Underground Water Tank Installation Tips You Should Know

Most people think that an underground water tank installation is a complicated project, but it's not. Provided you get the right tools and know the basic steps, everything should go smoothly. Of course, you always have the option of hiring an installation expert if you aren't sure about your DIY skills or capabilities.

This post will share the key installation steps to help you ensure everything is done right. Because the tank is being buried, the installation crew must be cautions every step of the way. The warning signs on the tank lid must also be read before the installation process begins.

Dig up

Start by measuring the tank's length and width then add some extra twenty-four inches on both sides and ends of the tank. Mark these dimensions on the surface then start digging. The depth of the hole should offer a minimum of six inches cover over the tank's top.

Prepare the new tank's base

Any roots that may be found at the base of the hole need to be removed. Place the tank bedding material — usually its packed pea gravel. You may also use native or sandy soil, but it needs to be free from sharp objects like rocks, be flowable, and be compactable.

Set the tank

Put the tank at the centre of the hole using an excavator or crane, then push it back and forth. This lets the pea gravel base fill in any ribs along the tank's bottom. The levelling of the tank needs to be done before the straps connecting the tank to the crane are removed.

Install connections and risers

Bulkhead fittings should then be installed. You need to plumb using a flexible hose from the bulkhead fitting to prevent movements that may break the fitting or exert additional stress on the tank. The tank must also be vented. This ensures that the tank isn't sucked in whenever water is getting pumped out. The risers should then be added. If this is too complicated, consider contacting a professional.


Once the tank is perfectly installed, it's time to add the backfill. Start by filling the centre of your tank using pea gravel or any material that has been recommended, then compact it. It's crucial to ensure that all gaps are completely filled. Each twelve-inch layer of the backfill must be compacted well before the next layer is added. Remember to compact every area around your tank and under the pipes.
