  • The Nondo Mini monitoring well cover 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 Nondo Mini 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 Nondo Eco 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 Nondo Eco 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.
    • 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 Nondo180 monitoring well 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 FB180 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 Nondo CE180 monitoring well 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:
    • A special shaped skirt to allow a wider concrete support lip and with a larger opening than comparable covers of similar diameter (116mm opening)
    • 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 Nondo200 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 Nondo200 ideal for remediation wells, or in situations where a 'GasClam' sensor is to be installed.
  • A Large Well Cover with Cast Iron Lid The Nondo Maxi 320 monitoring well cover is a large flush-mounted well cover with a cast iron lid and base, and is ideal for 100mm or larger monitoring well installations. The 337mm (OD) diameter cover is secure with 2 bolts requiring an 8mm allen key, and a notch in the bottom of the lid to allow it to be also levered up with a screwdriver. Due to its weight, we have designed a lifter which allows the lid to be removed safely from the base (see video below).
  • A lower cost Class B option

    The Nondo Maxi 320 - Class B monitoring well cover is a large flush-mounted well cover with a cast iron lid and base, and is ideal for 100mm or larger monitoring well installations. The Nondo Maxi 320 - Class B has been tested to exceed load bearing requirements for traffic suitability for Australian Standard AS3996 Class B. Please note that it is not suitable for road traffic. The 337mm (OD) diameter cover is secure with 2 bolts requiring an 8mm allen key, and a notch in the bottom of the lid to allow it to be also levered up with a screwdriver. Due to its weight, we have designed a lifter which allows the lid to be removed safely from the base (see video below).
  • A Large Well Cover with Non-Metallic Lid The Nondo Maxi SMC 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, smc base ring, and a sheet metal skirt. The traditional looking 2-bolt design has a completely sealed lid with a unique one piece gasket to prevent any surface water ingress, and has been tested to exceed load bearing requirements for traffic suitability for Australian Standard AS3996 Class D. 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. Optional add on: Nondo Safety Lifter Use the Nondo Safety Lifter tool to safely remove and reinstall the heavy lid and to avoid crushed fingers.  
  • A lower cost Class B option **Please note this well cover is a Class B well cover that is not suitable for road traffic.** The Nondo Maxi SMC B 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, and has been tested to exceed load bearing requirements for traffic suitability for Australian Standard AS3996 Class B.

  • The TriCap-GAS has a quick connect gas fitting and dust cap installed on the top, enabling gas in the well to be monitored or sampled with a gas instrument or  suitable pump. The TriCapGas can also be locked in place with a padlock or by using a security screw or both for extra security. The TriCap has a partially hollow shaft that intersects a horizontal side hole near the bottom. This allows the well gas to be drawn in through the side hole and out the top. The side hole also serves to hang sampling or monitoring devices off the bottom of the cap while at the same time gas samples can be taken out through the shaft and out the gas quick connect fitting.
  • The WC100GAS has a quick connect gas fitting and dust cap installed on the top, enabling gas in the well to be monitored or sampled with a gas instrument or suitable pump. The WC100Gas can also be locked in place with a padlock or by using a security screw or both for extra security. It has a large wing nut, designed to make it easier to tighten or release the plug. It comes with a ring below so you can hang/attach tubing, skimmers or sleeve samplers in the well.
