A rainwater well can save a lot of money if you are looking at your water bill at the end of the month. How do you ensure that both your well and the collected water are of excellent quality?  Five tips are given in this article.

  1. Well Size Is Important

Your rainwater well should not be too big or too small. A well that is too large does not overflow often enough. This may reduce the quality of your water. A well which is too small is too often empty if it has not rained for a long time, so you must rely on drinking water again. It is important to find a good balance between a well that is as empty as possible and one that is often filled with enough rainwater. It is recommended to have an expert calculate the ideal size of the well. The main factors that play a role are the number of people who use it, the applications for which you use rainwater, the size and type of your roof and the time that your well is empty.

  1. Don’t Forget Your Filters

Your rainwater installation consists of several filters: the pre-filter, post-filter and possibly an active carbon filter. The pre-filter is usually located at the top of the rainwater well and retains the largest dirt, such as leaves and branches. Sand and silt will end up in your rainwater well anyway.

It is best to check this filter every six months to see if nothing is clogged. It is also good to wash the filter for a while, so that no organic material is deposited on the filter. This prevents your rainwater from going down the drain. The result: your gutters risk to overflow and a safety mechanism sends the water directly to the sewer and no longer to your rainwater well. There are also self-cleaning pre-filters, but doing an occasional check is certainly not an unnecessary luxury.

The post-filter is located between the pump and the various indoor drainage points. This filter stops the last fine dirt particles, so that you do not have sand between your clothes after a machine wash, for example. The activated carbon filter removes any strange odors and colors from your rainwater. You replace this every six month or annually.

  1. Clean Only When Necessary

If your pre-filter does its job well – and you don’t live in a sandy area – a five-year maintenance of your rainwater well is normally enough. Has it been dry for a long time? Lift the lid and see if there is a layer of sludge on the floor.

You don’t have to tackle the walls of the well themselves, especially in the case of a concrete rainwater well. Small active micro-organisms on the concrete ensure a natural purification of the well and of the water present in the well.

  1. Don’t Be Too Gentle

An ordinary garden hose, hand brush, bucket and scoop are sufficient to remove the sludge present in the rainwater well. The pressure washer and cleaning products are best left for what they are. A good scrubbing works is often enough. Simply scoop up the loosened sludge and carry it outside with the bucket. You can use a dirty water pump to pump out the rest of the contaminated water.

  1. Keep An Eye On Your Siphon

Dirty smells are out of the question. Unfortunately, there is a good chance that this will occur. And that has various causes, such as clogged filters, sludge or incorrectly chosen dimensions of your rainwater well. Another important reason is that your siphon has been dry for too long. This mainly occurs during long, dry periods. You can solve this by filling the siphon on the overflow of the well with water. Are the odors not gone yet? Then you can try it with an activated carbon filter, as described above.
