1. A water filtration system comprising:
a coarse filter configured to filter sand/sediment from water fed to the coarse filter;
a fine filter configured to filter water passing through the coarse filter, wherein the fine filter is configured to filter out foreign material larger than a selected filter pore size;
a fluid pump configured to pump water when a DC voltage is selectively applied to the fluid pump, wherein the fluid pump is positioned in-line with respect to the coarse filter and the fine filter such that the fluid pump either draws or pushes water into the coarse filter or draws or pushes water into the fine filter;
an inlet connector directly coupled to the coarse filter and configured to allow water to enter the coarse filter;
an outlet connector configured to output filtered water received from the fine filter to one or more sinks, showers, and toilets;
a grey water tank configured to receive and store grey water, wherein the grey water tank and at least one of the one or more sinks and showers is coupled via a grey water line;
an ozone module configured to produce ozone for treating the grey water in the grey water tank to produce treated grey water;
a water controller configured to selectively couple the treated grey water from the grey water tank to the coarse filter via the inlet connector; and
a power source communicatively coupled to the fluid pump and configured to output the DC voltage applied to the fluid pump.
