Drinking Water Treatment

If your home water comes from a public water supply, it has been tested and meets EPA standards for drinking water. If you use a private well, however, you are responsible for assuring that the water is safe to drink. This means that you should periodically have your water tested, make sure your well is in proper condition without faulty well caps or seals, and identify and remove potential sources of contamination to your well such as leaking septic systems or surface contamination.

With a private well, you are also responsible for any treatment your water may need if it contains harmful pollutants or contaminants that affect the taste, odor, corrosiveness or hardness of the water. This fact sheet discusses different types of water treatment systems available to homeowners. Addressing the source of the problem is often less costly in the long run than installing and maintaining a water system. For more information on identifying pollutant sources, problems with your well, or help in testing your well water, see the references at the end of this fact sheet. There are many types of water treatment systems available. No one type of treatment can address every water quality problem, so make sure you purchase the type of equipment that can effectively treat your particular water quality issue. The table below can help direct you to the right solution for your problem.

Water can be contaminated by the following agents: 

■ Pathogens – disease-causing organisms that include bacteria, amoebas and viruses, as well as the eggs and larvae of parasitic worms. 

■ Harmful chemicals from human activities (industrial wastes, pesticides, fertilizers). 

■ Chemicals and minerals from the natural environment, such as arsenic, common salt and fluorides.

Some non-harmful contaminants may influence the taste, smell, colour or temperature of water, and make it unacceptable to the community. Water from surface sources is often contaminated by microbes, whereas groundwater is normally safer, but even groundwater can be contaminated by harmful chemicals from human activities or from the natural environment. Rainwater captured by a rooftop harvesting system or with small catchment dams is relatively safe, provided that the first water is allowed to flow to waste when the rainy season starts. The amount of water to be treated should also be assessed.

This can be estimated by assuming that each person will need a minimum of 20–50 litres of water a day for drinking, cooking, laundry and personal hygiene. A community should be consulted when choosing a water-treatment system and should be made aware of the costs associated with the technology. In particular, community members should be made aware of the behavioural and/or cultural changes needed to make the system effective over the long-term and thus be acceptable to them. Communities may also need to be educated about protecting water sources from animal or human contamination, and mobilized. It should be emphasized that all the positive effects of a water-treatment system could be jeopardized if the water is not drawn, stored and transported carefully and hygienically. The Fact Sheets in this section deal with both community and household methods for treating water.
