This document discusses pond lining using plastic films to efficiently collect and store rainwater. Pond lining helps overcome problems of water scarcity by allowing for effective rainwater collection and storage. Plastic films are lightweight, flexible, tough, and hydrophobic, allowing for zero water seepage. Pond lining services include site selection, excavation, soil preparation, film selection and installation, joint sealing, and security fencing. Proper installation prevents water leakage and damage to the lining.

1. Pond Lining

2. Introduction Green revolution in India has achieved a phenomenal growth in Agriculture production in the last few decades. Yet it’s dependence on seasonal vagaries has long been impediment to all round steady growth, leading to expensive relief operations for drought and floods. In some of the areas even the limited water available through scanty precipitation is lost due to inadequate collection and storage facilities. This results in acute water shortage both for drinking as well as for irrigation purposes. Modern methods of water storage and usage must therefore be adopted to overcome the problems. Lining of rainwater harvesting ponds is one of such measure, which could help in effective collection and storage of the rainwater. In the last few decades use of plastic films for Pond lining across the Globe is increasing. The advantages offered by them such as light in weight, flexibility, toughness, and hydrophobic nature and above all are 0% sippages of water. Hence lining of Plastic Film offers both economy and efficiency. www.essenpoly.com

3. ESSENcan make this technology available in your desired area. The speedy adoption of this technology would go a long way in overcoming the problem of water scarcity by efficient storage. These systems can prove to be more beneficial in the irrigation of horticulture plants in peak periods resulting in more yield. www.essenpoly.com

20. Pond Lining Procedure www.essenpoly.com

21. The Pond is excavated according to the required dimensions based on the quantity of water needed to be stored. Length x Breadth x Depth www.essenpoly.com

23. The recommended slide slope in case of soil cover 3.5:1= {Horizontal: Vertical} and 1.5:1 in case of brick lining. www.essenpoly.com

25. The stability and inclination of slopes and all sharp edged objects are removed www.essenpoly.com

27. Final cleaning of the sub grade soil and surface dressing. If the surface is not done well may lead to damage while handling or laying of the film. If not this will cause leakages. www.essenpoly.com

29. Laying Of GI Mesh To Prevent the entry of aquatic creatures like crabs, frogs, etc www.essenpoly.com

31. Joining of available rolls to required size by fusion welding. Uniform sealing of joints is essential to avoid seepage of water through joints. High degree of accuracy is required for joining of the film. www.essenpoly.com

33. Laying of LDPE Film across the pond to conform to the shape of the surface www.essenpoly.com

35. A small trench of 150mm x 150mm is dug around the external periphery of the pond to anchor the film. Excavated material is placed to prevent the entrance of air so that its position does not change. www.essenpoly.com

37. The wrinkles on the surface are removed by the blowing of air. www.essenpoly.com

39. All the joints are checked before filling the pond with water. Special tape is applied for the overlapping area. www.essenpoly.com

41. After the final inspection of all joints the storage of water is started. www.essenpoly.com

43. Provision is made to drain out the excess water in case of overflow. www.essenpoly.com

45. Space For Pumping Foundation www.essenpoly.com

47. Water Storage

48. Safety parameters are considered by providing chain link fencing around the periphery of the pond. www.essenpoly.com

51. Water Storage Tank

52. To avoid prolonged exposure of pond lining film to the sun after laying and joining of the film at least 300mm thick soil cover should be placed over the bottom. www.essenpoly.com

54. In order to avoid prolonged exposure of pond lining film to the sun and to prevent it from deterioration so as to increase the life of the pond lining film single brick lining should be provided on the slopes of the pond www.essenpoly.com

56. In the case of brick lining a toe wall of size 300mmx300mm is essential all around the bottom periphery of the pond to support the brick lining www.essenpoly.com
