Some homeowners and facility managers prefer to harvest rainwater and store it underground as opposed to utilising vertical tanks above ground. It might be an aesthetical requirement or as a consequence of limited space.
Underground storage tanks from RotoTank™ can be used for storage of municipal water, rainwater harvesting, grey water, conservancy water waste or any other liquid which may be stored underground legally. It is critical that installation instructions be strictly followed.
The Tanks are fitted with a screw-on threaded 450 mm manhole lid included for easy access and inspection. It can be installed in series for large installations.
Storage Tanks have thicker and stronger walls to prevent it from collapsing. The materials are food safe (FDA approved plastic for potable water).
BENEFITS OF AN UNDERGROUND PLASTIC TANK
The following considerations may assist a prospective customer in his / her decision to install an underground storage tank as opposed to an above ground rainwater harvesting tank. Some of these considerations are:
3. RotoTank™ underground storage tanks are equipped with child safe manholes and it may be covered completely with a decorative manhole cover if needed.
4. Because the tank is completely sealed and buried it cannot be infested with any contaminants which may often be found in vertical tanks.
5. RotoTank™ has a large variety of sizes and can provide its customer with any size of tank ranging from 300lt up to 12500lt for underground use.
6. A plastic underground tank is less costly to install than brick-built tanks. It is unlikely ever to leak if installed correctly, while mortar and brick tanks does crack over time.
Installing an underground water storage tank is simple when you have the right tools for the job. In this article, you will learn a simple 6-step installation method that includes an explanation of the recommended materials and machinery to be used. Using the correct backfill material to bury a polyethylene tank is particularly important as it will lengthen the life of the tank significantly. Because these tanks are getting buried, you must also be extra cautious about where you are installing them. The geographical elements of certain areas may require you to consider extra cautionary steps.
Using the correct backfill material will minimize the possibility of the tank collapsing. This is an extremely critical part of installation and must be followed. A one-to-six ration of river and cement mix is required to encapsulate the tank. If the geographical area is prone to high water table levels during the raining season this ratio may be increased. When mixed care should be taken not to ad water and make a wet mix, it should be a dry mix for filling the bottom of the hole and around the tank. It is important that all material must be free of sharp objects that could cause damage to the tank.
Now you have a basic idea of how to install an underground water storage system, you’re set to go! Regular checks of an under-ground tank is recommended to ensure nothing out of the ordinary has happened. If you are using your underground tank for drinking or potable water, you should also make an effort to monitor the water quality to be sure no debris has entered through the tank lid.
