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.

6. We Will Work with you!
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

7. 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

9. Blue Plains Construction by Diala Dandach

10. Wastewater Services at Blue Plains
Planning, design, and construction of projects for rehabilitation, upgrade, or implementation of new facilities 10

11. Wastewater Services at Blue Plains: Major Projects
Facility upgrades as necessary to comply with future regulatory limits for Total Nitrogen (TN) and Wet Weather
By January 1, 2015: Reduce plant nitrogen discharge (TN) from 8,467,200 to 4,377,580 pounds per year:
Mainly accomplished by the “Enhanced Nitrogen Removal Facility” project
Also includes ENR-North (secondary treatment upgrades)
Filtrate Treatment Facility (treatment of filtrate from dewatering after new digestion process)
By March 23, 2018: Pump and process through an Enhanced Clarification Facility up to 225 MGD of combined sewage captured in the Blue Plains Tunnel

12. Wastewater Services at Blue Plains: Major Projects
Facility upgrades and processes that have a payback
Biosolids Management Plan (Digesters, Cambi, Dewatering Facility) reduces sludge volume, produces a Class A product, produces electricity to offset 1/3 of plant’s electrical load
Digesters under construction.
Fully utilized biosolids site.
CambiTM reactors.
