The present study focuses on current knowledge of the local tap water and sewage systems among the citizens of three western Romanian localities. Only one of the considered localities in this study, namely, Pecica, partially benefits from access to a centralized tap water and sewerage system. The interest in this subject was caused by a procedure initiated by the local authorities to develop and improve the aforementioned infrastructure. The investigation methodology consisted of an online survey. The generated feedback was optimal for determining the general level of residents’ awareness of water and wastewater quality and the means for informing decisions of community interest. Nearly 75% of the interviewed persons declared that they had not been informed about future regional investments. The results indicated the necessity of raising the residents’ awareness about water quality and its importance for health, daily activities, and the environment. Only a few of the interviewees could provide concrete and accurate values for water quality parameters.
