorporating a filtration system, a first pump system, and a reverse osmosis treatment system, wherein the filtration system is configured to produce permeate water, and wherein the reverse osmosis treatment system is configured to further purify the feedwater to produce reverse osmosis treated water;
further treating the reverse osmosis treated water via a post treatment stage to produce potable water; and
cleaning out the system conduits by flushing feedwater pursuant to a first flushing step through at least a portion of the conduits prior to purifying the water via the reverse osmosis treatment system, and further by conveying reverse osmosis treated water through at least a portion of the conduits,
wherein conveying the reverse osmosis treated water for cleaning out the system conduits comprises allowing the reverse osmosis treated water to displace the feedwater within at least a portion of the system conduits at a first pressure, and further by flushing the reverse osmosis treated water at a second pressure through at least a portion of the system conduits, wherein the second pressure is higher than the first pressure.
