Internal Pipe Diameter: 900 mm
Direct access pipe system (DAPS).
Designed to suit most structural and hydraulic specification including installation under roads
The Direct Access Pipe System (DAPS) is the use of Marshalls' sealed pipe system connected together to create a secure solution for the attenuation of water system.
The bespoke offsite solution allows for the layout of the system to be adjusted to suit the volume of water that needs to be stored by adding additional pipework or by using a larger diameter of pipe. The layout of DAPS can also be adjusted to suit the available space on site by interconnecting the pipe runs, which also allows for the flooding of the tank to be simultaneous through all pipe runs as the water enters.
The bespoke DAPS pipe entries can be pre-cored or pre sealed for push-fit connection and end entry units have saddles precast, so chamber rings can be used to meet the required surface levels, with unit having the option to have ladders pre-fitted.
Offering material choice and availability for designers, contractors and installers, the precast DAP system can be used to replace plastic attenuation crates, plastic twin wall pipe and galvanized steel corrugated pipe and requires no special aggregates to be shipped into site to facilitate installation and can be backfilled with the excavated earth at site.
The DAP system does not require membrane wrapping as required on attenuation crate installation and the connection to the DAP system is simple with either new or existing pipework via the pre-cored entry points and can be viewed as an extension to the drainage system.
A minimum cover level of 600 mm at the pipe collar is all that is required for D400 loading which can reduce costs on excavation at site and save on installation times.
