Scottish Water
Scotland has an area of 79,000 square kilometres and a coastline of over 11,000 kilometres. With a small and relatively dispersed population a large number of small water and waste water treatment works are required.
The company is the sole provider of water and waste water services to around 5 million customers in 2.4 million households. Thousands of assets are operated and maintained – over 47,000 kilometres of water pipes, 50,000 kilometres of sewer pipes, 1,837 waste water treatment works and 297 water treatment works plus pumping stations, sludge treatment centres, and reservoirs. Each day the company supplies 1.3 billion litres of clean water and nearly 1 billion litres of wastewater is taken away and treated before being returned to the rivers and seas.
