The Smiths Falls Drinking Water System is comprised of the water treatment plant and distribution system which together provide a supply of potable drinking water to approximately 10,000 people in Smiths Falls as well as to residents of the Atironto Subdivision in Montague.
An intake draws water from the Rideau River and directs it into the water treatment plant.
Water is treated by a high rate dissolved air floatation clarifier (which floats particles to form a sludge which can be removed). This is followed by carbon and sand filtration where further particle removal takes place. Other treatment processes involved include UV disinfection, chlorination with chlorine gas, corrosion control, fluoridation, residue management and de- chlorination. The distribution system includes many kilometres of pipes and a water tower for storage. The Smiths Falls Drinking Water System operators must adhere to the strict requirements for the treatment, testing and distribution of drinking water specified in the Safe Drinking Water Act. The water is consistently in compliance with Ontario Drinking Water Quality Standards.
Ontario’s Clean Water Act was created specifically to protect drinking water at the source rather than simply relying on water treatment to deliver safe, clean water. Because of work completed under the Clean Water Act, Smiths Falls now has a mapped Intake Protection Zone (IPZ) that is protected through policies in the Mississippi-Rideau Source Protection Plan.

The Perth Drinking Water System is comprised of the water treatment plant and distribution system which together provide a supply of potable drinking water to approximately 6,000 people in the Town of Perth.
An intake draws water from the Tay River and directs it into the water treatment plant.
Raw water from the river is double screened to remove solids. Water then enters mixing chambers where a coagulant is added to bind with remaining solids. In large flocculation tanks, the coagulant binds fine particles together forming “floc”. Water then sits in settling chambers where floc sinks to the bottom and clear water can be taken from the top. Water then passes through filters to remove remaining microscopic particles and any taste and odour. The water is then disinfected, pH is adjusted and fluoride and chlorine are added. The distribution system includes many kilometres of pipes and an elevated tank for fire protection and pressure buffering. The Perth Drinking Water System operators must adhere to the strict requirements for the treatment, testing and distribution of drinking water specified in the Safe Drinking Water Act. The water is consistently in compliance with Ontario Drinking Water Quality Standards.

The Ottawa Drinking Water System consists of the Lemieux Island Water Purification Plant and the Britannia Water Purification Plant that supply approximately 850,000 people with drinking water.
Intakes draw water from the Ottawa River and direct it into the water treatment plants.
Raw water from the river is screened to remove debris. A coagulant is then added prior to the water entering the mixing chambers where it follows a spiraling flow pattern to promote gentle mixing (flocculation). The coagulant binds fine particles together forming “floc”. Water then flows into sedimentation basins where floc settles to the bottom. Clear water then flows from the top through filters. Water is then disinfected using chlorine and ammonia, pH is adjusted for corrosion control and fluoride is added before the water enters the distribution system. The City of Ottawa Drinking Water System operators must adhere to the strict requirements for the treatment, testing and distribution of drinking water specified in the Safe Drinking Water Act. The water is consistently in compliance with Ontario Drinking Water Quality Standards.

The City of Ottawa supplies drinking water to 1,320 people in Munster Hamlet. There are two municipal wells constructed between 1969 and 1973 which are 116 metres and 122 metres deep.
The municipal wells draw groundwater from the Nepean Sandstone Aquifer which is well-known for supplying a good volume of quality drinking water.
Chlorine is added to the well water to disinfect it. Treated water is then stored in an underground reservoir before entering the distribution system. The City of Ottawa drinking water system operators must adhere to the strict requirements for the treatment, testing and distribution of drinking water specified in the Safe Drinking Water Act. The water is consistently in compliance with Ontario Drinking Water Quality Standards.

Approximately 1,000 people in Merrickville are supplied with drinking water provided by the municipality (Village of Merrickville-Wolford). There are three municipal wells constructed between 1960 and 1973. In 2012, the provincial government provided funding to the municipality to undertake a project to better protect the wells. This involved extending the well casings so that water is drawn exclusively from a deeper, less vulnerable aquifer.
The municipal wells draw groundwater from the Nepean Sandstone Aquifer which is well-known for supplying a good volume of quality drinking water.
Each well pumps water to the main pump house where chlorine is added to disinfect the water. The treated water is then pumped into the distribution system of piping throughout the town to serve individual residences and businesses. The Merrickville drinking water system operators must adhere to the strict requirements for the treatment, testing and distribution of drinking water specified in the Safe Drinking Water Act. The water is consistently in compliance with Ontario Drinking Water Quality Standards.

The Carleton Place Drinking Water System is comprised of the water treatment plant and distribution system which together provide a supply of potable drinking water to approximately 10,000 people in the Town of Carleton Place.
An intake draws water from the Mississippi River and directs it into the water treatment plant.
Raw water from the river is pretreated and screened to remove solids. Water then enters rapid mixing chambers where a coagulant and polymer are added to bind the fine particles together forming “floc”. Fine sand is added to help the floc settle quickly in the two settling tanks. A collection hopper at the bottom of each settling tank collects the floc while the clear water flows into collection troughs at the top. Water then passes through filters, is disinfected using chlorine gas and then fluoride is added before the water enters the distribution system. The Carleton Place Drinking Water System operators must adhere to the strict requirements for the treatment, testing and distribution of drinking water specified in the Safe Drinking Water Act. The water is consistently in compliance with Ontario Drinking Water Quality Standards.
