Around the world people collect rainwater and use it as their main source of drinking water because they don’t have mains supplies. To do this they need watertanks so they can store it effectively. There are a number of potential issues with this though, including the fact that the resources aren’t filtered. This could result in health problems.
The problem with not filtering rainwater is that it can contain all kinds of unwanted contaminants. The most common things you can find in it include:
A wide array of different types of bacteria can be present in the water. While many of them aren’t harmful, there are others that can cause gastrointestinal problems, including E-coli. The bacteria can get into water because of animal faeces, insects, and deposits within tanks and pipes.
Traces of toxic metals
It is surprising how many different types of metal can end up in water. Many of them are harmful when ingested, including lead, nickel, and even arsenic. There are several ways these elements can get into the water, including as it runs down roofing materials and gutters into the tanks.
Managing the risk
The best thing to do to reduce the risk of exposure to these contaminants is to manage the water and tank properly. Keep in mind that the quality of the resources can also change quite quickly. You should:
•Check gutters, roofs and protective mesh every few months to make sure they are clean
•Have a look at the water quality regularly, specifically checking colour, taste, and smell
•Inspect the level of sediment in the tank every six months to a year
•Look at pumps and pipes to make sure they are clean
•Remove the sludge from the watertanks every couple of years
