Septic tank upgrade 

First steps to upgrade the sepic tank

To begin with, civil engineer Brendan Slevin, from Brendan Slevin & Associates Chartered Engineers, started working on the planning application for the extension. Before making his wastewater site recommendations he took into consideration the following:

• Site percolation test results.
• Population Equivalent (PE) based on the maximum number of expected teachers and pupils in line with the EPA code of practice for “treatment systems for small communities, business, leisure centres and hotels”.
• Site specifications

Additionally, the site was also compact with no adjacent suitable percolation area. As a consequence, the restricted percolation area had to be located 170m away from the school and wastewater treatment plant.

How we helped

A suitable solution was found by combining the benefits of the Tricel Novo IRL 30 wastewater treatment plant (pumped) and a Sandcel sand polishing filter to suit both the percolation test results and site restrictions whilst meeting the EPA regulations.

The wastewater would flow from the school directly into the wastewater treatment plant. A pump included with the Tricel Novo wastewater treatment plant would push the outlet effluent to the Tricel Sandcel sand polishing filter situated 170m away. The Sandcel 4800 tertiary treatment was chosen to cover the required area of 80 m2.

Once the planning application was successful, a tender was issued and applications were submitted by builders and contractors. It was FVG Construction & Maintenance Company Ltd who became the nominated contractor. With more than 20 years’ experience in building construction, the Galway based company contacted Tricel to discuss requirements, logistics and prices. They were very satisfied with the quality of Tricel cost-effective products and the services offered.
