GLS Consulting

GLS Consulting provides an extensive specialist service related to the optimal analysis, planning and management of water distribution and sewer and electricity reticulation systems.


The company offers utility clients such as municipalities or bulk service providers a high level of expertise and experience. This is supported by the latest technological developments and the direct involvement of the company’s personnel at all levels. This is most notable in the use of appropriate cutting-edge technology software developed by an in-house team, GLS Software, and an associated company IMQS.

Network digitisation, analysis, design, optimisation and master planning are the basis of the GLS Consulting service in a wide range of disciplines at utilities. A strong emphasis is placed on the importance of a scientifically devised infrastructure master plan to ensure that all communities can be supplied with services that meet acceptable standards. An optimally established master plan is also absolutely crucial in ensuring that the demands of a tight budget are met.

Apart from this specialisation, GLS Consulting also provides expertise and experience in related areas of engineering such as water and electricity demand management, component replacement prioritisation based on risk analysis, the evaluation of component criticality, asset utilisation and performance for the purposes of asset management, water quality modelling, water sensitive urban design processes and fibre optical network design. Other services pertain to revenue enhancement through the identification of metering issues and the long term impact of water and electricity demand reduction on revenue.

The software developed in-house is used by all engineers at GLS and includes the Wadiso®, Sewsan®, Swift, Albion, Edisan, HydroSWMM, PRP and Fonis range of engineering software packages. In addition, the state of the art management viewer software IMQS, from the IMQS Software company, is utilised to produce digital reports in spatial, graphical and tabular format for the utility or municipal infrastructure manager.

GLS Consulting places a high value on the continued professional development of the individuals at GLS who develop programs and systems in the execution of all services to clients.
