Key Facts

The following facts give some idea of the scale and complexity involved in providing clean, safe drinking water and disposing of waste water from homes and businesses across Scotland, 365 days per year.


Thousands of assets are operated and maintained - over 47,000 kilometres of water pipes, 50,000 kilometres of sewer pipes, 1837 waste water treatment works (including 1206 septic tanks) and 297 water treatment works plus pumping stations, sludge treatment centres, reservoirs.


Scottish Water has around 5 million customers in 2.4 million households. 

Water Quality

Around 1000 tests are carried out every day on samples taken from water treatment works, service reservoirs and customer taps.


2.1 billion litres of water is provided every day and nearly 1 billion litres of waste water is taken away and treated before being returned to the rivers and seas.


Scottish Water is the sole provider of water and waste water services to an area of 79,000 square kilometres (over 30,000 square miles), a third of the area of Britain.  And Scotland has a longer coastline - over 11,000 kilometres (over 6,800 miles) - with a small and relatively dispersed population which requires a large number of small water and waste water treatment works.

Ranking and Turnover

Scottish Water is the fourth largest water and waste water services provider in the UK and at £1 billion it is in Scotland’s list of top 20 businesses by turnover.     

Head Office and Operations

Scottish Water’s head office is in Dunfermline with principal offices in Aberdeen, Dundee, Edinburgh, Glasgow and Inverness.  It employs almost 3,400 people across Scotland.
