Impouding and RWE of Lapela in Monção

Águas do Noroeste, S.A.


Water collection system and pumping station, consisting of a building with 313m² deployment area that encompasses a vertical pit dug in granite rock with 6m in diameter, 23m deep. The basis of this well is connected to the Minho river by a gallery of 1,10m x 2,10m x 23,5m long, which has 2 outlet water pipes.

The collection system consists of two submersible pumps with a unit rate of 468m³/ha at a manometric a height of 70,3m with operating system of 1 + 1, 125kW of unit capacity and maximum collected volume of 468m³/h, powered and controlled electrically from the Water Treatment Plant and with installed power of 630 kVA in infrastructure.

Pumping Pipeline of Raw Water: 1800m, FFD DN 450, PN 10, with protection device to the hydraulic shock of 2m³ volume and Rated Pressure of 16 bar.

Water Treatment Plant: Current Treatment Capacity = 468m³ / h (130 l/s); Future treatment capacity = 702m³ / h (195 l/s). Installed capacity in the infrastructure of 630 kVA.

Treated Water Reservoir composed of two cells of about 1.850m³ each, making a total reserve of approximately 3.700m³.

System sustained by a generating emergency set of 550 kVA power in emergency operation.

Pumping Stations of Treated Water: Pumping Station EE01 consists of 2 electric pump groups, submersible pump and external motor. Each group of 110 kW of power, will be able raise a flow rate of 76.6 l/s at a height of 100mca through pipeline of FFD DN 300, PN25.

The Pumping Station EE02 consists of 2 electric pump groups, submersible pump and external motor. Each group of 200 kW, has the capacity to raise a flow rate of 118 l/s at a height of 105mca through pipeline of FFD DN 400, PN16.

Installed power supply of 630 kVA in infrastructure.

Monitoring, Automation and Remote Management: fiber optic network installation between Water Collection and Water Treatment Plant for infrastructure command through the Water Treatment Plant, installation and programming of supervision and monitoring equipment of Water Treatment Plant.
