Drain Guard and Drain Guard Plus
Drain guards sit inside or over stormwater drains to filter out sediment, debris, hydrocarbons, and contaminants during everyday operations or minor spills. They are ideal for workshops, service stations, construction sites, and anywhere where runoff can carry pollutants toward stormwater systems.
Key Features
• Captures sediment, debris, and hydrocarbons before they enter drains • Helps reduce environmental contamination from runoff • Easy to install, remove, and clean • Suitable for outdoor and wet‑weather conditions • Available in two filter types • Supports HSWA and EPA compliance
For chemical‑resistant sealing during spills, use a Polyurethane Drain Protector
Suitable For
• Workshops and mechanical bays • Service stations and forecourts • Construction and civil works • Transport yards and logistics sites • Industrial and processing areas
How Drain Guards Work
• Placed inside the drain opening • Filters runoff through absorbent and mesh layers • Traps sediment, debris, and hydrocarbons • Allows clean water to pass through • Removed, emptied, or replaced as required
Types Available
Drain Guard (Standard)
Large sediment pocket holds up to 18 kg of silt, sediment, and rubbish
Hydrocarbon filter captures up to 3.5 L of oil and grease
Drain Guard Plus
Large sediment pocket holds up to 18 kg of silt, sediment, and rubbish
Enhanced hydrocarbon filter captures up to 5 L of oil and grease
Ideal for high‑risk areas such as forecourts, mechanical bays, and fuel‑handling zones
Maintenance
• Inspect regularly, especially after rain • Remove trapped debris and sediment • Ensure the guard sits correctly in the drain frame
Compliance Note
If contaminants enter a stormwater drain, you must notify your Regional Council immediately. Drain guards help workplaces meet HSWA and EPA emergency management requirements by reducing the risk of pollutants entering stormwater systems.

⭐ Frequently Asked Questions
• What does a drain guard do It filters sediment, debris, and hydrocarbons from runoff before they enter stormwater drains.
• Are drain guards reusable Yes — most models can be emptied, cleaned, and reused. Some hydrocarbon filters are replaceable.
• Can drain guards be used in wet weather Yes. They are designed for outdoor use and perform well during rainfall.
• Do drain guards stop all liquids No. They filter, not block. For blocking or sealing drains during a spill, use drain mats or polyurethane drain protectors.
• How often should drain guards be checked Check weekly, and after heavy rain or site activity that creates sediment.
• What should I do if a spill enters a drain Notify your Regional Council immediately — this is a legal requirement in NZ.
