Sarawak Water Supply Grid Programme: HT/LT Infrastructure Works

December 1, 2025  |  NPL Engineering

The Sarawak Water Supply Grid Programme represents a critical infrastructure initiative to ensure reliable water supply across Sarawak's stressed areas. NPL Engineering has been instrumental in delivering High Tension (HT) and Low Tension (LT) electrical infrastructure for Package NR1 (Northern Region) of this transformative project.

Project Overview

NPL Engineering was engaged for comprehensive HT/LT electrical works covering multiple work orders across the Northern Region, including:

  • Work Order 1: Elevated/Ground Reservoir construction from Sebauh Junction to Bakun Junction, Bintulu Division
  • Work Order 2: Distribution mains from Ulu Sebauh Elevated Tank to Bintulu Airport Booster Station
  • Work Orders 3, 4 & 6: Additional HT/LT services for stressed areas
  • Solar Power Integration: Renewable energy solutions for reservoir operations

HT/LT Electrical Infrastructure for Water Supply

Water supply infrastructure requires robust electrical systems to ensure:

  • Reliable Power Supply: Continuous operation of pumping stations and treatment facilities
  • High Tension Systems: Efficient power distribution for large-scale operations
  • Low Tension Distribution: Safe and reliable power for control systems and auxiliary equipment
  • Backup Power: Uninterrupted water supply during power outages

Key Electrical Components

Our HT/LT works encompass:

  • High voltage switchgear and transformers
  • Low voltage distribution panels
  • Motor control centers for pumps
  • Earthing and lightning protection systems
  • Solar power integration for remote locations
  • Control and monitoring systems

Solar-Powered Solutions

For remote reservoir locations, NPL Engineering integrated solar power systems to ensure sustainable and reliable operation. This approach:

  • Reduces dependency on grid power
  • Lowers operational costs
  • Ensures continuous operation in remote areas
  • Supports Sarawak's green energy initiatives
