The main water issues in the home are purification and conservation. Great strides have been made in both areas in recent years. One of the more interesting advances is permeable pavement, which is especially effective at helping filter chemicals that leak from cars parked in the driveway. Here are more examples.
- Drought-tolerant plants reduce the amount of time and money you'll spend on irrigation.
- Xeriscaping challenges the assumption that grass should always be the dominant design element of a yard and lets the climate determine what makes the most sense.
- Water-efficient appliances such as front-loading washing machines have attracted great consumer interest, and low-flow showerheads and toilets have been mandated by law.
- Water purification devices that use carbon to remove contaminants and reverse osmosis systems are effective in the home.
- Permeable pavement lets rainwater seep through, which reduces runoff and allows the soil underneath to act as a natural filter.
