Reuse Infiltration System
Underground applied with water permeable well, water permeable drain,
water permeable rock, water permeable drain cover, main hole etc
compose to become rainfall reuse Infiltration system. Truly collect
rainfall, permeable into underground, fill in underground water.
Please see diagram below.

Collect and reuse rainfall theory:
1. When rainfall flow along horizontal plane of tar road surface
to both sides of road, via Sand-based Water Permeable Drain Cover
 quickly permeable to Sand-based Water Permeable Drain ; when
rainfall flow into water permeable drain , at the same time,
water is permeable downward. If rainfall volume is over the water
permeable speed, it will overflow to water permeable well  via
overflow pipe ; If meet very heavy rainfall, water in volume
is faster than water permeable speed in water permeable well ,
water will overflow via overflow pipe  to existing drainage system.
2. In order to prevent sudden moment serious rainstorm floods,
that the rainfall volumes over the water permeable speed of water
permeable drain cover , using existing drain hole for overflow
use, drain away extra rainwater, to eliminate flooding.
3. For walking road, water permeable brick with high pavement water
permeable rate, can realize rainfall infiltrate.
Rainfalls Reuse Infiltrate System Features:
The most notable feature is the pavement water permeable road surface
on both vehicle roads. A lower cost solution to collect rainwater
on vehicle road surface, the specific features as follows:
1. Good water permeable, prevent flood
Product applied is Sand-based Water Permeable Series Products, combine
to water permeable system, has unique water permeable theory, destroy
water surface tension to realize water permeable. Special material
make water when contact at brick surface, water surface tension
can quickly destroy and decrease, increase water permeable ability,
realize high efficiency water permeable. Normally water permeable
rate is 6.8 x 10-2cm/s, which is 6.8 times more than standard value.
It can be customize to become 20 x 10-2cm/s.
According to above water permeable speed, Rainfalls Reuse Infiltrate
System can drain up to 6000mm/24h, this infiltrate system can stand
50years 1 time, serious strong rainstorm (rainfall volume reach
150mm/24h). It can drain water on tar road surface which area is
40 times more than sand-based water permeable road surface. Drain
ability is advantage.
2. Long water permeable effective period
System use sand-based water permeable brick’s theory to product
water permeable drain cover, well and etc. Surface is compact, gap
is smaller than dust diameter, therefore difficult to block by dust,
and has long period of water permeable ability; so far 3 years installed
pavement sand-based water permeable brick sill has very good water
3. Strong load ability
This system is using natural Aeolian sand as material, via binding
(one type of organic material), produce after compress. Because
has strong toughness (resist pressure can reach 88.5Mpa), resist
bending can reach 83.85kN (13 times more than standard value), therefore
has very good toughness. In addition to drain cover thickness and
binder, increase binder, etc method, to increase toughness. Hence,
the combination of water permeable drain and drain cover has very
high load ability. For the diagram below, a truck has 30 ton load
is park on above the drain cover, that drain cover is good in condition.
4. Easy to install
According to customer needs, can be customize, to ease installation;
especially water permeable road surface installation (compare to
tar road surface), install water permeable drain, drain cover is
This infiltrate system is not only has the unique water permeable
function, effectively let rainwater permeable to the bottom, fill
in underground water, and also can solve heavy rainstorm floods.
In addition, pavement with sand-based water permeable road surface
(compare to tar road surface) is only partial pavement, can largely
decrease pavement cost, is good economic.
