"Drinking water and wastewater treatment are essential to modern life and the Nation's economy. Therefore, it is critical that we enhance the security and resilience of the Nation's drinking water and wastewater infrastructures, collectively known as the 'Water and Wastewater Sector' (Sector). The purpose of this 2015 Water and Wastewater Sector-Specific Plan (Water SSP) is to guide and integrate the efforts intended to secure and strengthen the resilience of the Sector's infrastructure. This Water SSP tailors the strategic guidance provided in the 'National Infrastructure Protection Plan' (NIPP) 2013 to the unique operating conditions and risk landscape of the Sector."
