What Is a Concrete Cistern Tank?
A concrete cistern tank is a large tank for collecting rainwater collected from impervious surfaces for domestic use or for consumption. The rainwater collected in a concrete cistern tank can be used for two purposes: domestic use and consumption. Household uses include water use, flushing toilets, watering gardens, cleaning laundry, and washing cars.
The use of rainwater in a concrete cistern tank assembled to perform such general tasks can reduce the costs associated with water delivery in a conventional supply system.
Secondly, rainwater can be used for consumption in the collection tanks. This application is suitable in places where there is no continuous supply of drinking water. Ideal for locations such as rural agricultural areas or backwoods campsites etc.
A cistern tank is a waterproof tank for storing rainwater. The capacity of a modern cistern tank ranges from a few litres to thousands of cubic meters, its composition effectively creating covered reservoirs.
Concrete Cistern Tank Is Best Material to Store Water
A concrete cistern tank is widely used for rainwater harvesting in urban, semi-urban and rural areas. Concrete water tanks are used to store plenty of water, although smaller options are available.
This type of tank can be properly installed for aboveground and underground installation or poured on-site in your plot area.
If space in your building plot is a concern or you need to store a large amount of water, a concrete cistern tank in the basement or above ground can be an ideal option.
Cracking is usually the most common complaint in a concrete water tank, but most concrete tank manufacturers have a solution.
Precast Concrete Cistern Tank
The precast concrete cistern tank is delivered in a fully prepared form. It requires a crane to unload it from the truck on location. This precast concrete tank is installed on a prepared base of compacted crusher dust or compacted sand.
Precast tanks for large water storage come in one to three pieces. It is made by sealing the sections of a prefabricated tank together in various ways on the spot. A ring made of rubber or synthetic material is used for sealing. It is placed in the groove of the lower section with sealant before placing it on the upper half of the section of the precast tank. The inside of the tank is then sealed with sealant to prevent water from leaking out.
Precast concrete tanks serve as an environmentally friendly alternative for water storage. It also provides cool, clean and pure water to the user as it is free of chemicals and algae. Each precast tank is tested for water leaks. After testing, they are waterproofed using specially developed nano materials.

Features and Benefits of Precast Concrete Cisterns Tank
- It offers stronger, more durable watertight construction than any other type of tank.
- The oval design with its minimally flat wall elements gives high strength.
- The tank includes riser footsteps such as stainless steel, hinged, lockable drip-proof, etc. for safe landing inside the maintains.
- Drinkable PVC fittings in the precast tank for filling water are cast-in-place on top of the tank surface.
- Brass pipe fittings are laid in the wall of precast concrete and are installed outside the wall with brass fittings for connection with flexible piping. (Note:- Galvanized steel riser cover or galvanized fittings are not used inside the tank as they can produce toxic compounds with water).
- Standard plastic-coated safety steps are installed for entry/exit into the precast tank.
Advantages of Concrete Cistern Tank
- This type of Concrete Cistern Tank serves to store water with a very long life.
- It can lay the foundation for the installation of a pond in the parking lot or garden to take advantage of rainwater harvesting.
- It provides more load-bearing capacity than other types of material. So as to allow it to be installed in the driveway and parking lot area.
- It can be a solution for large quantities of rainwater as economical underground storage.
- Slightly acidic rainwater can neutralize damage to concrete walls.
- Food grade, NSF approval for drinking water storage can be obtained if a liner system is used inside a concrete cistern tank.
- This type of concrete cistern tank can be easily repaired if cracks develop.
- It maintains the same temperature of stored water throughout the year.
- Concrete Cistern Tank can be configured in any shape, depth, layout for custom installation for the project.

Disadvantages of Concrete Cistern Tank
- concrete cistern tank has to be designed according to proper planning. It can be expensive to change the design once it has been made.
- Its installation and excavation require heavy equipment, and heavy machine access can be difficult at some small project sites.
- Sometimes the movement of the surrounding soil can cause cracks in the concrete pool.
- This type of system can be costly for storing small amounts of water.
- The precast concrete cistern is not readily available. Precast concrete cistern prices can include expensive shipping costs.
Concrete Cistern Cost
Installing an underground, 5,500-gallon water storage capacity concrete cistern can cost between $ 17,000 and $ 21,000. These costs include things like excavation backfilling, grading and water filtration etc. The cost of pouring concrete from this type of concrete cistern tank is about $ 4 per cubic foot; this does not include labour.
