DRAIN PROTECTION:
Prevent spills, wash‑downs, and contaminants from entering stormwater systems
EnviroproNZ supplies drain protection products that provide fast, effective control at the drain — stopping spills before they reach stormwater networks and natural waterways. Designed for NZ industrial, transport, construction, and workshop environments, these solutions support HSWA, EPA, and RMA obligations by preventing hazardous substances from entering stormwater.
What’s in This Category
Nitrile Mats — flexible mats that block and divert spills during an incident.
Drain Guards — sit beneath grates to filter sediment, debris, and hydrocarbons.
Polyurethane Drain Protectors — reusable, chemical‑resistant covers that seal drains during spills or wash‑downs.
Why Drain Protection Matters:
Stormwater drains lead directly to natural waterways — not treatment plants. A single spill entering a drain can result in:
environmental harm, regulatory enforcement, clean‑up costs, reputational damage
Drain protection is a simple, fast, and effective way to stop spills before they spread.
Reporting Spills to Your Regional Council:
If anything other than clean rainwater enters a stormwater drain, you must contact your local Regional Council Pollution Hotline immediately. Under the Resource Management Act (RMA), both the company and the individual responsible can face enforcement action — including infringement fines — if a spill is not reported.
Drain protection products help prevent spills from reaching stormwater systems, but any discharge must still be notified.

⭐ Frequently Asked Questions – Drain Protection
1. What is the best drain protection product for emergency spills?
Drain covers or drain seals are ideal because they create an instant surface seal to stop liquids entering the drain.
2. Can drain protection be reused?
Yes — many drain covers and mats are reusable if cleaned and stored correctly. Some filters are single‑use depending on contamination.
3. Do I need drain protection if I already have spill kits?
Yes. Spill kits absorb and clean spills, but drain protection prevents spread. Both are required for effective spill response.
4. Are drain covers chemical‑resistant?
Most are resistant to oils, fuels, and a wide range of chemicals. Always check the product specifications for compatibility.
5. Do construction sites need drain protection?
Yes — sediment, silt, and hydrocarbons can enter stormwater drains. Drain filters and sediment control products are essential.
6. How do I choose the right size drain cover?
Measure the drain opening and choose a cover that extends at least 100 mm beyond the edges for a proper seal.
7. Does drain protection help with HSWA and EPA compliance?
Yes — preventing contaminants from entering stormwater systems is a key part of environmental compliance in NZ.
