Jakom has contributed to increase the safety of the population in the region of Sacramento in the United Stated, California. The American state has given the order to equip Folsom Dam with an ‘emergency spillway’, that starts to operate when the water level of the Folsom Lake becomes too high and therefore the risk of floods. The Spillway consists of a 1100 ft. long concrete channel that can guide the water, via 6 water gates, of the Folsom Lake to the lower American River in a controlled manner.
The budget for this project is 900 million dollars and must ensure that the Sacramento region receives a protection level of 200 years, what means that there is a chance of flooding once in every 200 years.
Jakom has produced the cylinder rods for the 6 water gates. The 13 cylinder rods in total (2 per water gate and 1 spare) of each 13.1 metres in length and a diameter of 200 mm, are all equipped with an extreme accurate measuring profile over the complete length of the rod. This profile allows to place the cylinder rod – and therefore the water gates – in any desired position, in order to regulate the amount of water that is drained per minute.
The project must be fully completed by the end of 2017.
