Crowder Consulting provides innovative engineering consultancy services and software solutions to the water industry, specialising in water supply, water distribution and sewer networks

We have positioned ourselves in specialist areas of the water industry, namely in the fields of water supply, water distribution and sewer networks. Our Water Supply & Network Distribution experience covers planning, analysis, design, support and fieldwork. The areas of expertise include leakage/NRW management, customer side services, hydraulic modelling, capital maintenance, network improvement and strategic planning. Our Sewer Networks experience covers planning, analysis, fieldwork surveys, modelling and support. Recent activities comprise surveys and analysis of customer drainage and sewer network ancillaries for regulatory aspects of blockages and pollution.

We have substantial experience with many water utility clients in analysing, mapping, interfacing and integrating very large volumes of corporate systems data. These systems include GIS, customer billing, customer contacts, work management, asset management, water quality, SCADA, telemetry and proprietary logging systems (e.g. Halma, Primayer, Technolog, SEBA, i2O, OSI-PI).

The development of our Netbase water distribution management system is fully integrated with the areas of our consultancy expertise. It is used on consultancy projects and when the system is implemented for clients; our consultancy services have a significant role in these projects. With over 30 years of experience, we provide a range of services to numerous major water service providers, supporting their journey towards Smart Networks. Our core product is Netbase, a Water Network Management System which represents a water operator’s water supply and distribution network, with all associated date series, spatial and time series data.

Netbase provides the current operational and monitored status of the water network and supports a wide range of network management, non-revenue water, operational performance and modelling activities. As a multi-user system, Netbase fully supports multiple users on the local network and through remote access. The system is fully spatial and incorporates the ILOG GIS component enabling spatial analysis and maps, but can also be implemented as non-spatial, using the hierarchy of network areas to navigate around the database.

In addition to Netbase, we are equipped to provide a wide range of services to the water industry, including hydraulic modelling, leakage detection, asset management and planning, data logging, water efficiency initiatives and various data services
