The Ecovault inground tank range is a fully functional inert polyethylene (PE) structural tank according to the design specification for AS1546.  The inclusions incorporate smooth frictionless internal surfaces; the tank provides safety in handling, with lifting and rolling easily achieved without specialist equipment, tank access with ladder and external grab frame,  standard 600mm x 900mm access opening, site installation with ease of levelling and inter-connections of multiple tanks in series or parallel.  Manhandable, releasable and lockable PE lid with access barriers on lid open and the most convenient multiple pipe and invert level connection configuration.  The Ecov range of tanks also have the ability to apply reflux valve inlet at the base and full drain weapage for infiltration.

The Ecov8 is nominally 8000 litre capacity to the top of the vertical wall.  The external size is 2300mm x 2300mm x 2950mm depth. See installation instructions for pipe connections, tank interconnections for multiple tanks in clusters, backfill and loading conditions.  The tank can be used in high water table applications with appropriate backfill with or without composite concrete balast or using anchor attachments- equally or better than concrete pits.

SG 1.3, buckling factor of 3.9, factor of safety 1.6, 420kg bare tank, hydrostatic uplift anchor ribs, fully sealed to accessway.

The job is normally done as soon as the tank goes in the ground.
