GAS MAINS. Undergound gas pipes were traditionally made of iron or steel, sometimes encased in black bitumen or black PVC. During the 1970's new steel pipes were encased in yellow PVC sheathing and subsequently yellow PE pipe came into use.

WATER MAINS. Older water service pipes were laid in lead, copper, galvanised steel or black PE. Since 1980 most water service pipes are now laid in blue PE
