I have some site water issues. I have asked a couple of folks to give me a quote on drainage via piping and build up remaining low sides of a pond to contain all the water (current overflow is a low bulkhead allowed to drain at grade into a swale) I get back a quote to build another swale to tr direct water again, with a skidsteer. I can operate a skid and could probably create an ugly swale myself with an extra day of skid rental. I'm also not sure a swale will work in this application of rolling landscape.. maybe I'm wrong though. Thinking out loud, I would like - if cost effective, to drain the all of the pond's site pan to the pond from a wet spring, around a corner of my tilled garden, around a hoop house and overflow from rain collection water storage. We would also need to install overflow piping that is quite badly needed on the pond (currently drains out in swale flooding the garden and orchard. Then, pipe everything down to a point where it could, when funds allow run through a couple of low head turbines approx. 500-600 feet away from the pond, for now they will drain into the ditch. The ditch runs down the county road, along my property to a corner where it is then ran into the creek. I would like to capture the energy from both the ditch water and the site water that needs draining anyway. The site has about 20' of head, ditch has about 30' immediately adjacent to my property line and probably another 100' along my neighbors property line. I think an earth worker can probably do the fine grade water pan work and build up the remaining sides of the pond with a dozer/loader as well as trench with a mini-ex in a day, probably 2 man days to also lay the piping and backfill. (BTW any earth workers in SW MO [North of Springfield] in the crowd looking to bid this work? and in general to earth workers: is a civil engineer needed to figure grade sloping and pipe sizes?). After grade is established and were draining well, then we can build the dam, redirects from/to ditch (if possible) and turbine box. I have just enough schooling and engineering background to probably "homestead engineer" rent equipment and pipe this "good enough to work- enough to drain moderately well!". But, is this idea Is this just too costly an endeavor for a homestead prepper wanting to make power in the rain while keeping his garden from flooding under 'normal' seasonal rains, possibly house too from flooding in a bigger event. Construction and Engineering minded Bear nationals, could I please get your thoughts?
