I've been in Egypt and India - they aren't that different, and it's Indian companies that are working on and helping financing these megaprojects in Egypt via the credit line established after the pandemic [0] and it's Indian companies like Wabag that are implementing water treatment projects in Egypt [1].

Larsen & Toubro, Wabag, SP Group, EIL, Afcons, and others tend to have a chokehold on implementing and executing these kinds of projects in MENA because they co-finance projects with Gulf capital players who tend to have capital stakes in these Indian players as well.
Nowadays, farmers have shifted to directly using groundwater, and just pump as much water as possible from wells (thus depleting them). This is exacerbated by: 1) Relying on flood irrigation (ie just let water flow across the field and evaporate, vs drip) 2) As temperatures rise, using even more water
The situation was already pretty dire, and despite various efforts, it's getting much worse.

"We reviewed 160 journal articles, along with supplementary data and reports from GW, agriculture, and meteorological authorities. Our focus was on GW depletion in India, with particular emphasis on GRACE satellite data, in situ observations, and the influence of hydrogeological conditions, anthropogenic activities, and climatic disturbances. GRACE observations reveal significant depletion, particularly in Eastern Uttar Pradesh at 7 cm/yr rate from 2002 to 2022, while localized in situ data highlight Punjab as the most rapidly depleting area, with a rate of 46 cm/yr (2003–2012)."*
