One of three waterfalls that surround the City of Owen Sound, Inglis Falls is the best known and most visited. Situated in the heart of the 200-hectare Inglis Falls Conservation Area, Inglis Falls is an 18 metre high cascade, created by the Sydenham River meeting the edge of the Niagara Escarpment. The erosive power of the water has carved a deep gorge at the base of the falls. On a clear day you can see down the valley into the City of Owen Sound and out to the Owen Sound harbour.

There is something for everybody; a viewing platform for those unable to see over the stone wall, 7.42 km of trails of various difficulty, access to the Bruce Trail, more than 20 species of ferns, bird watching opportunities, a series of geological potholes, historical remains of a grist mill and water filtration plant, picnic facilities and Niagara Escapement Discovery Shop, displays, video and visitor information.

Grist Mill

In 1843, five years after the founding of Sydenham Village (now the City of Owen Sound), 30 year old Peter Inglis emigrated to Canada and settled in this area. This enterprising young Scotsman and millwright saw the potential of harnessing the powerful cascade of the Sydenham River.

In 1845 Inglis purchased a small existing grist mill built two years previously by a Mr. Boyd, and 300 acres of deeded Crown land. It was in 1862 that Inglis replaced the old gristmill with a new four-storey mill that produced flour, bran and shorts (feed for animals).

Other ventures of Inglis' included building a sawmill a quarter of a mile downstream of the falls. Peter Inglis also built a woollen mill on the eastside of the river on the brink of the falls. Here were manufactured tweeds, flannels and "rainbow" blankets, so called because of the three coloured stripes at each end. The woollen mill was destroyed by fire around 1885. It was rebuilt only to burn down again in 1901. The family never told Peter of the loss, and the woollen mill was never rebuilt.

Management of the mill was passed on to Inglis' oldest son, William A., in 1886. William's son, Victor, managed the mill until 1932. Eighty-seven years of steady operation under the Inglis family name is an amazing record which very few industries in this area of the province can surpass or equal.

In 1932, the property was obtained by the City of Owen Sound for water rights. The mill was idle for two years, until purchased by Emil Henkel. He ran the mill until 1945 when a fire completely destroyed it.

In 1960 the former North Grey Region Conservation Authority (now the Grey Sauble Conservation Authority) acquired what is presently the Inglis Falls Conservation Area. Today all that remains of that earlier industrial scene are the family home, a stone building, the silent millstones and the enduring beauty of Inglis Falls.

Water Filtration Plant

The Rockford water filters were built in 1910 and served an area of Owen Sound that was being expanded at that time. Water was taken from the Sydenham River above Inglis Falls and cleaned in the filters before sending it on to Owen Sound. These filters provided 2,500,000 gallons of water per day to homes and factories. The whole system was based on gravity.

The project began in 1910 and was completed by 1912. The project consisted of a water works dam, a 24" aqueduct concrete feed to the filter, the Rockford filters, six miles of 12" pipe, and a 5,000,000-gallon reservoir. This was a tremendous undertaking for the time, with over 400 men involved, the mixing of the concrete for the filters and reservoir, and digging and covering of the pipes done by hand. A man's work for a day was to dig, help lay, and backfill one 12' length of pipe.

The Water Works Dam

The water works dam was designed to keep a steady supply of water flowing to the filters. It had a water gathering system called a weir (a concrete box with an iron bar cover which kept out large sticks and floating debris). It was built over the end of a 24" concrete aqueduct that ran to the filters.

The Filters

The filters were two 160' x 80' covered concrete structures, separated by a 5 foot wall (above the sand). The whole structure was built half in the ground and half out. The ceiling of the filters is an amazing structural sight with a series of 2 foot square concrete pillars holding up the concrete roof. You can still see the imprint of the boards used to shape the curved ceiling. The topside of the roof was covered with soil and planted with grass. Manholes with round steel covers were spaced out in the roof. They let light in and allowed sand to be added if required. The filters were watertight and had an inlet from the river and an outlet to Owen Sound.

The bottom was covered with half round tiles laid out in a herringbone style, which gathered the water and brought it to a control well at the west end of the filters. From here the water flow was regulated. The tiles were covered with 6" of 2-inch gravel, then 6" of 1-inch gravel, then 2 lifts of smaller stone, and a top layer of two feet of sand. Altogether the filter material was 0.76 metres to 0.91 metres deep. The water ran over the top of the filter and then down through it. This system is referred to as a physical filter

Cleaning the Filter System:

The process of cleaning the water filters was labour intensive, involving washing the top layer of sand. It took six men two days to clean one filter. Three men would skim the sand, two men would run wheelbarrows to the door where another man loaded the sand into a sand washer. The washer was filled with water and the sand was pumped under 110 pounds of pressure and sprayed out a fire hose which ended in a ¾" nozzle. The clean sand was deposited on a large cement pad outside the filters and then replaced by filling wheelbarrows and dumping the sand through the manholes in the roof of the filters. This process had to be done every two to three months, less frequently in the winter. Near the end of its use, the filters had to be cleaned very two to three weeks because of degrading water quality.
