Pressure estimation is crucial for efficient operation and management of water distribution networks (WDNs). However, it often challenged by limited sensor observations. While graph neural (GNNs) have been used to improve hydraulic quality predictions WDNs, their reliance on homogeneous graphs oversimplifies the diverse roles interactions components, resulting in lower performance under dynamic system states. This research introduces a novel heterogeneous network (HGNN) framework, which models control units such as pumps valves distinct nodes while preserving through additional edge types. Experimental results using C-Town benchmark demonstrate that HGNN outperforms GNN terms accuracy, robustness, adaptability, achieving mean absolute percentage error (MAPE) 1.88 % (MAE) 1.70 m 95 masking rate. Additionally, this study shows optimal placement reduces MAE up 15 %, proposed framework achieves high computational efficiency, highlighting its effectiveness WDN analysis management. offers an advanced transferable approach pressure estimation, serving superior alternative traditional evaluation models.
