Introduction
Ecological and sustainable rainwater management is an increasingly important subject for
communities, designers and other agencies. Due to the increasing amount of impermeable surfaces
being created by buildings and roads, rainwater falling in urban areas can have great difficulty in
finding its way into the ground or to receiving surface water. This can cause flash flooding, water in
basements and other life threatening situations.
Rainwater harvesting, infiltration and decentralized retention of rainwater (attenuation), are examples
of ecological and sustainable rainwater management. Excess water from rainwater harvesting systems
should be infiltrated into the ground or released in a controlled manner into surface water bodies.
Plastic geocellular systems, sometimes referred to as ‘boxes’, are a preferred solution for temporarily
storing rainwater underground. These boxes can be stacked in layers to form underground storage
reservoirs (e.g. tanks) able to store run-off from intensive rainfall falling over large surface areas. Plastic
boxes have the advantage of being light and easy to install whilst providing a large capacity for storage
relative to their overall volume. Some boxes are strong enough to be installed under roads, parking
areas and other landscape features. They can also be recycled very easily.
This Technical Report contains guidance for installation procedures for thermoplastic infiltration and
attenuation systems outside building structures, which should be completed in conjunction with
product specific installation instructions.
This Technical Report is a guidance document only. It provides a set of general guidelines which gives
best practice for underground installation of thermoplastic infiltration and attenuation systems outside
building structures.
This Technical Report includes recommendations for the reservoir surround and backfilling procedures
but not road base and road sub-base details. Attention is drawn to any national regulations which may
cover these or other aspects of installation.
This Technical Report is intended to be used by local authorities, design engineers, installation
contractors and manufacturers.
In this Technical Report, much of the guidance is expressed as requirements, e.g. by use of “shall” or by
instructions in the imperative. It is strongly recommended that these be followed whenever applicable.
Other guidance is presented for consideration as a matter of judgement in each case, e.g. by use of
“should”.
