Greywater Gets Real, Redux

Revisiting Riaan and Michelle of the South African reality TV series, Love and Mortar, I hoped the episode on their greywater reuse system would be available for posting given that the promos for each episode are available for viewing. But here is a video interview of them.

The only *news* I can find is that their new *green* dreamhome is built as shown in this photo and that they also had a baby during the course of construction.

Thanks for the memories, Riaan and Michelle.

Colors of Water

Clearwater many times thought to have come from a fresh water spring. Because water is composed of hydrogen and oxygen and both elements are invisible gases is a reason why water has crystal clear appearance. Tough to find these days in a natural state. Easy to find in a manufactured state and trapped in a bottle.

Whitewater, historical reference to noncorrupt activities by the Clintons pursued by a former special prosecutor. Sometimes also refers to water with lots of air or dissolved gas. Also connected to rapidly flowing water in rivers where lots of fun can be had in a multitude of floating devices. With incompetence in one arena, and competent treatment in the others, these waters remain harmless.

Greywater or graywater has many different definitions, I guess some could say “quasi conspiratorial” if one considers that graywater is neutral between whitewater and blackwater, but my previous job as a volunteer for the State of Oregon focused on HB 2080 which defines graywater as: “shower and bath waste water, bathroom sink waste water, kitchen sink waste water and laundry waste water. Graywater does not mean toilet or garbage wastes or waste water contaminated with soiled diapers.” No grey area in this definition.

Blackwater has many forms including a name formerly connected to a defense contractor who apparently liked the color of water in the Great Dismal Swamp of North Carolina. Also a Doobie Brothers. But in the water world, it is untreated wastewater from both urban domestic use and rural septic tanks. Blackwater also occurs in Australia as organic material, such as leaves and bark, that is washed into the river by a flood thus causing oxygen depletion. It can also be derived from dissolved manganese in groundwater and commonly stains porcelain fixtures. Peaceful means of treatment ultimately prevail against this colored water, but use extreme caution, some variants can be deadly.

Brownwater or the tea-colored water famous in swampy areas along the Mississippi River and Amazon River where rotting vegetation and humic and fulvic acids abound.

Greenwater is precipitation water infiltrated into the soil (so-called ‘‘green water’’) made famous by the grand dame of water mavens Malin Falkinmark of the Stockholm International Water Institute. Also greywater that has been disinfected for later use for irrigation becomes green.

Bluewater is water withdrawn and water consumed (withdrawal minus return flow to the river system) from rivers, lakes and aquifers for the purpose of irrigation. Also found as the water in nuclear power plants where spent rods are stored, but the subject of a different blog (wherever that might be).

Redwater is common when the water purveyor is tinkering with piping network, especially old piping networks, where sediment and rust are stirred up during servicing. Can also be a function of iron bacteria in water.

Purplewater is sometimes thought derived from Purple Rain popularized by the performer once known as Prince, but now referred to as recycled water from wastewater treatment plants conveyed in purple colored pipes for non-potable uses.

Yellowwater is a variant of yellow snow, derived from “where the huskies go" (homage to Frank Zappa).

Goldwater is the right drink for the conservative taste.
