From2010topresent,DCWater committed more than $2.8 billion for engineering and construction projects in the areas of:

Blue Plains upgrades andimprovements

Combined sewer overflow (CSO), outfall rehabilitation, and pumping station projects

Sanitary pumping facilities and trunk sewer upgrades

Water distribution and water facility upgrades

Past Engineering and Construction Dollars Committed

Water main and sewer break repair along Spring Place, in Washington, DC.

Our Capital Improvement Program (CIP) for the next 10 years is valued at $3.8 billion, and over the next 20 years, $8.4 billion.

we will work with you
We Will Work withyou!

Over the last 3 years (FY 2011 – FY 2013), DC Water has awarded:

71 Design, Construction, and CM contracts with an award value of $2.01 billion

Of this total, over 33% (or $674 million) was awarded to:

Minority Business Enterprises (MBEs), Women Business Enterprises (WBEs), Local Small Business Enterprises (LSBEs), and Certified Business Enterprises (CBEs)

MBEs and WBEs have been awarded $584 million

LSBEs and CBEs have been awarded $90 million

For Design-Build contracts, the prime firms indicated that they will continue to pursue opportunities to exceed the goals of:

MBE = 32% and WBE = 6% for construction contracts

MBE = 28% and WBE = 4% for A/E contracts

mbe and wbe requirements
MBE and WBE Requirements

DC Water’s MBE and WBE Fair Share Objectives are:

Objectives are based on goals established by EPA Region 3: DC, DE, MD, PA, VA, & WV

DC Water’s policy is to meet or exceed EPA objectives for MBE and WBE participation in prominent and leadership roles

Note that some of the projects discussed today may or may not have EPA small business goals. DC Water continues to encourage the use of small businesses.
