Johnnie, You may know that a siphon cannot normally lift water over high points in a long pipe. This is because water usually has some dissolved gas or bacteria make gases. These gases accumulate at high points unless you include an air release valve. I have personal experience discovering "a point too high" on a 36-inch pipe inside a wastewater treatment plant. The pipe capacity was supposed to be 40 million gallons per day. But flow maxed out near 18 mgd, even with 4 feet of extra upstream head because the secondary clarifiers flooded during a storm. The conventional solution would be to realign about 200 feet of 36-inch pipe, costing about $500,000 in this pipe-congested area. Instead, I added a $300 vacuum pump to suck on the outlet of the existing air release valve. Instant 40 mgd capacity. You can use the same principle to maintain gravity flow over "humps" in the pipe up to about 25 feet above sea level.

Mark, Thank you for your comment and suggestion! If the engineers on this project fail to properly re-arrange land mass formations until the ocean extended end of the conduit will always be submerged even in low tide - your vacuum pump will be very important. In fact - every conduit on every installation should have a vacuum pump as a contingency factor. A small price to pay to ease a huge headache. In areas off-grid - a small DC unit could be powered by a small battery/solar/panel. Thanks again, for the improvement, Johnnie

Proposal cites 5 sub-proposals, all of which are by the same author. It thus does not meet the contest prompt which requested that authors create an integrated vision that combines multiple ideas from other contests.
