Barrie Drainage Design

Why Choose Barrie Drainage Design?

Effective drainage is essential for protecting property, maintaining structural integrity and preventing costly water damage. In Barrie, the climate brings heavy snowfall, spring melt and occasional intense rainstormsconditions that demand a wellengineered drainage system. Our team combines local knowledge with industryleading engineering practices to deliver solutions that are reliable, sustainable and compliant with Ontario regulations.

Our Services

We offer a full spectrum of drainage design services, tailoring each project to the unique needs of the client and site.

1. Site Evaluation & Hydrologic Analysis

Our engineers conduct detailed topographic surveys, soil investigations and rainfall data analysis to determine water flow patterns and potential problem areas.

2. Stormwater Management Design

From detention ponds to underground storage tanks, we design stormwater systems that meet the requirements of the Barrie Conservation Authority and minimize downstream impacts.

3. SubSurface Drainage Systems

We design French drains, perforated pipe networks, and buildingintegrated drainage solutions that safely convey water away from foundations and basements.

4. Roadway & Pavement Drainage

Our designs include curbinlets, catch basins, and slope grading to keep roadways safe and serviceable throughout the year.

5. Erosion Control & Slope Stabilization

We incorporate retaining structures, vegetation reinforcement and geotextiles to protect vulnerable slopes from erosion during melt and heavy rain events.

6. Permit Preparation & Regulatory Support

We prepare all required documentation for municipal and provincial approvals, ensuring a smooth permitting process.

Our Design Process

Transparent communication and a systematic approach are at the heart of every project.

1. Initial Consultation Discuss goals, budget, timeline and site constraints.
2. Data Collection Gather surveys, GIS data, soil reports and historic weather records.
3. Concept Development Produce preliminary layout options and evaluate costeffectiveness.
4. Detailed Engineering Create hydraulic calculations, hydraulic grade lines, and constructionready drawings.
5. Stakeholder Review Present designs to owners, municipal officials and any affected neighbours.
6. Final Documentation Deliver complete set of CAD drawings, specifications and permit packages.
7. Construction Support Provide onsite clarification, field inspection and asbuilt documentation if required.

Case Studies

Residential Basement Waterproofing 2023

Location: A lakefront home in the south end of Barrie.

Challenge: Persistent basement moisture due to high water table and inadequate French drains.

Solution: Designed a perimeter French drain with a perforated pipe, filter fabric and a sump pump system sized for a 150mm/hr design storm. Integrated a daylight outlet to a newly constructed dry well.

Result: Basement moisture reduced by 95% within the first season; homeowner avoided costly interior repairs.

Commercial Parking Lot 2022

Location: A 12,000sqm retail complex near the Highway400 corridor.

Challenge: Frequent ponding after spring melt causing slip hazards and damage to paving.

Solution: Implemented a series of curbed inlet catch basins linked to an underground detention vault sized for a 25year storm event. Added a vegetated swale to treat runoff before discharge to the municipal sewer.

Result: No reported ponding incidents postconstruction; the project earned a local sustainability award.

Municipal Roadway Rehabilitation 2021

Location: Barries downtown arterial road undergoing a resurfacing program.

Challenge: Existing storm drains were undersized, leading to flooding after heavy rainfalls.

Solution: Reengineered the curbinlet layout and replaced 150mm diameter pipes with 225mm highcapacity culverts. Designed a grading plan that directs runoff to a newly installed retention basin.

Result: Flooding eliminated, and the roads service life extended by an estimated 20 years.
