Frequently Asked Questions About Invercargill Water Tank Installers
Do I need council consent to install a water tank in Invercargill?
In many cases, consent is not required for smaller, above-ground domestic tanks. However, for larger installations, particularly those connected to plumbing systems or intended for firefighting, you may need approval from the Invercargill City Council. It’s best to consult with your installer or the council directly.
What size water tank should I install for my property?
The ideal size depends on your water usage, roof catchment area, and intended use (e.g., irrigation, household supply, or emergencies). For most residential homes in Invercargill suburbs like Gladstone or Hargest, tanks between 3,000L and 10,000L are common, while rural properties may opt for much larger capacities.
Can rainwater from my tank be used for drinking?
Yes, but it requires appropriate filtration and maintenance. A professionally installed system with proper first-flush diverters, UV filters, and regular cleaning can make rainwater safe for potable use. Always ask your installer about potable water compliance if drinking water is a priority.
How long does installation take for a new water tank in Invercargill?
The timeframe varies based on tank size, site access, and weather, but most standard installations are completed within one to three days. Complex setups, such as those with underground tanks or seismic bracing, may take longer. Your installer will provide a clear timeline during the site assessment.
Are water tanks suitable for Invercargill’s cold and wet climate?
Absolutely. Tanks made from UV-stabilized plastic or corrosion-resistant steel are specifically designed to withstand Southland’s wet winters and high winds. Local water tank installers ensure proper anchoring and drainage solutions to maintain performance year-round, even in extreme weather conditions.
