A DENBIGHSHIRE civil engineering firm has completed the second phase of a major water treatment project.

Jones Bros Civil Engineering UK has installed a waste water treatment works after the Ruthin-based company finalised the delivery of a new 840-metre pipeline in Gwynedd on behalf of Welsh Water.

The two-pronged project is the first time Jones Bros has been directly appointed by Welsh Water.

The new pipeline and waste water treatment works will serve Seion, Gwynedd, to meet the demands of population increase in the village.

An updated septic tank was also installed to increase efficiencies.

Phase one of the work ran from June until August, with new outlets and inlets installed for the treatment plant, as well as 15 manholes and a new headwall.

Phase two included the siting of an aerated reed bed, which was the main feature of the waste water treatment works.

This treatment works uses no chemicals, but instead relies on the treatment from the reed bed.

This is one of the first of its kind for Welsh Water in North Wales.

Gemma Roebuck, Jones Bros site agent, said: “The project has been completed on time and handed over to the client.

“On the whole, it has gone really well and the team worked well to overcome any issues and challenges that were present.

“Some landscaping and reinstatement work is now taking place.”

During phase one, no material was taken from site, which reduced vehicle journeys.

The material was re-used or used during the delivery stage of phase two.

The site was excavated to site the installation of the new treatment works, which included a new septic tank, an inlet and final testing chambers, washwater booster and inlet screen.

Jones Bros also carried out full electrical installation, with up to 10 in-house staff as well as subcontractors on site.
