PVC water tanks are commonly used for storing water. The types of PVC water tanks will be explained in the following.
Plain PVC water tanks
A plain PVC water tank is a container manufactured from PVC. It is usually used to store drinking water, rainwater, or recycled water. Plain PVC water tanks are available in various sizes and shapes to meet different needs. Their advantages are that they are lightweight, durable, and easy to install. Plus, they are often transparent or slightly opaque, allowing users to monitor water levels.
Reinforced PVC water tanks
The reinforced PVC water tank is manufactured from reinforced PVC. This material includes the strength-enhancing substance, stainless steel fiber. Such tanks provide better impact resistance and durability. In addition, they can maintain their shape and performance even in extreme weather conditions, making them suitable for commercial, agricultural, or industrial applications.
Modular PVC water tanks
Modular PVC water tanks represent a type of water storage tank, manufactured from modular PVC. It is a tank system consisting of multiple modular units. Such tanks can be assembled and disassembled according to actual needs. Therefore, modular PVC water tanks are especially suitable for temporary projects or occasions with limited space.
Underground PVC water tanks
Underground PVC water tanks are water storage tanks designed to be buried underground. They are manufactured from high-performance PVC materials to ensure adequate water storage and protect against external environmental factors. Underground PVC water tanks are usually used to save space or meet specific zoning requirements. They can be installed underground while providing large capacity.
Sizes and Capacity
When it comes to choosing the most suitable size for an application, it is essential to note that apart from the usual small domestic tanks that can be found in 500-5000 litre sizes. Large commercial ones can reach as much as 30,000 litres. Please note that this is the physical size of the tank, but the storage capacity can be different as well. If water is going to be stored for human consumption, then extra space will be required to prevent the tank from overflowing.
Optional Extras
Some suppliers may offer additional odourless, tasteless, and UV-resistant extras such as vented and unvented lids, which will allow for less evaporation and for excess rainwater to be drained out on the top of the tank. Toilets, dual outlets for pressure and gravity systems, and oversized flushes for quicker emptying will be optional as well.
Some large tanks also come with inspection hatches. The vented lid will enable air to enter the tank and be used for non-potable water systems such as stormwater harvesting and irrigation.
Gravity and Pressure PVC Water Tanks
The main difference between a pressure and a gravity PVC water tank is the method used to supply water. A pressure pump will give a higher water flow rate, while gravity-fed systems are more simplistic and less expensive to maintain. Typically, a pressure tank will have thicker walls, a higher water flow rate, and a costlier price.
Regular Cleaning
Drain the tank at least every six months and scrub the sides and bottom to prevent algae and bacteria growth.
Inspect for Damages
Check for cracks, leaks, or damages to the tank. Any minor damages should be fixed immediately, and any major damages may require the tank to be replaced.
Clean Inlet and Overflow Pipes
Regularly clean the pipes to prevent any bacteria and algae from entering the tank through the contaminated pipes.
Maintain Water Quality
Make sure that there are no insecticides, fertilizers, or any other chemicals in the soil that can be blown or washed into the tank. Avoid putting any chemicals into the water that may detract from its quality or create any harmful health issues. Try and use a stick to get any debris out instead of putting any chemicals in. Always use PVC pipe for any water transfers with no leaks.
Avoid Overgrown Trees
Make sure that all trees around the tank are trimmed back to prevent any branches from falling in and to keep sufficient sunlight to avoid algae growth.
Regular Pump Maintenance
For tanks with pumps, regular checks should be made to see if there is any wear and tear, especially rubber seals and the electrical connections.
Vermin Prevention
Make sure that no rats or birds enter the tank through any cracks or holes. All outlets should be screened to prevent any ingress of contaminants.
PVC water tanks have found usage in various industries because of their flexibility and durability. Here are some common usage scenarios for PVC water tanks:
Drinking Water Storage
Households, communal facilities, schools, and colleges use PVC tanks to store drinking water. This is usually the case when there is a pipe water supply, and the water quality is good.
Rainwater Harvesting
PVC water tanks are used to collect and store rainwater from rooftops or runoff. Special filtration systems and gutters direct the rain into the tank, which can then be used for irrigation, non-potable domestic use, or treated for potable use.
Industry Water Supply
Manufacturing, factories, and construction companies use PVC water tanks as a constant water supply. Industries that do not need high-purity water like semiconductor fab industries can efficiently use PVC water tanks for storage.
Agriculture and Irrigation
Agricultural farms use PVC tanks to store irrigation water. The tanks can also be used to rear aquaculture or for animal farming. The durable and flexible nature of the PVC tank makes it ideal for different agricultural uses.
Fire Protection Systems
Fire protection systems in buildings use PVC water tanks to store water for firefighting purposes. The tank is connected to firefighting equipment like sprinklers, hydrants, and firefighting pumps.
Hospital and Healthcare Facilities
Hospitals and healthcare facilities can use PVC water tanks for water supply, wastewater management, or storage of medical fluids. PVC's hygienic properties and ease of cleaning make it suitable for healthcare applications.
Food and Beverage Industry
The food and beverage industry uses PVC water tanks for the storage of ingredients, potable water, and additives. The food-grade PVC prevents contamination of the stored contents.
Temporary Storage and Transport
PVC water tanks are used for temporary storage and transportation of liquids in industries that are not harmful or hazardous. Examples include water for construction projects, cleaning agents, and fertilizers.
These are just a few of the many applications of PVC water tanks. Their flexibility and durability make them suitable for various uses in different industries and sectors.
When checking different suppliers of PVC water tanks, buyers will want to start by looking for tanks with good wall thickness. A good wall thickness ensures the tank will not bend or bulge when it is full of water, even amid adverse weather conditions. Wall thickness also adds to the tank's longevity and enables it to withstand the test of time. Buyers should also look for tanks with proper UV stabilization properties, which protect against the sun's rays. Such protection makes the tanks suitable for use in all kinds of environments.
Buyers should check how easy it is to install each tank. The tanks should have pre-drilled or customizable openings for simple installation of fittings and over the convenience of maintenance. Additionally, buyers should look for tanks that come with additional accessories, such as level indicators, ball valves, and tank fittings, which enhance operation and functionality.
When buying PVC water tanks in bulk, buyers should negotiate for discounts, as discounts can significantly impact their bottom line when reselling. They should also consider suppliers with generous return policies. This way, they can return the products if they do not meet the required standards. Checking customer reviews can also give buyers a good idea of what other customers think about a particular supplier. If most customers are dissatisfied, it is safe to choose another supplier.
Buyers should also choose tanks compatible with water treatment systems. Such tanks will prevent the formation of any substance that can alter water quality, making them suitable for storing treated water. Additionally, buyers should opt for tanks that comply with local regulations concerning material and construction standards. This not only ensures the buyers’ customers’ safety but also fosters compliance with industry standards.
