How To Collect Rainwater For Drinking A Step By Step Guide

Why Save Rainwater?

Rainwater is a great source of water. We get fresh water from the rainwater. Though sometimes we get this water with many minerals and salts. All are not useful. Some are also very harmful to our body.

Rainwater may be used as portable as well as non-portable uses like livestock watering, landscape irrigation, and washing.

Using and collecting rainwater has many benefits ranging from standard water quality to lessen stress on the underground aquifers.

Why Save Rainwater

Richard Heinichen said that all water is called rainwater. He is right in his opinion. All water from rivers, well, aquifer and harvested from rooftop previously were cloud-borne.

After falling from the sky, rainwater percolates by the rocks and earth, where it absorbs salts and minerals.

Heinchen indicates that for many cases, this water absorbs many contaminants like pesticides, industrial chemicals, and fecal coliform bacteria got in the earth.

Captured before

Reserve water before falling on the ground. View of the Texas Water Development Board is that there are no pollutants in rainwater which plagues underground and surface water supplies.

Rainwater contains low hardness level that lessens the application of detergents, soaps and removes the necessity of a water softener. Some materials resist tear and wear on plumbing fixtures.

Stored rainwater is a great source of water if power outages at the time of extreme drought when wells dry up.

There are some places where water supplies are very rear and not readily available. Collected rainwater is least expensive than storing bottle water.

Rainwater saving lessens the impact of aquifers, reduces the demand for threatened aquifers and ecologically sensitives.

Saving rainwater also minimizes flooding or erosion. About 50% of the land area is enveloped by the roof surface.

As it does not pump or treat and distribute by a complex network, reserving rainwater saves energy and the uses of rainwater.

Some municipal water users move to harvested rainwater to escape fluoridation and chlorination treatments.

Filters and Disinfection

The way of measuring filter is microns. 1 micron is about 1/25000 of an inch.

The measuring of sand is 100 to 1000 microns, the hair of human being is about 100 microns, the particle of dust is about one micron. A virus is smaller than .01 micron.

The first filtration system is cartridge filters. The range is more and capable of removing more.

Filters and Disinfection

Filters are nothing but the small size of particles that can capable of filtering. If the micron sizes are smaller, they are the better.

When it is finer, the slower the filtering process. Besides, it costs more. Filters need to change frequently as long time old filters are best for harmful pathogens and the microorganism.

For good water and rainwater system, a big filter is used to remove large particles and sand. The screens are easily accessible.

The after the filter is ten or twenty microns followed by ten to five-micron filter. They can clean least frequently but annually.

The task of the filter is to remove the substance from water. To ensure drinking water, filtration must be followed by disinfection.

The EPA needs ground or surface water to be disinfected before consuming.

Public water system adds disinfectants to remove microorganism which causes animals and people’s diseases.

It is an essential thing for rainwater also. But all are not harmful to us likely Giardia Lamblia may be deadly. Before consuming, you must need to remove it from the water.

There are various kinds of disinfections namely ionization, chlorination, membrane filtration, ultraviolet light. To evaluate disinfection, some unhealthy products must be treated.

The activeness of disinfection is measured by the indicator organism. It finds, implies that there is more pathogens present here.

The indicator organism is Total Coliform Bacteria denotes the presence of other pathogens in water.

Chlorine is used as a disinfectant for the public water system in various past countries.

The introduction of disinfecting water removes many diseases like typhoid, cholera, hepatitis, and dysentery. It also saves lots of lives. It may malign for possible side effects.

How To Collect Rainwater For Drinking

To disinfection, use 2.3 fluid ounces of household bleach per 1,000 gallons of water.

The amount of chlorine depends on the quality of water, temperature, and PH.

The negative side of chlorine is that it very easily combines with natural organic materials to make dangerous trihalomethanes such as chloroform.

Chloroform is created when chlorine acts as a fulvic acid or humic that are usually possible to get in the water.

Chlorine is dissipated and reactive. Keeping the dose correctly as applying the method of disinfection. THMs must be tested for water source as you like to use chlorine.

To remove harmful byproduct with using chlorine and make water purify, do the following things:

  • Eliminate the byproducts if it is created. The system is costly meaning that the process should be employed.
  • The attention of organics and particulates in the water prior to treating. You can do it by using the filters to remove particles from the water before chlorine treatment.

By using carbon filter you may change the taste and taste of water. It also called charcoal filter.

The filters are sometimes made of coconut shells and call a green solution. Carbon block filters are made of activated carbon mixed with the binding substance to a solid block.

Rainwater purification for drinking

There are many ways to treat rainwater to eliminate any contaminants which have the health risk. The professional advice and best way to get rid of this is to install a good type of water treatment system. The method treatments are stated below:

The aim of filtration is to remove particle or dissolve materials from water. There is lots of filtration system on the market. Particulate matter and microorganism vary according to the size and kinds of filters.

Water filters may not be a must to manage the chemical, microbial and physical quality of rainwater when tanks and catchments are well managed. Some filters need a power supply to operate it.

The purpose of using a filter is to remove some dissolved materials and particulate matter from water. There are lots of filtration devices found, and micro organism and particle removal vary for the type of filter.

UV disinfection by ultraviolet light irradiation (UV) is very active against protozoa, viruses, and bacteria. The UV system needs low maintenance, need no addition of chemicals and may add warning alarms to refer equipment faults. Specialist UV chambers are made to give a dosage of UV light at a given flow rate.

UV rays are very active when water is fresh and have no particles. Rainwater supplies require filters to confirm effective UV treatment. It fails to remove chemicals from water. The system needs a power supply. Water which may be disinfected using UV must be used straight away, not stored in tanks.

Chlorine disinfection is a very common form of disinfection which is very effective against viruses, harmful bacteria, Giardia. The good news is that has limited effect against Cryptosporidium. Notice the NSW Private Water Supply Guidelines page 35 for guidance on manually chlorinating a rainwater tank.
