CAPITAL IMPROVEMENT PROGRAM OVERVIEW
District of Columbia Water and Sewer Authority's (DC WASA / Authority) ten-year capital improvement program (ClP) totals $3.8
billion (cash disbursements basis), approximately $600 million more than last year's plan. As mentioned in Section I and discussed
in more detail later throughout this document, the major drivers of this increase are in the Combined Sewer Overflow-Long Term
Control Plan (CSO-LTCP) and the Water and Sewer Service Areas of approximately $300 million each. The increases in the CSO-
LTCP are driven by the updated cost estimates from the recently completed facility plan for this project, and approximately $100
million worth of projects that were transfered from the Total Nitrogen Removal Program (under the Wastewater Service Area). The
higher costs in the Water and Sewer Service Areas, after an offsetting decrease in the Lead Service Replacement Program
disbursements of approximately $80.3 million, were a result of including several high priority water and sewer facility improvement
projects and a service life restoration program in the current ClP. Also included in the proposed CIP is $75.6 million for the Land-Use
Facility Plan that provides for a new Warehouse at Blue Plains, Office facilities for the new CSO-LTCP project team, and relocation of
Customer Services personnel, among others.
lncluded within the proposed ten-year CIP is implementation of the Biosolids Management Plan including the costs of construction of
the Combine Heat and Power plant (CHP) and Digesters with estimated completion in FY 2014. An interim method of financing the
digesters has been utilized in this plan for two primary reasons: first, to mitigate the impact of such a large capital addition on our
customer's rates; and second, to match the financing costs with the benefits that will accrue to the Authority over the life of these
facilities.
The following sections summarize major projects and changes in each service area, with additional details for each project included
in each service area section. Please note that all dollar amounts are presented on a project lifetime basis, except where noted
otherwise.
WASTEWATER TREATMENT
The lifetime budget for the Wastewater Treatment Service Area is $2.6 billion dollars, an increase of $147.2 million from last year's
budget. This net increase reflects the transfer of $100 million from the Blue Plains Total Nitrogen Removal Plan to the CSO LTCP.
Other major costs drivers in this area include: Electrical Power Systems Switch Gear Upgrades ($29.0 million); improvements to the
Solid Processing Building and Dewatered Sludge Loading Facility ($12.2 million); Secondary Treatment Upgrades for the Total
Nitrogen Program ($59.9 million); Blue Plains Tunnel Dewatering Pump Station ($27.0 million); and, Bolling Overflow and Diversion
Project ($2S.0 million).
Also, this Area reflects the implementation of the Biosolids Management Plan including the costs of construction of the CHP and
Digesters with estimated completion in FY 2014. The benefits of this plan include producing a Class A biosolids product which can be
