San-Rafael hydro development
This project is located on the Santiago river in Nayarit State, Mexico, downstream Aguamilpa HPP, and has been designed to control the HPP daily discharges.

It includes:

  • non-overflow concrete gravity dam of 259m long and of 21m height;
  • broad crested spillway of 68.5m wide with 6 bays that closed with radial gates;
  • antechamber concrete gravity wall of of 125 m long and of 20 m height;

Ukrhydroproject company elaborated design of the gated bays of the flood and construction water spillways.

Main parameters of the project:


total reservoir storage 12.2 mln. m3
max discharge through the structures 6350 m3/s

Buffer HPP of the following parameters shall be constructed:


HPP capacity 24 MW
Design discharge 187.5 m3/s
Design head 14.7 m

Ukrhydroproject company elaborated detailed design of the spillway dam and coordinated supply of eight sector gates of 8.5 x 15.41 x 16.0 m with hydraulic rams and oil pressure units; the company also provided supervision of construction and erection works, and elaborated the preliminary study for the future hydropower plant.
