Dura Composites’ Involvement
The upgrade of Scaynes Hill WTW is part of a five-year programme of work by CMDP – a joint venture between Costain and MWH Treatment which has delivered a range of schemes to maintain and improve Southern Water’s water supply and wastewater treatment works in the eastern half its region (Kent & Sussex). The Scaynes Hill site scored top marks of 45/45 for a recent Considerate Constructors Scheme monitoring visit – a fantastic achievement for the whole team at CMDP.
Dura Composites was selected by to supply a range of d² GRP (Glass Reinforced Polymer) access platforms and chamber covers for the Scaynes Hill WTW. These structures were installed as part of the upgrade works, particularly in the ferric and alkalinity dosing kiosk areas, to facilitate safer and more efficient access to critical operational points. The d² product range represents the next generation of composite solutions for infrastructure, offering several advantages over traditional materials.
GRP: The Ideal Solution for Wastewater Treatment
One of the primary challenges in wastewater treatment infrastructure is the need for materials that can withstand harsh and corrosive environments. Traditional materials, such as steel, are prone to corrosion, leading to increased maintenance costs and reduced lifespan. GRP, on the other hand, exhibits remarkable resistance to corrosion, making it an ideal choice for applications in wastewater treatment facilities.
At Scaynes Hill WTW, the d² GRP access platforms and chamber covers were chosen specifically for their durability and resistance to the corrosive effects of wastewater and chemical exposure. This ensures that the infrastructure remains robust and low-maintenance, reducing the need for frequent repairs and replacements.
Innovations of the d² Product Range
Dura Composites’ d² range is designed, developed, and available exclusively from Dura Composites. The d² GRP products offer significant enhancements over other composite solutions available on the market. A key advantage of the d² range is its efficiency in design, which not only reduces material usage but also results in a lower carbon footprint. In fact, the d² products contain up to 50% less carbon compared to competitor products, making them a more sustainable choice for infrastructure projects.
Additionally, the lightweight nature of d² GRP products makes them easier to handle and install, which can lead to faster project completion times and reduced installation costs. At Scaynes Hill WTW, these benefits were realised as the access platforms and chamber covers were installed efficiently, contributing to the overall cost-effectiveness of the upgrade works.
With a range of successful projects in AMP7, CMDP have also now been successful in securing a framework with Southern Water for Asset Management Period 8. AMP8 will deliver upgrades to water and wastewater assets, including treatment sites, pumping stations and reservoirs, and runs from 2025 to 2030.
