Food gardens need water and what better way to give plants a drink than with soft, warm, oxygen-filled rainwater straight from the rain barrel. Even just a wee bit saved in a barrel after a storm, then transferred to a watering can, will slake the thirst of a balcony of plants. And you, the recycler, will feel especially good knowing that you are diverting water that would otherwise flow out into the storm sewers.
City Makes Rain Barrels Available to Save Water
City of Vancouver Rain Barrel
The City of Vancouver is providing subsidized rain barrels under a pilot program to conserve water.
The Rain Barrel pilot program will offer Vancouver residents (City of Vancouver only) a 75-gallon plastic rain barrel for $70. including taxes. Call 604-736-2250
For people outside Vancouver, the rain barrel is sold by Flexahopper Plastics, 604-946-8783, located at #12-7151 Honeyman, Delta, BC.
Residents can use the specially-designed barrels to collect rain water from downspouts for lawn and garden irrigation.
Lawn and garden watering make up almost 40 per cent of total household water use during the summer.
The barrels are easy to install. They come with outlets for both watering cans and hoses, and are designed with child-proof openings.
City of Vancouver residents can call the Compost Hotline at 604-736-2250 for information on obtaining a barrel. Residents can also visit City Farmer, at the City of Vancouver's Compost Demonstration Garden, at 2150 Maple Street to see the rain barrels in use.

Roll Out the Rain Barrels?
Rain barrel proponents claim that barrels conserve water, reduce urban runoff, and save money. But is it true?

Gardening Without Irrigation
See this excellent book by Steve Solomon, published complete, on-line. "So, to write Gardening Without Irrigation I grew two gardens side-by-side: a large "dry" garden and another large one intensive style, on raised beds with lots of irrigation. The "dry" garden was a place where I "grew with one hand tied behind my back" so to speak."
The Rainwater Harvesting CD
"The information has been collected from all over the world, from South and North, and from rural and urban areas. The emphasis is on domestic use of rainwater harvesting. The CTA Study Visit in Kenya shows many photos (additionally explained by voice) of different possibilities of rainwater harvesting used in Kenya." Posted November 23, 2002

Rainwater to Drinking Water
"The biggest issue in collecting rainwater is keeping it free of muck such as leaves, bird droppings and dead animals, and avoiding contamination with pollutants like heavy metals and dust." From the Sustainable House "In 1996, a Sydney family set out to renovate their 100 year old terrace house in the inner-city suburb of Chippendale. With a bit of vision, some common sense, and a lot of tenacity, they built what most of us would think impossible... a house in the middle of Australia's biggest city that produces its own power and water, and reuses its sewage on site."

The International Rainwater Catchment Systems Association (IRCSA)The IRCSA is a new association aiming to link those with an interest in the direct collection of rainwater and its storage for domestic and agricultural supply. The seeds for the establishment of the Association were first sown when the first International Rainwater Cistern Systems Conference was convened in Hawaii in June 1982 by Prof. Fok. Subsequent International Conferences have followed on a two-yearly basis and were held in the US Virgin Islands (1984), Thailand (1987), Philippines (1989), Taiwan (1991), Kenya (1993) and China (1995).
"Whilst rainwater catchment systems have long been utilised in some parts of the Caribbean, Middle East and Australia, in other places its potential has only recently been realised. During the last decade, Thailand and Kenya, for example, have led their respective continents in demonstrating the enormous potential of this technology. In Thailand more than 10 million two thousand litre ferrocement roof catchment tanks have been constructed since 1985 for domestic water supply, while in Kenya the construction of large (10 to lOOm3) ferrocement tanks has gained popularity in many regions with thousands being built at schools, clinics and private homes.
"Utilisation of rainwater catchment systems has also been spreading in other parts of Asia (e.g. Nepal, Bangladesh, India and the Philippines) as well as in Africa (e.g. Botswana, Mali and Tanzania). In industrialised countries too interest in rainwater collection is growing as demonstrated by recent developments in Australia, Hawaii and Singapore. Japan has traditionally used rainwater catchment systems and is currently making adjustments to meet the requirements of urban environments."

"It is estimated that 60% of the world population will concentrate into urban areas by the middle of the 21st century. ... Population in Asia, Africa and Latin America will continue to concentrate into large cities and, as a result, those cities will confront the problem "Urban Droughts and Urban Floods". ... A new rainwater culture is required in which cities can live more harmoniously with rain." (from the forward by Makoto Murase, Conference Secretary-General)

Tokyo International Rainwater Utilization Conference

The rain falling on the roof of the Sumida City Office, an 18-storey building completed in 1990, is collected in an underground 1000 m3 tank. The drainage from the bathrooms and restaurants in the building as well as the rainwater, is sterilized and used for flushing toilets.
According to data from 1993, the amount of water used for flushing toilets for that year was about 13,600m3. 7000m3 of that was rainwater, and recycled drainage accounted for 4000m3. This means that within the City Office alone, 11,000m3 of water were saved during that one year. This amount is equivalent to the amount of water needed to fill approximately 55,000 family bathtubs (200 liters).

"There are two categories of waste water: grey and black water. Grey water is all waste water from baths, showers and hand basins, domestic appliances and fittings. Black water is fouled water from toilets and bidets. The grey water that can be recycled is approximately 26% of the average consumption in a domestic dwelling (or 47% if the washing machine is included). The water used for toilet flushing is approximately 33% and outside use is approximately 3% of the average consumption. Grey water for toilet flushing can be supplemented by mains or rain water. The pay back time for grey water systems using waste water for toilet flushing is between 7 and 15 years depending on capital costs (£500-£1,000) and based on an average price of £1.28 per M3. The pay back time is reduced to 4-8 years in the South West where the price per M3 is £2.30. The payback time for grey water systems is shorter than rainwater systems but the manufacturers/installers need to consider the end users perception and attitude, health and safety aspects and legislation and planning permission."
"Envirosink is an environmentally helpful additional, or secondary sink that utilises all standard plumbing fittings. Envirosink allows you to conserve the 'light' gray water from your kitchen. Envirosink is the only system that allows some catchment of water at the kitchen sink -- to help fill your rain barrel in the dry season."
Bermuda"Here in Bermuda all residential properties catch rainwater on the roof. This is constructed of lapped limestone slate on a timber frame. The water collected drains down into a water tank which is located beneath the house. The general rule of thumb is that the tank must be large enough to hold, in gallons, an amount calculated by multiplying the roof area of the house by eight and a quarter. This water collection system has been in use for many, many years." (Department of Planning, Bermuda)

"Rainwater Collection Systems is the story of three families from the Texas Hill Country who collect rainwater for all their household needs, including drinking. And they would say 'especially' drinking!
'When emergency room physician Dr. Mike McElveen and his wife Kathy decided to collect enough rainwater for all their needs, their system became the model for others in their area to follow. A 50 page booklet accompanies each half-hour video.'

Rainwater Harvesting: An Alternative To The Roof Washer "When rain falls on a roof it usually starts gently and then increases in intensity. This rainfall will wash adhering pollutants such as soot and bird manure into the storage cistern causing faecal contamination. With leaf debris present, "ponding" of stagnant water in gutters can occur making matters worse. It is for this reason many authorities discourage or forbid the use of urban collected rainwater for human consumption. However, due to water shortages, rainwater collection for non-potable uses such as toilet flushing etc is beginning to be encouraged."
