While the use of captured rainwater is a tested and popular trend, the demand for other water reclamation techniques and products is growing, especially in drought-prone regions and among environmentally minded households.
One such trend in residential water reclamation is the use of grey water, which is the water from sinks, bathtubs, showers and laundry that would normally be sent directly to the sewage stream after use. Grey water, while not safe for consumption or first-use purposes, is practical for other household and gardening purposes, such as flushing toilets or irrigation of lawns and planting beds. The use of grey water can reduce overall household water consumption, saving consumers money and reducing the strain on municipal water supplies.
While whole-house grey water systems can be installed during construction, there are systems and products retailers can offer to retrofit existing plumbing, or to replace or retrofit current fixtures. Among these products are:
- Saniflo SANISWIFT Residential Gray Water Pump (www.saniflo.com)
- Aqua2use Greywater Recycling System (www.aqua2use.com). This is a whole house system with available filters and diverters that can recycle grey water into home reuse or irrigation.
- Caroma Smart 305 Round Front Plus, a sink/toilet combination unit. The sink drains into the tank of the toilet, which in turn uses the grey water for flushing. (www.caromausa.com)
- SinkPositive Touch-Free Water/Space-Saving Adjustable Toilet Tank Retrofit Sink/Faucet Basin. This replaces the standard tank lid with a sink unit that connects into the water intake line and drains into the toilet tank. (www.sinkpositive.com)
If customers are interested in grey water usage, retailers can also provide them with additional information and products. Be aware of state and local regulations for grey water usage. Also, once grey water systems are in use, only biodegradable and non-toxic detergents, soaps and cleansers should be used, especially if irrigation of plants is the final outcome.
Additionally, have your staff suggest a number of products that can help save water before use, such as low-flow faucets and showerheads, shower timers, dual-flush toilets, high-efficiency washing machines and water flow meters that can track areas of high water usage.
