Installation of a rewatec septic tank

Domestic septic tank installations

Septic tanks are used to treat and manage wastewater from homes and buildings in areas where there is no access to a municipal sewer system.

Installing a septic tank is a complex process that involves careful planning, excavation, and adherence to local regulations.

It's crucial to hire a licensed and experienced septic system contractor to perform the installation and to ensure proper functioning and compliance with local regulations.

At Premier Tech, we install (with our team of preferred installers) all our systems, either to replace an existing tank or to install a system at a new site.

Permits and regulations

Before starting the installation, it's essential to check with your local health department or relevant authorities to obtain the necessary permits and ensure compliance with local regulations for septic systems.

Site assessment and design

A soil test is conducted to determine the soil's permeability and suitability for a septic system. This test helps in designing the appropriate septic tank size and drain field layout based on the soil's ability to absorb and treat wastewater.


Once the design is ready, the installation site is excavated to accommodate the septic tank and the drain field. Excavation must be done with care to avoid damaging utility lines and to ensure proper placement of the components.

Septic tank installation

The septic tank is placed in the excavation. The tank is positioned at a specific depth to allow for the proper flow of wastewater.

Inlet and outlet pipes

Pipes connecting the septic tank to the building's plumbing system are installed. The inlet pipe carries wastewater from the house into the tank, and the outlet pipe allows treated effluent to flow to the drain field.

Drain field installation

The drain field (also known as leach field) is a network of perforated pipes or chambers buried in gravel-filled trenches. The treated wastewater flows from the septic tank into the drain field, where it is further treated and eventually released into the soil.

Backfill and compaction

The excavated area is backfilled with soil and compacted to provide stability for the septic tank and drain field. Care must be taken to ensure the tank and pipes remain level and undisturbed.

Inspection and testing

After installation, the septic system is inspected to ensure it meets the required standards and regulations. A final evaluation might involve conducting a percolation test to verify the drain field's ability to absorb wastewater.


Once the installation is complete, the area is typically landscaped, with the consideration of any required setbacks or surface water protection.
