π§ Water Pumps Expanded
Your water supply grows with your industry: upgrade your groundwater and seawater pumps in place to level II and III, no tearing down, no new pipes.
Level II pumps 3 times as much water as the vanilla pump, level III 6 times as much: a groundwater pump III gives 288 water / min, a seawater pump III 648 seawater / min, on the same spot as the pump it came from.

Features
- β¬οΈ Upgrades in place: select a pump and press Upgrade. It keeps its place and its pipe (a groundwater pump also its deposit); the game delivers the cost difference like for any other upgrade
- π± Groundwater pump II / III: 144 / 288 water per minute (vanilla 48), 360 / 720 kW
- π Seawater pump II / III: 324 / 648 seawater per minute (vanilla 108), 300 / 600 kW
- π Seawater pump (tall) II / III: the same for the tall seawater pump, at 600 kW / 1.2 MW
- π° Second outlet on III: one pipe III carries 450 a minute, so the seawater pumps III get a second outlet right beside the first
- π The game's own pumps, made bigger: groundwater pumps 1.15x and 1.3x, seawater pumps 1.25x and 1.5x as tall and wide (their pipe still reaches into the sea the same way); icons with a II or III badge
- π§ One build menu entry: Seawater pump I, II, III, then the tall one I, II, III
- π· Costs: construction parts II for level II (the tall seawater pump II: construction parts III), construction parts III and steel for level III
- π¬ Research: four new nodes in the research tree, right after the research they need

How to start
- Research Groundwater pump II (after Groundwater pump and Pipes II) and upgrade a groundwater pump.
- Research Seawater pump II (after Thermal desalination and Pipes III) for both seawater pumps.
- Research Groundwater pump III (after Groundwater pump II and Construction III) and Seawater pump III (after Seawater pump II), then upgrade again.

Good to know
- π Speaks all 21 languages of the game.
- Level II groundwater pumps need pipes II, everything above that pipes III.
- A groundwater pump draws from its deposit what it pumps, so a bigger pump empties it faster; rain fills it again.
- The fast mode of the vanilla seawater pumps is not on level II and III: a pump in fast mode keeps the normal mode when it is upgraded.
- Can be added to existing saves, but not removed once you have built a level II or III pump.
- Made for Captain of Industry 0.8.7.
The models and icons are made from the game's own pumps while the game runs. No game files included. Contains Harmony 2.4.2 (MIT licence).
