Grease Trap Management

Most commercial grease traps require cleaning every 1-3 months, depending on your business size and wastewater volume. High-volume operations like busy restaurants typically need monthly servicing, whilst smaller cafes may only require quarterly cleaning. We assess your specific situation and recommend an optimal schedule that prevents buildup whilst managing costs effectively. Council regulations often specify maximum intervals between services, which we ensure you meet.

All grease trap waste is transported to approved disposal facilities compliant with regional council and trade waste requirements where it undergoes proper treatment. Remaining waste is processed at approved wastewater treatment facilities according to environmental regulations. You receive full documentation including disposal receipts from approved treatment facilities that demonstrate compliance with the Waste Minimisation Act 2008 and satisfy council audit requirements.

Warning signs include slow-draining sinks, unpleasant odours, standing water around the trap, or visible grease accumulation. If your trap is more than 25% full of fats, oils and grease, it requires immediate cleaning to maintain effectiveness. We recommend scheduling regular maintenance before you notice problems, as this prevents emergency situations and ensures consistent compliance.

Yes, TDG Environmental offers 24/7 emergency response across the North Island for urgent grease trap issues. If you experience a blockage or overflow that threatens your business operations, our team can respond quickly to restore functionality. Emergency callouts ensure you minimise downtime and maintain health and safety standards even during unexpected problems.

After each service, we supply a comprehensive service report including the date of cleaning, waste volumes removed, disposal receipts from approved treatment facilities, and before-and-after photographs. This documentation satisfies territorial authority audit requirements and demonstrates your adherence to trade waste bylaws. Our digital record-keeping system ensures you can access service history instantly when needed.

Whilst we don’t prepare consent applications directly, we provide all necessary documentation about your grease trap servicing that supports your application process. Our service reports and maintenance schedules demonstrate your commitment to proper waste management practices. We can also advise on appropriate servicing frequencies that align with council trade waste requirements for your business type.

Pricing depends on your trap size, servicing frequency, site accessibility and waste volumes. Regular maintenance is more cost-effective than emergency services and helps avoid expensive repairs from neglect. We provide transparent quotes before commencing work and can establish fixed-price servicing contracts for predictable budgeting. Contact us for a site assessment and tailored pricing specific to your requirements.

Our specialised equipment handles grease traps of all capacities, from small 200-litre units in cafes to large 10,000+ litre commercial installations in major food processing facilities. We have multiple truck configurations to access difficult locations including basement installations, tight carparks and heritage buildings. Our team assesses site access during initial consultation to ensure we bring appropriate equipment.

Most grease trap servicing can occur whilst your kitchen remains operational, though we recommend scheduling work during quieter periods when possible. Our technicians work efficiently to minimise disruption, and we can coordinate timing to suit your business needs. For some maintenance tasks, we may request temporary suspension of wastewater discharge, which we’ll discuss during scheduling.

Implementing good kitchen practices significantly extends time between services. Install drain strainers to catch food solids, scrape plates before washing, avoid pouring cooking oils down drains, and educate staff about proper disposal methods. We provide practical advice during servicing visits to help optimise your grease management and potentially reduce maintenance frequency whilst maintaining compliance.
