Green: Rainwater collected from the roof by a graywater system
It has a $120,000 solar panel roof system, bamboo floors and a graywater system
for keeping the grass green.
It features a 35kW photovoltaic solar system on the roof that is designed to handle electrical needs and a commercial scale graywater system
to divert sink and shower water to irrigation purposes.
A graywater system
collects water from shower drains, bathtubs and the laundry, then filters and pumps it through a dedicated supply line to toilet tanks for flushing, reducing average household water consumption by one third.
This is the first graywater system
on campus, and in the near future I hope to also use the groundwater from Sewall Hall to irrigate the quad from Fondren [Library] to the Alice Pratt Brown music building," Miggins said.
Among the dozens of energy-efficient and "green" design elements built into the renovated house is a geothermal heating and cooling system consisting of a field of 232 bore holes 450 feet deep, and a three-acre constructed wetland and graywater system
that will reduce the sisters' water consumption by 40 percent.
I built a graywater system
that collects the water from the washing machine and kitchen sink in a sump basin in the basement (a sump basin is basically a plastic 55-gallon drum with a moveable lid).
In all instances, blackwater (wastewater generated by the toilet) must be disposed of through a separate treatment system, and the graywater system
must be plumbed so it can be diverted to the sewer system when necessary.
The Fat Spaniel display will also illustrate Queens Botanical Garden's pioneering energy efficiency and green building efforts within the visitor center, which include motion sensor activated lights, efficient ventilation, a waste-reducing graywater system
and a multifunctional green roof that merges architecture with landscape.
California's largest and fastest-growing PACE program, the HERO Program, finances a variety of indoor and outdoor water-saving measures, including whole-home graywater systems
and rain catchment systems.
Among his topics are water from springs, air conditioning condensate recovery, water gathered from clouds, solar water distillation, graywater systems
, aquatic plants as a waste management system, biological filter and constructed wetland systems, septic system design, and composting toilets.
Other ways to conserve water in the garden include drip irrigation, which releases just the amount of water plants need, and graywater systems
, which move used water from sinks and showers out into the yard for watering.
