Having access to clean water is crucial. When storms and emergencies happen, it is often overwhelming and many are unsure of what to do next. When you do experience flooding on your property, it is important to be aware of what category of water you are dealing with, so that you can avoid any possible contaminants in the water.

There are three categories of water. Category 1 water is clean water that is drinkable from the source. Category 2 water is grey water, which contains some contaminants and can cause illness if ingested. Category 3 water is water that is highly contaminated and should not be dealt with unless you are a qualified professional. 

Category 2 water refers to water that contains enough chemical, biological, or physical contaminants that the water will cause discomfort or sickness when you are exposed. These contaminants can include bacteria, viruses, and mold. Category 2 water can be classified when it is contaminated straight from the source, or as a result of category 1 water coming into contact with contaminated materials.

Potential sources of grey water include overflow from washing machines and dishwashers, water flushed from sink drains, stagnant water, and it can also include sump pump failures. 

To be safe around potential sources of Category 2 water, leave the contaminated area alone immediately. Contact professional help to assist you in drying the flooded areas and getting your property to be safe again. Be sure to tell SERVPRO technicians accurate and specific information about the flooding so that they can properly assess and mitigate the damage. Do not attempt to touch the water, or try to clean any of the water up yourself. 

Sources of Category 2 Water:


Washing machines overflow due to clogged drains or drain pipes that are too small in diameter to handle the volume of water needed.

Stagnant Water

Stagnant water is water that sits in place for days, weeks, or even longer. This is most common after a flood because water cannot drain properly in a flood. Standing water can soak into your home’s foundation and cause water damage. Seek professional help with stagnant water because it can be contaminated and structural damage could be present. SERVPRO can help you remove water and dry the affected areas after your home floods.

Sump Pump Failures

A sump pump’s job is to pump water out of a building so that the crawlspace or basement stays dry. When sump pumps fail, it can lead to flooding and standing water in these areas. Often this goes unnoticed in an unused basement, which can lead to stagnant water.  

These scenarios can quickly escalate into a category 3 water if not dealt with. Fortunately, SERVPRO of South Mecklenburg County can help you to deal with flooding in your home or business! Just call (704)-840-6112.
