Bacteria Removal

Harmful bacteria contaminants are one of the biggest issues of drinking water supplies in Ireland. Presence or non-presence of bacteria are the most important health indicators of drinking water quality. According to the EPA Report, there were 67 boil notices in place in 16 counties affecting 695,364 consumers in 2019. In many cases the boil water notices were issued because of bacteria in drinking water supplies such as Cryptosporidium, E. coli, Giardia, Coliform and inadequate disinfection during water treatment process.

If you would like to prevent this dangerous water bacteria from showing in your tap water or if a water test proves presence of water bacteria in your drinking water supply and you wish to protect your health then installing a water bacteria removal system will be the right choice for you.

Water Bacteria

The most common bacteria found in drinking water supplies in Ireland are E. coli, Enterococci, Cryptosporidium, Giardia, Coliform.

E. coli

Unlike many other disease-causing bacteria, E. coli can cause an infection even if you ingest only small amounts. Because of this, you can be sickened by E. coli from swallowing a mouthful of contaminated water…

Certain strains of E. coli bacteria can cause symptoms including diarrhea, stomach pain and cramps and low-grade fever. And some E. coli infections can be really dangerous. Young children and older adults have a greater risk of developing a life-threatening form of kidney failure.

Most common E.coli signs and symptoms are diarrhea, stomach cramping, pain or tenderness and nausea with vomiting. They usually develop three or four days after exposure to the bacteria.

Cryptosporidium (Crypto)

Cryptosporidium is a microscopic parasite that can cause watery diarrhea. Although there are more ways how to spread the parasite, water (drinking water and recreational water) is the most common way to spread cryptosporidium.

Apart from the most common symptom of crypto which is watery diarrhea, there are also other common symptoms such as dehydration, weight loss, stomach cramps or pain, fever, nausea and vomiting. The symptoms of cryptosporidiosis (illness caused by cryptosporidium) generally begin 2 to 10 days after infection. The symptoms usually last 1 to 2 week.


Enterococci are bacteria that indicate possible contamination of water by fecal waste. The bacteria can get into water from leaking septic systems, animal waste, effluent wastewater treatment plant or non-fecal sources such as plants, soil or sediment. The bacteria can also live in taps, so it is important to prevent contamination of plumbing and faucet heads.

Enterococci bacteria are not considered harmful for humans, but if found in water it may indicate that other disease-causing viruses, bacteria, and protozoa may be present. These pathogens can cause illness, diseases of the skin, eyes, ears and respiratory tract.

When enterococci are detected in a water supply, it is important to identify and eliminate sources of faecal matter and to implement proper disinfection systems. Immediate action is required to protect consumer health.


Giardia is a tiny parasite that is found in water that has been contaminated with feces from infected people or animals. Drinking contaminated water is the most common way how the bacteria spreads and makes people sick.

Infection by this bacteria causes stomach cramps, bloating, nausea and watery diarrhea. The infection usually disappears in a few weeks, but you may have intestinal problems long after that.


Coliform are bacteria that live in animal and human faces. Similar to Enterococci, this bacteria is an indicator of drinking water quality. The bacteria usually don’t cause illness, but the presence of Coliform in drinking water indicates that disease-causing organisms could be in the water system.


Water systems are one of the sources of Legionella bacteria. The bacteria become a health concern when they grow and multiply in a water systems such as showerheads and sink faucets, cooling towers, hot tubs, water fountains and water features, hot water tanks and heaters. People can get infected by breathing small droplets of water containing Legionella. The bacteria cause Legionnaires’ disease and Pontiac fever when get into lungs.

The symptoms of Legionnaires’ disease include: cough, shortness of breath, fever, muscle aches and headaches, diarrhea, nausea, and confusion. Symptoms of Pontiac fever are primarily fever and muscle aches.
