Network Pressure Data - Lahan, Nepal

The data here was collected as part of a PhD studentship conducting research alongside partners the Beacon Project (a collaboration between Anglian Water and WaterAid). The data consists of network pressure data collected at 12 locations in the water supply network of Lahan, Nepal between 01-12-2023 to 20-01-2025. The pressure logger installations were conducted with the aid of the network operator Nepal Water Supply Corporation (NWSC). The network is fed by two overhead tanks and three satellite boreholes that feed directly into supply. The total length of the piped network is approximately 105km serving 5000 connections. The supply schedule is determined by the manual operation of the borehole pumps and valves at the base of the overhead tanks. Nominally, there are two supply periods a day running from 5 to 8AM and 5 to 8PM.A total of twelve I2O pressure loggers were installed directly onto tappings on the pipes, the locations of the loggers are found in the .csv file. The pressure loggers record at a 15-minute frequency, sending the data to an online portal via the 4G network. Across the data collection period, the loggers 'cut-out' at various times meaning data is missing in the dataset. The pressure data consists of two datasets, the ‘raw’ measured data and ‘calibrated’ data in which five of the loggers were adjusted to account for a zero-ing error.
