Swimming pools in the US:
Swimming pools are seen by many as a status symbol. Since the 1950′s, swimming pools have been increasingly popular in the United States.
1950′s: 2,500 residential pools in the US
2010′s: 300,000 public pools in the US
10,000,000 residential pools in the US
Phoenix area: 300,000 swimming pools – 20,000 new ones are built each year. There are currently around 10,000 unused pools in foreclosed homes in the Phoenix area that are empty or need to be sprayed with chemicals to prevent the spread of the West Nile virus in green pools.
A pool in the desert has to be virtually refilled every year, increasing the waste of potable water used by a family an average of 10%. An 18 feet x 36 feet pool can lose around 7,000 gallons/year.
Pool filter pumps can be the second-biggest electricity user in a home, next to air-conditioners.
Pools rely on chemicals to stay algae-free. (chlorine + muriatic acid = mustard gas = illegal in warfare b/c Geneva Convention – known carcinogen and mutagen)
The Garden Pool:
Our Garden Pool easily feeds our family of four with about 8 eggs a day, unlimited tilapia fish, fruits, veggies, & herbs.
Dimensions: 16′ W x 30′ L = 480 sft in size = small studio apartment size. The main structure only took 2 days to build.
The pool was originally about 3′ – 9′ deep and is now 15′ max height with the greenhouse top.
Materials: Spent about $1500.00 – Treated 2×6′s & 2×4′s, 1/2″ braided steel cable, 20′x40′ 12mil clear UV treated tarp, 3000 cfm evap cooler, 90 Watts Solar, Power Inverter, Marine Battery, 5 gallon buckets, storage totes, scrap wood, redwood lattice, lava rock, drip irrigation tubing, rain gutter, hydroton, air stones, 2 air pumps, 2 pond pumps, etc.
When we were growing in containers with soil, we watered almost exclusively with recycled greywater. 30% of residential water used is greywater. Top-loading machines use up to 80 gallons per load. Front loading use about half that amount. Bathing consumes around 60 gallons of water per person.
We are currently developing a marsh-like system to purify our greywater to help keep the GP full of water due to water loss from evaporation.
