Mondo completes over 22,000 Dry Tapping connections each year.

A dry tapping is generally 20mm or 25mm in diameter and includes a connection and service pipe which terminates within each parcel of land (lot) within the estate.

A dry tapping service job includes the installation of the water meter assembly and the meter for both potable and recycled water (where required). It also includes the installation of Meter Locks and Pressure Limiting Valves.


Mondo completes over 1000 wet tapping connections each year.

A “Wet Tapping” represents a new connection that is made into the reticulated water supply main under pressure. A Wet Tapping may be any size from 20mm to 200mm or greater and includes the installation of the meter where applicable.

Mondo completes over 3000 Main-to-Meter connections each year.

A Main to Meter Connection includes tapping the water main, installation of the service pipe from the main to the property boundary and installation of the water meter and data logger, where applicable.  Most importantly, a complete Main-to-Meter Connection ensures the job is completed safely, is compliant and ensures that all stakeholders are actively engaged through the process. 

This is achieved by a team of highly skilled Project Managers who are responsible for assessing the site and scheduling all required field services and materials.

A Main-to-Meter Connection provides Water Authorities with a consistent standard of connection for their customers and provides a higher level of customer service as the connection is completed in its entirety as opposed to multiple stakeholders.

POA are works are typically larger jobs or complex in nature. They include a site-specific quote that factors in all services, permits and requirements to complete the water connection.

Typical inclusions:

  • Site Establishment
  • Traffic & Pedestrian Management
  • Location of Services
  • Excavation of Water Main for new 150mm tapping
  • Boring
  • Supply & Install mm Service to Property
  • Setup new 50mm meter includes stop valves, test point and high hazard backflow and check-valves
  • Setup new 150mm meter includes stop valves, test point and SCVT
  • Reinstate of surface
  • Removal of excess spoil and work-related rubbish
  • Test and backfill on completion

Tee insertion applies to a connection greater than 50mm diameter and where a tapping cannot be achieved under pressure, or due to site conditions, may require a divide valve or a hydrant installation.

Due to the fact that the Water Main is required to be shut off, we will ensure all impacted customers are notified 7 days prior to the work taking place. 

We will cut a section of the main out and insert the Tee piece, or in some cases, plug and seal the service.

Mondo installs 30,000 check meters annually, and specialises in high-rise, high-density environments.

A Check Meter is a water meter that is connected after a main water meter which is used to register water that is used by individual multi-dwelling /occupancy developments on a parcel of land.

Mondo now offers Smoke Testing to water authorities as an effective measure that highlights and captures important data on the condition of their sewer network. 

Many years of experience working within the water industry have provided Mondo with a holistic understanding of the complexities and challenges of managing sewer networks.

We work closely with our partners to provide sewer preventative maintenance to ensure the infrastructure is maintained and enhanced for the health and wellbeing of their customers.

Non-toxic Smoke Testing can locate defects, inflow sources and illegal stormwater cross-connections.  All information provides the water authorities with actionable insights about their network to improve their service to provide a better, more efficient service for their customers and the environment.

Mondo are responsible for the validation of the Magflow meters to ensure the meters are set correctly, the data being recorded is correct and the customers are receiving accurate bills.

We do this by downloading the required data and making any relevant changes to the settings (if required). Whilst on-site, we also make sure the assembly is compliant.

School Water Efficiency Program

The Schools Water Efficiency Program (SWEP) is a Victorian Government initiative funded by the Department of Environment, Land, Water and Planning (DELWP). Over the past eight years, the Water and Gas field services team have successfully installed in excess of 3600 data loggers with 1875 currently active and have attended to nearly 1300 sites across Victoria.

The program provides staff and students with an understanding of their water consumption and efficiencies through a tailored curriculum program via a fun educational online platform. Digitising existing mechanical water meters, Mondo provides the installation and data flow via cellular network design Narrowband Internet of things (NB-IoT). NB-IoT is a low power wide area (LPWA) technology developed to enable a wide range of new IoT devices and services. This is supported by all major mobile equipment and chipset (internal data flow component) and can co-exist with 3G, 4G and 5G mobile networks.

So far more than 8.9 billion litres of water has been saved that would have otherwise cost an additional $28m in water-related charges by early leak detection.

Digital Water Metering

Over the last 18 months the Water and Gas field services team have been working on a high profile digital metering trial for Greater Western Water within Richmond and Docklands in order to better understand the value of the technology for their customers and business. The aim of this trial is to determine whether digital meters can significantly reduce water loss in the network as a result of more timely alerts to both the water retailer and the customer.

The Metropolitan Melbourne water utilities, Greater Western Water, South East Water and Yarra Valley Water, have been working together to explore wide scale digital water meters opportunities under the umbrella of a “Digital Metering Joint Program”. Whilst the utilities are taking a Melbourne-wide approach to the collaboration, each utility is also moving along their own digital transformation. The first stage of Greater Western Water’s digital metering journey involved an End-to-End (E2E) Proof of Concept (POC) trial to assess the feasibility, scalability and customer engagement channels for digital metering roll out.
