How Do I Plan my Rain Water Harvesting System?

How Do I Plan my Rain Water Harvesting System?

We would always recommend you speak to an experienced advisor such as RainCatcher’s highly trained staff to assist in choosing a suitable system and we are available in several guises, including live chat, email and telephone, however we have covered a few points below for your reference:

Does the tank have to be underground?

No, not at all.  You should always weigh up the options open to you and design the system to suit your site and needs, this is why we offer a technical help chat and telephone line to give our customers the best service and advice possible to ensure the system choice is appropriate, compliant and user friendly.

Please see a few point to note when making this choice:

  • Situating the tank below ground:
  • Minimal visible equipment in the garden
  • Suitable for smaller gardens or where space is premium.
  • Negligible risk of frost damage to tank

 

  • Situating the tank above ground:
  • Ease of installation and lower installation costs
  • Easier to maintain
  • Risk of freezing in deep frost situations

Do I need a large roof area to provide an adequate supply of water?

No, you very rarely find a lack of roof space being an issue when weighing up yield versus use.

What does a typical rain harvesting system comprise of?

Basically – Tank, filtration and pumping equipment, these are sized according to the project. Once the main component parts have been chosen, optional extras can be added to add value where requested.

When do I need to use a filter?

A filter is recommended in every Rain Water Harvesting project, be it a small garden water butt or a large full system in order to maximise the freshness of the water and water holding period.

What is the best way to distribute water from the storage tank?

You can:

  • Fill a watering can from the butt or tank
  • Use hose or sub terrain porous pipe
  • Use pump – manual hand pump or submersible electric or solar powered pump
