The Revolution

This is a revolution. If you want to shut an airport then stop flying. Want an end to factory farming? Grow your own. An end to pollution? Change to renewables. An end to war & poverty? Microgenerate. Life for your childen? Stop needing oil. YOU have THIS Power. You do not need Government. Seize the initiative. Bring democracy to your community. Be an example to your children. Take responsibility. Change for good today.

Water the Tree of Life

     What on Earth is going on here? Aren't we saving Carbon or something? Well, yes, but as explained, almost everything we do in a modern Northern/Western economy is driven by Oil. Hence so are the utilities to our homes. This includes the collection, cleaning and pumping of our drinking water. A luxury that most of the World's population have yet to enjoy. Sadly very few of them ever will.

     There is no need to centralise our water supplies around reservoirs & 'water works' like there is no longer any need to centralise our electricity supplies around large power stations. This is because water, like Solar Power is essentially decentralised. It is free, it literally falls out of the sky like rays of sunshine. So why do we waste so much energy cleaning it and pumping it? Well, there is lot of legacy pipe work buried in the ground. The other reason is the economies of scale - sometimes big is better. Read on....

Our Coming New Reality

     Just as Globalisation will be replaced by Localisation then big will tend to small. Our information and media services will tend to the distributed power of a billion nodes on the Internet that no one body can organise or control. Our Electricity Power Stations will simply be switched off when nobody uses them any more, ie, when everybody takes their power from small local Wind Farms, Combined Heat Power units or Photovoltaics. Just as this is true it will slowly become so that the need to pump water to our homes through high-maintenance legacy distribution hardware will become a thing of the past.

     Water literally falls from the sky. It rains, it is free but we just let it wash away down our drains. We waste it like we waste the thermal energy in the ground and the sunlight that falls upon our heads. If we can capture the sun energy as warmth and electricity why can't we capture the rain? And so we can. The average house is quite able to capture, store and clean a large proportion of the rain that falls upon it. More than that - we can easily capture most of our waste water and recycle it for its heat and its normal water-usage - such as watering the garden.

     Some of the measures we can take are quite cheap and simple. Practically any house in the industrialised/developed world with guttering around the roof can capture water from the downpipes and divert them into one (or more) water butts (barrels) for usage later. Rain water is great. If you live in a hard water area and have despaired of ever getting your car clean without white streaks and blobs then do not worry. Sell your car! Well, if you can't do that yet then at least rinse it down with a couple of buckets of rain water from the water butts. Heh presto - no streaks!

     Of course we recommend you mainly use it for watering the Garden in summer. If you live in countries often struck by drought in summer then you may find yourself forbidden by law from using a hose-pipe to water you garden. In fact you really shouldn't use drinking water to pour onto your land at all. It is a terrible waste in a world where thousands die for want of a sip of disease-free water. Worse still please don't water your lawn - better your vegetable patch. If Climate Change really does happen then our weather could become very strange. We could yet experience appalling droughts and sweltering temperatures. The idea of pouring clean drinking water down the drain will be as bad as using a tungsten filament light bulb.

     So what are the alternatives? There are a range of technologies now available under the title of "rain harvesting". They come as three major types. On capture rain water in large tanks and cleanses it to make it potable. Others will take just the rain water and connect it to your mains supply to flush toilets of be used with washing machines. The third type of system is a slightly more sophisticated version of our simple water butt example. This uses very large water tanks buried in the garden and a water pump to allow you to suck the water out and spray it over your vegetable patch.

     Whatever technology you choose it will improve your survivability and independence in an uncertain future.

Natural ways to clean Sewage

     Effluent from a septic tank can be fed through layers of sand and gravel planted with reeds. The reeds help bacteria to break down pollutants and makes the reed beds attractive to wildlife. However, such a "do-it-yourself" solution to sewage in unlikely to be either practical or attractive to most UK householders. One for the off-grid enthusiast only.

Milla Waters the Garden with Recycled Rain Water     This one is a bit different. I don't understand why we need Oil to give us water. The Water keeps falling out of the sky and onto my face. Mummy wraps me up or rushes me inside. All this free water!! So Daddy said "Let's catch the rain and re-use it". So that is what we do now with two large water barrels that store water from the roof. Daddy waters the garden from them.

Grey Water & CAT Advice

     "Grey" Water is the dirty/soapy water resulting from baths, showers, washing machines, washing up, etc. It cannot be stored for long otherwise it starts to smell. This can be kept for a short spell and used to water the Garden. Simple kits are available to allow the outflow from a bath to be redirected to a storage tank for later use. The detergents used in washing machines can be harmful to plants so, instead, use a low-sodium detergent.

     Such water can be treated using disinfectants but these took a lot of energy to make in the first place and cannot be recommended. Running costs of such systems can be higher than utility-supplied tap water. There is no net environmental benefit. Unless you are off grid or in a very dry country then there is little to recommend such systems.

 

 

 

Rain Harvesting & CAT Advice

     You can spend a lot of money on a system that will collect your rain water and separate the debris from the clean water. This water can then be pumped into a tank in your roof to be used to flush the lavatory. However CAT do not advise that this is necessarily beneficial due to the energy requirements of the electronic controls and pump.

     Likewise taking rainwater and treating it to make it drinkable is not recommended by CAT. Generally they advise a composting toilet as a better way of reducing water usage. Treating your own water should only really be required if you are off grid or if you live in a very dry country. All-in-all CAT recommend reducing your water wastage and the simple water butt idea for watering your garden.

 

 

 

The Final Word

     Whilst Chris Goodall has much to say about the carbon footprint of heating water up with fossil fuels there is very little in "How to Live a Low Carbon Life" about the actual footprint of cold water itself as delivered to a house in the UK. However if your turn to page 140 of the original imprint released in 2007 (softback) then there is talk about the savings from using less water in newer washing machines. He says the direct savings from switching from an old washing machine to a modern one are 50 litres per wash. Over a year the indirect savings are estimated at 12kg Carbon.
