The following Engineering CIP projects are described on this page because they are more geographically distributed or otherwise not well-suited to mapping.
Purpose: Purchase and install new air release valves on the 24" water main that conveys finished water from the Water Treatment Plant to the City's distribution system. The air release valves are reaching the end of their serviceable life and are in need of replacement.
Status: This is a new project for the FY 2008 CIP.
Staff Contact: Department of Public Works, Craig Daly, Civil Engineer II, 240-314-8500.
Purpose: This project represents the City's share of costs to upgrade and enhance the wastewater treatment and solids handling facilities at the Blue Plains Waste Water Treatment Plant (BPWWTP), which is owned and operated by the District of Columbia Water and Sewer Authority (DC WASA). All of Rockville's wastewater is conveyed through Washington Suburban Sanitary Commission (WSSC) system for treatment at the BPWWTP, which has a total treatment capacity of 370 million gallons per day (mgd). WSSC’s allocated capacity is 169.6 mgd, of which Rockville is allocated 9.31 mgd. WSSC has four projects, which support many individual DC WASA CIP projects. As new projects are approved by DC WASA, costs will are to this project. The amounts listed represent Rockville’s share (at 5.5 percent) of WSSC total costs. The WSSC share is approximately 46 percent of the Blue Plains costs in accordance with the 1985 Inter-Municipal Agreement. This project provides required sewage treatment capacity to serve the City's expansion needs through build-out. There are two main project categories: implement environmental regulations, and systems maintenance and reinforcement.
Status: Implementation. This project first appeared in the FY 2003 CIP.
Staff Contact: Department of Public Works. Susan Straus, Chief Engineer/Environment, 240-314-8500
Purpose: This project funds the update of the Cabin John Creek Watershed Study. First adopted in 1996, the study has supported several stormwater management (SWM) and stream improvement projects that have been constructed. This update provides information on the condition of the Cabin John Creek, the effectiveness of SWM implemented through the original study, the identification and assessment of further SWM or watershed improvements, or other Best Management Practices (BMPs).
First Appeared in Rockville's Capital Improvement Program: Fiscal Year 2004.
Staff Contact: Department of Public Works, Craig Daly, Civil Engineer II, 240-314-8500.
Purpose: This project funds system improvements, recommended through the Sewer System Evaluation Survey (SSES) and an Infiltration and Inflow (I/I) Analysis in the Cabin John Basin. The survey and analysis systematically identify the condition of the sewer system and provide comprehensive rehabilitation methods. System rehabilitation reduces I/I, which decreases the flow in the Rockville and Washington Suburban Sanitary Commission (WSSC) sewers, and ultimately the flow to the Blue Plains Wastewater Treatment Plant.
Status: Concept. This project first appeared in the FY 2004 CIP. In Spring 2005, emergency repairs were conducted at Dogwood Park.
Staff Contact: Department of Public Works, Jim Woods, Civil Engineer II, 240-314-8500.
Purpose: This project funds a Sanitary Sewer Evaluation Survey (SSES) and an Infiltration and Inflow (I/I) analysis in the Cabin John Basin, which systematically identifies the condition of the sewer system and develops comprehensive rehabilitation methods. Fieldwork includes smoke testing, manhole inspections, light cleaning, close-captioned television and dye testing. Rockville will participate in a larger SSES and I/I Analysis conducted by WSSC. System rehabilitation reduces I/I, which decreases the flow in the Rockville and WSSC sewers and ultimately the flow to the Blue Plains Wastewater Treatment Plant. Under the terms of the 1956 agreement between Rockville and WSSC, Rockville’s peak wastewater flow is limited to 6.8 million gallons per day (MGD) in the Cabin John Basin. Ultimate development, as projected in the City’s Master Plan, will exceed the 6.8 MGD limit. However, a 15-20 percent reduction in I/I may maintain flows below the 6.8 MGD limit.
Status: Implementation. This project first appeared in the CIP in FY 2003. The field work is completed and the analysis and report are underway.
Staff Contact: Department of Public Works, Craig Daly, Civil Engineer II, 240-314-8500.
Purpose: This project funds the development and analysis of a comprehensive hydraulic sanitary sewer model for the City's Cabin John sewer basin. Such analysis is necessary to determine the adequacy of the capacity of the sanitary sewer system created by aging pipe and new development occurring throughout the City. This project identifies inadequacies in the capacity of the system, determines the allowable future capacity in the existing system, and determines areas of required upgrades to support future development. The project also creates a schedule to implement required future improvements in conjunction with the results of the Sanitary Sewer Evaluation Study (SSES) and Infiltration and Inflow (I/I) analysis completed in the Cabin John sewer basin.
Status: Concept. This is a new project for the FY 2008 CIP.

Staff Contact: Department of Public Works. Jim Woods, Civil Engineer II, 240-314-8500.
Purpose: This project funds the design and rehabilitation of corrugated metal pipe (CMP) storm drain systems installed in many locations, as well as studies to asses the condition of storm drain systems. CMP was used in the late 1960’s as a means to install new drainage systems economically. Most of the systems have exceeded their design life, and need to repeated maintenance, generally due to rust. Phase I study recommends, limited to pipes 48” in diameter and greater, include concrete lining of the inverts in all cases along with other minor repairs. Smaller diameter pipes will be studied in phase II.
Status: Planning. This project first appeared in the FY 1998 CIP.
Staff Contact: Department of Public Works. Jim Woods, Civil Engineer II, 240-314-8500.
Purpose: This project funds the design of stream restoration. This project allows staff to initiate design on unplanned and previously unidentified stream erosion issues in a timely manner. Staff will work closely with the community in the concept refinement phase to evaluate project goals and construction access to minimize the impacts on the forest, and active and passive recreational areas. The focus will be to select a design and location that will arrest the active stream erosion, while minimizing the impact on the community's access to usable open space and minimizing tree loss. Because no projects are identified, no construction is included.
First Appeared in Rockville's Capital Improvement Program: Fiscal Year 2005.
Staff Contact: Department of Public Works, Lise Soukup, Civil Engineer II, 240-314-8500.
Purpose: This project funds the hydraulic analysis, leakage survey, and fire flow analysis for the City's public water distribution system, as well as updating the City's water modeling software, WaterCAD.

First Appeared in Rockville's Capital Improvement Program: Fiscal Year 2004.
Staff Contact: Department of Public Works, Craig Daly, Civil Engineer II, 240-314-8500.
Purpose: This project funds the construction of a separate water booster station along Glen Mill Road south of Boswell Lane to increase the flow of water into Rockville in support of the City's Master Plan level of projected development. The current plant capacity is inadequate to meet current water requirements during peak summer use. Therefore, the City must purchase water from the WSSC to meet peak demand. A water conservation program will be implemented with a combined approach of increasing water production and decreasing demand. In addition, this project provides for a Supervisory Control And Data Acquisition (SCADA) system that integrates monitoring remote water system facilities (Glen Mill Road pump and storage tanks) and remote wastewater pump stations (Horners Lane and Fallsgrove).
First Appeared in Rockville's Capital Improvement Program: Fiscal Year 1999.
Staff Contact: Department of Public Works, Mike Wilhelm, Chief of Contract Management, 240-314-8500.
Purpose: This project funds two phases of analysis of the critical systems at the water plant for both regulatory and capacity requirements. The results from the phase I analysis indicate that improvements to the residential handling systems are needed to meet Maryland Department of the Environment recycle backwash regulations. Other changes to the clarifiers, filters and chemical feeder systems will be needed to meet new Environmental Protection Agency Disinfection Byproducts Rule and Long Term 2 Enhanced Surface Water Treatment Rule. Due to the proposed cost of these improvements a detailed alternatives analysis will be prepared as part of the phase II analysis. Other improvements, such as enlarging pipes coming out from the clarifier, improvements to the electrical system and miscellaneous associated work will also be analyzed as part of the phase II analysis and are included in this project.
