Definitions

  • the present disclosure relates to a modular, scalable system for lining a ditch or other channel for transporting water.
  • Ditches have been commonly used to transport water from one point to another for millennia.
  • earthen ditches have been used to transport irrigation water, potable water, and drainage water. Because they are relatively easy and inexpensive to construct in nearly any kid of terrain, earthen ditches are still commonly used today.
  • the term “ditch” signifies any channel whether dug in the earth and/or completely or partially built above earth level, and includes structures that may be referred to as, for example, drains, culverts, canals, or channels.
  • seepage loss When water is transported through an earthen ditch, significant loss of water can occur in a variety of ways, e.g., seepage, evaporation, and leaks (collectively described herein as “seepage loss”). Depending on a variety of factors, as much as 80-90% of the water entering a ditch may be lost rather than reaching its intended destination. The most significant causes of seepage, losses appear to be related to non-evaporative causes where the water is lost into the surrounding soil, which loss may be accelerated by erosion (particularly for fast moving water), excessive vegetation and/or tree root systems, and rodent burrows. It is known that lining ditches with material that resists seepage dramatically decreases seepage losses.
  • Earthen ditches also require regular cleaning and maintenance to minimize water loss caused by problems such as, for example, ditch wall collapses, erosion, rodent activity, and accumulation of debris or sediment. Maintenance and repair of earthen ditches can be costly because it is labor intensive and can require large equipment.
  • An exemplary embodiment relates to a modular, scalable liquid management system, comprising a plurality of corrugated, connectable ditch liner components, comprising at least one base and at least one arm wherein the ditch liner components are adapted to be cut to change their shape or reduce their length and/or width without compromising their connectability, the ditch liner components are adapted for connection to components of the same type for increasing one or more dimensions of the liquid management system, and the ditch liner components are adapted for side-to-side coupling of components and end-to-end coupling of components; a sealant for placement between adjacent components at or about the point of connection; a plurality of fasteners for coupling ditch liner components together; and at least one anchoring system attachable to one or more ditch-liner components for securing the liquid management system in place wherein the ditch liner components are adapted to be assembled into the liquid management system by connecting a plurality of base components side-to-side and/or end-to-end to form the base of a liquid management system, connecting a plurality
