Rural Ditches and Drainage

Statistic card: about $670 spent per kilometre of ditch per year, across 5,400 kilometres. The money went up, the delivery model did not.

Rural Ottawa / ditches and drainage

The money has gone up. The delivery model has not.

Ottawa maintains roughly 5,400 kilometres of roadside ditch. Drainage determines whether farmland drains, whether basements stay dry, whether road shoulders hold, and whether a road ices over in the spring.

Following the 2024 Rural Summit, the city doubled the ditching and drainage budget, adding $1.8 million for a total of $3.6 million. Total ditching and drainage investment is projected to reach $5.6 million by 2027, and a new stormwater fee structure replaces the stormwater charge on rural tax bills with a levy dedicated to rural drainage maintenance.

That is real money and this campaign is not going to pretend otherwise. The problem is what the money buys.

The gap: the category with no clock

At $3.6 million across 5,400 kilometres, the city is spending roughly $670 per kilometre of ditch per year. The constraint on that spending is not only the budget line. It is crew hours, equipment availability, and the time it takes to move equipment to a rural work site. The city’s own 2026 ditch work plan identifies the same constraint: it lists additional staffing, contracted service support, and equipment procurement among the changes required to deliver the increased budget.

The prioritization framework has a gap. Priority A, blocked drainage causing flooding and an immediate safety hazard, is targeted for completion within four hours. Priority B, partial blockage causing intermittent backup, is targeted within 30 days. Priority C, drainage system deterioration with no immediate hazard, is added to the ditch maintenance list and completed “as soon as practicable.”

Priority C is where most rural ditch deterioration sits, and it is the only category without a service standard. Work is identified through service requests, routine visual inspection, and spring flooding response, which means the system is largely request-driven: a ditch is maintained after a resident notices a problem and reports it.

There is a second source of capacity available in the rural area that the city does not systematically use. Ottawa’s rural landowners and farm operators already own excavators, tractors, mowers, and float trailers, and already operate them within a few kilometres of the ditches in question. Their equipment is idle in exactly the seasonal windows when ditching is done. A local operator mobilizes to a rural work site in minutes; a centrally dispatched crew spends a meaningful share of the working day travelling to it and back.

This is not a novel arrangement. Ontario municipalities routinely deliver ditching, brushing, grading, and roadside maintenance through contracted local operators alongside in-house crews. What Ottawa lacks is the procurement instrument that would let it buy that capacity at scale.

The commitments

Set a service standard for Priority C and report against it.

Assign Priority C ditch maintenance a target completion window and publish performance against it quarterly, by ward. “As soon as practicable” is not a standard, cannot be measured, and cannot be held to account. Every other priority level in the system has a number attached to it.

Establish a rural maintenance roster at published unit rates.

Create a qualified supplier roster for rural roadside maintenance, open to any operator who meets the qualification, with unit rates published in advance: per metre of ditch cleaned to specification, per kilometre of brushing, per culvert flushed. Work is issued as call-ups against the roster rather than through a separate tender for each segment. Operators bid to maintain defined segments within a service radius of their base of operations, so mobilization time is minimal and the same operator returns to the same segments year over year, which builds local knowledge of where the water actually goes.

Scale qualification and insurance to the size of the contract.

The single largest barrier to a local operator bidding on city work is an insurance, bonding, and prequalification package written for a multi-million dollar contractor. Tier those requirements to contract value, publish the tiers, and run an annual qualification session in the rural wards. A roster nobody local can qualify for delivers nothing.

Protect the standard, and the integrity of the arrangement.

Contracted ditch work is performed to the city’s grade and slope specification, inspected and signed off by a city inspector before payment, and subject to the same Ditch Alteration Policy, Conservation Authority permits, and in-water timing windows as city crews. Municipal drains under the Drainage Act remain the responsibility of the drainage superintendent and are outside the roster. Where a contracted segment abuts the operator’s own property, the arrangement is disclosed on the public roster, the segment is flagged, and it is audited at a higher rate than the balance of the roster. Unit rates are public. Roster membership is published.

This is one part of the Lawson plan for rural Ottawa.

We’ve got a lot of work to do.

Ottawa deserves better.
