In ' addition to being installed without excavation,Insitupipes have been installed where access to only one end is feasible(vertical wells). Also,it is possible to reconstruct only a portion of a pipeline or pipelines with reducers. Easy, safe and reliable-the inversion rocess effortlessly ortlessly places the Insitutube against the pipe wall without friction. The buoyant effect of the water suspends uninverted flexible pipe in a frictionless media enabling the Insitutube to traverse long distances between openings. The Insitutube is propelled by the weight of water in the inversion tube. It snakes itself through misaligned pipe and around-bends,pushing groundwater aside. In manuall ' eliminate the need for workers to enter,thereby doing the same job easier nddssafselble pipe, it can r Solves stringent time restraints-preparation time is reduced by eliminating street openings, and risk of damage to other utilities. Insituform can generally be installed and completed in less on- the-job time than any other method. The Insituform process offers more convenience to commerce and public-little inconvenience is caused to the public, commercial business or existing utility operations because excavations are generally eliminated. Little work space is needed for installation. This alone means less restrictions on access to property and shops and greater assurance of safety. Longevity-for normal applications such as gravity sewers, service life of Insitupipe can be expected to approach My years. Service fife of Insitupipe is a function of the temperature, Pressure,velocity and chemical and abrasive properties of the materials being carried. ' Custom-Engineered-Insitutubes are custom-engineered to optimize total life performance using time-proven formulas. These take into account requirements for diameter,length and condition of pipe,flow rates,temperature, pressure and corrosion of the materials being carried. ' We believe the Insituform process would be ideally suited for your pipeline reconstruction based on the experience gained in utilizing the chon protect �g process for over 30 million feet of sewers and other ' pipelines throughout the world. Per your request we are pleased to submit the following proposal for the above referenced project: i 1 1
