Water is probably our most valuable resource. Yet, it is becoming increasingly scarce. Fresh water can be described as renewable resource, yet the world’s supply of clean, fresh water is gradually lessening. Even though we appear to possess an enormous water supply, all but three percent of the billion plus cubic kilometres of water on earth is salt water in the sea. 2.7% of the outstanding 3 percent happens to be permanently frozen in ice at the two poles. That will mean only a tiny fraction of the world’s water resources are available as fresh water. The obtainable water moves around in a permanent cycle through evaporation and rain fall. Presently there are concerns with the quality of drinking water as increasing water pollution brought about by nitrates, phosphates, pesticides and many other chemical substances is making purification very demanding and expensive. People’s need for water already is greater than availability in some areas of the world and as the earth’s population carries on growing, so also does the need for water. Understanding of the world wide value of safe guarding water for ecosystem services has only lately surfaced. This is because throughout the twentieth century, more than half the earth’s wetlands have already been lost along with their priceless environmental support systems. Freshwater ecosystems,with their distinctive biodiversity, are presently declining faster than marine or land ecosystems. Conserving water and making most beneficial use of it is today a consideration for people around the globe. Fortunately, we’ve all become more enthusiastic about rainwater harvesting and rainwater tanks.

Even before the Roman period, the concept of saving rainwater and saving it for later use is well documented and took place across the globe on all the main continents. In industrialise western countries, until recently, the principle of rainwater collection had mostly ceased because of the introduction of efficient mains-supplied water. With the ever-growing demand for water (and resultant spikes in cost), and the known adverse influences this might have on local environments, the call for rainwater recycling devices is on the rise. Throughout the world water conservation systems are being applied and developed to overcome water provision problems. There are specific water demand, supply and disposal concerns confronting water companies, developers and home owners as well that may present grave short and long-term challenges for the near future. Rainwater Harvesting can be utilised to help lessen these challenges. Surface water, i.e a large body of excess water to be disposed quickly, is already causing flooding of unprecedented levels, not before observed. A little-known fact is that for every ten percent of an area that is developed, surface water runoff grows by fifty percent. Consequently making provision to harvest and use significant volumes of water each day on innovative developments would make storm water useful rather than troublesome.. As yet in the uk this market is yet to be developed. In the interim, households could certainly do much to save water usage and can also collect and store rainwater on a restricted but having said that worthwhile scale.

It is believed that eight percent of global water usage is for household requirements. These requirements consist of drinking water, washing, cooking, sanitation, and for watering gardens.. Basic household water requirements have been determined at around 50 ltrs per person per day, excluding water for gardening purposes. Drinking water is water that is of sufficiently good quality so that it can be drank or used without the threat of immediate or longterm harm. This kind of water is generally described as potable water. In most developed countries, the water delivered to households, the business sector and industry is all of drinking water standard even if only a very modest quantity is in actual fact consumed or used in food preparation. Here are a few good ideas to enable you to save water: put a water displacement device into your toilet cistern (a brick or filled milk carton will do!) and when upgrading old toilets make certain the new model is water efficient. Don’t forget to mend dripping taps and lag external pipes to avert bursts and leaking. Stand under the showerin preference to a bath. Do not keep the tap running while you are brushing your teeth. When in the back garden try a watering can as an alternative to a garden hose also don’t be tempted to use a sprinkler. Water plants and flowers early in the morning or late at night to avoid water loss due to evaporation and in summer let turf grow longer since it stores moisture content far better in this way, don’t worry if it looks browning, your lawn will re-grow the moment favourable conditions return, as indeed is the case with most plants. Practice just a little benign neglect in the garden and don’t water too frequently, shrubs and perenials will put down deeper roots and be more robust plants if you allow them care for themselves. Use greywater (e.g. washing up water) to water non-edible plants. And buy a rainwater tank, big is beautiful here.

A butt of water will not go far during a dry spring when you’re attempting to establish plug plants and seedlings. Getting your hands on a larger rainwater tank is a smart plan if you have got the space. You should not forget when ordering rainwater tanks that you’ll need a diverter kit, hunt for types that feature these included in the price tag. Diverter kits will direct water to your tank, but as soon as the tank is completely full the water can be sent straight back down the drainpipe and into drains. Taps are another feature to be aware of,very handy certainly, but don’t forget to note the positioning of taps – do you have to bend down too far, can you stand a watering can below it? Filters are yet another nifty feature to look out for and can be fitted to gutters and drainpipes to stop debris like leaf mould from contaminating the water supply. Locate water butts and rainwater tanks in different areas of the garden. It is always practical if you can position them nearby to those spots that require the most watering, such as the vegetable patch. Of course large rainwater tanks should be situated by drainpipes that collect water from the largest roof surface area. You may find smaller butts are more suited for garden storage sheds and outbuildings. Happy harvesting and don’t forget every single drop is precious!
