Once again, the lighter weight, longer length and inherent flexibility of plastic pipe all add up to lower installation costs at the job-site and a reduced carbon footprint for the system installed. In traditional open trench installations, the lighter weight of plastic pipe means less heavy duty equipment required to lift, manuever and install each section of pipe. Longer pipe lengths and lighter weight means more utility pipe footage can be installed per day, with smaller construction crews and less energy-intensive heavy construction equipment.
