The Drainwell module system is very versitile and can be utilised for leech drains (from a septic tank), soakwells (for stormwater management) or as an underground tank.

Features and Benefits

• Strong structural design - can be installed under driveways, carparks and other trafficable areas therefore increasing the use of valuable land.
• Infiltration - large permeable area including sides and ends.
• Detention - Alleviates onsite/downstream flooding.
• Retention - Can be used as a retention tank so that it is easy to collect, store and reuse precious rainwater.
• Larger volumes with fewer modules - projects require fewer modules resulting in less assembly time.
• Chemically inert - the units will not be affected by harmful chemicals, therefore increasing the product life.
• 90mm and 150mm Cut Out Guides for DWV - Allows for simple pipe connection therefore less time is taken for installation.
• UV Stabalised - for increased product life.
• 100% Recycled Polypropolene - Environmentally freindly.
• Modular - The units interlock vertically and position horizontally to create any size and shape required.
• Lightweight - easy to handle. No crane required.
• Flat Pack Form - Easy to transport and save on bulky transport expenses.
• Manufactured in Australia.

Measurements

Each Drainwell Module is made up of a number of large and small plates. Each large plate measures 755mm long x 400mm wide x 20mm high. Each small plate measures 400mm long x 440mm high x 20mm wide. One complete Drainwell module measures 755mm long x 400mm wide x 440mm high.

Capacity

Each module will hold a capacity of 132 litres.

Tanks per m3

7.5 tanks fit into one cubic metre of space.

Types

There are three main types of Drainwell:

• Normal Duty - maximum load of 23.66 t/m2
  These modules feature three small panels (with one internal panel)
   
• Heavy Duty - maximum load of 29.76 t/m2
  These modules feature four small panels (with four internal panel)
   
• Extra Heavy Duty - maximum load of 32.42 t/m2
  These modules feature five small panels (with three internal panel) 

Height of Units

The Drainwell units can come in the following heights:

• 1 Layer (440mm high)
• 2 Layers (860mm high)
• 3 Layers (1280mm high)
• 4 Layers (1700mm high)
• 5 Layers (2120mm high)

	STEP 1 Place 1 x Large Panel onto a firm flat surface. Then insert the required number of Small Panels with the 400mm side into the Large Panel.
	STEP 2 Insert 1 x Large Panel onto the top of the Small Panels.
	STEP 3 Turn module over and insert 1 x Large Panel onto the top.
	STEP 4 Turn module over and insert another Large Panel onto the top.
MODULE STACKING	Follow Steps 1 to 3 above and place the incomplete module on top of the completed module and use a rubber mallet to tap the modules firmly together.
