Are you considering Building a dam on your property / creek

<< < (2/2)

Mary B:
One of the hydro guys will be able to answer that better than me... a 2 meter drop doesn't generate much... friends was uphill from his house so he had a 5 meter drop.... I know there is a website with a calculator to tell you how much power etc... Friend drains his in fall and swings it up out of the water channel because the channel freezes over on top. Being a water wheel he needs open water. We didn't calculate anything, seat of the pants redneck engineering. His little pond is spring fed so he gets no flood runoff into it. He pulls his drinking water from that spring! It is pure, cold and tasty! I have done a couple beer brews for him using it and it turns out some really tasty beer.

as long as you have enough flow 2m will work

Sorry for taking so long to respond and thanks for the replies, I do not get online daily. I found some great information in the format of PHD thesis papers out of the UK that had several spread sheets to figure power calculations, and the turbine design based on flow and drop. I bought a transit level and I need to get a true calculation on the drop. We only have about 400 feet of creek on our property to get drop. Except during August and September we have quite a bit of flow to fill an 8-10 inch pipe, just not a lot of head. The idea of an artificial beaver dam is that at the upstream side of the property is the site of a past beaver dam so this bodes well environmentally. I can build a spill way into the dam to compensate for our spring run off that changes our small creek into a raging torrent. Rarely during the flooding do the natural beaver dams sustain much damage. This time of year it is not uncommon to have a month or two of temperatures in the twenties or thirties, thus my thought of a pipe buried a couple of feet underground even though it should have running water in it.
Thanks.
