Application Types

What does it mean?

Fire hydrant flow tests are conducted by DC Water at the applicant's request. The purpose of the test is to determine the hydraulic characteristics of the water distribution system at the location of their project site. This information is used by the engineer in designing the fire suppression system, calculating the size of the domestic and fire water services to the building and to size booster pump(s) if needed.

Does this apply to me?

If the project requires a domestic service connection of 3-inches in diameter or greater or has a fire demand in excess of 100 GPM, then a hydrant flow test is needed.

DC Water will require a current fire hydrant flow test be submitted with the permit application. Current means within one year of issuance of either DC Water's Water and Sewer Availability Certificate or DCRA's building permit. In accordance with NFPA code a current hydrant flow test is required to support the fire suppression system computations for the building.

Flow tests are not needed by DC Water for the design of single family houses where the fire protection flow rate is less than 100 GPM. A fire supply sufficiency letter can be obtained from DC Water for small fire services (100 GPM or less) which may satisfy DCRA requirements.

When do I apply?

It is best to apply early - during the initial design process. A fire hydrant flow test must be obtained prior to engineering the building's domestic and fire water services for the building. The mechanical/electrical/plumbing engineer uses this information to complete the meter sizing worksheet and booster pump form.

What do I need to submit?

Please have the following information in your request package:

  1. A letter, on company letterhead, requesting a fire hydrant flow test. Please include an email address and/or fax number of the person(s) that you would like the results of the flow test sent.
  2. A check or money order made payable to DC Water in the amount of $320.

Where do I go and apply?

Please mail or drop off the application to
Permit Operations Department
Attn: Fire Hydrant Flow Test Request
1385 Canal Street SE,
Washington, DC 20003

How long will it take?

30 days depending upon weather and emergency work load.

Please note that during winter months (when the average temperature is below 40 degrees Fahrenheit) hydrant flow tests are generally not performed due to potential risk of icing and will generally take more than 30 days to be processed.

What do I Receive?

You will receive a report that includes the static and residual pressure of the main and the flow rate at each hydrant. Click here for a sample fire hydrant flow test report. The report will be emailed or faxed to the attention of the person on the request letter.

Related Activities:

For larger projects (NFPA fire demand exceeds 100 GPM), the next activity following the hydrant flow test is typically submission of the preliminary site plan to DC Water for review and subsequent approval.

For more Info, call:

Permit Operations Department at 202-646-8600

Regulatory Info

DC Building Code and NFPA governing the fire suppression system design require a current hydrant flow test in additional to the requirement by DC Water.

Additional Information:

On occasion there are hydrant flow test that have been performed on the same hydrants that you are requesting (nearby projects that you see are under construction) that may be applicable for your project. If the flow data is current it can be used in lieu of a new hydrant flow test.

These results can be obtained by calling the Permit Operations Department at 202-646-8600. Please have the address of the adjacent site that you think may have the recent flow test results.

Significant Categorical Industrial User Wastewater Discharge Permit

This type of permit is issued to Industrial Users that are subject to Categorical Pretreatment Standards, and at any time discharge more than 100 gallons per day (gpd) of total categorical wastewater excluding sanitary, non-contact cooling and boiler blowdown wastewater unless specifically included in the pretreatment standard.

Significant Non-Categorical Industrial User Wastewater Discharge Permit 

This type of permit is issued to significant industrial users that are not subject to Categorical Pretreatment Standards, and discharge an average of 25,000 gallons per day or more of process wastewater to the District's wastewater system (excluding sanitary, non-contact cooling and boiler blowdown wastewater), or, users who contribute more than five percent (5%) hydraulic or organic loading to the Blue Plains AWTP, or DC Water has determined that the Industrial User has a reasonable potential to adversely affect the operation of the Blue Plains AWTP, violate any pretreatment standard or requirement, harm the environment, or cause a threat to wastewater utility personnel. Users discharging 25,000 gpd or more of contaminated non-wastewater flow (e.g., stormwater, construction dewatering, groundwater sump discharges, etc.) for more than six months may be issued this type of permit.

Non-Significant Categorical Industrial User Wastewater Discharge Permit

This type of permit is issued to Industrial Users that are subject to Categorical Pretreatment Standards that never discharge more than 100 gpd of categorical wastewater (excluding sanitary, non-contact cooling and boiler blowdown wastewater, unless specifically included in the pretreatment standard), and meet the three (3) conditions provided in the definition for Non-Significant Categorical Industrial User in D.C . Official Code § 8-105.02(11)(B).

Non-Significant Non-Categorical Industrial User Wastewater Discharge Permit 

This type of permit is issued to minor industrial/commercial businesses and government agencies that have less than 25,000 gallons per day of process flow and are specifically designated by DC Water due to the type of business, characteristics of the discharge, or presence of pretreatment facilities. Businesses with contaminated non-wastewater flow may also be issued this type of permit if discharging less than 25,000 gpd.

These permits are valid for four years.

What are DC Water's fees for this?

Industrial Permitting Fees & Industrial User Annual Compliance Fees Apply.

Industrial permitting and annual compliance fees became effective October 1, 2012, to cover pretreatment program operating costs including permit preparation, sampling, inspections, and report review. Please see the DC Water fee schedule page for additional information about these fees. An invoice will be issued upon receipt of the permit application.

Related Activities:

Permitted facilities that are identified as significant industrial users are inspected and sampled on an annual basis, at a minimum, by DC Water, to help ensure compliance with local regulations. Those facilities that are designated as non-significant Industrial users may be inspected and sampled less frequently. Non-permitted facilities may also be inspected and sampled at any time by DC Water and must still conform to the wastewater discharge regulations.

Additional Info

Industrial Users may also be required to conduct self-monitoring. All compliance monitoring must be reported on DC Water's Periodic Compliance Report Form and be signed and certified by the Industrial User.

For more Info, call:

DC Water Permit Operations Department at 202-646-8600.

What does it mean?

DC Water allows residents, businesses, and government agencies to discharge stormwater, groundwater, and surface water runoff from construction/dewatering projects or other temporary water discharges (e.g., power wash runoff, hydro-demolition wastewater, etc.) to the District's wastewater system on a case-by-case basis.

However, uncontaminated non-wastewater flows (e.g., stormwater, groundwater, surface water runoff, etc.) may only be discharged to the combined sewer system, storm sewer, or to an outfall that discharges to a natural stream/river. It is illegal to discharge uncontaminated non-wastewater flows, including groundwater to the separate sanitary sewer system.

The District's local limit discharge standards apply to all temporary dischargers. DC Water currently has no numerical standards for volatile organics, however, specific prohibitions may apply that prohibit the discharge if it contains volatile organics in amounts that may create a fire or explosion either alone or by interaction with other substances or result in the presence of toxic, noxious, or malodorous liquids, solids, gases, vapors, or fumes within the District's wastewater system which alone or in interaction with other wastes, are capable of creating a public nuisance or hazard to humans or animals, are sufficient to cause acute worker health and safety problems, or are sufficient to cause interference or pass-through. In order to determine if volatile organics require pretreatment and to determine if a non-wastewater flow is considered contaminated, DC Water compares water quality data to published literature values in EPA's Guidance to Protect POTW Workers from Toxic and Reactive Gases and Vapors and EPA's Local Limits Development Guidance.

What does "uncontaminated" mean

Uncontaminated means the discharge (prior to treatment) does not exceed the District's pretreatment standards: local limit discharge standards or prohibited discharge standards.

Does this apply to me?

Applicants wanting to discharge non-wastewater flows (e.g., stormwater, groundwater or surface runoff) or other temporary discharges to the District's wastewater system must submit a Temporary Discharge Authorization (TDA) Permit Application to the Pretreatment Program Manager. If the volume of the discharge is greater than 25,000 gallons per day (gpd) and the duration of the discharge is greater than six months, the applicant may be requested to submit an Industrial User Wastewater Discharge Permit application.

If the groundwater is not contaminated and the discharge location is near a separate storm sewer system (i.e., not part of the combined sewer system), then the applicant may be required to contact the DC Department of Energy & Environment to direct the discharge to the storm sewer. To determine if the project is in a separate storm sewer area contact DC Water's Permit Operations at 202-646-8600.

If the groundwater is to be discharged to the combined sewer system, then DC Water will determine the conditions under which a TDA Permit will be issued and whether metering and fees are required.

When do I apply?

Once you are aware that you have stormwater, groundwater, or surface water runoff, or other water that must be discharged on a temporary basis, you should commence the process to determine whether you need a permit.

What do I need to submit?

  • Temporary Discharge Authorization Permit Application (no application fee)
  • Chemical analysis of the effluent (e.g., groundwater or other water, if available)
  • Copy of any engineering plans/documents with information on dewatering requirements and site contamination (soil and groundwater) such as a dewatering plan, geotechnical report, and/or site assessment
  • Site map of proposed discharge location

Where do I go and apply?

The application package shall be mailed or delivered to the

DC Water
Department of Wastewater Treatment
Pretreatment Program
5000 Overlook Ave., SW
Washington, D.C. 20032

Telephone: 202-787-4177

For expeditious processing, a copy of the application package may also be emailed to pretreatment@dcwater.com with a hard copy to follow in the mail.

How long will it take?

Approximately 2 weeks

What do I Receive?

A Temporary Discharge Authorization (TDA) Permit is issued and the permit is valid for up to two years. A permit may be extended by written request if within the two year permit term.

Per the District of Columbia Building Code utilities are considered available if a residential lot is within 100-feet; a commercial lot is within 250-feet measured along the centerline of a street or public way abutting the lot.

This letter only advises you that water and sewer mains are available to service this project. This is not an approval to connect to these facilities or a certification that there is adequate capacity in these mains to serve the proposed development. A Water and Sewer Availability Certificate will be issued after the approval of the project plans and the payment of all the appropriate fees.

Does this apply to me?

Your financer will ask for this if it is required.
