I am not clear about your question completely, but here is my answer of
there is any worshipping of water, or traditions involving water?.
Yes there is concept of water worship in Hinduism from Rug-Vedic times. There is Apah Suktam (water Hymn ) in Rug-Veda 10.3 .Where water is revered.
आपो हि ष्ठा मयोभुवस्ता न ऊर्जे दधातन ।
महे रणाथ चक्षसे ॥१॥
āpo hi ṣṭhā mayobhuvastā na ūrje dadhātana ।
mahe raṇāya cakṣase ॥1॥
O Water, because of your presence, the Atmosphere is so refreshing, and imparts us with vigour and strength. We revere you who gladdens us by your Pure essence.
ईशाना वार्याणां क्षयन्तीश्चर्षणीनाम् ।
अपो याचामि भेषजम् ॥५॥
īśānā vāryāṇāṃ kṣayantīścarṣaṇīnām ।
apoyācāmi bheṣajam ॥5॥
O Water, may the divinity in Water dwell in the Farm lands, O Water, I implore you to give nutrition (to the crops).
In Hinduism there is a tradition worshiping gods with water.
Tarpana OR Arghya means offering , this is given to all the gods . So gods are worshiped with water by offering water to them. Surya Arghya or worshiping the Sun with water is widely practiced in Hinduism.
There is a step of this Arghya pradanam (offering ) in Sandhyavandan – which is mandatory religious ritual performed, traditionally, by Dvija communities of Hindus.
