The Water Supply System represents a set of structures and services designed to provide water in adequate quantity and quality to populations. However, the intermittent operation in the Water Distribution Network (RDA) corroborates for the inflow of air in the hydraulic ducts, generating the over-measurement errors. These errors burden water consumers and water supply companies. Therefore, considering the incipience and urgency of practical information to support the problem addressed, this research proposed to contribute to the reduction of micro-measurement errors based on the study of filling speeds in the water distribution network. To achieve this proposal, an experimental protocol was developed based on the characteristics of RDA and a Pilot Network for Water Distribution, adapted according to the experimental conditions outlined. The results obtained indicated measurement errors proportional to the magnitudes of filling speeds of the Pilot Water Distribution Network, being 4,3  0,041, 5,3  0,047 and 17,9  0,018, for speeds of 0,3, 0,6 and 0,9 m.s-1, respectively. However, it was possible to verify that for the situation of intermittent operation in the water supply, the knowledge and control of the filling speed can be a short term alternative to assist in the management of RDA.
