How is water collected

Lower-pitched roofs tend to catch more water than steeply pitched roofs. Smoother roof textures will facilitate runoff better than textured roofs. Water rates: Areas with higher water rates will make rainwater harvesting projects more economically viable. Permits: Rainwater harvesting permits may be required.

Check with your local or state government. For more information, see the Rainwater Harvesting Regulations Map. System Sizing Here are the basic steps to properly sizing the storage tank of a rainwater harvesting system.

Determine how much rainwater is available for harvesting. FEMP's Rainwater Harvesting Tool can be used to estimate the amount of monthly rainfall over a typical year that can be collected from a rooftop or other hard surfaces.

If possible, determine the monthly demand for the application over a full year. Compare the amount of monthly rainfall that can be harvested to the monthly water demand over the year. Determine an optimal storage tank size that provides enough volume to store adequate rainfall to meet the demand while not oversizing the tank. Operation and Maintenance Rainwater harvesting systems require regular operation and maintenance. Inspect roof surface and ensure water flows and drains properly as intended.

Weekly 2 Inlet filter Screen filter to catch large debris. Clean out filter and replace at regular manufacturer-specified intervals. Weekly; manufacturer-specified intervals 3 First flush diverter Diverter that removes debris not captured by the inlet filter from the initial stream of rainwater. Monthly and after prolonged storms 4 Storage tank Storage tanks composed of FDA-approved, food-grade polyester resin material that is green in color, which helps to reduce bacterial growth.

Inspect tank for cracks or leakage. Annually 5 Overflow Drainage spout that allows for overflow if the storage tank gets full. Visually inspect overflow spout to ensure it is clear of debris. Monthly 6 Controls Control system that monitors water level and filtration system. Check that wiring is in good condition. Monthly 7 Treatment system Filtration and disinfection system that treats the water to non-potable or potable standards.

Clean and replace filters at manufacturer-specified intervals. Manufacturer-specified intervals 8 Pump Pumps move water through the system and to the end use. Check motor condition. All public water systems in the United States are required to follow the standards and regulations set by the U. EPA regulations that protect public water systems do not apply to privately owned wells or other individual water systems.

Owners of private wells are responsible for ensuring that their well water is safe from contaminants. Contaminants in our water can lead to health issues, including gastrointestinal illness, reproductive problems, and neurological disorders. Infants, young children, pregnant women, the elderly, and people with weakened immune systems may be at increased risk for becoming sick after drinking contaminated water.

For example, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Federal law requires that systems reduce certain contaminants to set levels in order to protect human health. EPA is responsible for making sure that public water supplies within the United States are safe. In and , the law was amended to protect drinking water and its sources, which include rivers, lakes, reservoirs, springs, and ground water wells.

There can be many sources of contamination of our water systems. The most common sources of contaminants include:. EPA regulates many contaminants that pose known human health risks. EPA makes sure that water meets certain standards, so you can be sure that high levels of contaminants are not in your water.

How do I filter water at my home if I am concerned about water quality? Different water filters have different functions.

Some can make your water taste better, while others can remove harmful chemicals or germs. How do I remove the parasite Cryptosporidium from my drinking water? The parasite Cryptosporidium can survive a long time, even after the water is treated with chlorine or iodine.

Ultraviolet light treatment of water is not effective against Cryptosporidium at normally used levels. How can I find out if there has been a violation in our public water standard? When water quality standards have not been met, your public water system must alert and notify customers if there is a risk to their health. Who do I need to contact to find out more information about water quality in my area? Every community water supplier must provide an annual report to its customers, known as a Consumer Confidence Report CCR.

How often does the local public water system test my drinking water? Create an account. Edit this Article. We use cookies to make wikiHow great. By using our site, you agree to our cookie policy.

There are many ways to collect water, and some are more accessible or sanitary than others. Consider the following places from which people often draw their water: Rainfall: You can collect and store rainwater. It is usually pure enough for drinking, cooking, and bathing.

Beware, however, of the chemical contaminants in "acid rain. National Institutes of Health Go to source Groundwater: You can collect water from underground using a tube well or a pump machine. This is usually pure water, although chemicals and bacteria can seep into the water table and contaminate this source. From a lake or pond: you can collect water from ponds, but this water is not usually potable.

It must be purified before drinking. You can, however, use it for watering or irrigation purposes. This is big source of all water of our daily use. Water from air: By applying new technology we can get collected water from air.

This may be a very small amount, but it could be useful in some circumstances. Understand grey water. Water collection can be done in a variety of ways, but the one thing in common that they all have is that the water in categorized as grey water. Grey water is water that has contaminants but may not be necessarily toxic, however it does need to be filtered and processed before it is classified as clean.

Apart from standard outside water use, grey water can also be used in cooling your house and filtration for more drinking water. Understand how government initiatives encourage rainwater collection. Reports on water management in various locations should be able to highlight most viable and economic ways to tap and harvest water for use. March , April PDF External. Private drinking water wells.
