1. Sewer System Geodatabase Adding line and point features

2. Oleander Public Works Dept. In this exercise we will design feature classes to store data for a sewer system We are going to use domain, subtype, and topology in this database too Sewer systems are made of pipes (linear features) to carry wastewater to treatment plants The pipes are connected to make a network Pipes have many attributes, e.g., size, material, year installed Print the design form from the DVD

3. Design In this project, because the pipes will be put together in a network, we need to set up a feature dataset Go to: C:\ESRIPress\GIST3\Data in your computer and download a clean copy of the GDB Design Forms to be used for this project Open the Excel version of the design forms Save (and/or print) them in a directory of your choice so that you can fill them in – Name it: GDB Design Forms_tutorial_1_2

4. Utility Data Database Open the GDB (Geodatabase) worksheet Name the database as: Utility Data Create a new dataset: Wasterwater Create a new feature class: Sewer Lines – Type: L; name: SewerLines, Alias: Sewer Lines – Now let’s define the fields for the SewerLines table (feature class)

5. Tables Worksheet Name the feature class/table as Sewerlines Define the following fields (attributes): – PipeSize:short integer (SI), Pipe Size, NN – Material:Text, Pipe Material, NN – YearBuiltLong Integer (LI), Year Built, Null – DescriptionText, Owner, NN

6. Tables worksheet Feature class orNullsDefaultDomain name or table nameField nameField typeAlias(Y/N)valuesubtype field (S) or (D) SewerLinesPipeSizeSIPipe SizeNo MaterialTextPipe MaterialNo YearBuiltLIYear BuiltYes DescriptionTextOwnerNo

7. Data Integrity with Domain Pipes come in different sizes (6”-12”) – We do not want size to be entered wrongly – Pipes > 12” are interceptors Owned by a regional utility (not by the Public Works) – Since the size increases by 2”, we need to create coded values – Go to the Domains worksheet

8. Domain … In the Domain worksheet add the following SewerPipeSize, Sewer Pipe Size, SI, coded values, and add the following in the gray area: 66” 88” 1010” 1212”

9. Domains worksheet Coded values / Range Domain nameDescriptionField typeDomain typeCode (Min) Desc (Max) SewerPipeSize SICoded values6 6" 8 8" 10 10" 12 12" Add the domain to the Tables worksheet call it: SewerPipSize with a (D) before it to represent domain

10. Data Integrity with Subtype Make a new feature class/table in the geodatabase worksheet: L, Interceptors, Interceptors Add the table to the Tables worksheet: The interceptor do not have regular size and material, we do not need a domain Copy properties of the SewerLines for the Interceptors However, we want to define the pipe material as a subtype Since subtypes must always be integer, we change the field type for the Material as SI See next slide

11.

12. Subtype for pipe material Now, define the subtype for the pipelines in the Subtypes worksheet Do this for: P.V.C (Polyvinyl chloride) HDPE (High-density polyethylene) DI (ductile iron) See next slide for the entries!

14. Add Point features Manholes are points along the sewer lines Cleanouts are also access points at the end of the pipe line to cleanout clogs These points coincide with the pipes, i.e., they lie on the pipe lines and are connected to the pipes Because of this, they must reside with the pipelines in the same feature dataset

15. Attributes of the points The manholes and cleanouts have several attributes In the GDB worksheet, write a new point feature called SewerFixtures of type PNT and Sewer Fixture description Now, go to the Tables worksheet and add the SewerFixtures as a new layer (class/table), and add its attributes Add the SewerFixType for the subtype of the Fixture type – See next slide

17. Create the SewerFixType Subtype Go to the Subtypes worksheet Add the SewerFixType subtype; with code 1 for manhole and 2 for cleanout Interceptors also have fixture – Add InterceptorFix to the GDB worksheet with type PNT and Interceptor Fixture description – Add InterceptorFix table to the Tables worksheet – See next slide
