Rain Barrels and Sand Filters for water storage

We don’t have any well or running water on the property but being on the Olympic Peninsula in Washington State, we have a ton of ….  You guessed it. Rain!

We already catch rain off half of the shed roof into one of two 55 gallon barrels we have. It’s connected to a garden hose and then a hose spigot. Used only for washing it works great for us now but I’d like to connect the barrels like the guy in the video did with a PVC manifold. That would give us more pressure and get us through a long summer drought.

I wanna build this:

The master plan is to pump the water in the 2 barrels up to our 650 gallon storage tank on the hill above our property. We’d use a 12 volt utility pump to empty a barrel when the sun is out then let the batteries charge again. If we did it a little everyday we’d have plenty of water in the tank on the hill that could then provide tons of pressure for our cabin. I can imagine some pressure to spray pots off and even take a shower in the summer would be great. Also having some pressure to spray out of a hose would come in handy for fire fighting if we ever had a fire get out of control.

Here is some bad photos of our system now. The rock filter you see stops most of the pine needles, but a screen would be better.

Then someday if we want to drink the water, maybe we’ll make a sand filter. Here’s a great video show you how they work. Towards the end they show it can be backwashed, which you wouldn’t normally do but it’s a good illustration of the concept. Sand filters use microbes to clean the water.

    Pressure filters typically offer lower initial and operating costs than conventional systems, and the package nature of these systems greatly simplifies the design and installation for the engineer and contractor.

    Specifically, pressure filter systems have been developed to focus on common ground water problems like iron, manganese and hardness. For high iron and manganese applications, our pressure filters can be provided with manganese green sand and potassium permanganate feed systems.

    Horizontal pressure filters are especially well suited for the high volume flows required by large municipalities, industries, and power utilities. Our unique multi-cell backwash system offers the economy of horizontal pressure filters, without the need for backwash pumps.

    We supply different types of filter used for industrial and potable water supply. The filter are being used in potable and advance wastewater treatment plant and other industries.

    pressure sand filter consists of a pressure vessel-this could be either vertical or horizontal-fitted with a set of frontal pipe work and valves, graded silica quartz sand supported by layers of graded under bed consisting of pebbles and gravels, a top distributor to distribute the incoming water uniformly throughout the cross section of the filter, and an under drain system to collect filtered water..
