How does the overall cost of PE compare in price with other materials?
Underground water pipes are a major long term (50-100 years) investment. In addition to comparing the initial purchase price, the long term maintenance costs and overall life-cycle costs should be carefully evaluated. According to the Federal Highway Administration, utilities spend $36 billion annually on corrosion protection of pipes. Because PE pipe does not corrode and does not leak at the joints, constant repair of aging metal pipes or leaking at the joints with all other pipes is no longer an issue. Initial cost savings are also realized with the opportunity for a trenchless installation. Compared to PVC and ductile iron, PE has the lowest life-cycle costs due to lower installation costs, lower repair rates, less water loss and lower energy costs.
