How Getting Rid Of Septic Tank Sludge Aids In Preventing Groundwater Contamination

Septic Tank Cleaning


In rural and urban areas throughout India, septic tanks are wastewater treatment systems constructed and located beneath the ground. Due to the absence of sewage treatment plants, all kinds of wastes from households, offices, institutions, and industries are collected in the septic tank.

Wastewater from the kitchen and bathroom containing food wastes, oil, grease, fat, human excreta reach the septic tank systems. A large number of households use an extensive amount of chemical cleaners which washes down the sink and reaches the septic tank.

In an ideal scenario, there are natural microorganisms present in the septic tank which breaks down the organic waste. Thus the solid waste settles down in the bottom and form septic tank sludge while the liquid waste floats on the top and flows out through drainage. The microbes prevent sludge build-up and help the natural function of the septic system. But it isn’t the case every time.

Due to the unhindered use of chemicals, the natural microbes are eliminated in the septic system and leads to sludge build-up and septic system failure. Drip by drip, the wastewater leaks and causes septic tank leakage and results in groundwater contamination which is detrimental to human health and the environment.


Groundwater System in India

WaterAid’s World Water Day report points out that India is the leading country in the world that uses groundwater which is 24% of the global total. It is also estimated that groundwater is the source for 85% of drinking water supplies. Unfortunately, it is susceptible to contamination due to harmful and toxic substances.

There are various potential sources of groundwater contamination such as storage tanks, hazardous waste, landfills, etc. In India, septic tank failures, and subsequent mixing of dangerous chemicals, toxic substances, and harmful microbes are found to be the major cause of groundwater contamination. This makes it unfit for human use.

When septic tank failure occurs, the wastewater spreads and seeps into the soil and finally reaches the groundwater which is below the water table. Those household and establishments which have septic tanks and groundwater source in close proximity are at greater risk. The consumption of contaminated groundwater can pose serious health risks. Of course, it depends on other factors like permeable soil, down-gradient, poor construction and maintenance of septic systems, etc.

Multiple water-borne diseases like hepatitis, diarrhea, cholera, typhoid, amoebiasis, and many other diseases are caused by harmful viruses, bacteria, and protozoa. Also, shallow groundwater is more prone to contamination in India.

An area with a high density of septic tank systems also increases the possibility of water contamination. Currently, septic tank overload or failure is treated mechanically which costs too much. This is the reason why common people disregard the dangers of septic tank leakage. Another reason is that many are unaware of the reasons like septic tanks behind the disease outbreak caused by ground contamination. Thus, it is important to act at the source which is septic tanks. This will prevent groundwater contamination.

One of the best ways to treat septic tanks is to use microbial solutions. Organica Biotech’s septic tank cleaning product range consists of Bioclean Septic and Bioclean Septic Plus. The powerful septic tank enzyme-producing bacteria completely degrades the organic waste and minimize the sludge build-up. The powerful solution thus prevents septic tank system failure. Plus, it curbs foul odor by inhibiting the growth of putrefying bacteria. One of the major highlights of Organica’s septic tank cleaning products is that they are natural, eco-friendly, and effective. This completely negates the need for mechanical maintenance of septic tanks, saves time and money, and prevents groundwater contamination as well.
