Why Harvest Rainwater?

Rainwater harvesting provides a reliable, cost-effective, and environmentally friendly way to manage water consumption. Some key benefits include:

  • Reduced reliance on mains water – Lower your water bills and ensure a consistent supply.
  • Emergency preparedness – A stored supply of water can be essential during dry periods or water restrictions.
  • Improved sustainability – Reduce demand on municipal water supplies and conserve precious groundwater.
  • Better for plants and gardens – Rainwater is naturally soft and free from chemicals found in treated tap water.

Your Rainwater Harvesting Options

Choosing the right rainwater harvesting system depends on factors such as available space, water usage, and filtration requirements. Here are some options we offer at Think Water Hawkes Bay:

1. Water Storage Tanks

A crucial component of any rainwater harvesting system is a storage tank. We supply Devan Tanks, a leading New Zealand manufacturer known for durable and high-quality water tanks. Options include:

  • Slimline Tanks – Ideal for urban homes with limited space. These tanks fit neatly against walls or under decks.
  • Round Polyethylene Tanks – A popular option for rural properties, available in various sizes up to 30,000L.
  • Underground Tanks – Perfect for those wanting to conserve space while maintaining significant water storage.

2. Filtration & UV Treatment

Collected rainwater must be properly filtered and treated before use in homes or businesses. We provide a range of UV filtration systems to ensure water is safe for drinking and household use.

  • Pre-Filtration – Removes leaves, dirt, and debris from entering the system.
  • Sediment Filters – Eliminates fine particles and improves water clarity.
  • UV Sterilisation – Ensures bacteria and pathogens are neutralized, making rainwater safe for consumption.

3. Gutter & First Flush Systems

To maximize water quality, we recommend installing:

  • Gutter Guards – Prevents leaves and debris from contaminating your tank.
  • First Flush Diverters – Directs the first flow of rain (which may contain dirt and pollutants) away from the tank, ensuring cleaner water storage.

4. Pumping & Distribution Systems

Whether you need water for household use, irrigation, or livestock, an efficient pump system is essential.

  • Household Pressure Pumps – Provides constant water pressure for homes using rainwater as their primary supply.
  • Irrigation Pumps – Ensures efficient watering of gardens, orchards, or pastures.
  • Solar-Powered Pumps – A sustainable, energy-efficient solution for off-grid properties.
