Enhancing water efficiency can be accomplished in a few ways. First, it is possible to install water-efficient fixtures and appliances, such as low-flow toilets, faucets, and showerheads. It is just as important, though, to give regular maintenance and vigilant, fast attention to needed repairs to all pipes, both indoors and out—water has no path where it should not go, no matter the pressure, and every drop matters. Second, any number of alternate, or gray, water systems can repurpose plumbing to supply non-potable water for use in redundant, yet necessary, ways such as irrigation of plants great and small. Third, if fountain pens and refillable ballpoints can help conserve as much ink as possible, then personnel conservation is also a sure way of making a dent in reducing your system's water use.
