Market Insights

The septage tank is essentially an underground biological decomposition tank for water treatment. This water treatment process sees the help of natural processes and proven technology to reduce wastewater from household produce like bathrooms, laundry, kitchens, and drains. The simple septic tank is the simplest type of septic tank, usually made of fiberglass, concrete, or plastic.

It is an on-site sewage facility, wherein the sites of premises found in unsewered areas treat the sewage here. Other similar kinds of water treatments within the scope of OSSF include aerated wastewater treatment, biofilter systems, composting toilets, and activated sludge systems. The OSSF safeguards public health and safety, preserves and enhances environmental quality, and preserves the community amenity.

Recently, the Kozhikode Corporation has inaugurated a project of a 4 scientific septic tank of 5.1 MLD total capacity on the premises of Medical College Hospital. This is to guard the staff and the students of the medical college and keep the premises clean and sanitised.

How is AI Changing the Septic Tanks Market?

The septic tanks market can be improved through artificial intelligence in terms of energy efficiency. Technologies like Endobot and Swasth AI have the functions of pipeline diagnostic, acting as devices that can detect and eliminate contaminated water, wastages, and sewer spillage which often goes unnoticed due to underground issues such as leaks, blockages, and tree roots.

Solinas is an AI-based pipeline defect identification and assessment service that saves costs, reduces time for resolution, and improves the supply of drinking water to the whole city, which supplies drinking water to over 1000 households. The recognition of the defects in the sewage pipeline for the Sewerage and Infrastructural Development Corporation (SIDGCL) results in faster and more cost-effective solutions.

Segment Analysis

Material Segment

The major share of the septic tanks market in 2024 is from the plastic segment. The high demand for safe and easy-to-clean septic tanks boosts the plastic material septic tank. Polyethylene plastic septic tank is the structure used by the industry for the past 30 years. Plastic tanks are light and easy to install compared to concrete tanks. They face less damage due to water-damage defects and corrosion because of acidic soils. They crack less as compared to other tanks.

People having new or replacement projects prefer plastic tanks. The lifespan of a plastic tank is more than 32+ years.

Capacity Segment

The 1000-5000 liters septic tanks market sector had the largest share in 2024. The capacity of septic tanks varies with variables such as daily wastewater, volume by local regulation, and occupancy of buildings. A recommended capacity for a septic tank close to about 1,000 gallons is advised for a residential premise. The number of bedrooms in the house or people is used to approximate an adequate capacity of the tank.

Application Segment

The residential application segment dominated the for global septic tanks market in 2024. A septic tank is essential for a house and workplace because it is the safest and most effective treatment of wastewater.

Market Scope

Market Dynamics

Driver: Augmented usage of septic systems in rural areas

Rising population, urbanization, and it is often cheaper for people when they treat wastewater closer to where they are collecting it. A blog by Asian Development speaks about how women are key in rural areas when it comes to sanitation. A civil society, 'The Vietnams Women's Union,' implemented campaigns and promoted the adoption of septic tanks in villages, Vietnam.

It was discovered that they are likely to buy if and when a neighbour talks or if they have spoken to the women volunteers from the NPO, it was therefore concluded that people dwelling near them influenced their decision to buy a septic tank. Besides, it was observed that the households in which the female members decided in the house were the most vulnerable and likely to have a septic tank installed.

Control: High cost of concrete septic tanks

Concrete septic tanks have longer life period than plastic but shorter than steel. Steel tanks rust very fast and are therefore not used anymore nowadays; concrete tanks cost much more when purchasing and installing compared to plastic tanks. Concrete septic tanks have a longer life and can be said to have high durability in comparison, thereby making it even more costly.

The concrete tanks are bulky and thus are heavy, taking much longer in installation and require a lot of machinery, making the cost highly expensive. It is very essential to clean and maintain the septic tank, especially concrete tanks as they form cracks with time which also costs a lot which people in rural areas might be unable to afford.

Opportunities: Smart solutions for septic systems

Septic tanks have been very technologically advanced in recent times. They have many advantages which are not there in traditional tanks. Another eco-friendly septic tank is available that do not allow pollution caused by these conventional ones. Moreover, smart tanks are more flexible and can also sustain earthquake and other natural calamities.

Smart tanks are suitable with most of the soil types also. Detection of issues in the traditional septic tanks used to be difficult but real-time data and detection of problems by smart septic tanks allow scheduling of repair work. There exist water level monitors for septic tanks that can monitor if the water is too high or too low in septic tanks.

Some of the challenges are; high raw materials in septic systems

Obviously, the quality raw materials are used in making septic tanks. Apart from shoddy materials, poor design and installation can also reduce the septic tank's lifespan and even make it fail. Modernized septic tanks are of concrete, steel, fiberglass, or polyethylene. Concrete tank materials usually cost much more than polyethylene tanks.

The cost of a concrete septic tank varies between USD 700 and USD 2,000; the installation is also very expensive; as a whole, the entire cost of a concrete tank may be several times above other raw materials.

Regional Summary

Asia Pacific accounted for the largest share in the septic tanks market in 2023. Asia Pacific is continuously developing in respect to urban wastewater management. In urban Asia, septic tanks are used by approximately 80% of the population.

For Asian countries, the priorities of their government are more on infrastructure projects that advance economic activity, such as power plants and ports. Compared with sewers, more so with water treatment systems, relatively fewer flush and pour-flush toilets are shifted into septic tanks. It is easier and cheaper to implement them in densely populated areas because of their practicality.

North America is expected to be the fastest-growing market for septic tanks in the forecast period 2024-2034. Decentralized, small community cluster systems are used by more than one in five households in the US. Even so, estimates suggested that only one in four homes had a septic tank, as per the U.S. Census Bureau. Just 10% of homes in California are on septic.

Recent Developments

• Homosep Atom, the first robotic garbage collector launched by India, was released in February 2024. The Union Science Ministry supports this action in the development of a robotic solution. This action would remove hazardous and life-threatening job of scavenging done by humans.

Growing Factors in Market

• Cost-effective: The user saves on water bills since it does not incur charges for sewage change.
• Environment-friendly: Septic tanks are a greener solution for the environment. It does not use chemicals used in other systems of sewage.
• Preventive measure: It prevents underground water contamination due to the absence of any leakages. It uses natural filtration media, which is helpful for plants and animals. It cleans the bacteria.
• Suitability: It minimizes carbon footprint and allows the converse water by refilling it beneath the soil surface.
• Durability: Provided the installation and maintenance is carried out properly, a septic tank has a life of 20-40 years.
• Flexibility: Septic tanks are available in various sizes and shapes; therefore, a consumer can select any project according to his requirement, usage, and budget.
