Ridgidrain Infiltration 1.6<br />
Infiltration Devices<br />
Sustainable Urban Drainage Systems (SUDS) is becoming more prevalent<br />
in <strong>drainage</strong> design [Please refer to <strong>Polypipe</strong> Stormwater management<br />
technical manual]. One key SUDS technique is to encourage surface water<br />
to infiltrate into the ground at source.<br />
The Ridgidrain pipe <strong>system</strong> is available in unperforated, half-perforated<br />
and fully perforated configurations. The perforated and half-perforated<br />
pipes may be used to form several different infiltration devices. With<br />
carrier pipes used to transport surface water to the point of infiltration,<br />
enabling a single integrated <strong>system</strong> to be used, where required.<br />
Typical infiltration structures, using the Ridgidrain <strong>system</strong>, are:<br />
• Ring soakaway<br />
• Horizontal tank soakaway<br />
• Trench soakaway<br />
• Infiltration trench<br />
•<br />
As part of a <strong>drainage</strong> blanket (increasing its storage capacity and<br />
reducing the volume of stone required)<br />
Please refer to <strong>Polypipe</strong> Stormwater Management Technical Manual for<br />
further information of SUDS and infiltration structure design.<br />
