In which part of the nephron, does maximum reabsorption of water occurs?

The human excretory system is composed of 1 pair of kidneys. 

The nephron is the structural and functional unit of the kidney. 

The body of the nephron is divided into renal corpuscle, PCT (Proximal Convoluted tubule), Henle's loop and DCT (Distal Convoluted tubule). 

The PCT (Proximal Convoluted tubule) is lined by cuboidal epithelium with a brush border. 

The brush border increases the surface area for the absorption of water and other substances. 

The proximal convoluted tubule in the nephron is the site where the maximum water absorption occurs, with up to 90% of the filtered water being reabsorbed.
