What they think of the EMI application and our expertise
What our customers say
1 year ago we had major problems with our boreholes, with the columns all being pierced. We had to carry out an audit quickly to assess the impact on pumping capacity. Our service delegate, Saur, suggested a partnership with ImaGeau to try and understand what was happening to our boreholes.
So we asked ImaGeau to carry out pumping tests and camera inspections, and then give us some recommendations. The main aim was to improve our pumping capacity, because when we took over, we had around 49 cubic metres per day authorised, and we wanted to know the real capacity at full capacity.
There were several benefits to this study. Firstly, we realised that our boreholes were in a mediocre state. So it enabled us to carry out essential work relatively quickly. We replaced all the columns with stainless steel equipment, which increased our pumping capacity. As a result, our pumping capacity has increased to 62 cubic metres per day.

“Calculations save time”.
Among our resources, 5 boreholes and 1 piezometer are monitored with the EMI application as part of a hydrogeological study. The water tables tapped by these structures are very different: an unconfined alluvial water table and a semi-captive to captive water table in sub-molassic sands. We only use them occasionally.
The resource is the starting point for the entire water network. It is essential to monitor it and understand the risks. EMI is an effective management tool that all the parties involved need to grasp: the operator for the day-to-day management of facilities and resources (taking into account drawdowns and the transition from one facility to another) and the syndicate for medium- and long-term planning of production assets and changes in resources. The calculations performed save time that can be devoted to human interpretation (the local hydrogeologist working for the syndicate).

On the Syndicat’s territory, the drought framework decree drawn up by the DDTM has defined reference piezometric levels. It is essential that these piezometric levels are taken into account in the application.
In terms of the application’s ergonomics, the graphical representation is clear and the display of the different years is an asset (clear and concise display). In 2020, as the area did not experience any marked drought, the historical meteorological data was not used.

All the services were honoured. The work was always carried out with care by ImaGeau’s technicians. Throughout the study, they were able to adapt to the technical and political context of the SRB. The reports are of a high quality. We really enjoyed working with them for 4 years. The hydrogeological expertise is significant. We will not hesitate to entrust them with new assignments in the future.
We highly recommend ImaGeau.

Crau mixed groundwater management syndicate
The Syndicat Mixte de Gestion de la Nappe Phréatique de la Crau is the manager of a body of coastal groundwater, the subject of major water withdrawals that are strategic for the area. The downstream part of the aquifer contains a body of salt water that comes into contact with the freshwater aquifer, forming a “salt-water interface”. To understand the hydrogeological mechanisms that control changes in the equilibrium between fresh and salt water, and consequently the vulnerability of drinking water catchments, we need to rely on an observation network that is both geographically and metrologically appropriate.
To this end, SYMCRAU has worked with ImaGeau to equip a sentinel monitoring piezometer with the SMD system. The instrumentation was installed by ImaGeau teams in October 2019, and the data can be accessed in real time via the EMI Exploitation platform. By regularly displaying the data and setting alert thresholds, we can accurately assess the state of salinisation of the aquifer in all its dimensions. The ultimate aim is to adapt, if necessary, the management measures and/or operating conditions of a wellfield.

“The study enabled us to identify areas for improvement in our monitoring”.
“The study has enabled us to identify areas for improvement in our monitoring”.
Every year, we carry out an assessment of the hydrogeological monitoring of the Lez spring, and for the period from 2019 to 2021, we have chosen ImaGeau as the consultancy and service provider to carry out this work.
Montpellier Méditerranée Métropole already has tools for monitoring changes in the water level at the source of the Lez. With the EMI Vigilance tool, we have extended the monitoring to all the piezometric points in the catchment area,
and we have also collected data that is monitored by operators other than the metropolitan authority.
The study has enabled us to identify areas for improvement in our monitoring, in particular the need to recalibrate our probes to ensure that we have properly consolidated levels. It has also given us a proposal for a quality monitoring network to monitor the entire catchment area.
This project will enable us to produce situation reports on the state of the karstic resource of the Lez in a much more precise and comprehensive way than has been possible up to now, and to be able to disseminate this information in a very educational way, both internally within the various departments of the city and to all our partners on the departmental drought committee.

“We appreciated ImaGeau’s ability to take into account our remarks and comments throughout the tool development process”.
The work carried out by ImaGeau for the SDEAU50 consisted in providing an IT tool dedicated to the management of hydrogeological, hydrological and meteorological data and water production facilities. In addition to complying with the proposed specifications, which required ImaGeau to adapt its tool considerably to meet them, it was the ability to take account of our remarks and comments throughout the development process to adapt the tool to our needs that was appreciated by our departments. There’s real added value in the fact that the ImaGeau team is made up of both IT specialists and hydrogeologists, which means that the business software meets our needs very well as a water management authority.

“Customer service is very flexible in adjusting to our specific needs”.
As an analyst at Axpo, I’m very satisfied with the services provided by ImaGeau, both in terms of the quality of the data supplied and the customer service, which shows great flexibility in adjusting to our specific needs. ImaGeau provides us with quick, easy and centralised access to different types of hydrological data, bringing invaluable information to our analysis of the electricity markets in France.

“Our ability to react means we can work with ImaGeau with complete confidence”.
The implementation and development of the EMI tools went very smoothly. This was made possible by constant monitoring and exchange. Their ability to react to our requests means that we can work with ImaGeau with complete confidence.
