What is rainwater harvesting system? A rainwater harvesting system is a system that can help us to harvest rainwater and store them or infiltrate them into the ground. What components does a rainwater harvesting system included? There’re generally rainwater catchment area like the building roof top, Hardened impermeable pavement, etc, and filters for interception large particle, intial rainfall removal device (also called initial rainwater flush filter), and automatic rainwater filter, geocellular modular rainwater tank, geotextile and/or membrane .

Two application of this product: 

1. Rainwater Attenuation/retention/detention System.

2. Rainwater Infiltration (Soakaway) System.

Product Advantage:

1.Flexible Design: The size and shape of the underground pool which made of of the modular rainwater tank can be assembled according to the need of the site.

2.High Loading Capacity: the vertical loading capacity of some of some models of rainwater modular tanks can reach 90 tons, the lateral loading capacity can reach 62 tons.

3.High Void Ratio: the void space inside the rainwater tank reaches 95%,we can storage more water in it.

4.Long Service Life: The designd service life of the modular tank is 50 years.

5.Easy Installation: the assembling of the modular tank can be done just by hands, no large machines required.

6.Time Saving: one person can install 75 cubic meters each day.

7.Compact Storage: the modular tank can be piled on pallets, one 40'HC container can hold 294.4 cubic meters.

8.Environmental protection: the modular rainwater tank can be made of 100% recycled pp material,after service life, the pp material can be recycled once again.

9.Money Saving: Compared with the traditional stainless steel and concrete pools, Doctor Rain's Rainwater Tank reduces the time cost, transportation cost and later maintenance cost in many ways.

The modules make up the main body of the underground pool, side plates are only needed for the perimeter of the pool (there's no side plates inside of the pool), and top covers are only needed for the top of the pool. 

The following quantity is for goods loaded in a 40ft HC container

Rainwater tank has the following parts: modules, side plates, top covers, small buckles and big buckles.

One  tank has 2 modules,

One cubic meter has 5 tanks,

One cubic meter has 10 modules,

Modules and side plates are stacked on pallets

Figure on the left is parts quantity on one pallet

Figure on the right is pallets quantity in one container

For example: 128x20 means 20 pallets, each pallets has 128pcs modules.

Qty for modules on big pallet is 192pcs

Qty for modules on small pallet is 128pcs

Qty for side plate on big pallets is 480pcs

Qty for side plate on small pallets is 320pcs

Top covers, small buckles and big buckles are packed in wood case

Qty for top cover in one wood case is 3000pcs

Qty for big buckle in one wood case is 15000pcs

Qty for small buckle in one wood case is 28000pcs

(1). One full container only loaded with modules
128x20+192x2=2944 (modules) ,

20 small pallets, and two big pallets.

(2). One container mixed with modules and side plates
128*19+192*1=2624(modules),
320*2+480*1=1120 (side plates)

(3). One container mixed with module and big buckles.
128*22=2816 (modules),
15000*2=30000 (big buckles)

(4). One container mixed with module and small buckles.

128*22=2816 (modules) 
28000*2=56000 (small buckles)

(5). One container mixed with module and top covers.
128*22=2816 (modules) 
3000*2=6000 (top covers)

If you want to buy one container with all these parts, we suggest the following arrangement:

128*20=2560 (modules)

320*2=640 ( side plates)

3000*1=3000 ( top covers)

15000*0.5=7500 ( big buckles half case)

28000*0.5=14000 (small buckles half case)

With above arrangement, we can put 256m3 of modules into 1 40'HC container, you can also reduce the number of pallets for modules and increase the number of pallets for side pallets if you think you need more of it.
