Our Septic Tank Upgrade Workflow follows 4 Simple Steps

Site Visit

The first step is to give us a call and have one of our experienced staff discuss your requirements and offer advice. If it is necessary, our engineer can call to your site to assess your requirements and offer further advice. All of this is provided free of charge.

Design & Quote

After a full site assessment, our engineer will begin the process of designing your site specific system. Once decided on the appropriate system for your site, we can provide you with a detailed quotation. Again, all of this is offered free of charge.


Depending on your requirements, installations take approximately 1 hour, or where the customer requires a complete turnkey package, we arrive on site with our own machinery and begin the groundworks. Turnkey packages will offer you the most cost effective solution.

Commission & Certify

Once the installation is complete, we will provide you with the required certificate of compliance. This is your guarantee of quality and offers further reassurance that you have received a top quality product from us.

Not All Septic Tanks Need To Be Upgraded

It is never a pleasant experience when a septic tank breaks, and there is often an incredible amount of pressure to get the situation resolved as quickly as possible. At times like this, consumers are well advised to stop, take a deep breath and count to ten. A broken septic tank may seem like the end of the world, but it is actually a somewhat common experience. Instead of panicking and calling the first septic repair crew in the phone book, consider Corcorcan Precast Tanks. After all, very few wise decisions are made by people in a hurry. Instead, carefully thought out decisions are typically the best, and a wise decision in this case might save one a substantial amount of money.

For the individual homeowner the cost of replacing a failing septic system can be a real issue with replacement tanks and leach-fields. Potential ecological impacts of failing or poorly installed on-site wastewater treatment systems are varied, but often include eutrophication of waterways with blue green algae and bacterial contamination of aquatic systems.

How Do I Know If My Septic Tank Is Failing?

To make everything very clear we have broken down the signs of septic system failure into three separate groupings.

1. Issues in the Home

- Backup of sewage in your drains or toilets – this can often a black type liquid with a disagreeable odor.
- Decreased flushing of your toilets
- Decreased drain flow from showers and sinksr.
- Unpleasant odors in your home

2. Issues with your Tank
- Over-flowing or near over-flowing septic tank
- High solids accumulation in the septic tank

3. Issues with the Leach-Field and Surrounding Environment
- Water accumulating / wet patches in the percolation area.
- Lush green grass through-out the year, especially if the surrounding garden is significantly different.
- Presence of contamination (e.g. nitrates, bacteria) in your well water is potentially a major health hazard and is a very clear indication that your septic system is not performing adequately.
- Accumulation of algae and aquatic weeds in adjacent lakes, ponds, streams is a clear indication that your septic system is under performing and contaminants / nutrients are migrating from your septic system.
