1. A system for reducing infiltrate within a wastewater management system comprising:
a sleeve comprising a flexible sheet having a first end, second end, top, and bottom,
wherein an exterior surface of said flexible sheet at said first end is placed in contact with an interior surface of said flexible sheet at said second end in way that creates an inner cavity having a first opening and second opening,
wherein said exterior surface is configured to secure to said interior surface,
wherein said first opening and said second opening are generally circular in shape,
wherein said exterior surface of said flexible sheet is configured to contact an inner wall of a host pipe,
wherein a lateral porthole of said flexible sheet extends into said inner cavity,
a hydrophilic gasket secured to said exterior surface of said flexible sheet and about said lateral porthole,
wherein said hydrophilic gasket is configured to expand when it absorbs water to create a water barrier between said sleeve and said inner wall of said host pipe, and
a cured in place pipe distributed through said host pipe and said sleeve,
wherein said water barrier reduces an amount of infiltrate freely flowing through a lateral line connection point and into said cured in place pipe.
