Siltbuster Process Solutions (SPS) has provided a wastewater treatment plan for Welsh Water at its visitor centre while a new plant is built.
The original wastewater treatment works would not have been capable of treating the increased amount of wastewater produced when the refurbished visitor centre in the Llys y Frȃn Country Park Reservoir is completed.
Young Bros (YB), the leading civil engineering contractor, is responsible for demolishing the works and constructing a Rotating Biological Contractor in its place. However, this cannot be built alongside the existing works, due to the lack of space, so YB has tasked SPS with providing a temporary solution to treat the water generated onsite.
SPS has designed and installed a bespoke solution that primarily consisted of two HB20 units, tasked with separating suspended solids and associated organic matter from the waste stream, and an MBBR10, which provides the biological treatment stage. The solution also incorporates Clarity - Siltbuster’s new online, real-time water quality and monitoring system.
This gives YB an accurate overview of how effectively the system is working and provides a text-warning system if something goes wrong.
Jordan Jones, project manager at Young Bros, said: “The great thing about SPS’ work is that it means minimal wastewater has to be tankered offsite while the RBC is being built.
“Tankering can be really expensive, and SPS’ solution has ensured that unplanned costs associated with tankering waste flows has been avoided. As well as that, with the daily lorry movements to and from site that would have been required, we would have risked upsetting locals, which nobody wants.
“Plus, when it comes down to it, SPS’ temporary solution is simply more reliable than tankering for avoiding pollution events– after all, wastewater can still collect and overflow if you’re purely relying on tankering.”
Iain Moir, technical sales engineer at SPS, added: “By gravitating the flow of wastewater to our treatment works, we’ve negated certain issues that can arise when using pumps. The domestic wastewater that our works treat contains rags and plastics, which can compromise how effectively pumps are able to work, removing the risk of pump blockage.”
The visitor centre will include a new outdoor activity zone, as well as a waterside cabin, which will support walkers, cyclists and water sports enthusiasts. A total of £4 million is being spent on the project.
