As part of the redevelopment of a property located in the City of Richmond, the existing combined sewer segment running through the development was abandoned in place by the developer. This resulted in abandonment of the granite box sewer upstream on the developer’s property. The City of Richmond requested that a diversion of the upstream flow be created by installing a new 24-inch pipe using jack and bore along an alley, connection of the new alignment into an existing 12-inch pipe by installing a new manhole, and replacement of the existing 12-inch pipe with a new 24-inch pipe using open cut. The project also included installation of a temporary bypass pumping system to divert upstream flows until the construction was complete. 

ECE's tasks included--

In the Design Phase:     

• Preparing bid plans, specifications, and engineer’s estimate for the project

• Performing hydraulic evaluation for the new pipes and preparing a memo which included bases of design for the new pipes

• Conducting utility survey to include topographic, sub-utility, drainage and sanitary, and right-of-way survey

• Conducting geotechnical investigations along the proposed new pipe alignment

• Conducting dye-testing to verify lateral connections to the granite box sewer and upstream sewers

• Providing bid assistance to the city, which included attending pre-bid meeting with the city and procurement, and contractor’s bid review and evaluation

In the Construction Phase:

• Contractor’s submittal review for compliance with contract documents

• Attending construction progress meetings and perform part-time inspections

• Preparing record drawings

The City of Baltimore’s Sanitary Discharges of Unknown Origin Program is to identify, investigate and eliminate sanitary discharges in the city’s storm drain system. This program was started to comply with the EPA Consent Decree provisions.

A field crew tests storm drains at various locations within the city and identifies locations which test positive for the presence of ammonia (an indicator for sewage) in the water. Once a location is identified, ECE is tasked with investigating the area to identify the source and device solutions to eliminate the discharge.

During the investigation, ECE performs document research, coordinates CCTV and dye testing activities, performs CCTV video reviews, identifies sewer segments for lining, assists in drafting letters to the HCD (housing and community development) on behalf of the Wastewater engineering division is case of a plumbing code violation etc. 

 Environ-Civil Engineering, Ltd. (ECE) is sub-consulting for the Brewery Byproduct Processing Facility. The project involved designing a facility to accept, store and pump high strength brewery waste to various processes throughout the Wastewater Treatment Plant (WWTP).  A Preliminary Engineering Report (PER) was developed to identify potential alternatives and to estimate the cost and benefits of the project. 

The design included an unloading station with a bypass drain pipe.  A 0.75 million gallons (MG) sludge storage tank was repurposed to be partitioned with a new concrete wall to create a -0.15 MG storage facility. 

Mixers were sized and designed to be installed in the new storage tank to prevent settling. Progressive cavity pumps were sized and designed to pump the brewery byproduct waste to several final discharge locations:  fermenter tank, digestion tanks or gravity thickening tanks.  A 2,000 linear feet (LF) discharge pipe was designed to be routed through the existing tunnels to discharge to these locations.   

Richmond's wastewater treatment plant (WWTP) serves approximately 58,000 customers in the city and is the largest of its kind in Virginia.  Located along the south bank of the James River, the plant can treat up to 70 million gallons a day of sanitary sewage and stormwater before returning it to the river.  The wastewater utility also operates and maintains 1,500 miles of sanitary sewer, pumping stations, 38 miles of intersecting sewer lines, and the Shockoe Retention Basin, a 44-million gallon stormwater reservoir used during heavy rains.  The WWTP treats wastewater flows arriving from both the north and south sides of the James River, traveling beneath the river in some instances.  The Twin 66s are a pair of 66-inch diameter concrete interceptors, traveling from Chapel Island on the north bank of the James River to the south bank of the James River at the WWTP.  The Twin 66s have a large concrete Inlet Chamber, which collects flow before discharging into the Twin 66’s, and a large concrete Junction Chamber, which received flow from the Twin 66’s.  The City Lock Project is for the structural additions to the existing Inlet and Junction Chambers.   It also includes a new buried concrete gate structure and 72-inch sluice gate on the Lower Goodes Creek Interceptor along Brander Street.

The structural addition will provide access from grade to the Twin 66-inch siphons and the 96-inch Shockoe Interceptor for cleaning and maintenance. The project also includes design for a permanent all-weather access road from the Shockoe Retention Basin on Chapel Island to the location of the Inlet Structure near Richmond City Lock. The City of Richmond has requested that bid documents be compiled for the structure modifications and the new gate structure, including plans, specifications, and a project book for bidding general contractors. ECE was sub-contracted on as a sub-consultant whose tasks included design, drafting layout, sub consultant coordination, survey, geotechnical exploration and recommendations, field research, client meetings, and general project administration.

As a subcontractor, ECE conducted visual inspections and condition assessments of the City of Virginia Beach DPU’s 54 active water, sewer, and sewage force mains that cross over water bodies (aerial crossings). ECE completed digital forms presenting both the general characteristics of the crossings and the observed facility conditions along with recommendations. ECE’s project manager assisted with field efforts and co-authored the assessment report which documented the condition assessment criteria and results. This report included a summary of the field and desktop assessment methodologies, findings, remediation prioritization, recommendations, and feasibility level cost estimates for the recommended follow-up actions and capital improvements.

Field inspections involved visual inspections on foot where crossings are visible from land, and from boats where crossings are hung under roadway bridges spanning the waterways. Condition observations were recorded for piping, support structure, and general location-specific issues potentially affecting the crossing itself or access for remediation. Based on observations, field conditions, and/or record information, some crossings were identified for follow-up actions to further evaluate condition or criticality. Examples include non-destructive testing to assess wall thickness on older pipelines and desktop reviews of piping network to further assess risks by determining service bypass options if crossings were not available. Physical condition for each of the major components was rated based on a scale of 1 (excellent condition) to 5 (very poor condition). Desktop service-level criticality and risk assessments were also applied to address both service-specific and location-specific conditions for each crossing to develop a relative prioritization for crossing remediation. Criticality rating of 1 (low) to 3 (high) was assessed for each crossing based in part on proximity to critical users such as hospitals, schools, and resort/tourism areas. Other factors for criticality included pipe size and relative traffic ratings for the associated roadway. Relative risk was assessed by multiplying the physical condition rating by the criticality rating to provide a weighted risk value for each crossing and establish the prioritization. ECE’s efforts on this project were successfully completed within budget and schedule constraints. Added value was provided by applying forethought regarding endues of the final report documentation and preparing the final report as a living document for city operations personnel.

The District of Columbia Water and Sewer Authority (DC Water) recently identified necessary improvements to its sewer collection system.  They adopted the Sewer System Facilities Plan (Facilities Plan) produced by Engineering Program Management Consultant 3A (EPMC-3A) in June 2009.  Rehabilitation projects for the sewer system were identified as Capital Improvement Program (CIP) projects in the Facilities Plan.  The goal of the project is to address structural defects found through Closed Captioned TV (CCTV) inspections completed during the CIP development.  The preliminary construction cost estimation is $13.0 million, which is expected to change per future revisions to the project plan.

ECE's tasks included:

• Reviewed all available manhole inspection reports for manholes in the Northwest UPI Sewershed All inspection reports were reviewed for accuracy of NASSCO MACP coding to determine the appropriate rehabilitation method.

The Hampton Gardens area is located from Greenway Lane to Oak Lane between Grove Avenue and Harlan Circle. The scope of the project includes sewer rehabilitation work to an abandoned 1,080 linear feet (LF) existing and 1 existing manhole in easements through homeowners’ yards and in the street, along with a new gravity sewer main and manholes. The following is a summary of the tasks performed in the project:

Environ-Civil Engineering (ECE) reviewed closed-circuit TV (CCTV) inspection videos of sewer line segments provided by the City of Richmond to make a final determination of the repair needs. ECE engineers identified and investigated the potential cross connections using CCTV inspection and dye testing. The engineers reviewed CCTV inspection videos of storm sewer main lines that run adjacent to sanitary sewer line segments to document the condition of the storm sewer mains. ECE’s engineers performed site visits to identify utilities and potential utility conflicts; summarized the observations made during the field investigation in a letter report as a supplement to the Hampton Gardens Report. The engineers prepared work assignments for rehabilitation work using the annual services cured-in-place pipe (CIPP) and open excavation contracts to correct the potential sources of cross connections being investigated. ECE’s engineers provided work assignment drawings and cost estimate for the open trench pipe replacement of line segments. The engineers designed the replacement of the existing sanitary sewer line with a new pipe to improve the pipeline’s alignment as recommended by the report. A field survey was performed to delineate property lines, identify potential utility conflicts and identify topographic features along the proposed sewer routes. ECE engineers observed the installation of approximately 1,100 LF of8-inch diameter sewer in a new alignment in Roslyn Road and Harlan Circle. The engineers also observed the installation of a total of 8 new manholes, 6 manholes along the new alignment. ECE engineers observed site and street restoration to include landscaping and traffic control; prepared field survey maps to show existing sanitary, storm, other utilities, and easements to property lines from the City’s GIS files and contours along the proposed sewer routes. ECE also prepared the cost estimates for project and provided construction phase services.

This project consists of sewer rehabilitation projects in sewershed areas 5-7 and 7-5 in the City of Richmond, Virginia. Sewershed area 5-7 is bounded by Shadwell Road, Westmoreland Street, Cary Street and Hanover Avenue. Closed Circuit TV (CCTV) videos of approximately 16,200 LF of sanitary sewers and manholes were reviewed in this sewershed. Sewershed area 7-5 is bounded by Henrico Turnpike, Meadow Bridge Road, Gladstone Avenue and Brookland Park Boulevard. Closed Circuit TV (CCTV) videos of approximately 22,450 LF of sanitary sewers and manholes were reviewed in this sewershed. Excel spreadsheets with sewer line defect coding were prepared. Field inspections were performed to identify feasible alternatives for rehabilitation of sanitary sewers in these sewersheds. Suitable rehabilitation alternatives were recommended to the City along with cost estimates and detail plans for rehabilitation. ASTM F1216-07b standards were used to determine the Cured-In-Place Pipe (CIPP) lining thickness.

The City of Richmond wants to develop a Stormwater Master Plan for the entire city to identify and prioritize recommended capital improvement projects for mitigating flooding, strengthen or improve the stormwater infrastructure, prevent stream bank erosion and improve stream water quality. The City has identified and prioritized watersheds within the City and Riverfront Watershed is one of them.

The project is currently on-going. ECE’s responsibilities include:

• Delineating the watershed and subbasins using GIS
• Fieldwork after a storm event to observe the various types of stormwater infrastructure (inlets, culverts, ditches, etc.) within the watershed and identify potential improvements or problem areas. 
• Typing up reports in a template as well as putting data into a PowerPoint presentation template to present to the City of Richmond for further evaluation. 

Potential projects have been identified and will be presented to the City for its review. The City will then provide comments and the reports will be revised accordingly before action is taken. 

The City of Richmond’s Water Treatment Plant (WTP) utilizes finished, potable water for many uses within the WTP itself.  The existing plant water system continues to have numerous potential cross-connections.  Plant water schematics identified many areas where potable (e.g. restrooms, emergency showers and eye washes) and non-potable (e.g. chemical dilution) uses are interconnected in the same piping system for both Plants 1 and 2.  This project separated the potable and non-potable uses into two separate water supply systems. The work involved the design of upgrades to the PWS to separate potable uses from non-potable, eliminating cross-connections, and the work also involved the design of installation of water meters and backflow devices on PWS feeds to Plant buildings. The tasks included evaluation of the size/capacity of PWS needs, developed preliminary plan to separate the potable and non-potable PWS, preparation of sizing calculations, review of capacity and condition of existing piping to remain in service where appropriate and sizing new PWS piping. ECE designed the repair and removal of the 6-inch main to Loch Lomand Lane. Contract documents were provided in bid packages to allow the city to issue construction documents to Annual Services Contractors to complete the work in phases. Services during construction include inspection, answering contractor questions, and providing record drawings. ECE prepared record drawings based on mark-ups from each Annual Contractor.

Environ-Civil Engineering, Ltd. (ECE) was asked to provide engineering services for the City of Richmond during the project called Screenings and Grit Facility Preliminary Engineering Report (PER).

ECE provided an Engineer, he assisted in composing a PER for the new Screenings and Grit Removal Facility at the Richmond Wastewater Treatment Plant (WWTP). 

The project involves design of an improved screening and grit removal facility capable of handling 140 million gallons per day (MGD) during wet weather events. The PER presented several alternatives, required modifications to the existing WWTP and cost estimates for the upgrade. 

Construction documents were developed for the new facility were designed along with a new odor control system to serve the facility. Modifications were required to connect the existing 96-inch force main from the Main Piping Station with the new facility. A new diversion chamber was designed to divert the flow from the 96-inch force main to the new facility. The existing diversion chamber was modified to serve as an emergency bypass overflow structure with fixed weirs. A 72-inch pipe was designed to convey the emergency bypass flow and to tie into the system just downstream of the new facility. Multi-rake screens were designed in isolated channels to remove screenings and to discharge to trucks on the ground floor. Vortex grit removal units were sized and designed to remove grit which would be pumped to the top floor, classified and removed. An odor control facility was designed to treat the odorous air from the new facility. The design included biological towers, odor control fans and duct work.

 Harford County Department of Public Works obtained Construction Management services to oversee the construction on various capital improvement projects. Environ-Civil Engineering (ECE) was part of the construction management team on the Sod Run WWTP ENR Upgrade project. ECE provided inspection and monitoring services of the general contractor’s daily work activities as well as third party inspectors, for concrete, rebar, and soils inspections for expansion and rehabilitation of plant process reactors and clarifiers.

ECE’s inspector prepared and maintained a daily construction inspection report/log documentation of field activities which included: the status of existing tasks, commencement of new tasks, inventory of major equipment on the site, tests performed, problems and errors in the field, items not conforming to project documents etc.

ECE’s inspector documented and verified site work on a daily basis such as materials, location, dimensions, quality etc. to ensure conformance with the project documents. Additionally, the inspector scheduled and coordinated all quality assurance testing on the site including third party testing. Using Primavera CM-13 software, the inspector reviewed and checked RFI’s and submittals.

ECE’s inspector scheduled third party inspectors for soils inspections and concrete testing. ECE’s Inspector compiled daily report work activity. 

Richmond's wastewater treatment plant (WWTP) serves approximately 58,000 customers in the city and is the largest of its kind in the state of Virginia.  The treatment plant is located along the south bank of the James River. The plant can treat up to 70 million gallons a day of sanitary sewage and stormwater before returning it to the river.  The wastewater treatment plant also operates and maintains 1,500 miles of sanitary sewer, pumping stations, 38 miles of intersecting sewer lines, and the Shockoe Retention Basin, a 44-million gallon stormwater reservoir which is used during heavy rains.

The Whitcomb Court Sewer Improvement project is a residential gravity sewer replacement project within the City of Richmond. The project includes the abandonment of 1230 linear feet of the existing 12-inch diameter sewer. The removal of the Shockoe Creek Crossing (a portion of aerial sewer which crosses the Shockoe Creek), and the installation of approximately 1775 linear feet of a 12 inch-diameter ductile iron sewer in a new alignment in Sussex Street, from Hospital Street to Carmine Street. The project also includes new manholes and associated tie-ins to existing sewers. The replacement sewer will intercept the existing sewer behind the Richmond redevelopment and housing authority (RRHA) Building on Carmine Street and will run generally south in the existing roadway. The City of Richmond has requested that bid documents be compiled for the new sewer, including plans, specifications, and a project book for bidding by general contractors. The project tasks include design, drafting layout, sub consultant coordination, survey, geotechnical exploration and recommendations, field research, client meetings, and general project administration. Environ-Civil Engineering (ECE) is involved in all aspects of the project and will be providing construction administration services after Award. Currently, ECE is at the 90% design stage and proceeding with final design efforts.  The RFQ process by the City Procurement department has been started and is anticipated to be complete by March of 2013.  Final Design is anticipated to be completed by April of 2013.  Award of Contract and Construction is anticipated for fall of 2013.

Washington Sanitary suburban Commission (WSSC) complied with a consent decree (CD) that required that a system-wide fully-dynamic sanitary sewer system model be developed. The sewer system models developed under this contract will be applied in subsequent studies to prepare sewer system repair, replacement, and rehabilitation plans.

ECE was subcontracted to develop Dynamic Hydraulic Sewer Models for WSSC using InfoWorks CS software. WSSC provides public water supply and sanitary sewer service to approximately one million residents in Montgomery and Prince George’s Counties comprising the northern, western, and southern suburbs of Washington, DC. The primary objective of the study is to use the model to determine the existing and long-term capacity of the Commission’s wastewater collection system. Rainfall, population projections, manholes, pipes and wastewater pumping station data were analyzed in GIS and the collection system network was modeled using InfoWorks CS software. The model was run to evaluate the future dry weather flow and wet weather flow (for standardized storms). The results of the study were documented in a report submitted to WSSC. ECE performed the following steps to develop the model: Initial Data Assessment, GIS Sewer System Data Processing, and import of Data into the Model. This stage also identified and documented the critical data such as pump station information, flow diversions and standard operating procedures required to perform the modeling. The data imported was verified and validated to identify and remove duplicates, and to identify pipes and manholes with missing data to check the network against available record drawings to correct and/or fill in the missing data. Area estimates were prepared from aerial photographs using GIS tools like Arc MAP. Verification, Validation and Calibration of the Network, Dry Weather Flow Analysis, Simulations of Design Storms, Wet Weather Flow Analysis, and Capacity Analysis as well as a Final Basin Modeling Report was prepared.

Under this BOA, there have been currently 18 task orders that covered areas such as WSSC sewer basin facility plans, capacity reevaluations of wastewater pumping stations and model networks, recalibrations of model networks, modeling support, and analysis for new developments. Four of the eighteen tasks are on-going. Tasks were performed within budget and on-time.
