How are water pumps intended to work when fully working? Namely:

- What is groundwater? Is it just another name for the moisture of the ground we can see, or is it something being calculated in the background?

- What are groundwater layers? The Deep Water Pump is described as pumping water from a deep water layer. Is this the only other layer, or are there more? What is the difference between them? The deep water pump description states that draining the deep water layer may drain the upper groundwater layer, in what ways do groundwater layers interact?

- Are there areas / biomes where water pumps do not work, or where they work particularily well?

Good questions. I'll answer them in short with how they currently are, though this is something that is not finished at all. It may gets changed and certainly gets improved to be better and more smooth and intuitive.

In general, there is a relation to how groundwater and groundwater pumps work in reality.

- Groundwater is basicly an invisible second moisture level with a way larger storage and not directly affected by rain or such stuff, as it is under the surface. There is exchance between groundwater and the surface moisture (the visible moisture stat). Currently groundwater is not visible, but there may be devices like the ground-penetrating scanner in the future to measure it. You can still get a good idea of where groundwater is, as surface moisture is generally higher where groundwater is also higher.
- The groundwater normally is sustainable, so groundwater pumps nearly don't consume their water while pumping. Though their pumping speed depends on the groundwater level. They won't work if there is no groundwater (or too less).

- The description of the deep water pump is not optimal, as it mixes RL-description into the gameplay stuff and leaves out the important gameplay information. What this pump does is basicly that it aggressively pumps out the groundwater in a non-sustainable way. You get a lot of water, even in deserts with little to no groundwater, but it lowers the groundwater over time which then may/will result in a surface moisture level drop (as it often does irl).

TL;DR:
* Groundwater pump: More sustainable water source in areas with medium or higher groundwater.
* Deep water pump: More powerful water source by overexploration which may cause long-time damage to the environment.

- Water pumps won't work near ocean (salt-)water. Apart from that there is more groundwater in biomes which generally are more wet. Like forests and swamps have lots of groundwater, savanna a lower amount, arid biomes even less and deserts little. Though there normally is more groundwater in areas, where there are larger bodies of natural water during map generation (like a river or lake).

How do i irrigate my crops?

There are two current ways to irrigate crops.

The first is to set a irrigation level of the growing zone, which is an option you can select when you click on the growing zone. Colonists will then haul any water you have in stockpiles or resevoirs to these growing zones and use them to bring the soil moisture level up to the threshold you set.

The second way is to use a building called an "Irrigation Plant" to automatically irrigate your crops within its radius. It works similarily to the first method and is unlocked through research. You first build it, then you click on it and set the irrigation level you want. Colonists will then bring water to the irrigation plant and the irrigation plant will bring up the moisture level of all tiles in the radius to the set threshold.

Is it possible to dam a river to make a lake or dig canals / moats?

My jungle base keeps flooding. How do i stop that?

I think the only way is to not build on low elevation or wall off and roof the entire area, because moisture pumps dont seem to get rid of water on top of floors and are normally are not fast enough to prevent a dirt area from being flooded by rainfall

@scheeks: You can build walls or sandbags to block some water, though you cannot create a artificial lake / reservoir. That would be a really cool idea, though I need to check how much work it would need to code. Digging/changing terrain was removed during develpoment since it had *huge* performance costs to an unplayable degree. Maybe it gets added again if I want to inveset enough time in optimizing it.

Terrain flooding will get improvements in the next update and an overhaul of the pumping stuff is probably needed too. Currently the best is to build at high elevation or use sandbags to block water from flowing in for base (though doors mostly).

How do I get my pawns to fertilise soil? Setting a fertilisation threshold doesn't seem to do anything, but I can't find any option to make fertiliser anywhere either.

How do i get my crops all the way to harvest? So far, my best attempt was millet, the luckiest of which got 53% grown before two storms happened in a row and everything flooded. Crops have died from using up all the nutrients in their soil, being too dry, wet, cold, or warm.

I saw the text in the monsoon about setting up dams, how do i build dams? Water got into every room of my mountain-dug base like it had no roof, so it looks like both natural stone walls and constructed walls have no effect on water, along with natural and constructed roofs. Is there some special research required for dams?

This mod looks really, really cool and I want to use it for every game if I can figure out how to have a playable game with it.

parts of my base are on lovver(my double u key is broken) terrains and i'm in the monsoon event, parts of the base are novv being destroyed by the vvater, hovv do i build up the soil or highten the terrain in and around my base so that chunks of it aren't destroyed by vvater?

You can't change the elevation (for now). You can build walls or sandbags as dams around your base so it stops the water from flowing in. Also roofing the rest of your base if you haven't will prevent rain from dropping there.
In general the best way to prevent this is to choose a better spot for building your base at the start.

Walls do block water. If this is the case in your game, there is some bug or error going on. Probably a conflict with other mods.

Will modded animals spawn in these new biomes? Had another mod that only spawned vanilla game animals.

hi there, I like the mod, it still needs to be worked on but very cool nevertheless.
I have a question on how am I supposed to farm, I allready plowed the terrain and the soil is hidrated the temperatures are about right to start corn cultivation but none of my colonists are planting anything despite not having so much to do..

I'm enjoying some of the additions to this mod for sure, as I always thought farming was a bit too easy in default Rimworld, where so long as you didn't get obnoxious blight you were pretty much guaranteed infinite food the moment you got a sun lamp up and running.

That being said, have you looked into getting this working alongside some other mods? I noticed for instance that it currently does not seem to respect the fertilization or irrigation systems from Bad Hygiene.

@Roffe: Animal mods needs patches to spawn in new biomes. Currently Alpha Animals has such patch and Jurassic Rimworld is working on one. Others will probably come in the future.

@Based Count Dooku: That sounds like the problem with Prison Labour, which was already talked about here like 50 times. Remove that mod and see if it works. Otherwise post logs and such in the bugs section.

@Galactor: Mod compatibility will come later, when this mod works well enough on its own. Bad Hygiene is one of the mods with higher priority, as it would really benefit from patching better compatibility. But this would also be a lot of extra work.
