Commercial Kitchen Waste Water
Efficient Drainage Solutions
We install commercial kitchen waste water systems designed for reliability, hygiene and compliance in catering operations.
Built to flow. Built to last.
At JLG Kitchens & Vent Ltd, we understand that effective waste water management is essential for hygiene, safety, and uninterrupted kitchen operations. Poorly designed drainage systems can lead to blockages, odours, downtime, and compliance issues.
Our waste water installations are designed to handle the demands of busy commercial kitchens while supporting long-term reliability.
Waste Water Systems Designed for Commercial Kitchens
​
Commercial kitchens generate high volumes of waste water from dishwash areas, prep sinks, appliances, and floor drainage. We design drainage systems to cope with continuous use while maintaining clean, hygienic conditions.
Our design considerations include:
​
-
Adequate capacity for peak service periods
-
Logical routing of waste water pipework
-
Correct gradients to support effective flow
-
Separation of waste streams where required
-
Access points for cleaning and maintenance
​
This approach helps reduce blockages and keeps kitchens operating smoothly.
Installed for Hygiene, Safety & Compliance
​
Waste water systems in commercial kitchens must support strict hygiene standards and comply with building and environmental requirements. Our installations are completed with attention to durability, cleanability, and safe operation.
​
We focus on:
​
-
Secure, hygienic pipework installation
-
Integration with floor drains and gulley systems
-
Odour control and prevention measures
-
Easy access for inspections and servicing
-
Coordination with water supply and grease management systems
​
These details help kitchens remain compliant and reduce the risk of operational issues.

Frequently Asked Questions
Commercial Kitchen Waste Water
What is commercial kitchen waste water?
Commercial kitchen waste water is used water discharged from sinks, dishwashers, glasswashers, cooking equipment, and specialist appliances. It often contains grease, food particles, and detergents, requiring correctly designed drainage systems to prevent blockages and contamination.
Why is proper waste water design important in commercial kitchens?
Poor drainage can cause blockages, odours, flooding, hygiene risks, and environmental health failures. Correct waste water design ensures smooth flow, compliance, and reliable day-to-day operation.
What regulations apply to commercial kitchen waste water?
Waste water systems must comply with building regulations, water authority requirements, food hygiene standards, and health & safety guidance. Systems must safely remove waste while preventing grease and food debris entering public drains.
Are there special drainage regulations for commercial kitchens?
Yes. Commercial kitchens require grease management, adequate pipe sizing, correct falls, and suitable access for maintenance. Domestic-style drainage is often not sufficient for commercial use.
Can you upgrade existing waste water systems?
Yes. Existing drainage systems can be assessed and upgraded to improve flow, increase capacity, or resolve recurring blockages and compliance issues.
What is a grease trap and why is it needed?
A grease trap captures fats, oils, and grease (FOG) before they enter the drainage system. This prevents blockages, protects pipework, and helps meet local authority and water company requirements.
Do commercial kitchens legally require grease traps?
Many local authorities and water companies require grease management systems in commercial kitchens. Requirements depend on kitchen size, menu, and waste output.
Can you install grease treatment systems like GreasePak?
Yes. Grease treatment chemical dosing systems, such as GreasePak, can be installed to help break down grease within drainage pipework—often used alongside grease traps.
Can pipe sizes be upgraded for waste water?
Yes. Waste pipework can be upgraded to larger diameters where required to improve flow and reduce blockage risk—especially when adding new appliances or increasing output.
Can temporary waste water systems be installed?
Yes. Temporary waste water solutions can be installed for pop-ups, events, refurbishments, or phased works, ensuring safe and compliant drainage during temporary operation.
Can new waste supplies be installed for new appliances?
Yes. New waste connections can be installed to support additional equipment such as dishwashers, glasswashers, coffee machines, and combination ovens.
Does a Rational oven require a waste water connection?
Yes. Combination ovens such as Rational units require a waste water connection for condensate and cleaning cycles. Correct drainage design is essential for safe operation.
What is a tundish?
A tundish is a visible air-gap fitting used in waste systems. It allows waste water to discharge safely while providing a visual indication of flow—commonly used for appliances like ovens and water treatment systems.
Why are tundishes used in commercial kitchens?
Tundishes help prevent backflow contamination and allow quick identification of drainage issues, supporting hygiene and maintenance.
How do I know if my kitchen drainage is adequate?
A site assessment reviews pipe sizes, gradients, grease management, appliance loads, and existing issues to determine whether the system is suitable or needs upgrading.
Can drainage upgrades be carried out in live kitchens?
Yes. Works can often be phased or completed out of hours to minimise disruption while maintaining safety and compliance.
Can you recommend improvements to an existing waste water system?
Yes. Existing installations can be reviewed to identify risks, inefficiencies, and opportunities to improve compliance, flow, and long-term reliability.
How does waste water integrate with other kitchen services?
Waste water systems must coordinate with water supplies, electrical services, appliances, and floor finishes. Proper integration ensures hygiene, safety, and ease of maintenance.
How do I start a commercial kitchen waste water project?
The first step is a site survey. This allows current drainage, appliance requirements, and compliance needs to be assessed before design or upgrades begin.
Do you offer site surveys and quotations?
Yes. A free site survey and quotation is provided to assess your kitchen’s drainage requirements and recommend suitable solutions.
How much do commercial kitchen waste water upgrades cost?
Costs depend on pipework changes, grease management systems, access, and installation complexity. Investing in correct drainage helps avoid costly blockages and downtime.
What areas do you cover for commercial kitchen waste water services?
Commercial kitchen waste water design, installation, and upgrade services are available across London, Essex, and inside and around the M25.
Why choose a specialist for commercial kitchen drainage?
Specialists understand grease management, hygiene regulations, and real kitchen usage. This ensures waste water systems are compliant, efficient, and built to flow—and built to last.
