Asset International's Weholite

The attraction of using large diameter pipes as stormwater attenuation tanks is already being demonstrated in a SuDS-style £4.1M flood alleviation scheme for the North Tyneside village of Shiremore.
Following periods of extreme rainfall in 2005, 150 homes on the estate were affected by flooding. Northumbrian Water made the area a priority for flood alleviation.

Consultant Mott MacDonald presented 14 possible design options to Northumbrian Water with Asset International’s high-density polyethylene (HDPE) pipe, Weholite, deemed the most suitable solution.

The pipes were used to form a 6,000m3 capacity tank system, with 15 parallel pipe runs each measuring 2.1m in diameter and 114m in length.

Rainwater will enter the tank system via a large inlet manifold. Water will then be stored in the tank and gradually released though a smaller outlet manifold into the existing sewer system downstream.

“This is the first time Northumbrian Water has used Weholite in one of our flood alleviation schemes, and we have calculated significant benefits in using this innovative solution, including potential time and cost savings,” says Northumbrian Water project manager Ian Davison.

Work is being carried out by Seymour Civil Engineering.
