Building a bridge?

[3Ts]

Well I doubt the creek has 60 feet fall but it’s probably way more than 10 gpm. You’d probably need a battery or so other storage device. Does anyone know how much power it would take on a continuous generating cycle to power a house?

That depends on a lot of factors. There are folks on here that use generators from 7.5 KW to the 22KW Generac. What will you be running?

I was referring to a hydroelectric generator which I unfortunately don’t have a creek anywhere close to big enough to use one. The backup generator has to be big enough to handle the biggest load on demand. The hydroelectric generator or really any generator could be much smaller running 24/7 and using a fairly large battery.

You might find precast box culverts in your area. Some have bottoms and others sit on slabs.

You'll need about a 10 gal/min flow rate with about a 60 foot fall to generate 1Kw of electric power.

that 60 ft. fall would be the source of the water to the point of use in the case of a screw type generator. there is a blacksmith in upeer New York who makes his electric in this way, I didn't find the link, but he makes a very good amount of electric with that generator!..

Use steel stringers so the bridge will be there after you are gone. Rather than being non useable while you are here.

I priced one of those to replace a four foot culvert, the estimate a little more than $18000.

They must be priced for Gov't buyers using taxpayer money.

No, concrete isn't cheap. That's what it costs by the time you buy, have it trucked, and excavator to dig the ditch.

If you are using timber forget the 4x6. You want a deep section. 2x8, 2x10 etc.

4' dual wall plastic culvert is $42 per foot governmental cost here is Missouri. The cost of larger culverts is extremely high.
