How to Store Rainwater for Drinking: A Comprehensive Guide

The Importance of Collecting Rainwater for Drinking

Water is an essential resource required by all humans to survive. Unfortunately, clean water isn’t readily available in many parts of the world. In regions where there is little or no access to a reliable municipal water supply, collecting and storing rainwater for drinking purposes can be a lifesaver.

Rainwater harvesting involves collecting, filtering, and storing rainwater from rooftops using gutters and downspouts. The collected water can be used for household chores such as watering plants or flushing toilets but also serves as an excellent source of potable drinking water when properly stored.

This article will take you through the steps involved in safely storing rainwater that can be consumed without harm.

Step 1: Collecting Rain Water

Collecting rainwater requires installing one or more catchment systems on your roof that consists of gutters and downspouts. These systems direct rainfall into storage containers such as tanks, barrels or cisterns installed underground.

When selecting catchment surfaces materials like zinc coated steel, aluminum, concrete tiles are preferable because they have fewer contaminants than other roofing materials like corrugated iron sheets. Therefore less debris flows from these surfaces into the collection container hence purer water quality.

Clean Your Catchment System Regularly

The cleanliness of the roofing surface affects how pure your harvested rainwater is hence regular cleaning is necessary. This includes removing debris like dirt leaves before it reaches your storage tank/cistern/barrel.

Although these solid particles do not pose health risks themselves; they contribute to bacterial growth which makes it hard to keep safe drinkable hydration.

Step 2: Filtering The Collected Water

As previously mentioned some elements may contaminate collected rainwater even if we use clean catchment materials proper maintenance does not guarantee total purity so filtration is crucial.

After rainwater has flowed from your gutters to your storage container, it would help if you filtered it before consumption. The filtration process involves removing any visible debris and particles that may have found their way into the water after its collection since filters can only remove impurities above a certain size; bacteria might still be present in the liquid.

Types of Filters

The two primary types of filters used in the filtration process are sediment filters and activated carbon filters. Sediment filter function by removing physical contaminants such as dirt, algae or sand.
On the other hand, an activated charcoal filter functions similarly except for additional absorption capabilities that undertake microbial removal and elimination of heavy metals.

Step 3: Treating Collected Water Using Chemicals

Chemical treatment is another step to take for potable drinking water collection. This step involves disinfecting collected rainwater with chemicals or purifiers like chlorine or iodine tablets before use.

It’s important to note that not all methods work equally well on all bacteria hence choose one that works best for you based on the bacterial analysis provided by a professional testing lab.

Final Thoughts

Collecting Rainwater can provide you safe drinkable hydration when done following proper guidelines. By installing catchment systems cleaning them regularly filtering collected water treating it using certified products will guarantee pure-potable-safe hydration anytime at no cost since this initiates environmental conservation efforts explicitly lowering demand on municipal resource allocations.A combination of these three steps will go a long way towards ensuring clean, pure, healthy drinking water for your family throughout the year.
