Water waste treatment needs to get priority


Do you know that more than 70% of the Earth is water? But with 97.5% being salt water and 2.5% being freshwater and out of that too only a lesser percentage is fit for human use.

United Nations latest report says that severe droughts will impact 2-5% of India’s GDP

Amid the raging COVID19 pandemic, wastewater management needs top priority since washing hands from time to time has become the need of the hour. So each human is using three times more water in the day than the average use we did before 2019. Moreover rising levels of population, increasing urbanisation, and fast moving industrialisation has led to an overburdening of the wastewater problem in India. Our water sources have been depleting rapidly. Thus, we have no option but to move towards water conservation and the first step towards that being Wastewater treatment/management.


Rising degrees of wastewater has another outcome. In addition to the fact that it is unsuitable for utilisation, it can blend in with other water sources and pollute them also. For example, wastewater streaming into waterways and contaminating it is the most harmful aspect of this scenario.

At that point when this wastewater runs downstream and joins other water sources like different streams, the pollution further spreads. Wastewater additionally saturates the ground/earth, debasing underground water sources. The outcome is that pretty much every water source is today intensely contaminated — from streams, rivers and wells to beach front regions.

This would be lamentable. Water is excessively significant for us to treat the present circumstance with anything short of farthest reality. Drinking water is fundamental for all people. Water is fundamental for animals, livestock, the food business, and farming. To a little degree, nature can manage normally delivered foreign substances like human and animal waste mixed with water. Nonetheless, the huge measure of wastewater today can’t be overseen ordinarily alone.

To summarise, some intense impact due to rising degrees of wastewater are:

–Destructive impact on river and marine life
— Acute shortage of drinking water
— Excess of certain destructive chemicals, some of which will remain persistent in the water source
— Harmful impact on groundwater
— Soil contamination
— Rise in ongoing medical issue identified with harmful synthetics like Lead and Mercury in every single living animal/human and thus rise in diseases like Cancer
— Rise of contamination in seaside region

The draft Master Plan for Delhi alone clearly says that water conservation features will have to be in-built in layout and building designs. Delhi is steadily moving towards water scarcity and achieving water security will require re-planning of the current supply oriented water planning approach. Water supply is not infinitely stretchable and cannot forever match the growth of population. Master Plan Delhi 41 says wastewater reuse is to be mandatory in the new development projects. 100% wastewater treatment and reuse is an important agenda of the Master Plan.


The major aim of wastewater treatment is to remove as much of the solid waste as possible before the remaining water which is hereby called effluent, is discharged back into the healthy environment. We need to manage wastewater in order to maintain our environment. We need to start recycling 30 % of India’s wastewater resources. It is extremely important to start recycling industrial waste. There is a shortage of water for rapidly increasing industrial, agricultural, and domestic demand. Two of the biggest cities in India, Delhi and Mumbai, are running less than half of the required number of waste treatment plants. Actual investment in wastewater needs to be increased to match industry standards. A private investment can provide a much needed stimulus to boost treatment of wastewater treatment.


The World Bank estimates that India’s total water and sanitation sector is worth $420 million, with an annual growth rate of 18 percent. Environmental guidelines have to be followed in setting up of wastewater treatment plants as well as to reduce the deterioration of available water resources. Clearly, wastewater management can no longer be ignored for the physical and mental well-being of our populace.

The current status of waste-water treatment in India is not the ideal one. There are umpteen number of challenges which are faced in India regarding wastewater management:

There is a lack of public awareness
There is no co-ordination or public-private partnership on wastewater management
A collective apathy is faced by some of the governments
A nationwide campaign is sorely missing
There is too much wastewater and not enough wastewater treatment plants.
Reusing sewage/wastewater provides us a great opportunity to reduce the burden on freshwater resources. This is a great method to reduce the demand for freshwater and also for solving the pollution and sanitation problems faced by us.

Wastewater treatment is a sustainable long-term solution to our nation’s water crisis. And how do we get about this? Daiki Axis brings to you Johkasou STPs which treat wastewater and make it fit for discharge to a normal environment.

Johkasou in Japanese language implies, decontamination Tank. Johkasou items are supported by the public authority of Japan and are widely conveyed across Japan as a piece of government strategy. In actuality, over 26% of Sewage in Japan is treated through Johkasou frameworks. More than 8 million Johkasou are running effectively in Japan and a few millions are introduced in different nations.

Using recycled water for various applications reduces reliance on increasingly scarce fresh water. Johkasou STPs are suitable for Indian conditions since they are portable by nature, can be rapidly deployed and have modular capabilities. They are suitable for individual homes, housing societies, hospitals, resorts, shopping malls, factories and offices etc. They have low operational cost and small capital expenditure. And this way, Johkasou STPs help produce large amounts of fresh usable water. It helps to reduce water pollution. Reusing recycled water provides a great opportunity to conserve water.
