Whether for private or commercial use, storing high volumes of water can be a challenge. Depending on your constraints as an individual or a business, you may feel limited in your options. However, water storage is actually more flexible than you may imagine, and there are many different solutions available to you depending on your needs. Here are the three main areas to look into.
These tanks may be the most standard and basic solution, but that's for a reason; they are perfectly competent as storage, and they are highly cost-effective. Available in many different capacities, these tanks can be stored both underground and overground depending on your wishes and your space constraints; as the most common options, these are also the easiest to maintain and to install into existing piping systems. There are also insulated options if this is something you require.
If you need your water supply to be portable, then water bladders may be the ideal option for you. These flexible but durable containers are easy to fill and can be placed into a truck-bed or any other location and transported to wherever it is required. However, as the bladders do not hold an upright form, they may be difficult to store when not in mobile use.
If you're looking for an upgrade to a basic standing tank, or if you require your water supply to be extremely consistent, then a sectioned tank is a great option for you. These tanks contain several sections; if you wish, each section could contain water of a separate pH—or even temperature, if they're individually insulated—and can be drained individually to allow for maintenance without interrupting your usage of the other sections. Due to their complexity, they are perhaps superfluous to the needs of a private household, but their time-saving capability and versatility are great assets for business users.
In short, you should first decide whether your water supply should be fixed or mobile, how much space you have to dedicate to the storage, and your specific requirements with regards to water usage and access. Based on your answers to these questions, one of the above categories should make the most sense—but you could also consider a combination. For example, if your budget permits it, you could own a high-capacity standing tank from which you fill a mobile bladder on a daily basis. It all depends on your individual needs; speak to a specialist supplier if you are uncertain, and they will be happy to advise you.
