Types of underground water storage tanks

Underground water storage tanks are designed to store a large quantity of fluids. They are used widely in commercial and industrial sectors.

• Plastic underground water storage tanks

  Plastic underground water tanks are fabricated from strong, resilient plastic materials. The materials are usually lightweight, making them easy to handle during installation. Plastic underground storage tanks are available in different sizes and shapes. This makes them able to meet distinct requirements. These tanks have a natural resistance to corrosion and rust. Thus, they can preserve the quality of water for a long time. Besides, plastic underground water storage tanks are also cost-effective options for many businesses.

• Fiberglass underground water storage tanks

  Fiberglass underground water storage tanks are alternative options for storing water underground. These tanks are made from composite materials that live glass fibers and resin. Like plastic tanks, fiberglass underground water storage tanks are also corrosion-resistant options. They can also prevent leaks and keep water clean. Fiberglass tanks usually come in larger sizes. Thus, they are suitable for commercial and industrial applications that need large water volumes.

• Concrete underground water storage tanks

  Concrete underground water storage tanks are stable and strong options for underground water storage. These tanks are made from cast-in-place concrete or precast concrete. Concrete tanks have great durability and resistance to harsh environmental conditions. Because of this, they have a very long service life. Concrete underground water storage tanks are usually chosen by large enterprises. They are also ideal for industrial applications that require large-scale water storage solutions.

Specification and maintenance of underground water storage tanks

Underground water storage tank specifications vary depending on the type, but certain key features are common.

• Capacity

  The capacity of underground water storage tanks is typically described in liters or gallons. It indicates the maximum volume of water that the tank can hold. The capacity of underground water storage tanks actually varies anywhere from 1000 to 1,000,000 liters.

• Dimensions

  For buried tanks, dimensions indicate the tank's length, width, and height. Rigid tanks usually come in cylindrical and rectangular shapes. Buried tanks have to be spacious enough to accommodate the water and the tank itself.

• Material

  Underground water storage tanks are made of various materials according to their types. For example, concrete tanks are made of reinforced concrete, which contains steel bars or wire mesh for added strength and durability. Many plastic underground water tanks are made of high-density polyethylene. HDPE is a very tough polymer that is resistant to impact and UV radiation.

• Access

  Underground water storage tanks usually have access ports or chambers located above the tank. Access ports are circular openings with secure covers. Access ports allow for tank inspections, maintenance and cleaning of the underground tank.

• Operating Requirement

  Many underground tanks should be installed below the frost line so they won’t freeze during winter. Tanks should also be placed away from stormwater runoff or contaminants so as to prevent water pollution.

Regular monitoring and maintenance are essential for the longevity of the underground tanks. The following is frequently requested care and tank service.

• Regular inspection

  Regular inspection of the tank and its parts is essential. During concern or part damage, immediate repairs are made to minimize the possibility of water leakage or contamination.

• Cleaning

  Clean the inside of the tank regularly. Doing so helps remove sediment, debris and potential contaminant buildup. For tanks with access ports, use cleaning equipment such as vacuums or brushes to clean those inaccessible areas. Also, dispose of the dirt or debris in accordance with local regulations to prevent secondary pollution.

• Protection

  When undertaking maintenance or repairs to underground water storage tanks, use materials and methods that do not damage tank integrity. For example, use non-toxic, biodegradable cleaning agents to protect the quality of the water in the tank. Additionally, make sure that the access ports are securely closed after maintenance to prevent any unauthorized entries.

Scenarios of underground water storage tanks

Underground water tanks were primarily used for storing water. Generally, water from rain, groundwater, surface runoff, and other sources could be harvested. Particularly, this method served the arid and semi-arid regions well, as water was available in abundance underground.

In urban areas, infrastructure development frequently competes for land. Underground tanks offered a solution to store water without occupying valuable surface space. Also, flood management and control were pressing priorities. By storing excess rainwater below ground, tanks helped mitigate flooding, reduced the financial burden on municipalities, and protected urban infrastructure.

Industries often faced the challenge of managing process water, cooling water, and wastewater. Underground tanks provided a practical solution for storing and treating process water close to production facilities. The agricultural sector benefited significantly by utilizing underground tanks for irrigation in dry periods. The tanks ensured a consistent water supply for crops, livestock, and other agricultural activities.

Underground water storage also found applications in fire prevention systems. By strategically placing tanks below ground in areas with high fire risk, firefighters ensured an adequate water supply for firefighting purposes. The tanks were easily accessed through underground piping, and this infrastructure operated seamlessly out of sight but effectively fulfilled its crucial role in fire prevention.

In addition to these traditional uses, the role of underground water storage tanks continued to expand. Now, they served as valuable resources for water recycling and reuse systems. Through filtration and treatment processes, stored water could be repurposed for non-potable applications like landscaping irrigation, toilet flushing, or industrial cooling, contributing to sustainable water management practices.

How to choose underground water storage tanks

Choosing underground water tanks for storage will depend on a variety of factors, including the intended purpose and the location of installation, among others.

• Size and volume

  The size of underground water storage tanks can vary, but it is important to ensure that the tank selected can adequately meet the supply demands. The number of users and their daily consumption can be good determining factors in calculating the tank volume that will be needed. Other considerations to make are the frequency at which the water will be provided and the amount of space available at the intended installation site.

• Material

  For durability, it is important to consider the material of the water storage tank. Tanks made from concrete or polyethyleneare are popular choices in underground water storage. Concrete is a naturally strong material with excellent resistance, making it suitable for long-term use underground. Concrete tanks also do not have chemical leaching, giving the stored water high purity. On the other hand, high-density polyethylene (HDPE) is a lightweight plastic material known for its durability with corrosion and impact resistance. HDPE tanks are easy to install and can adapt to different soil conditions.

• Installation

  The installation of the underground water tank will also play a role in how well it functions. The tank must be properly placed so that there is no danger of collapse or leakage from the surrounding soil. If the tank is made of HDPE, it must be securely connected with seals that do not allow water to seep through. Moreover, any kind of tank will need to have a system of filters and pipes so that the water that goes into it is clean even before storage.

• Cost considerations

  While cost is an important consideration, it is critical not to prioritize cost over quality when choosing an underground water tank. Investing in a high-quality tank can provide long-term benefits and prevent costly repairs and replacements.
