The online form for invoices, is only for category one and category two requests.

Category I (Re-use of the existing service connections with no significant impact):

The alteration/ renovation work being proposed is fairly insignificant and DC Water (DCW) can approve reuse of the existing service based on net increase in water supply fixture units. You will need to upload Water Supply Fixture Units (WSFU) worksheet, plumbing plans and a riser diagram showing existing/ proposed fixtures in ProjectDox. These can be in the supplemental documents if you so choose. To fill out these documents correctly you must also know the existing service pipe size to determine if total net increase in water supply fixture unit is within threshold limit or not.

Applies to:

1. Reuse of the existing water and sewer service connections only.
2. Addition, alteration, or repair permit only.
3. Residential building only.
4. No existing/ proposed fire sprinkler service to the building.

Steps:

1. Determine the existing water service connection size by filling-out a ‘request for information for meter sizing worksheet’ form. The form is available at https://www.dcwater.com/design-standards-and-forms.
2. Fill out a ‘Water Supply Fixture Units Worksheet’ (available on the DCW website). The water supply fixture unit values are based on net increase in fixture values from the existing condition.
3. If the existing water service connection size is adequate, upload WSFU worksheet, plumbing plans, and riser diagram in ProjectDox for a review.
4. The application can be approved if total net increase in fixture values is within the threshold limit of the existing water service connection size.
5. If the existing water service connection size is not adequate, follow steps in Category II.

Category II (Re-use of the existing service connections with significant impact):

The alteration/ renovation work proposed exceeds the limits of the Category I criteria but the existing service may still be adequate for the proposed final building. Please add complete meter sizing worksheet, plumbing plans and riser diagram showing existing/ proposed fixtures in ProjectDox identifying all WSFU and fire sprinkler demand value (if applicable) that will be served by the existing water service connection and meter. You need to fill-out ‘request for information for meter sizing worksheet’ in order to fill out complete meter sizing worksheet. If the existing water service pipe and meter are adequately sized for the total water demand, DC Water can review and approve in ProjectDox.

Applies to:

1. Reuse of the existing water and sewer service connections only.
2. Addition, alteration, or repair permit only.
3. Residential or commercial building.

Steps:

1. Fill-out a ‘request for information for meter sizing worksheet’ form.  The form is available at https://www.dcwater.com/design-standards-and-forms.
2. Fill-out complete meter sizing worksheet (small or large as applicable).  The meter sizing worksheet is available on the DCW website.
3. If the existing water service pipe is adequate, upload complete meter sizing worksheet, plumbing plans, and riser diagram in ProjectDox.
4. The application can be approved if the reuse of existing water service connection and meter sizes meet the current DC Water standards.
5. If the existing water service pipe size is not adequate, follow steps in Category III.

Category III (new water and/ or sewer service connection):

The work proposed will require some new connections to the public water or sewer system. In this case you will need to make a separate submission to DC Water to have your plans reviewed and approved. The review must be done in the DC Water system so that work orders and account information can be generated. The directions and forms can be found on DC Water’s website.

Applies to:

1. All applications that need a new water/ sewer service connection.

Steps:

1. Visit DC Water permit operations website and determine application type based on the proposed size of water service connection and property type.

2. Submit appropriate plans, submission checklist, & log slip.
