Plastic Leach Drains

Drainwell Leach Drain Module

What Is A Leach Drain?

Plastic leach drains are tube-like structures made of either plastic or concrete and buried underground. Seepage holes in the sides and base assist with seepage of effluent. The leach drain design is governed by a number of factors.

These factors include:

  • the size of the leach drain,
  • amount of liquid waste to be disposed of,
  • type of soil around it,
  • how it is built.

IMPORTANT: Every Novaplas Drainwell Leach Drain module is supplied with a base, or bottom panel. This will increase the life cycle of your system. Other suppliers only supply a base panel in the first module to reduce their costs. Don’t risk buying an inferior system.

The Drainwell Septic Drain Field System has a very effective infiltration surface area. As a result, septic effluent can permeate into the ground at a faster rate than other types of septic leach drains. Drainwell Plastic leach drains are wrapped in geo cloth filter wrap specifically to stop sand filling the leach drain modules. Leach drains are used to dispose of effluent from Septic tanks.

Septic tanks consist of either one or two watertight cylindrical tanks as well as one or two sets of drainage cells which have seepage holes in the sides and base.

Pipe connection is very simple due to a 90mm cut out guide and a 150mm cut out guide in the Drainwell panels. The Drainwell Plastic Septic leech drain will accommodate up to 225mm OD PVC pipe.

Drainwell Plastic Leach Drains are used for new and existing homes and buildings. These leach drains are made for rapid disposal of effluent from septic systems. They can also be used for plastic soakwells. Some examples of applications where leach drains are used include:

  • Residential houses
  • Residential sub-divisions
  • Commercial projects

Turn module over and place final panel onto the top.

Leach Drain Design

Plastic vs Concrete Leach Drains

  • Drainwell Leach Drains are generally more cost effective than concrete leach drains. This is due to factors including the manufacturing process, as well as transport costs.
  • Plastic Leach Drains are light weight and, hence, very easy to install. Concrete leach drains are heavy and generally need a lifting machine during the leach drain installation.
  • Plastic Leach Drains are supplied as an unassembled leach drain kit so that transport costs are minimised.
  • Drainwell leach drains are made from 100% recycled materials, therefore, they are environmentally friendly.
  • Plastic leach drains are chemically inert. As a result, they are not affected by harmful chemicals and will not split or decay.
  • Concrete leach drains have steel reinforcing bars internally. Over time, the steel bars could rust and cause the leach drain to break down and fail.

Drainwell Leach Drains have a rapid assembly and installation procedure so that your project can be completed quickly.
