Water that is salty or has arsenic might still be good enough for washing and sanitary purposes. Tanks are often perceived to have environmental costs that are comparatively lower than other water supply augmentation options. Many places in Latin America have rainfalls of about 500 millimeters per year.

In these cases, rainwater harvesting can be an effective and low-cost solution. While rain water is pure it may become contaminated during collection or by collection of particulate matter in the air as it falls. Here is the main page in Wikiversity:. In developed countries, rainwater is often harvested to be used as a supplemental source of water rather than a main source, but the harvesting of rainwater can also decrease a household's water costs or overall usage levels. The cycle contains surface water, groundwater and rainwater.
How can we improve on this? This article has been rated as C-Class on the project's. This practice has been around for thousands of years and has been growing at a rapid pace. Rainwater is generally considered fit to drink if it smells, tastes and looks fine; However some pathogens, chemical contamination and sub-micrometre suspended metal may produce neither smell nor taste and may not be visible. It can be used for cleaner,washing clothes etc. For example, in new houses which have rainwater tank connected to all flush toilets are given an additional 1-star of the required 5-star.

They can become as breeding grounds for many animals if they are not properly maintained.
This is almost inevitably the case for many. We sourced these from the Rainwater Harvesting Community - a sub community within the Rural Water Supply Network community on Dgroups - which is a free member-only forum, where people can ask a pool of over 700 members from 86 countries about rainwater harvesting. Industrial systems Rainwater may also be used for groundwater recharge, where the runoff on the ground is collected and allowed to be absorbed, adding to the groundwater. Sachetana seeks to provide rooftop rainwater as fluoride free water to drink. While Roman Aqueducts are well-known, were also commonly used and their construction expanded with the Empire. In addition, rainwater harvesting decreases the demand for water from wells, enabling groundwater levels to be further sustained rather than depleted.

Each 20 litre container of clean water might save a kilometers long walk to the nearest source of clean water, and as fetching water on cold, wet and slippery days is particularly unpleasant, even this small yield is highly valued.
One of the simplest ways of storing water from the collection is storage tanks. Later, as Venice acquired territories on the mainland, it started to import water by boat from local rivers, but the wells remained in use, and were especially important in time of war when access to the mainland water could be blocked by an enemy. While rain water is pure it may become contaminated during collection or by collection of particulate matter in the air as it falls. Since both articles contain unique and complementary information I support merging the articles or building a stronger link between the two. It also helps in the availability of potable water, as rainwater is substantially free of salinity and other salts. Many countries, especially those with arid environments, use rainwater harvesting as a cheap and reliable source of clean water.
