ABSTRACT:
An environmental water resource recycling system of the invention comprises pluralities of drainpipes units, which includes pluralities of drainpipes engaged in pluralities of holder holes formed by coupled frame strips, and sealing lids covering the opening at one end of the drainpipes. An instant water-absorbing sand layer is applied on the soil layer exposed on the ground surface before inserting the lower end of the drainpipes held in the drainpipe unit into the sand layer. Concrete is poured onto the ground to be constructed such that the concrete can integrally cover the drainpipe units. The sealing lids can be removed from the openings on the upper end of the drainpipes after the concrete is solidified, thereby accomplishing a permeable paving and instantly draining the rain on the permeable paving to the sand layer and further to the underground for being recycled as water resource for further utilization.
