East Yorkshire Housing development opts for FP McCann’s modular concrete attenuation tank

Concrete precast drainage and SuDS products manufacturer FP McCann has supplied and installed an 840m3 precast panel tank to offer stormwater storage and attenuation for Beal Homes’ Pilgrim Walk residential development in Hessle, East Yorkshire.

FP McCann’s StormTank™ is one of a range multi-purpose precast concrete tank solutions by FP McCann. It can be designed and installed up to 6 metres high and with overall dimensions to meet the project’s brief. StormTank™ is now accepted by a number of Water companies, including Yorkshire Water, and can be adopted under Section 104 of the Water Industry Act (1991) adoption process as described in Sewers for Adoption.

With a water storage capacity of around 837 cubes metres, the 10-sided Hessle StormTank™ is one of the largest ever to be installed in the last few months. It was mainly designed to release surface stormwater at a controlled rate into the conventional drainage system, reducing any risk of downstream flooding or sewer overflow. With a 100 or 120 years intended working life and 10 man access

FP McCann, in collaboration with design engineers Alan Wood & Partners, carried out a value engineering exercise to help specify the precast concrete panel tank system into the designated footprint with a focus on simplicity of construction and increased performance efficiencies over competing systems. Guy Jewitt, Beal Homes Technical Director, comment on StormTank™ sums up why precast tank system continue to offer the most preferrable and reliable SuDS attenuation choice: "With final adoption under the Yorkshire Water S104 approval process, we had to take into consideration a number of factors on tank design. Robustness and long-life together with low maintenance performance were key to our choice of attenuation tank” he noted, "On future projects, we will certainly consider similar FP McCann supply and install precast concrete StormTank™ panel tanks systems."
