Type of Work: Water Audit and Water Resource Conservation
Location: Pranti Village, Sedati District, Sidoarjo Regency, East Java
The Water Audit for PT Pertamina Patra Niaga Aviation Fuel Terminal Juanda focuses on assessing water use and water resource management at the aviation fuel (jet fuel) storage and distribution facility supporting Juanda International Airport in Sidoarjo Regency, East Java. As one of the key facilities supporting aviation fuel supply, Aviation Fuel Terminal (AFT) Juanda operates various infrastructure, including fuel storage tanks, aviation fuel distribution systems, and supporting utility and safety facilities that require efficient resource management. The water audit aims to assess water supply and distribution systems, identify water requirements across different terminal activities, and explore conservation opportunities without compromising the facility’s operational safety or reliability.
One of the key aspects of water management at AFT Juanda is the water demand for fuel storage tank cooling and fire protection systems. The facility has introduced a tank cooling optimization program that uses water from a water pond through an LCPR 65-6.6 Fire Floating Pump. This system allows collected rainwater to serve as an alternative water source, helping reduce dependence on the municipal water supply (PDAM). This initiative is an important aspect to consider in the water audit, particularly when assessing water supply balance, alternative water source utilization, distribution efficiency, and water consumption control during operational activities and safety system testing.
Through the water audit, AFT Juanda’s management is expected to gain a more measurable understanding of water consumption patterns, distribution infrastructure conditions, and opportunities to improve efficiency across different operational activities. The assessment may include water consumption data analysis, water metering system inspections, water balance development, and the identification of water-saving opportunities suited to aviation fuel facilities. The findings are expected to provide a foundation for developing water conservation programs, improving monitoring systems, and strengthening the company’s environmental management documentation to support PROPER assessments, particularly in water efficiency and sustainable resource management.
Collect the technical information needed to establish a reliable foundation for the water audit, including historical water consumption records, water supply documentation, distribution network diagrams, water storage facility information, operational activity data, and environmental management documents. This stage also involves defining the assessment boundaries, evaluation period, and additional data requirements that need to be verified through on-site inspections.
Identify the water supply sources used at AFT Juanda, including municipal water supply (PDAM) and documented alternative water sources. The assessment may cover water storage systems, supply control mechanisms, pumping networks, and water distribution to office facilities, sanitation areas, supporting utilities, and fire protection systems to better understand the relationship between water availability and operational demand.
Inspect the condition of water supply and distribution infrastructure included in the audit scope, such as water storage tanks or reservoirs, pumps, piping networks, control valves, and water usage points. The inspection focuses on assessing installation conditions, checking consistency with technical documentation, and identifying parts of the system that require further evaluation to improve distribution reliability.
Identify and map water consumption across office activities, sanitation facilities, maintenance operations, and utilities supporting terminal operations. The assessment also considers water requirements for storage tank cooling and fire protection systems, allowing routine water consumption to be distinguished from special requirements related to facility safety.
Review the potential and current management of rainwater collected in the water pond as an alternative water source at AFT Juanda. The assessment may cover the origin and volume of incoming water, storage capacity, usage patterns, water losses, and water quality control requirements to ensure that water utilization remains suitable for technical requirements and operational safety standards.
Evaluate water demand and consumption patterns within the fuel storage tank cooling system based on the facility’s existing configuration. The assessment may consider water flow from storage facilities to the spraying or cooling system, required flow rates, operating duration, and opportunities to improve water efficiency without compromising safety functions or the protection of terminal assets.
Review the tank cooling optimization program that uses the LCPR 65-6.6 Fire Floating Pump in the water pond as part of the facility’s existing water management practices. Relevant assessment areas include pumping mechanisms, alternative water source utilization, reduced demand for new water supplies, and water consumption records. The efficiency assessment must also consider emergency water reserve requirements, fire protection system readiness, and facility safety limitations.
Analyze available water consumption records across different monitoring periods to identify usage trends, changes in water demand, and potential irregular consumption. The findings can be used to compare water requirements across operational activities, identify major areas of consumption, and determine which facilities may require efficiency improvements or additional inspections.
Review the availability and functionality of water meters at supply sources, distribution networks, and major water usage points. The inspection may cover recording accuracy, consistency of meter readings, data completeness, and the potential need for additional water meters to improve water consumption monitoring accuracy.
Develop a water balance based on water supply volumes, consumption across different facilities, alternative water source utilization, changes in stored water volumes, and outgoing water flows during the assessment period. The calculations aim to evaluate the balance between incoming and outgoing water, identify unexplained consumption discrepancies, and provide a quantitative foundation for assessing water efficiency programs.
Identify potential water losses across piping networks, connections, valves, water storage facilities, and other usage points. The assessment may involve inspecting installation conditions, reviewing consumption records, and analyzing water balance discrepancies to distinguish possible physical leaks from measurement errors or unrecorded water use.
Review the relationship between water consumption, wastewater flows, and relevant drainage systems where included in the agreed scope of work. The assessment may consider separating uncontaminated rainwater from flows that could contain oil or fuel, including treatment requirements and water quality controls before discharge or reuse. This evaluation aims to ensure that water conservation recommendations do not introduce pollution risks or compromise the safety of aviation fuel facilities.
Identify opportunities to improve water efficiency based on the assessment findings, such as optimizing rainwater utilization, addressing potential leaks, improving consumption control, and upgrading water metering systems. Recommendations are developed by considering technical feasibility, investment requirements, potential water savings, ease of implementation, and possible impacts on terminal operations and safety systems.
Prepare a water audit report summarizing the condition of water supply and distribution systems, water requirements inventory findings, consumption assessments, water balance analysis, potential water losses, and conservation recommendations. The documentation may also include follow-up action plans and monitoring indicators to support ongoing water resource management assessments while providing supporting information for the company’s environmental performance evaluation under the PROPER program.
The Water Audit for Aviation Fuel Terminal Juanda aims to provide a technical foundation for assessing water supply, distribution, consumption, and potential water reuse opportunities across the aviation fuel distribution facility. By considering water requirements for operational activities, storage tank cooling systems, and safety facilities, the assessment is expected to help the company gain a more comprehensive understanding of water consumption patterns while identifying water-saving opportunities that maintain the terminal’s operational reliability.
The audit findings are expected to serve as a reference for developing water conservation programs, improving consumption monitoring accuracy, optimizing alternative water source utilization, and planning improvements that align with the facility’s operational needs. In addition to supporting cost efficiency and responsible resource use, the project can strengthen environmental management documentation and provide technical support for improving the company’s performance under the PROPER program, particularly in sustainable water efficiency and conservation.
