Treatment System. Two new surface water intake pipes will be installed approximately 219 m into Lake

of the Woods and a water reject pipe will be installed approximately 187 m into the lake. A new water

treatment plant and below ground reservoir will be constructed to service the community, and new

water service piping will be installed throughout the community. The treatment and distribution system

will be designed for fire flow capacity to design year 20, based on projected population growth. The

treatment system upgrade plan is attached.
