  We present a statistical analysis of the large-scale (up to 2 Mpc)
environment of an homogeneous and complete sample, both in radio and optical
selection, of wide-angle tailed radio galaxies (WATs) in the local Universe
(i.e., with redshifts $z\lesssim$ 0.15). The analysis is carried out using the
parameters obtained from cosmological neighbors within 2 Mpc of the target
source. Results on WATs large-scale environments are then compared with that of
Fanaroff-Riley type I (FR Is) and type II (FR IIs) radio galaxies, listed in
two others homogeneous and complete catalogs, and selected with the same
criterion adopted for the WATs catalog. We obtain indication that at low
redshift WATs inhabit environments with a larger number of galaxies than that
of FR Is and FR IIs. In the explored redshift range, the physical size of the
galaxy group/cluster in which WATs reside appears to be almost constant with
respect to FR Is and FR IIs, being around 1 Mpc. From the distribution of the
concentration parameter, defined as the ratio between the number of
cosmological neighbors lying within 500 kpc and within 1 Mpc, we conclude that
WATs tend to inhabit the central region of the group/cluster in which they
reside, in agreement with the general paradigm that WATs are the cluster BCG.
