#pipe alignment

Selecting the right pipe alignment is very important in a stormwater drainage projects.

Sometimes it may be desirable to cross over an existing drainage line. A consideration should always be given to connect drainage lines.

Important consideration is also avoiding obstacles like power poles. Ensure that an adequate offset is maintained for the depth of the pipe from the pole. The Power Authority should be consulted and asked to endorse the works so that any construction problems cab be resolved smoothly.

Once services are proved (located and measured on site), their accurate location should be shown on the alignment plan, Longitudinal section and cross-sections. This will help highlight the location of the services so that the contractor for the works re-confirms their location on site. Any discrepancy of the information shown on the design plans will need to be reported back to the designer for evaluation.
