SEPTIC TANKS
Dart Septic Tanks are not just functional storage units; they are thoughtfully crafted solutions designed to suit a variety of applications. From residential to commercial, we've got you covered with our diverse range of sizes:
Versatile Options: Whether you need a standard tank from 4500L to 6000L or a dual-chamber variant, we offer the perfect fit. For larger commercial requirements, our 10,000L and 22,500L tanks are readily available.
Preinstalled Convenience: Each of our septic tanks is equipped with a precision-engineered 1mm septic filter, easily accessible via caps atop the tank. Our dual-chamber models provide two separate spaces for filters, ensuring optimal functionality.
Effortless Installation: We understand the importance of a hassle-free experience. Our septic tanks, weighing approximately 4 tons, can be maneuvered on site by digger or seamlessly placed in position by our Hiab trucks.
Quality Assurance: Crafted to meet the stringent NZS3107:1997 standards, Dart Septic Tanks are designed to be buried with up to 600mm fill cover. While our standard tanks handle pedestrian traffic, we also specialize in manufacturing tanks that can endure wheel loads when needed.
At Dart Concrete, we believe in creating solutions that resonate with your needs and seamlessly integrate with your environment. Our septic tanks are more than just products; they are a commitment to quality, innovation, and your satisfaction.
Single Chamber Septics
Single chamber septic systems, ideal for installations in light, free-draining soil, utilize a gravity-fed process for waste management. Once the waste enters the tank, it settles and undergoes filtration through a biofilter, effectively removing all solids. Explore our range of single chamber waste systems – a solution that ensures quality filtration and environmental safety.

Dual Chamber Septics
Dual chamber systems provide superior filtration compared to single chamber units, minimizing bio waste in drainage lines. With two chambers, waste settles first before draining through an initial filter and then settles again in the second tank before being pumped into the drainage field. The second chamber's unique design can also function as a pump chamber, enabling pumping from the tank when your drainage field is situated above the septic system. Explore our efficient dual chamber systems – a versatile solution for effective waste management.

Pump Chambers
Pump chamber systems are crucial in locations where wastewater needs to be elevated, particularly in areas with high water tables. The pump chamber facilitates pumping from the tank when the drainage field is positioned above the septic system. This design aids in keeping the first tank settled, without stirring up the waste, making it an effective solution for wastewater management in challenging terrains. Consider our pump chamber systems for efficient handling of your wastewater needs.
