Rainwater harvesting : Ground surface collection.
👉🏼 PDF : https://app.box.com/s/5yow59bp1a1otcdl079b9sdyyphjpzd5 __ A Rainwater Ground Surface Collection system uses the ground to channel runoff water to a storage area. Although rarely done in practice during the acute response phase, any natural or artificial ground surfaces that already exist (and certain types of rapidly installed artificial surfaces such as plastic sheeting) could be useful during the rainy season. Overall, this type of rainwater catchment tends to be more suited to long-term drought mitigation or groundwater recharge.
