Concern Over Uncertified Drainage Products

3 Sep 2019

The British Precast Drainage Association (BPDA) has discovered that a range of imported precast concrete drainage products such as manhole rings, manhole covers, seating rings, corbels and gully raisers are being placed in the UK market without visible proof of third-party verification or assessment of conformity to relevant European and British standards. As a result, customers can have no confidence in the performance of such products. Third party verification systems are crucial to our industry as they ensure a product’s quality, durability and safe performance in service.  
 
A number of UK industry specifications, such as ‘Sewers for Adoption’, ‘Civil Engineering Specification for the Water Industry’ (CESWI) and different highways’ standards and manuals, require specific precast drainage products to conform to relevant provisions of British Standards such as BS 5911-3. This can only be assured through third-party certification such as BSI’s Kitemark scheme. The industry has a responsibility to demonstrate their products to be safe for their intended use.  
 
Colin Nessfield, Technical Manager of British Precast, advised “Customers, and others in the product supply chain have a responsibility to ensure that the precast drainage products they purchase have the necessary 3rd party assessments and certification, which is the minimum required by the Construction Products Regulation for some of these products. Ignoring these requirements plays into the narrative that elements of the construction industry are still unconcerned about product safety, quality and client satisfaction.”

Precast concrete elements and products manufactured to harmonised European Standards, with an Assessment and Verification of Constancy of Performance (AVCP) level 2+ and legally requiring Declarations of Performance (DoP)  with details of the assessment body and assessment certificates available. Such third-party certification is vital for assuring the safety of products supplied.

The British Precast Drainage Association (BPDA) has now published a blog with further details about the main concerns associated with uncertified precast drainage products. The new blog offers some background on the main European and British standards for precast pipeline products and why third-party certification to BS 5911-3 and appropriate CE Marking documentation is necessary.
