Build a Rainwater Collection System – Throwback Thursday

slimline tanksHere is a series of articles previously published by RainBank, on how to build a rainwater collection system.

The first post in the series focused on how all rainwater collection systems begin at the roof and gutters. Regardless of purpose, i.e. irrigation, supplementation or drinking, debris must be removed before storing rainwater.

The second, third, fourth and fifth posts in the series talked about tank types, tank sizes, how to keep water clean and kinds of filters to consider for your system.

In post six of the how-to build a rainwater collection system series, we cover managing aesthetics so your system fits into your landscaping  design.

If you’re interested in learning about how to install a rainwater collection system, take a look back at these helpful articles.

What Causes Discoloration in My Water?

organic matter in waterTannins in drinking water are caused by natural decaying of organic matter. Leaves or pine needles in the gutters are generally the cause in a rainwater collection system.  A faint yellowing of water generally occurs at .5 parts per million or PPMs with .5 – 2.0 PPMs looking like the color of ginger ale, and 3.0 – 5.0 PPMs would take on the appearance of dark tea. The tannins may cause a yellow color of the water, yellow staining on fixtures, and yellow staining in laundry.

Although aesthetically displeasing, tannins generally pose no real health risk, but may affect the performance of the UV system by not allowing the UV light to penetrate thoroughly through the water column.

Therefore, it is very important to minimize tannins before storage of collected rainwater. Organic matter must be kept from accumulating in gutters, down spouts, and screen baskets. Gutter screens are an effective method of prevention of organics in gutters and down spouts. Both gutter screens and screen baskets should be inspected and cleaned as needed to prevent tannins from occurring. Since the discoloration is in solution, removal can be difficult and expensive. Ozone, ion exchange, and activated carbon can help with removal of tannins to some degree. If you do end up with tannins in your water, it is best to drain the cisterns, rinse and start collection again, however the best solution is diligence in maintenance.

Buried Tanks Offer Zero Visual Impact

Underground Tank Construction2How do you install tanks with no visual impact?

With more than ten years of experience in rainwater collection system designs and tank installs, RainBank loves a good challenge. The issue at hand was to have the storage systems leave no visual impact for a residence with broad, sweeping landscaping.  The solution: buried tanks.

RainBank used a mini excavator to control lowering the tank over the edge and into it’s resting place. With a little landscaping at the top of the rockery, you won’t even see the buried tank.

The rest of the storage for this potable system consists of four – 1,800 gallon buried tanks in the back yard from which an old swimming pool was excavated and the tanks put in its place.

After the tanks were installed, they were back filled and the yard was restored to a nice lawn area with no tanks visible.
