All You Need To Know

  • What’s the difference between a septic tank and a sewage treatment system?

    A septic tank separates solids and allows wastewater to filter into the ground, offering basic treatment. A sewage treatment system processes and treats wastewater further—breaking down waste and producing cleaner outflow. These systems are more environmentally friendly and often required under modern building regulations.

  • Do I need approval to install a sewage treatment system in Darwin?

    Yes. All systems must be approved by your local regulator and meet NT Department of Health guidelines. FastCall Wastewater Solutions handles the entire compliance process, including permit applications, specifications, and scheduling inspections with local authorities.

  • What’s the best sewage treatment system for my property?

    We take into account your property size, usage level, soil type, and drainage needs to recommend the right system. Taylex systems are a popular, reliable choice—but we’ll always recommend the option that best fits your property and local regulations.
