Arcgisa explains that water has higher concentrations of iron and manganese which are not harmful to health
The first effects of the severe drought in Campo de Gibraltar are beginning to be visible in the houses. The supply of drinking water in various parts of the region has begun to suffer from coloration and turbidity in recent weeks.
Arcgisa, the company responsible for the water supplies mainly from the reservoirs of the region, has attributed the colour of the water to the low level of the reservoirs and to a natural phenomenon which is not dangerous to health.
The region will have water restrictions this autumn due to the most severe drought in the last 25 years;
“Although the content of these compounds is not harmful to health, the appearance of the water is not appropriate,” admits Arcgisa.
Due to the composition of the soils, iron and manganese are naturally present in the water of the reservoirs in high concentrations. “In a situation like the current one, with intense and severe drought, these concentrations become even higher, making it difficult to make the water drinkable”, the company continues.
To solve the problem, the water is made drinkable using a special procedure. “However, sometimes if there is a rapid increase in the concentration of these compounds in the water supplied to the treatment plants, some of the iron and manganese pass into the supply network causing the water to become coloured”, explains Arcgisa in the video.
Water turbidity in the region has also increased over the past week as a result of a breakdown in the reservoir water pumping system that occurred last Wednesday 18th. This breakdown affected practically all the municipalities in the region.
Once the water supply was re-established, the flow dragged mud and other impurities from the walls of the pipes, which have added to the natural oxides in the water. The same thing happened in other parts of Campo de Gibraltar.
“Since Friday, the colouring of the water in the tanks in Algeciras is getting better. Quality analyses, chlorination and other parameters have been carried out at all times. If there is some coloration left in some areas it is because the tank that supplies it has a greater capacity and takes longer to renew completely”, explained the company.
