The problem

The pumping station at an outfall in Dundee frequently faced the risk of inundation from the tidal waters of the River Tay.

 

The pressure exerted by these tidal waters on an aging penstock presented a pressing concern. Recognizing the urgency of the situation, United Utilities, responsible for servicing the Scottish Water pumping station, reached out to ACE Ltd in search of an effective solution to this looming threat.

WaStop® Inline Check valve

In the early months of 2010, a strategic decision was made to install two DN1200mm WaStop non-return valves at the KGV pumping station outfall in response to the challenges posed by the tidal waters. The WaStop valves emerged as the perfect fit for this specific application for several reasons:

1. **Easy Installation:** The design of the WaStop valves allowed for seamless integration into the pre-existing pipes, eliminating the need for extensive modifications.
 
2. **Marine-Ready Construction:** Crafted from 316 stainless steel, these valves were inherently resistant to corrosion, making them exceptionally suited for marine environments.

3. **Efficient Installation Process:** The installation was expertly handled by USL diving contractors based in Great Yarmouth. Utilizing buoyancy bags, the valves were floated into position, negating the need for scaffolding or draining the surrounding area.

4. **Rapid Deployment:** The entire installation process was completed in a mere two days. Moreover, the valves became operational immediately after installation, ensuring that the pumping station was promptly safeguarded against potential tidal threats.

This swift and efficient solution not only addressed the immediate concerns but also showcased the versatility and effectiveness of the WaStop non-return valves in marine applications.
