How To Choose The Right Underground Water Basin For Your Project

There are infrastructure and landscaping projects that call for an underground water basin. Choosing it isn’t rocket science, but it surely requires a good knowledge of how these systems work and of the technical details of your project. This article shows you what to take into consideration when searching for stormwater retention basins or for any similar water storage system.

First of all, you should be aware that not all water storage tanks are suitable for underground installation. If you don’t want to build a concrete basin, you’ll need to research the types of plastic tanks that can be buried. You’ll find out that the best basins are the ones that feature a ribbed design. This is how they support the surrounding soil.

The purpose of the water tank will also influence the choice of materials. If you want it for drinking water storage, you’ll need to make sure it is made from FDA approved virgin polyethylene plastic resins or similar materials. If you need an underground tank for stormwater retention or for harvesting rain water, you won’t have to worry about choosing non-toxic materials, as you won’t be drinking that water anyway.

If you want to place your underground water basin under a driveway or sidewalk, you’ll have to change your plans, as this will probably void your warranty. Always check with the manufacturer of the basin whether you can install it in your desired location. Your available space will probably determine the size of the basin, as well. When it comes to water storage, you’ll be fine with any size of tank. However, in case of stormwater, you’ll need to make sure that you choose the right size, in order for your system to be effective. A specialist will be able to assess your location and your needs, and will make you the right recommendations. If you don’t have a specialist to give you advice, you can check with the different suppliers and manufacturers of such equipment to see if they can provide you with the guidance you need.

Also consider doing some research to find out what would be the ideal bedding or backfill for your cistern. More often than not, a mixture of sand and gravel will do. This mixture is known as “pea gravel” and it can secure adequate support for your underground water tank. If you don’t know how to prepare this bedding, you can outsource this job to experts. Anyway, you may want to search for a contractor to sell you the basin you need with all installation works, in order for you to have it up and running without the need to hire anyone else.

In conclusion, choosing the right underground basin is a matter of careful research, and of knowing your priorities and the specific requirements of your project. Always check out several offers from different manufacturers, as this is the best way to find the quality you expect at a reasonable price. Besides, check out the warranty conditions, as well as any other details that may influence your experience and your satisfaction level.
