A Servicing Plan is an engineering drawing that shows the proposed layout of water, sanitary sewer, and storm sewer infrastructure for a development site. It depicts pipe sizes, invert elevations, connection points, valve and hydrant locations, manholes, and the geometry of the proposed municipal services relative to the site plan and the existing right-of-way.
In Ontario, servicing plans are required for Site Plan Approval and subdivision engineering submissions. They must be coordinated with the Functional Servicing Report and Grading Plan. Drawings are typically prepared at 1:500 or 1:250 scale and include sufficient detail for the municipality to review compliance with its design standards — including watermain loop design, fire flow hydrant coverage, sanitary gravity grades, and storm outlet geometry.
Servicing plans are sealed by a licensed P.Eng. and form part of the formal engineering submission reviewed by municipal works staff. They are later used as the basis for construction drawings and form a condition of Site Plan Agreement execution.
