Overview
Markham's Builder Tip No. 103, dated January 1, 2025, on the sewer piping inspection for infill homes, filed with the City's housing tips under the 2024 Ontario Building Code; the City's New Home Report refers to it for sewer connections. It quotes the roles of chief building officials and builders, Sentence 7.3.6.1.(5) on ball tests and Article 7.4.10.8. on hydraulic loads. Its objective lists the six items a plan and cross-section show, from invert elevations to slope, and three sample sheets carry a Sanitary Sewer Plan and Sanitary Sewer Cross-Section.
