A Functional Servicing Report, or FSR, explains at a functional level how a proposed development can be supplied with water and served by sanitary and storm systems. It gives municipal reviewers a coordinated basis for deciding whether the servicing concept is feasible before detailed design advances.
What the report normally covers
An FSR typically describes the existing site, the proposed land use and the municipal infrastructure available near the property. It estimates water demand, fire-flow requirements and sanitary sewage flows; identifies proposed connection points; and explains the storm drainage and stormwater management approach.
The report may also assess downstream or local system capacity, required easements, external works, phasing and approvals from another agency. Supporting plans commonly show existing and proposed services, grading directions, drainage areas and preliminary control measures. The exact scope comes from municipal standards and pre-consultation comments, not from a single province-wide template.
Why coordination matters
Servicing is connected to the site plan. Building locations, entrances, fire routes, landscape areas and accessible paths can all affect pipe alignments and grades. A park or recreation site can add washrooms, drinking fountains, splash-pad equipment, irrigation demands and stormwater facilities, each with different water, sanitary or drainage implications.
That is why an FSR should be developed alongside the site plan, architectural information and available survey data. Bous Engineering’s Functional Servicing Report service focuses on that coordinated submission package.

Key takeaway
An FSR is a feasibility and approvals document, not a construction drawing set. It should clearly demonstrate the proposed servicing strategy, its assumptions and the project-specific issues that still require detailed design or confirmation.
