42 percent of the Commission’s 2010 direct expense budget was for the Operations Division. Of the Operations Division’s direct expense budget, about $14 million was for sewer and storm drain related operations. Approximately $7.6 million or 13 percent of the Commission’s 2010 direct expense budget was for the Engineering Division. About $4.4 million of the Engineering Division’s direct expense budget was for sewer and drain related work. Put another way, about $18.4 million was budgeted for Operations and Engineering Division’s direct expenses relating to sewer and drain work. Thus sewer and drain related work represents about 32 percent of the Commission’s total direct expense budget. The Current Expense Budget for 2011 had not been finalized as of the writing of this report. However, it is anticipated that the 2011 CEB will provide a similar level of funding for direct expenses relating to sewer and drain work. Stormwater related programs and activities funded under the Current Expense Budget include: • Illegal connection investigations and corrections • Illegal connection prevention • Illegal dumping and spill response • Infiltration and inflow identification and reduction • Issuing Drainage Discharge Permits • Storm drain inspections and sampling • Sewer and storm drain maintenance and general repair • Catch basin and particle separator cleaning and maintenance • Designing and installing new particle separators • Site plan review • New service inspections and dye tests • Issuing drain layers licenses • Designing and constructing capital improvements • Reviewing Environmental Notification Forms and Environmental Impact Reports • Public education • Rain data collection 6.2 CAPITAL EXPENDITURES The 2010-2012 CIP included $44.1 million for sewer and drain related projects, of which $14.1 million was earmarked for 2010. The Commission’s 2011-2013 CIP plan identifies $66.6 million for sewer and drain related projects, of which $20.5 million is earmarked for 2011. The complete 2011-2013 CIP plan is available on the Commission’s website at www.bwsc.org. 6 - 2
These costs do not include the cost of CSO separation projects that are funded by the MWRA under the MWRA’s CSO Control Plan. However, they do include the Commission’s costs for water and sewer work relating to the MWRA’s CSO Control Plan that is not eligible for MWRA funding. Programmatic activities covered under the 2011-2013 CIP include the following: • Preparation of a Wastewater/Drainage Facilities Plan. • Implementation of a system-wide sewer metering program. • Installation and upgrade of the Commission’s rain gauges. • Construction of a new storm drainage system along Morrissey Boulevard to facilitate sewer separation. • Relocation of the regulator on the Dorchester Brook Sewer to remove storm flow from 185 acres of land that currently flows to the New Boston Main Interceptor. • Identification and elimination of illegal connections to storm drains. • Renewal and replacement (R/R) of sewers and drains. • Projects to increase the capacity of existing sewers to maintain hydraulic capacity and structural integrity of the system, and prevent or reduce combined sewer overflows. • Separation of combined sewers in various areas of the city, with major projects occurring in the South End, Roxbury, Fenway/Kenmore, South Boston and Dudley Square. • Disconnection of downspout in Jamaica Plain, Dorchester, Allston-Brighton, West Roxbury, Roslindale, South Boston and Hyde Park. • Projects relating to the MWRA’s CSO control plan that are necessary, but are not eligible for funding by the MWRA. These include renewal and replacement of existing sewers and drains in the areas being separated, rehabilitation or relay of water mains in the areas, and associated paving costs. 6 - 3
