Septic Tanks

Your septic tank functions like a small-scale wastewater treatment system, breaking down household waste through natural biological processes. Everything that goes down your drains — from toilets, sinks, and showers — ends up in the tank, where solids settle and bacteria help decompose organic matter.
Regular septic tank maintenance and cleaning is essential to prevent blockages, bad odors, and system failure. At CHB Tank Cleaners, we provide professional septic services across Central Hawke’s Bay, helping keep your system efficient and extending its lifespan — while avoiding costly repairs in the future.

Grease traps are essential for preventing grease, fats, and oils from entering your wastewater system and causing costly blockages. Without regular cleaning, grease buildup can lead to clogs, foul odors, and even environmental compliance issues.
At CHB Tank Cleaners, we offer reliable grease trap maintenance services to ensure your system stays clean, functional, and fully compliant. Our scheduled cleaning helps you avoid disruptions and extend the life of your plumbing and drainage systems.

Water Tank Cleaning

Humus buildup in water tanks can significantly impact water quality and system performance. As organic matter decomposes, it releases fine particles and compounds that may clog filters, block pipes, and reduce water pressure. Over time, this can lead to contaminated water, unpleasant odors, and damage to your system. Regular water tank cleaning and maintenance is essential to remove sediment and humus buildup, ensuring safe, clean water and efficient system operation for your household or property.

Essential System Maintenance.

Septic Tanks

How a Septic Tank System Works: All household wastewater flows into the septic tank through an inlet pipe. Inside the tank, solid waste rises to the top and forms a scum layer, while heavier materials settle at the bottom as sludge. As organic matter breaks down, the partially treated effluent water flows through the tank and exits via the outlet pipe. From there, it enters the drain field, where it gradually seeps into the soil, completing the filtration process.

Grease Traps

How a Grease Trap or Settling Tank Works: When wastewater enters the tank through the inlet pipe, grease and fats naturally rise to the surface, while heavier solids sink to the bottom. Inside the tank, baffle walls slow the flow, allowing time for proper separation. This design helps retain the majority of grease, oil, and solids within the chambers, preventing them from reaching the main wastewater system and causing blockages. Regular tank cleaning and maintenance is essential to keep the system working efficiently.

Wash/Sump

How a Grease Trap Works: When grease-laden wastewater enters the grease trap through the inlet pipe, it flows through a series of internal chambers designed to slow the water and encourage separation. During this filtration process, solids settle in the first chamber, while grease and oils rise to the surface. The partially treated water then passes through to the final chamber and exits the tank via the outlet pipe, safely entering the wastewater system.
Regular grease trap cleaning is vital to prevent buildup and ensure smooth operation.
