200 Nondo Class E Flush Mount Groundwater Well Cover

A Class E Rated Cover for 100mm Wells

The 200 Nondo contains high quality machine cast iron lid and base, with a strong plastic skirt. It is ideal for 100mm monitoring wells and has been tested to exceed load bearing requirements for traffic suitability for Australian Standard AS3996 Class E, which is typically for heavy duty applications.

The large 250mm OD, 200mm ID (164mm between bolt holes) makes the 200 Nondo ideal for remediation wells, or in situations where a ‘GasClam’ sensor is to be installed.

The 200 Nondo well cover is made from SG (spheroidal graphite) cast iron, with a plastic skirt and and is suitable for 100mm monitoring wells. It has been load tested by an independent laboratory to Australian Standard AS3996 Class D & Class E. The traditional looking 2-bolt design has a completely sealed lid with a unique one piece gasket to prevent any surface water ingress. The white lid allows for well ID information to be recorded on the underside.
A large 164mm opening gives plenty of room in the well head for hands & sampling equipment.
Lid removal is made safe and easy with the Nondo Safety Lifter. If you do not have a Nondo Safety Lifter, a small notch in the bottom of the lid allows it to be levered off with a screwdriver.
