If you need to submit drawings with an adoption of sewers submission, you'll find our guidelines really useful.
Take a look below to see the Do's and Don'ts when it comes to submitting drawings.
• Ensure prospective abandoned public sewers remain black and are shown cross-hatched.
• Ensure all other items on the drawing remain black so they don't detract from the clarity of the public sewer proposals.
• Denote cover levels at low level points on the layout of private drainage so that flooding checks can be undertaken against surcharge levels on the adoptable system.
• Colour existing sewers as these are already public sewers.
• Colour gullies.
• Colour sewer lengths serving highway drainage only.
• Colour watercourses.
Download our PDFs to make sure that you're within the guidelines:
• The proposed sewers should indicate pipe material, diameter, and direction of flow.
• All laterals should indicate pipe size, direction of flow and gradient.
• Foul water laterals should be coloured brown, these should be coloured from demarcation chamber to demarcation chamber or demarcation chamber to manhole.
• Surface water laterals should be coloured blue
• Diverted sewers and manholes should be coloured purple.
• Abandoned sewers should be coloured green with crosses through.
