Bypass Fuel and Oil Separators

Bypass fuel and oil separators ensure that harmful hydrocarbons, such as oil and fuel, are efficiently filtered from water runoff before they enter the drainage system. 

At Cotterill Civils, we provide a comprehensive range of bypass fuel and oil separators designed to meet the highest environmental standards.

What are Bypass Fuel and Oil Separators?

A bypass fuel or oil separator is a system engineered to treat rainwater runoff from hard surfaces, such as roads and car parks, where there's a lower risk of regular oil contamination. 

Unlike full retention systems, bypass separators only treat the first flush of water, which is where the highest concentration of pollutants typically occurs. These systems divert excess water during heavy rainfall, maintaining optimal performance without overwhelming the filtration process. 

Key uses include:

●     Fuel separators: Designed to remove fuel from stormwater, preventing contamination of watercourses.

●     Oil separators: Capture oil and other hydrocarbons, reducing pollution and helping meet environmental regulations.

Types of Bypass Separators

We offer a variety of bypass fuel and oil separators to suit different applications, including:

1. Class 1 Bypass Separators

These are designed to remove light liquids, such as oil and fuel, from water to meet stringent environmental standards. 

Ideal for areas where a low level of oil contamination is anticipated, Class 1 separators come with a coalescence filter that ensures efficient separation and are typically used in high-risk areas like forecourts and industrial sites. 

2. Class 2 Bypass Separators

Class 2 separators are suitable for applications where environmental risks are lower. These units provide a cost-effective solution for sites like car parks, where there is minimal oil contamination risk. 

Although less stringent than Class 1, they still offer excellent protection against oil and fuel entering watercourses.

Benefits of Bypass Fuel and Oil Separators

●     Environmental protection: Prevents harmful hydrocarbons from contaminating rivers and lakes, supporting compliance with environmental regulations.

●     Cost-effective: Bypass separators are more affordable than full retention systems, making them ideal for lower-risk sites.

●     Efficient design: They treat the most contaminated portion of runoff, optimising filtration without compromising water flow during high rainfall.

Frequently Asked Questions

What is the purpose of a bypass fuel and oil separator? 

A bypass fuel and oil separator is designed to treat water runoff from hard surfaces, filtering out harmful hydrocarbons like oil and fuel. 

These systems are particularly useful in areas with a lower risk of heavy contamination, such as car parks and roads. By capturing and filtering out pollutants, bypass separators help protect the environment and prevent contaminants from entering drainage systems. 

For more information on selecting the right separator for your site, contact Cotterill Civils today. 

How does a bypass separator differ from a full retention separator? 

Bypass separators only treat the initial runoff from rainfall, which typically contains the highest concentration of contaminants. 

In contrast, full retention separators treat all the water runoff. Bypass separators are more cost-effective for sites where there is a low risk of oil contamination, making them ideal for car parks and light industrial areas. 

If you're unsure which system suits your needs, get in touch with Cotterill Civils for expert advice and recommendations. 

Where should I install a bypass fuel and oil separator? 

Bypass fuel and oil separators are ideal for installation in areas where oil contamination is less frequent, such as car parks, minor roads, and hardstanding areas. 

These systems help to capture hydrocarbons in the most polluted water, ensuring that you comply with environmental regulations. 

For guidance on installation and selecting the best separator for your project, reach out to the team at Cotterill Civils today. 

What are the maintenance requirements for bypass fuel and oil separators? 

Regular maintenance is crucial to ensure that bypass fuel and oil separators function efficiently. 

This typically involves inspecting and cleaning the system to remove any accumulated hydrocarbons and debris. Periodic checks will help to maintain the system’s performance and extend its lifespan. 

For detailed advice on maintaining your separator, contact Cotterill Civils' expert team, who can offer support and maintenance solutions tailored to your requirements.
