overwhelming by 2011. This is when rainwater harvesting became less government-funded and more farmers supported due to an increase in demand without the proper supply. Fast forward to 2010 and now only 20% of harvesting projects have government aid and usually only for technical compliance reasons. Despite this fact, it is still required by the government in many states for any

When collecting rainwater, geomembrane liners can be placed in man-made ponds to encapsulate the harvest and can be used to help control erosion around the containment site. These ponds may not only be lined but also covered with a geomembrane material to prevent further water pollution during storage. They aid in the secure separation of rainwater and groundwater also. Geomembrane bags offer safe storage options for the rainwater as well. Their impermeable barrier makes for unsurpassed containment and derailment of any potential contaminants.

Geobags may be more cost-effective in regards to the price of constructing a reservoir out of pocket and make for easier storage. When referring to the filtration process harvested rainwater may endure, geomembrane fabrics may be manufactured with slightly less strict permeability standards to allow the proper percolation of water, while restraining any larger physical contaminants.

Geomembrane filters have been awarded some of the fastest filtration methods currently available by employing the cleaning and filtration properties of sand and polypropylene materials. Geomembrane filtration products can be manufactured to fit the needs of private sectors as well as construction industries.

After collection and storage, the use of harvested rainwater can be executed through various products geomembranes provide as well.
