Marley Introduces Stormloc Stormwater Management System

July 20, 2005

Traditional drainage practice is designed to move rainwater as rapidly as possible to a watercourse or river via gravity pipelines or culverts. However, this approach is now increasingly being called into question. Emphasis is now placed on dealing with stormwater run-off at source in a more sustainable manner, thus reducing flood risks downstream and replenishing ground water levels. The new Waterloc system from Marley Plumbing and Drainage is a new design of stormwater storage cell, which combines tried and tested materials and designs in an innovative way.

Waterloc is constructed from 12 columns of honeycomb cell extrusion, manufactured from recyclable polypropylene. Water fills each cell and flows between each of the 12 columns, enabling a rapid dispersion of the stormwater throughout the installation. The hexagonal nature of the extrusion gives it added strength. The grids at the top and base of Waterloc provide additional flow paths and a means to form a monolithic stable structure.

Waterloc connectors are used to join Waterloc cells together. The versatile design of the connector allows it to be connected 'back to back', securing each layer as well as adjacent cells.

Marley is also launching a range of new ancillary items, chief amongst these is the new Inlet Chamber. As with conventional soakaways, concerns have been expressed over the tendency of cell type structures to silt up over time with no means of cleaning or removal of debris. This is dependent on site conditions, however use of the new Inlet chamber provides a number of benefits over conventional installation methods. Access to the soakaway for inspection and cleaning, a housing for an optional filter, access to the incoming pipe connection and improved inflow capacity via a single connection to the drainage system.
