In order to keep our water environment healthy, we need reliable and sustainable water services. However, in some parts of our country, the amount of water being abstracted and lost through leakage is unsustainable, and damaging to wildlife and the environment. Some areas of Scotland still suffer from pollution caused by inadequate treatment of sewage and by sewer flooding. Scottish Environment Protection Agency (SEPA) estimates that 2062km of rivers, coastal waters and estuaries are at risk from sewage pollution and other Scottish Water (SW) related activities.
