Mill Creek Municipal Drain
Project Description
The original Mill Creek Municipal Drain was constructed in 1956. At that time, the drain terminated at Hwy. 17 and flowed a further 2km through a natural watercourse to its outlet at the Ottawa River. Subsequent years saw significant increases in agricultural activity including clearing of previously forested lands, increased tile drainage, urban development, and the addition of contributing drains.
Increased pressures from upstream drainage in conjunction with poor underlying soil conditions resulted in a significant slope failure on the natural water course section within the village of L’Orignal.
The Township of Champlain tasked Robinson Consultants Inc. with addressing the slope failure as Emergency Work under Section 124 of the Ontario Drainage Act, R.S.O. 1990, and ultimately with full modification and improvement of the Mill Creek Municipal Drain under Section 78 of the Act to incorporate the emergency work and make necessary adjustments for the remainder of the drain. Robinson Consultants Inc. successfully petitioned the Ontario Ministry of Agriculture Food and Rural Affairs for permission to complete the Emergency Work.
Design for the failure area included geotechnical review of the slope failure and adjacent area, drone level LiDAR survey of the failure (conditions were not stable for a standard survey to be completed) and the implementation of specialized geotechnical design incorporating a ballast feature with slope flattening and standard rock protection.
Following the completion of the emergency work, Robinson Consultants Inc. was tasked with preparing an Engineer’s Report for improvement and modification for the full extent of the drain, including incorporating the emergency work. Ensuring sufficient outlet included incorporating as a municipal drain the remainder of the natural watercourse to the outlet at the Ottawa River. Improvements included permanent sediment and erosion control with some deepening and widening of locations restricting flow. Special consideration was required to address the concerns of environmental agencies including the Department of Fisheries and Oceans, Ministry of Natural Resources (acting as the Conservation Authority for this area as it is outside of the jurisdiction of a Conservation Authority), and the Ministry of Environment Conservation and Parks for the protection of Endangered Species.
Chenier-Jeaurond Municipal Drain
Project Description
The Chenier-Jeaurond Municipal Drain is a new drain, petitioned by local property owners Under Section 4 of the Ontario Drainage Act, R.S.O., 1990. Property owners were concerned that the existing watercourse comprised of an Award Drain (constructed in the late 1800s under a predecessor to the Drainage Act), private ditches, and natural wet areas did not provide sufficient outlet to protect crops during the growing season. Improvement and incorporation as a municipal drain was required to accommodate modern agricultural practices and allow for sufficient outlet and future maintenance.
The Township of North Glengarry appointed Robinson Consultants Inc. under Section 8 of the Ontario Drainage Act, R.S.O. 1990, as the Drainage Engineer to prepare a report for the future construction of the Chenier-Jeaurond Municipal Drain.
Design included the deepening and widening of the existing watercourse, incorporation as a municipal drain and establishing permanent sediment and erosion control features. Provisions were made for private farm crossings that accommodated modern farming equipment and sufficient outlet for surface and subsurface (tile) drainage. Special consideration was given to address the concerns of environmental agencies including the Department of Fisheries and Oceans, Raisin Region Conservation Authority, and the Ministry of Natural Resources.

Municipal Drains Engineering Solutions
Municipal drains have been a fixture of Ontario's rural infrastructure since the 19th century and are vital components of our water and drainage systems. Without them, many areas of the province would be subjected to regular flooding, damage to crops, and increased public health risks.
Municipal drains are created under the authority of the Drainage Act. Under the Drainage Act, an engineer is customarily called upon to "act" for the purpose of preparing a report for a municipal drain. Municipal drains are initiated by a Petition from landowners. New Reports may also be indicated by Municipal Council for repair or improvement of an existing municipal drain or to update the report to accommodate a change in land use. The report of an Engineer is also required to "abandon" a section of drain when it is no longer required.
What We Provide
Our Drainage Engineers have considerable experience preparing Engineer's Reports in accordance with the Drainage Act, R.S.O. 1990, c. D.17, having completed over 150 municipal drain projects under the Act.
Robinson Consultants offers a range of comprehensive municipal drainage engineering services including:
- Preparation of Engineering Reports
- Drainage Assessment
- Drainage Allowance
- Emergency Work
- Petition Drains
- Compliance with Drainage Act
- Drainage Superintendent Services
Monahan Creek Municipal Drain
Project Description
The original Monahan Creek Municipal Drain was constructed in 1968. At that time, the drain served a largely rural/agricultural area. Subsequent years saw significant urban development in the upper reaches of the drain which included abandonment, improvements, sections incorporated as storm sewers, and the development of an urban constructed wetland stormwater management facility. However, during this period the downstream end of the drain and outlet capacity remained unchanged.
The City of Ottawa appointed Robinson Consultants Inc. under Section 78 of the Ontario Drainage Act, R.S.O. 1990, as the Drainage Engineer for modification and improvement of the Monahan Creek Municipal Drain.
Initial review indicated that the original 1968 design could no longer provide sufficient outlet for the growing urban infrastructure.
Design included the deepening and widening of the drain and establishing permanent sediment and erosion control features as well as special design for the replacement of six low-level crossings. The design incorporated provisions to address the concerns of environmental agencies including the Department of Fisheries and Oceans, Rideau Valley Conservation Authority, and the Ministry of Natural Resources. Best management practices were developed and successfully implemented to allow for authorization, permitting, and the protection of endangered species.
