Tricel Novo Wastewater Treatment Plant

The challenge

The project

During the autumn of 2017, Depawater received an inquiry from a homeowner who required pricing on a wastewater treatment plant for his new four-bedroom bungalow. The self-build project was well underway; indeed, the percolation test had already been carried out, and the consent to discharge approved. Following the initial phone call, a site visit got carried out and the price quickly agreed.

How we helped

The results of the site visit identified the Tricel Novo UK6 Plus domestic sewage treatment plant (gravity) as the best solution. This plant works in conjunction with a percolation area installation consisting of four 10m (L) x 600mm (W) x 600mm (H) trenches. Inside each of these four trenches is a 100mm twin-wall surround of perforated pipe covered in 150mm of cleaned/washed bluestone.

The Novo is the sewage treatment plant which most suited the requirements of the client’s site. It was also the preferred choice of the homeowner due to reliability, cost-effectiveness, CE certification, low running cost and its quick and easy to install process.

Step by step guide to a residential sewage treatment plant installation

Step 1

The Tricel Novo UK6 Plus arrives on site as per schedule. The homeowner arranged the mini digger on-site and was ready to begin installation of the new treatment plant immediately.

Step 2

A small hole is excavated to fit the dimensions of the Novo UK6 Plus. Concrete backfill got used in this case upon the homeowner’s request, but which wasn’t necessary as the ground conditions were excellent.

Step 3

As per the building control specifications, utility holes and back inlet gully traps got installed in place around the dwelling.

Step 4

Three cubic yards of semi-dry concrete is then used to backfill the hole.

Step 5

The semi-dry concrete is leveled to ensure the tank gets situated in a level position.

Step 6

The angle of the pipe coming into the tank from the dwelling is checked to ensure it connects correctly (at the same level as the invert level on the tank).

Step 7

Installers position the tank into place. Constructed from SMC material, the Tricel Novo UK 6 Plus weighs only 300kg, which is lighter and stronger than plastic alternatives. Installation is a simple process requiring a small digger.

Step 8

Once installed, the level is re-checked to ensure correct positioning.

Step 9

The tank is filled with water, ready to start up. After the electrical connection, the system is immediately operational.

Step 10

The tank is buried in the semi-dry concrete to secure and stabilize its position. Semi-dry concrete is optimal in wet site conditions. Otherwise, 20mm gravel for backfill will suffice.

Step 11

The tank is now covered with topsoil, leaving the access points for servicing and de-building.

Step 12

The installation is complete! Quick, easy & efficient.

The final result

Short lead time, fast delivery and quick installation

In total, it took just three days to complete the whole installation of the residential sewage treatment plant. Including:

  • Creating the percolation area
  • Installation of the tank
  • Installation of all the pipe works around the house
  • The commissioning of the tank.

The project ran smoothly, without any issues, the choice of the tank (Tricel Novo) was also crucial for the ease of installation. The short timeline from the first call, to the installation of the residential sewage treatment plant, was successfully met.

Depawater quickly delivered the clients solution. As the Tricel Novo range is readily available in stock, the customer’s requirements for a speedy and dependable resolution got met easily.
