Managing Oily Water Correctly
Oily water is water contaminated with oils, produced by many industrial operations, from washing and process water to bilge and interceptor water. Because it combines water and oils, it needs particular handling so that it meets the applicable discharge and disposal requirements.
This guide explains how oily water is managed and why it needs care. It is general guidance; the discharge and disposal requirements that apply should be confirmed with the relevant authority, and we do not claim particular permits or limits.
Managing oily water correctly protects the environment and supports compliance, with the oils and water separated and handled appropriately rather than discharged untreated.
What Oily Water Is
Oily water is water that has become contaminated with oils, whether free floating, dispersed or emulsified. It arises across many operations and cannot be discharged without handling, since the oils would harm the environment and drainage systems.
Because it combines water and oils, oily water needs handling that separates and manages both. The nature of the contamination, from free oil to stable emulsions, affects how the oily water is treated or handled.
Where Oily Water Arises
Oily water arises wherever water and oils meet, including equipment and vehicle washing, process water, workshop drainage, interceptors and bilge water. Many industrial operations produce some oily water.
Different sources produce different oily water, which is why understanding an operation's streams matters. Sectors such as oil and gas and automotive commonly produce oily water needing correct management.
Why It Needs Management
Oily water needs management because discharging it without handling can harm the environment, contaminate water and drainage systems, and breach the applicable requirements. Proper management separates and handles the oils and water correctly.
Management also supports the operation's responsibilities, providing a correct route for its oily water and documentation of how it was handled. Informal disposal of oily water carries real environmental and compliance risk.
Collecting and Containing Oily Water
Oily water is collected and contained so it can be handled correctly, whether held for treatment, collected for transport, or directed into an appropriate system. Suitable containment prevents the oily water from escaping and contaminating the surroundings.
How it is collected depends on the operation and the oily water, often using interceptors to capture oils and suitable storage or tankers for collection. Proper containment is the first step in managing oily water correctly.
Separation and Handling
Oily water is handled so that the oils and water are separated and each managed correctly, with the oily water handled to meet the applicable discharge and disposal requirements. The handling depends on the nature of the contamination.
Free and dispersed oils are generally easier to separate than stable emulsions, which may need particular treatment. The aim throughout is that the oily water is handled to meet the requirements, confirmed with the relevant authority. We do not claim particular permits or limits.
Recovering Oil and Water Where Possible
Oily water management can sometimes recover both oil and water, where their characteristics allow. Separated oil may be suitable for recovery, and water may be recovered for reuse, supporting sustainability and efficiency.
Recovery depends on the oily water and the treatment available, and is pursued where genuinely possible rather than guaranteed. Where recovery is not possible, the materials are handled and disposed of correctly to meet the requirements.
What Good Management Looks Like
Good oily water management combines suitable collection and containment, separation and handling that meets the applicable requirements, and recovery of oil and water where possible, documented appropriately. It manages the oily water correctly from collection to final handling.
It is also honest, handling the oily water to meet the applicable requirements without claiming particular permits or limits. This keeps oily water management both correct and trustworthy.
- Suitable collection and containment
- Separation of oils and water
- Handling to meet the applicable requirements
- Recovery of oil and water where possible
- Documentation of how it was handled
Managing Oily Water Responsibly
For an operation, managing oily water responsibly means understanding its oily water streams, containing them properly, and handling them to meet the applicable requirements, with recovery where possible and correct disposal where not. Documentation supports its responsibilities throughout.
Approached this way, oily water is managed in a way that protects the environment and supports compliance, which the requirements, confirmed with the relevant authority, define.
