The watertight manhole system is now covered by Sewers for Adoption and should therefore be accepted by all water authorities. Prior to its inclusion company’s obtained letters from the authorities approving the system for use. These have been superseded by inclusion in SfA.

Such certification is relevant to novel and new products where there is no established experience of its use. As the watertight system is included in SfA and component parts are kitemarked there is no need for BBA certification.

We recommend 1-2 tubs of our lubricant per load of pipes.

There continues to be much confusion and inaccuracy within the construction industry over the carbon footprint of materials, especially concrete. As members of the Concrete Pipeline Systems Association (CPSA), Stanton Bonna are very proud to have participated in the CPSA/Carbon Clear study into the embodied carbon of concrete and plastic pipelines.

This exacting study was conducted to widely recognised international standards and proved that the cradle-to-site greenhouse gas emissions of concrete pipes are generally better than plastic with up to 35% lower CO2e for DN 2100 pipes. It also showed DN 1200 circular precast manhole systems have a 30 to 43% lower carbon footprint compared to DN 1200 traditional manholes, 1250 x 1250mm box based manholes and DN 1050 plastic manholes.
