The HTM-NET observation programme initially benefited from a programme specifically dedicated to the Toulon urban area coastline, "Hydrodynamics and MES Transport: Water Levels and Temperature, HTM-NET" co-financed by the TPM urban community, now Toulon Métropole, and recurrent co-financing since 2013 from the CNRS/INSU, as part of the national "Observation and Experimental Systems for Environmental Research" programme over the long term (SOERE) Littoral - Trait de Côte (PYTHEAS observatory management).
The installation of the sensors was made possible thanks to the support or partnership of various organizations: the Port-Cros National Park, the Syndicat Mixte Ports Toulon Provence (SMPTP), which became a stakeholder in Toulon Métropole, the City of Hyères, the CCI du Var, the Conseil Départemental 13, La Ciotat Shipyards.
