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 contractsMBE = 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

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

CambiTM reactors.

Digesters under construction.

Fully utilized biosolids site.

Smaller Projects DC Water is working through

one of the most ambitious capital upgrade programs in the history of the utility

Now moving into a phase of rehabilitating and upgrading its existing facilities

No new greenfield projects Upgrades consist of smaller

projects to existing process areas within Blue Plains

Focus is on systems (primary treatment, odor control, fiber optics, flood wall)
