Paravani River HPP Diversion Weir

The Paravani River Diversion Weir (often associated with the Paravani HPP collector system) is a key infrastructure installation located near the village of Khulgumo, just outside Akhalkalaki. Situated at the confluence of the Paravani and Shaori rivers, this engineering complex regulates water flow diverted through a 14-kilometer pressure tunnel toward the power plant downstream. Unlike the massive lake from which the river flows, this specific point represents the intersection of the natural volcanic river systems of the Javakheti Plateau and modern hydro-energetic engineering.

Hydro-Engineering on the Volcanic Plateau

The diversion structure sits in a deep, rocky canyon carved by the Paravani River through layers of ancient basalt lava flows. The volcanic geography of the region shapes the entire hydrologic network, characterized by high elevations, cold alpine climates, and a landscape dominated by subalpine steppe. This facility channels the high-altitude water resources of the plateau, redirecting flows to generate clean energy while maintaining the baseline ecological flow of the original riverbed.

Historical and Regional Significance

Developed as part of Georgia's modern energy strategy, the facility highlights the strategic importance of the Samtskhe-Javakheti region in regional water resource management. The surrounding area preserves a stark, minimalist landscape of volcanic plateaus and deep gorges that defines the southern borderlands of Georgia. The juxtaposition of concrete hydraulic engineering against rugged basalt columns illustrates the industrial transformation of this historical highland territory.
