Not Documenting Design Decisions

Keep a record of your design decisions, including the sections of the manual you relied upon. This will help you justify your choices and demonstrate compliance during reviews.

Neglecting Site-Specific Conditions

The manual provides general guidelines, but it's important to consider site-specific conditions, such as soil type, topography, and existing infrastructure. Adapt your designs to account for these factors.

Ignoring Manufacturer Specifications

The manual often references manufacturer specifications for materials and equipment. Don't overlook these specifications, as they provide critical information about product performance and installation requirements.

Assuming Compliance Based on Past Projects

Just because a design was approved in the past doesn't mean it automatically complies with the current manual. Always review your designs against the latest version of the manual.

Not Coordinating with Other Utilities

Water and wastewater projects often involve coordination with other utilities, such as gas, electric, and telecommunications. Make sure to coordinate your designs with these utilities to avoid conflicts and ensure a smooth construction process.
