Mr. Larry Hamer • <br /> February 13, 1996 <br /> Page 3 <br /> Easy. safe and reliable - the inversion process effortlessly places the Insitutube® against the pipe <br /> wall without friction. The buoyant effect of the water suspends uninverted flexible pipe in a <br /> frictionless media enabling the Insitutube to traverse long distances between openings. The <br /> Insitutube is propelled by the weight of water in the inversion tube. It snakes itself through <br /> misaligned pipe and around bends,pushing groundwater aside. In manually accessible pipe, it can <br /> eliminate the need for workers to enter,thereby doing the same job easier and safer. <br /> Solves stringent time restraints-preparation time is reduced by eliminating street openings, and risk <br /> of damage to other utilities. Insituform can generally be installed and completed in less on-the-job <br /> time than any other method. <br /> 1' The Insituform process offers more convenience to commerce and public -little inconvenience is <br /> caused to the public, commercial business or existing utility operations because excavations are <br /> generally eliminated. Little work space is needed for installation. This alone means less restrictions <br /> on access to property and shops and greater assurance of safety. <br /> Longevity-for normal applications such as gravity sewers, service life of Insitupipe can be expected • <br /> ' to approach fifty years. Service life of Insitupipe is a function of the temperature,pressure, velocity <br /> and chemical and abrasive properties of the materials being carried. <br /> Custom -EnQineered- Insitutubes are custom-engineered to optimize total life performance using <br /> time-proven formulas. These take into account requirements for diameter, length and condition of <br /> pipe, flow rates,temperature, pressure and corrosion of the materials being carried. <br /> We believe the Insituform process would be ideally suited for your pipeline reconstruction project <br /> based on the experience gained in utilizing the process for over 20 million feet of sewers and other <br /> pipelines in various geographical areas of the United States. <br /> Per your request we are pleased to submit the following proposal for the above referenced project: <br /> Item (1) Manhole 432-431-428 <br /> Furnish and install approximately 521 lineal feet of 9 inch diameter Insitupipe with <br /> a minimum nominal wall thickness of 0.282 inches and reinstatement of 7 service <br /> connections. <br /> i <br /> Lump Sum — $ 25,800 <br /> The above price is based upon work to be performed in conjunction with other work <br /> in the area at our convenience. is <br /> :J <br />
