What goes down our stormwater drains ends up in our streams and in the sea. It's important that we work to protect our river and streams, so we can keep Lower Hutt's river and beaches great places to visit, and protect our precious harbour.
Not everything we put down the drain can be cleaned entirely during sewage treatment. A lot of chemicals will just get diluted before they go back into the sea. The less we pour down the drain, the better.
Watch this video to learn what happens when we wash something down our drains, or flush the toilet.
Water saving tips
Check out our extensive tips on how to save water around the home.
Washing your car
The waste water that runs off a car when it's being washed contains heavy metals, detergents, oils and other nasties that your car picks up when it's on the road.
Your waste water shouldn't go straight into the drain. You can block off the stormwater drain with old towels or rags while you do your car wash. Park your car on the lawn instead, and let the grass filter the water - or take your car to a car wash (commercial car washes treat waste water before disposing of it into the sewer system).

Old paint can be taken to Resene or Dulux for recycling, there may be a small charge for non-Resene/Dulux branded products.
Cleaning around the house
- Try using vinegar and baking soda instead of reaching straight for the bleach.
- Avoid harsh detergents or cleaning products. Using gentler cleaning products means you can reuse your grey water on the garden or for yard work
- Use natural detergents, skin and body care products wherever you can or try make your own
- Try to avoid microbeads - little bits of plastic that turn up in beauty products and household cleaners. They don't decompose and they're bad for ocean life
Reduce the amount of water going into storm water drains
- Install a water tank to capture rain from your rooftop. This can also provide additional water supply during droughts. You can buy a water tank from some of our libraries.
- Reduce the amount of area covered with concrete and bitumen (asphalt). Use permeable materials instead that allow water to flow back into the ground.
