• The Mini Nondo is our budget bolt-down, flush mounted well cover. It is designed to be used for monitoring wells or for soil vapour installations. With the bolts outside the inner working space, the Mini Nondo gives you maximum internal room for such a small cover. Features:
    • 2 counter-sunk flush bolts to reduce the risk of trip hazards, as there are no protruding bolt heads
    • High strength cast iron in black epoxy
    • White powder coated lid
    • Large internal opening of 124mm (98mm Bolt head clearance)
    • Small 150mm outside diameter
    • Ideal for standard 50mm monitoring wells or soil vapour implants
     
  • A better designed well cover using recycled plastic for sustainability The Eco Nondo 180 well cover is designed with sustainability in mind. The reuse of current resources and the conservation of our future resources are fundamental to all our design concepts where practical. The Eco Nondo 180 is made entirely from recycled plastic and has been tested to meet load bearing requirements for traffic suitability for Australian Standard AS3996 Class D. Features:
    • One piece gasket seals both the lid and around bolt holes heads to prevent surface water ingress, and completely seals the well
    • 2 stainless steel bolts, counter sunk with 8mm hex for secure lid clamp down
    • 180mm diameter OD, large 146mm ID, 122mm between bolt holes
    • High strength recycled plastic (HDPE & Delrin) is resistant to petroleum products
    • Unlike steel, recycled plastic will never rust
    • Lower cost than traditional cast iron covers
    • Light weight only 1.2kg but rated for heavy trucks
    • Load tested to AS3996 Class D traffic rating
    • Ideal for 50mm monitoring wells
    The all recycled plastic Eco180 will never rust leaving your installation work always looking good. No more finger crushing under heavy lids, the Eco180 lid is lightweight with no sharp edges.
  • A medium sized well cover with some big features The 180 Nondo cover contains a high quality machined cast iron lid and base, with a strong plastic skirt. It is ideal for 50mm monitoring wells and has been tested to exceed load bearing requirements for traffic suitability for Australian Standard AS3996 Class D. The small 180mm OD makes it ideal for drillers who typically use a 200mm concrete corer.  
  • A Solution for Legacy Covers The universal FB180mm lid is designed to fit legacy well covers from other manufacturers which are no longer in production. This includes the 'EE' FB180, and other similar covers. Sometimes lids can go missing or get broken on site over the years. Rather than breaking up the concrete to install a new cover, often involving costly traffic management, you can now simply replace the lid. Suitable bolts and an oring is also supplied with the lid. Please note it is not a replacement lid for our Nondo covers.
  • A Class E Rated Cover for Heavy Duty Applications The CE180 Nondo cover is an all cast iron, 'Class E' rated well cover, designed for extra heavy duty applications. It is ideal for 50mm monitoring wells and has been tested to exceed load bearing requirements for traffic suitability for Australian Standard AS3996 Class D & Class E. The small 180mm OD makes it ideal for drillers who typically use a 200mm concrete corer. The CE180 has two new concepts for groundwater monitoring well covers:
    1. A special shaped skirt to allow a wider concrete support lip and with a larger opening than comparable covers of similar diameter (116mm opening)
    2. Bottom sealed bolt holes with removable grub screws for easy bolt hole cleaning if necessary. This ensures ultimate sealing from surface water ingress
     
  • 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.
  • A Large Well Cover with Non-Metallic Lid The Maxi Nondo well cover has a non-metallic lid, making it ideal for wells with instrumentation inside requiring data transmission through the lid, such as a telemetry system. It has an SMC (sheet moulding compound) lid, a cast iron base ring, and a plastic skirt. The traditional looking 2-bolt design has a completely sealed lid with a unique one piece gasket to prevent any surface water ingress. The 337mm diameter cover has an anti-slip dimpled surface on the lid, 2 bolts requiring an 8mm allen key, and a notch in the bottom of the lid to allow it to be levered off with a screwdriver.
  • Extra Large & Traffic Rated With an OD of 350mm the XL Cover is ideal for installations where more room than usual is needed around the well head: for example, remediation work, or where instrumentation needs to be hidden around the top of the well. Features:
    • All cast iron lid and base for strength, with a sheet metal skirt to reduce overall weight
    • Well ID tag on lid
    • Traffic rated design certified by an independent laboratory to meet or exceed H20 and AASHTO M306 roadway loading requirements
    • O-ring sealed
    • Watertight rubber washers around bolts
    • Non-slip surface
    • Compatible with Nondo Safety Lifter (see demonstration video below)
     
  • SD400 - A Large Well Cover for Remediation The SD400 Cover is designed mainly for remediation work where bulky equipment may need to be around the well head. This large cover with a hinged lid offers wide access, with an easy lid opening. It can be ordered with or without a sheet metal skirt fitted.
    • 600mm diameter opening
    • 850mm overall diameter
    • All ductile iron cast construction with sheet metal skirt (500mm long)
    • Hinged lid requires only 1 key to lift up
    • Designed to be cemented into the ground flush
    • Class D400 load rating, (40 ton load)

  • The TriCap-LOG has been specifically designed for use with submersible groundwater level logging devices. Just like the TriCap-GAS, the hollow shaft intersects a horizontal side hole through the shaft near the bottom. An elbow fitting installed in the top enables the well to be vented to the atmosphere. Attach optional tubing to allow the vent port to be raised up above any surface water and prevent it from flowing into the well through the vent. A stainless spring clip is also provided for easy logger attachment.
