Project Category: Experience in PROPER (Corporate Environmental Performance Rating Program)
Type of Work: Water Audit and Water Resource Conservation
Location: Remen Village, Jenu District, Tuban Regency, East Java
The Water Audit for Fuel Terminal Tuban focuses on assessing water use and water resource management at PT Pertamina Patra Niaga’s fuel receiving, storage, and distribution facility in Tuban Regency, East Java. As a fuel distribution terminal located in a coastal area, Fuel Terminal Tuban operates various facilities and supporting infrastructure that require proper water management. The water audit aims to provide a clear understanding of water demand and consumption patterns, assess water supply and distribution systems, and identify opportunities to improve water efficiency without compromising the terminal’s operational performance and safety.
One of the key aspects of water management at Fuel Terminal Tuban is the varying water demand across office activities, sanitation facilities, supporting operations, and fire protection systems. The presence of a firefighting water pond (PMK) and a drain pond is also an important feature to consider when mapping the facility’s water systems. The assessment may focus on water consumption records, distribution network conditions, the balance between water supply and usage, and the relationship between domestic water consumption and wastewater treatment systems where included in the audit scope. This approach helps identify areas where water use can be improved while ensuring that essential water reserves for facility safety remain available.
Through the water audit, Fuel Terminal Tuban’s management is expected to gain a more measurable foundation for improving water efficiency and developing sustainable water conservation initiatives. The findings can support infrastructure improvement planning, strengthen water consumption monitoring, and help prioritize water-saving programs based on actual facility conditions. Beyond operational and environmental benefits, the audit documentation can also support the company’s environmental performance assessment under Indonesia’s PROPER program, particularly in water conservation and efficient resource utilization.
Define the audit objectives, assessment boundaries, evaluation period, and technical data requirements. This stage may include collecting water consumption records, water supply documentation, distribution network diagrams, facility operational data, and information on existing water efficiency programs.
Identify the terminal’s water supply sources based on available documentation and actual facility conditions. The assessment covers water storage systems, piping networks, and distribution routes to individual usage points, providing a comprehensive understanding of how water flows throughout the facility.
Inspect accessible parts of the water supply and distribution systems, including water storage basins or tanks, pumps, piping networks, control valves, and water usage points. The inspection focuses on assessing system conditions, checking consistency with existing documentation, and identifying areas that require further evaluation.
Identify and map water demand and consumption across office facilities, sanitation areas, maintenance activities, and other supporting utilities included in the audit scope. Water requirements for fire protection systems, including firefighting water reserves (PMK), should be assessed separately from routine consumption to ensure that water efficiency evaluations continue to meet operational safety standards.
Analyze available water consumption records across different monitoring periods to identify usage trends, changes in water demand, and potential irregular consumption. The assessment considers operational activities, the number of facility users, and maintenance work that may affect overall water consumption.
Review the availability, locations, functions, and measurement coverage of water meters used throughout the distribution system. The inspection also evaluates the consistency of water consumption records and identifies where additional measurements may be needed to improve monitoring accuracy.
Develop a water balance based on water supply volumes, consumption across different operational activities, changes in stored water volumes, and outgoing water flows during the assessment period. This analysis aims to evaluate the balance between water supply and consumption, identify unexplained discrepancies, and distinguish actual water consumption from drainage flows and wastewater discharge.
Assess potential water losses across piping networks, connections, valves, storage basins, and other supporting infrastructure. The evaluation involves observing on-site conditions, reviewing water consumption records, and analyzing water balance discrepancies while considering possible measurement errors or unrecorded water usage.
Review the relationship between domestic water consumption, wastewater discharge volumes, and available wastewater treatment systems where included in the agreed scope of work. The assessment may cover mapping wastewater flows to the Wastewater Treatment Plant (WWTP), recording wastewater discharge volumes, and distinguishing wastewater systems from drainage networks to support more accurate water balance calculations.
Identify potential water-saving measures based on the assessment findings, including improved consumption control, distribution system upgrades, facility maintenance, water-saving fixtures, and better water consumption recordkeeping. Water reuse opportunities may also be considered based on facility conditions, water quality requirements, technical feasibility, and applicable environmental regulations.
Develop recommendations to improve water efficiency while considering technical benefits, estimated costs, ease of implementation, and potential impacts on terminal operations. The recommendations may include implementation priorities, monitoring indicators, and evaluation plans to support the gradual implementation of water conservation programs.
Prepare a water audit report summarizing the condition of water supply and consumption systems, inventory findings, consumption analysis, water balance calculations, potential water losses, and conservation recommendations. The documentation can serve as a technical reference for facility management and provide supporting information for environmental performance assessments related to water efficiency under the PROPER program.
The Water Audit for Fuel Terminal Tuban aims to provide a reliable technical foundation for understanding water supply, distribution, consumption, and opportunities to improve water efficiency across the fuel terminal’s facilities. Through a structured assessment, facility management is expected to gain a clearer picture of water demand across different activities, improve the accuracy of consumption records, identify potential water losses, and prioritize improvements to water management systems.
The audit findings are also expected to support operational cost control, water resource conservation planning, and continuous improvements in environmental management. With more measurable water consumption data and documentation, Fuel Terminal Tuban can establish a stronger foundation for monitoring water efficiency initiatives while supporting environmental data requirements for PROPER assessments.
