In numerous urban areas and regions with scarce water resources, underground water tanks have developed into a solution of paramount importance to satisfy the population's water necessities. These tanks are capable of storing substantial quantities of water, thereby contributing to a stable supply even in dry seasons or in the occurrence of natural calamities that may disrupt the regular provision of water. Furthermore, underground water tanks are not merely limited to the storage of potable water; they may also be utilized to conserve rainwater or even recycled water, which constitutes an additional benefit in terms of the management and preservation of water resources.
Septic tank
An underground septic tank is a system for wastewater treatment and disposal. It is used in areas without connection to a centralized sewage system. The septic tank is made of concrete, fiberglass, or plastic, buried underground. It collects wastewater from bathrooms, kitchens, and laundry. Inside the septic tank, solid waste undergoes separation. Heavy solids settle at the bottom, forming sludge. Lighter materials, like grease, float to the surface, forming scum. Liquid effluent flows out of the tank and into the soil for further treatment through natural processes. Proper installation and maintenance of septic tanks is crucial to prevent pollution and protect public health.
Materials
Underground water tanks are available in various materials, including concrete, steel, fiberglass, and plastic. Each material offers distinct qualities, such as durability, resistance, and adaptability, ensuring that the tank can effectively meet specific needs and environmental circumstances.
Sizes
Typically, the size of the underground water tank can range from 2000 liters to 5000 liters. The capacity options are 2000, 3000, 4000, and 5000 liters. The tank can also be customized based on specific requirements. Choosing the appropriate size allows for storing as much water as is necessary while optimizing space utilization.
Installation method
There are two types of underground tanks: the one-piece style and sectional style. The one-piece style is installed in a single piece, and the sectional style is installed by piecing together multiple sections. The installation method offers flexibility in tank construction and installation, accommodating different requirements and situations.
Access points
Underground tanks usually have access points, such as manholes and inspection openings, for monitoring and maintenance. These access points provide convenient access for professional personnel to ensure the proper functioning and maintenance of the tank.
Protection against corrosion
As underground tanks may be susceptible to corrosion due to damp environmental conditions and prolonged contact with water, they often come equipped with anti-corrosion coatings or cathodic protection. Such protective measures can effectively extend the service life of the tanks.
Regular cleaning and disinfection
Regular cleaning and disinfection of underground water tanks is essential to ensure the quality and safety of stored water. Periodically draining the tank, thoroughly cleaning its interior surfaces, and using approved disinfectants for sterilization can effectively prevent the growth of bacteria and algae, thereby reducing the risk of waterborne diseases.
Inspection of facilities and equipment
It is vital that the facilities and equipment related to the functioning of the underground water tank, such as supply pipes, valves, and pumps, are regularly inspected and maintained. These checks should include identifying issues, such as leaks, clogs, or malfunctions, and promptly resolving them. Such practices optimize the utilization of water resources and ensure the efficient operation of the entire water supply system.
Paying attention to surrounding environment
The management of the surroundings of underground tanks also plays a pivotal role in their maintenance. Ensuring that the ventilation and drainage systems around the tanks are functioning correctly helps to prevent problems, such as moisture retention or leakage. Furthermore, timely clearing away surrounding vegetation and debris can reduce the risk of pollution and blockages, thus safeguarding the water quality and operational efficiency of the tanks.
Underground tanks have versatile usage scenarios for industries that demand large storage capacities or need to store materials securely and discreetly. Here are some common usage scenarios for underground tanks.
Petrol stations
Petrol stations have been the most traditional and still major use for underground tanks. Usually, there is a large underground tank under the fuel dispensing area to store various types of fuels. The design of underground tanks can keep fuels away from the sun and reduce environmental pollution.
Industries
Industries can utilize underground tanks to meet specific needs. The tanks used in the industries are generally large and made of high-strength materials. Special shapes can be adopted to suit different production processes or site conditions. For example, some factories may need to install large underground tanks to collect and treat wastewater. Therefore, industrial underground tanks can also be equipped with advanced monitoring and control systems to realize automatic management and improve operation efficiency.
Agriculture
In the agricultural field, underground tanks can be used to store water or fertilizers. For example, under dry climate conditions, farmers can use underground water tanks to collect rainwater or store irrigation water to ensure adequate water resources for crop irrigation.
Food and beverage storage
In the food and beverage industry, underground tanks can be used to store raw materials, such as oils, syrups, etc. Underground tanks can offer better temperature control and protection for these easily damaged substances, thus ensuring product quality.
Drinking water storage
In public utilities, underground tanks are crucial for storing clean drinking water. Whether in urban centers or remote rural areas, these underground tanks provide secure storage for drinking water and are essential for maintaining the water supply system.
Rainwater harvesting systems
Rainwater harvesting systems use underground tanks to store harvested rainwater. The tanks are usually placed beneath the surface, connected to rainwater collection systems such as gutters and pipelines. This stored rainwater can be utilized for non-potable water needs, such as irrigation, toilet flushing, and cleaning, reducing dependence on municipal water supplies.
Wholesale buyers shopping for underground tank solutions for commercial, industrial, or large-scale residential projects should partner with suppliers who are willing to share the tank's specifications in detail. In particular, the following five factors need to be considered before placing a bulk order.
Purpose:
Specify the purpose of the tank, such as the storage medium, its characteristics, and whether it will be located in an area with high traffic or where the temperature can drop below freezing. Choose materials that can withstand the liquid's corrosiveness, are leak-proof, and are compatible with the site's soil conditions.
Capacity:
Select the tank's size based on how much of the liquid needs to be stored and the space constraints. Keep in mind that larger tanks typically cost more and may need additional excavation and installation efforts.
Design:
Choose an underground water tank design that is suited for the type of water one plans to harvest or store. For example, in areas with rainfall, a rainwater harvesting tank can be constructed, and in areas with recurring water scarcity, a groundwater recharge tank should be considered. Focus on a tank that allows for efficient filtration, non-algal growth, and easy flow of water to the areas where it is needed. In places such as commercial properties where large amounts of water are used every day, a large underground tank with a tower to facilitate pumping to different floors should be considered. Choose a design that has sturdy lids that can easily bear the weight of vehicles running over them.
Installation process and cost:
Installation costs vary depending on tank type, soil condition, local regulations, and labor costs. Include excavation, tank placement, connection of plumbing or infusion systems, backfilling, and testing of the system. An expert should be included to conduct a detailed soil and water table analysis so that the best tank type and design can be selected. If the local authorities have specified a tank design, it should be adhered to, as fines or costs due to non-compliance will have to be borne.
Sustainability:
In today's environment-conscious world, how the tank is made and what happens when it reaches the end of its useful life should be kept in mind. Is the tank recyclable or does it end up in a landfill? Partner with suppliers who are committed to sustainable practices and who can tell buyers about the tank's carbon footprint.
