This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
浗 combines 氵 (water) with 求, but the exact historical development and original meaning are uncertain.
The water radical 氵 beside 求 suggests something related to water, but without a clear meaning, picture a mysterious water droplet seeking (求) a purpose.
For キュウ, imagine a curious (キュウ) water droplet searching for its meaning: curious -> キュウ.
