The water quality in Dubai is one of the best, owing to the advanced treatment technologies implemented in the city. Dubai has the largest desalination plants in the UAE producing over 140 million imperial gallons of treated water per day. Although the water quality leaving the plant is good as per the drinking water standards, several factors cause some water quality issues in the distribution system and the storage tanks at households or apartment complexes. Proper care and maintenance will kill or prevent the survival of bacteria and viruses (pathogens) that can cause stomach sickness or more serious illnesses.
These measures also help prevent scale and slime (called biofilms) that can contaminate water and harbor pathogens. They also help control sediments and growth of algae that can also cause unpleasant taste and odors. Tanks should be sealed to help prevent contamination and screened to avoid mosquito breeding. The high temperatures prevalent in Dubai facilitate higher microbiological and algae growth. Therefore, it is imperative to get water storage tanks inspected and cleaned by professionals.
How does water storage tank disinfection take place? Here’s a breakdown.
The Water Storage Tank Disinfection Process
The Dubai Municipality recommends that water storage tanks should be cleaned regularly (preferably twice a year. Additionally, water well and storage tank disinfection should be performed under the following circumstances:
- A positive total coliform or E. Coli test
- After flooding or other well contamination, such as a cracked well cap
- After casing or pump repairs
- When drinking water taste or odor changes
- During new well or seasonal well startup
In case there is a contamination of the storage tank due to some unforeseen circumstances, customers should seek immediate professional assistance. Due to the special nature of the disinfection chemicals required, it is advisable to hire professional cleaning services for regular storage tank maintenance and cleaning.
Waterborne illnesses caused by bacteria found in contaminated household water tanks increase the risk of spreading waterborne diseases and may lead to many infectious outbreaks. Data from the World Health Organization (WHO) suggests that approximately 3.2% of deaths (1.8 million) and 4.2% of disability-adjusted-life years (61.9 million) worldwide are attributable to unsafe water, sanitation and hygiene. Water is the easiest mode of transmission for a variety of diseases such as cholera, typhoid, infectious hepatitis, amoebic, and bacterial dysentery. The contamination and transmission of such diseases can be prevented by maintaining proper sanitation, hygiene and implementing easy methods that will reduce or eliminate the presence of pathogenic microorganisms and filter the contaminated water to provide safe water for human usage and consumption.
