The eﬀect of pipe ﬁttings (mainly T-pieces) on particle accumulation in drinking water distribution networks were shown in this work. The online measurements of ﬂow and turbidity for cast iron, polyethylene and polyvinyl chloride pipe sections were linked with analysis of pipe geometry. Up to 0.29 kg of the total amount mobilized in T-pieces ranging from DN 100/100–DN 250/ 250. The accumulated amount of particles in ﬁttings was deﬁned as J and introduced into the existing turbidity model PODDS (prediction of discoloration in distribution systems) proposed by Boxall et al. (2001) which describes the erosion of particles leading to discoloration events in drinking water network viz sections of straight pipes. However, this work does not interpret mobilization of particles in pipe ﬁttings which have been considered in this article. T-pieces were the object of this study and depending of the diameter or daily ﬂow velocity, the coeﬃcient J varied from 1.16 to 8.02. The study showed that pipe ﬁttings act as catchment areas for particle accumulation in drinking water networks
