Water and Sewer Availability Letter

What does it mean?

Some financers require that a Water and Sewer Availability Letter be provided prior to the financer approving a loan. This letter identifies whether there is water and sewer available to the project site and which lines are not available for connection. 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.

When do I apply?

DC Water Breaks Ground on Piney Branch Tunnel, Final Phase of DC Clean Rivers Project

Today, DC Water broke ground on the Piney Branch Tunnel, the final major tunnel in our Clean Rivers Project. This work will help keep sewage and trash out of local waterways and make Rock Creek, the Potomac River, and the Chesapeake Bay cleaner for our community.

When we finish the Piney Branch Tunnel, it will hold at least 4.2 million gallons of rainwater and wastewater during heavy storms. Instead of overflowing into Piney Branch, that water will go to the Blue Plains Water Resource Recovery Facility, where it will be treated.
