CONSTRUCTION-MANAGEMENT-ORIENTED REVIEW AND PLANNING OF DOMESTIC WATER DISTRIBUTION NETWORKS: A CASE STUDY OF NIDHORI VILLAGE

This 10-page objective-focused research paper reviewed and analysed the existing domestic water distribution system of Nidhori village and integrated construction management principles into water distribution planning. The review found that the network consists of an overhead tank and eight major PVC pipe segments with diameters from 150 mm to 50 mm and ages from 6 to 12 years. The hydraulic analysis showed a strong decline from the source to the tail end: flow decreased from 13.0 L/s to 2.6 L/s, pressure decreased from 3.0 bar to 0.5 bar and supply duration reduced from 3.0 hours to 1.0 hour per day. The calculated domestic demand was 151,500 L/day against an available overhead tank capacity of 150,000 L, indicating a narrow storage margin and a baseline deficit of 1,500 L/day. Leakage levels of about 5-12% and poor pipe condition at P7 and P8 show that service improvement should begin with targeted leakage control and asset renewal. The construction management framework proposed in the paper converts hydraulic deficiencies into work packages, priority ranking, resource planning, quality checks and phased implementation. The most important early actions are P1 leakage repair, P7-P8 condition verification, P8 replacement planning, N6-N8 pressure monitoring and supply-duration balancing. The study concludes that water distribution improvement should not rely only on new construction or storage expansion. A more economical and reliable strategy is to combine existing-system review, demand-service analysis, leakage prioritization and construction-management-based execution.
