I don’t have much in the way of links, but I can give you an overview.
We have a fair bit of vertical scale in the terrain here. We extract our water from a shallow well in a natural crevasse between ridges. It is made of concrete blocks stacked in a circle, filled with gravel and pinned with heavy rebar. The above ground part is finished in a regular fashion, with the blocks filled with concrete and a concrete cap. The well is built of a circle of 12 blocks, and is about 16 feet deep- where we encountered hard bedrock. An underground stream flows over this bedrock, which we extract from.
This raw water is pumped to a 300 gallon manifold tank about 160 feet above the extraction point using a 1HP centrifugal pump. From there, it flows down to the processing facility, where it is sediment and carbon filtered before flowing into either the 2600 gallon cistern, or back up the hill a bit to a 450 gallon upper campus distribution tank. Water passing through the processing facility is filtered and chlorinated, with the exception of the upper campus water, which is only filtered.
The upper campus water flows to cabins in the upper campus, and also serves as the input water for the RO system. The RO source water is pressurised by another centrifugal pump to 70psi, and is fed through a pair of 150GPD membranes after being filtered to 1 micron and passed through another carbon block. We run a 4:1 “waste” ratio to give us good life on the membranes (typically a year). The mineral rich “brine” flows into the 2600 gallon cistern and is used in the regular water.
We warehouse the drinking water in a 500-gallon tank at the processing facility.
There is a dual distribution system for water on campus. From the cistern at the processing facility RO water and regular water flows through underground tubing to a network of 5 utility huts where it is distributed to various homes and outbuildings. Each building then passes the main water through another carbon block to catch chemicals and chlorine, and drinking water gets mineralization and carbon again at the point of use.
The underground distribution network also carries 3 phase power, HVDC for solar, separate fiber optic networks for security, control, intranet, and ISP, as well as cat6 cables for RS485 control subsystems. The tank levels, pump controls, power distribution and usage monitoring, emergency and automatic casualty control shutoffs, etc are all operated over rs485 and modbusTCP to a server. It’s a lot of off the shelf stuff and some custom stuff that i have built. Someday I need to do a write up on that lol.
Anyway, that’s the view from space.
