*Figure quoted is the difference between Class S (Plastic Flexible Pipe) and Class N (Concrete Rigid Pipe) costs, based on a DN1800 pipe. Potential cost savings are based on normal ground conditions, including granular bedding costs of £15 per tonne and cost of material being taken off-site to landfill at £6 per tonne (figure shown is independent of pipe costs). The bulk density of granular bedding material is assumed to be 2.2 and for excavated material is assumed to be 2.0.
