Installing a new septic tank?
If you are in the process of installing a new septic tank by yourself here are a few steps that may be of some use to you. Advices only for correct installation speak to the manufacture.
- You will need to excavate the ground to the correct size of the septic tank
- Put a concrete base at the bottom of the hole you have just excavated. You may require putting some hold down straps within the concrete; your septic tank provider should let you know whether this is necessary.
- With a crane slowly lower your septic tank into position within the hole.
- If you were required to use hold down straps you should now install the straps around the septic tank to stop it rolling around while it’s in the ground.
- Once you have installed the straps you will now need to fill the septic tank with water which should be about 30-40cm deep, ahead of backfilling.
- Now backfill the excavation with concrete or with a suitable material that is approved by the septic tank company. Remember to only half fill it as you still need to connect pipes.
- Now you will need to connect the inlet and outlet pipes to the specified areas of the drainage system.
- Now backfill with concrete or any other suitable material minimum being about 300mm above the tank. You should now only be able to see the hatch. I would also advise in having a galvanised steel lid so if someone stands on top they want fall in.
- Level off the ground so that people or you don’t trip up over the hatch and fall in. if you have installed a large commercial septic tank then the tank should be able to have concrete on top. If it’s a domestic septic tank then I would suggest laying grass on top. And make sure you have a septic tank emptying service every year to ensure good working order. This is only advice. I would recommend getting a professional to do the job myself.
