Which tank for your block?
The 1500L tank, from $949, suits most small dwellings of one to two bedrooms: tiny homes, cabins, granny flats and sheds. It weighs 61 kg, so a standard ute can carry it. The 2500L three-chamber tank, from $1,790 ex GST, suits larger family homes and multi-bedroom rural builds. It weighs 110 kg.
Septic approvals in Byron Shire
Mullumbimby sits in Byron Shire, which enforces a tighter on-site sewage management framework than neighbouring council areas, including ongoing inspection requirements after install. The tank you buy is standard; the paperwork is what differs. Your licensed plumber lodges it, and our council approval guide explains the process.
