Rainwater Tanks

Water is definitely the world's most valuable resource. However, it is becoming increasingly scarce. Fresh water is a renewable resource, yet the world's supply of unpolluted, fresh water is progressively decreasing. Despite the fact that we seem to have an enormous water supply, ninety-seven percent of the 1.4 billion cubic kilometres of water in the world is ocean. 2.7% of the last 3% is in fact permanently frozen in ice at the North and South poles. That would mean only a tiny fraction of the planet's water resources are useful as fresh water. This valuable obtainable water moves in a permanent cycle by way of evaporation and rain fall. Presently there are problems with the quality of drinking water as growing water pollution caused by nitrates, phosphates, pesticides and various toxic chemicals is making purification progressively difficult and expensive. Our need for water already is greater than supply in several regions of the world and as the world population continues to rise, so also does the need for water. Understanding of the international importance of saving water for ecosystem services has only just lately emerged. This is because in the course of the twentieth century, in excess of fifty percent of the planet's wetlands have already been depleted coupled with their invaluable environmental support systems. Freshwater ecosystems,with their distinctive biodiversity, are currently declining more rapidly than marine or land ecosystems. Saving water and making most beneficial use of it is these days a top priority for people around the earth. The good news is, we have all become more focused on rainwater harvesting and rainwater tanks.



Even prior to the Roman era, the process of capturing rainwater and saving it for use later is well documented and occurred around the globe on all the major land masses. In industrialized countries, right up until fairly recently, the practice of rainwater collection had basically died away with the introduction of dependable water from the mains.. With the increasing demand for water (and consequent increases in price), and the known unfavorable effects this may have on localized environments, the call for rainwater recycling systems is on the increase. Around the world water conservation systems are being utilised and made to forestall water supply difficulties. There are specific water demand, supply and disposal concerns confronting water companies, developers and homeowners together that might present grave short and long-term challenges for the future. Rainwater Harvesting can be employed to help manage these challenges. Surface water, or a large body of unwanted water to be drained away swiftly, is at present contributing to flooding of unparalleled levels, not previously observed. A little known fact is that for every 10% of an area that is developed, surface water runoff increases by fifty percent. As a result making provision to collect and use significant volumes of water each day on new developments would make storm water beneficial instead of problematic.. As yet in the United Kingdom this field is yet to be developed. In the interim, individual households are able to do much to conserve water consumption and might also collect rainwater on a modest but nevertheless worthwhile scale.



It is thought that eight percent of worldwide water use is for household requirements. Most of these requirements consist of drinking water, bathing, food preparation, sanitation, and for watering gardens.. Standard household water requirements have been determined at around 50 litres per person per day, excluding water for gardens. Drinking water is water that is of sufficiently good quality so that it can be drank or used without the threat of immediate or lasting harm. This kind of water is widely termed potable water. In virtually all developed countries, the water supplied to households, commerce and industry is all of drinking water quality although only a very small percentage is in fact consumed or used in cooking. Listed here are a few pointers to make it easier to conserve water: fit a water displacement gizmo into your toilet cistern (a brick or filled milk carton will do!) and when replacing old toilets be sure the new toilet is flush efficient. Be sure to fix dripping taps and lag exterior pipes to avoid bursts and leaks. Stand under the showerin preference to a bath. Do not leave the tap running if you are cleaning your teeth. In the garden start using a watering can instead of a hose pipe and don't be tempted to use a sprinkler. Water plants and flowers first thing in the morning or later at night to prevent water loss by means of evaporation and in summer time let your lawns grow longer because it stores moisture content better this way, don't be anxious if it appears brown, your lawn will rejuvenate when favourable growing conditions return, as indeed is the case with most plants. Practice just a little benign neglect in the garden and do not water too much, shrubs and perenials will put down deeper roots and be healthier plants if you make them fend for themselves. Use greywater (e.g. dish water) to water inedible plants. And get hold of a rainwater tank, the bigger the better!



A barrel of water does not go far during a rainless spring when you are hoping to establish seedlings. Buying a much larger rainwater tank is a good choice if you have got the space. Do not forget when choosing rainwater tanks that you might need a diverter kit, find models that feature these integrated in the total price. Diverter kits will redirect water to your rainwater tank, but when the tank is full the water can be redirected back down the drainpipe and into drains. Taps are an extra function to consider,very useful certainly, but don't forget to take note of the placement of taps - do you have to bend down too far, can you stand a watering can below it? Filters are another neat feature to look out for and can be fitted to gutters and drainpipes to prevent debris like leaf mould from contaminating the water supply. Position water butts and rainwater tanks in several areas of the garden. It is always beneficial if you can locate them nearest to those spots that require the most watering, such as your veggie patch. Naturally larger rainwater tanks should be put by drainpipes that collect water from the largest roof surface area. You may find smaller butts are more suited for garden sheds and outbuildings. Happy harvesting and don't forget each and every drop counts!  Maybe a helpful garden gnome will count the drops for you!
