Project Overview In operation since 1976, Penybont Wastewater Treatment Works is located near Ogmore beach in the Vale of Glamorgan, and is operated by Dŵr Cymru Welsh Water (DCWW). The site helps treat wastewater services to around 160,000 customers in the Bridgend catchment area. In 2017 DCWW announced a £6m investment to improve wastewater treatment works in Ogmore-by-Sea. Later investigations between 2022 & 2023 would identify further investment was required in the premises infrastructure, and specifically multiple concrete structures, to ensure no cross-contamination of water.

Concrete specialists, Beton Bauen were invited to conduct a series of intrusive and non-intrusive investigations, by the main contractor, IPS, which would evolve into a series of trials. Subsequent findings identified a number of repairs were needed in the water containment areas, as well as a series of fundamental errors by a previous contractor/s that would jeopardise the integrity of the structures. Over the course of 2024 and into 2025, Beton Bauen worked to diagnose the problems, design solutions, and carry out long-term repairs that would keep the works functioning properly and help meet environmental standards...

Project Background

From Beton Bauen surveys in 2023, engineers were able to conclude that some of the water retaining structures had hollow concrete slabs, and the initial concrete repairs highlighted the fact that there was a 'floating' slab, which had effectively de-bonded. The initial survey highlighted the fact that the original building contractor had made the structure too low, causing the de-bonding. Unsuccessfully, this contractor had then put a 70mm concrete topping onto the structures' base, in an attempt to heighten it.

Beton Bauen concrete technicians deployed a PatchPin solution to act as an anchoring system whilst the resin was injected, to ensure that the slab did not lift further, and also to assist in the bonding process.

Once Beton Bauen successfully identified fundamental solutions for repairs and slab re-bonding, from a technical perspective, there were few issues. However, the size, timescale and weather/coastal conditions would all make managing this project somewhat challenging. Delivery of the works required close collaboration, not only with IPS (main contractor) but also with DCWW's engineering and environmental teams, ensuring that all interventions aligned with operational requirements and regulatory standards.

Contracts Manager, Arrthur Dacey explains...

" The water containment units at Penybont Wastewater Treatment Works are working structures. In effect, they have been out of service for two years and undermine efficient operations at the site. Whilst there was pressure to get the water containment repaired as soon as possible, Beton Bauen identified underlying issues with the original build that should be addressed to prevent long term problems"
