  Galaxy environment plays an important role in driving the transformation of
galaxies from blue and star-forming to red and quenched. Recent works have
focused on the role of cosmic web filaments in galaxy evolution and have
suggested that stellar mass segregation, quenching of star formation and
gas-stripping may occur within filaments. We study the relationship between
distance to filament and the stellar mass, colour and HI gas content of
galaxies using data from the REsolved Spectroscopy of a Local VolumE (RESOLVE)
survey and Environmental COntext (ECO) catalogue, two overlapping census-style,
volume-complete surveys. We use the Discrete Persistence Structures Extractor
(DisPerSE) to identify cosmic web filaments over the full ECO area. We find
that galaxies close to filaments have higher stellar masses, in agreement with
previous results. Controlling for stellar mass, we find that galaxies also have
redder colours and are more gas poor closer to filaments. When accounting for
group membership and halo mass, we find that these trends in colour and gas
content are dominated by the increasing prevalence of galaxy group environments
close to filaments, particularly for high halo mass and low stellar mass
galaxies. Filaments have an additional small effect on the gas content of
galaxies in low-mass haloes, possibly due to cosmic web stripping.
