Duct is tough. You could use it as a tow rope. Just cut a slot on the side of the block, skip the duct into the slot and tie a piece of stainless wire around the block so the duct cannot come out of the slot if the block comes to rest with the slot up. We used tape to keep the blocks from sliding up and down the duct when placing it. Once on the bottom, the duct floats to the top of the cavity in the cinder block.

If you can get those half cinder blocks and cut a slot in the side they work pretty good. I calculated how much additional weight you needed once but that was many years ago.

On a water crossing you will need cinder blocks every 10 feet or so to hold it down. Chop a hole out of one of the sides large enough so the duct can slip inside one of the cavities.

You don't need that large of duct for this, 1" or 1.25" at the most would be sufficient. Expect to pay around 0.25 per ft for 1" and 0.35 per ft for 1.25", ballpark numbers. 8. If it's going to all be in conduit, I would use 12F drop cable instead of "normal" loose tube cable. Actually on a project like this I would just direct bury the 12F drop with a small drop plow everywhere possible to save money. 9. We get some nice 17x30x15" HDPE Carson handholes from Milennium in the $70 range. I think they have a smaller size yet for around $40. 9a. NOPE... I actually tried this, it was a dismal failure. It's hard to make strong, thin, concrete sections.

There are 8 current homes, haven't looked at a platt map yet to see how the lots are legally divided, so there is that. This is about interconnecting and somewhere in the mix bringing in interwebs. To run past all the current lots is roughly 8050 feet. There would be 4 "fingers" the longest being 3300 feet, passing 3 houses with the longest distance between those 3 being 1400 feet, 300 feet of this would be underwater. This is not a ROW, issue, they don't want it in ROW, I assume they need some sort of legal easement on record for the duct. I know zero about this. Here are some questions: 1. the underwater part. is that normally duct or just underwater fiber. 1a. this pond is stocked by DNR, does that require some crummy permit to drop fiber into even though its privately owned, I don't know what the trade off is for DNR stocking. 2. When passing a lot, do you normally put a handhole in each lot? 3. if a utility ROW is crossed, does that need a permit? 4. Whats the specific terminology, I think its easement, that makes the duct accessible, like ROW, legally even if the property changes hands 5. How does one get this buried cable/duct into a location service database 5.a when a locate is called in who pays? (USIC is the locating agency around here) 6.how much longer will this list of questions get before it gets too hard In this instance, it will all be cut trench, that's free, for them. This is all unincorporated land in a county. however there has been a history of forced incorporation attempts. should that happen, what happens with this duct? assuming there is some chatter on this, anticipate more detailed questions on tech specs
