In addition to the multiple consulting services that AEC can provide such as Studies or Capital Improvement Planning, our engineers have vast experience in obtaining grant funds and managing state and federally funded projects including EDA, Community Development Block Grants (CDBG), “C” Funds, HUD, Rural Infrastructure Authority (RIA), State Revolving Funds (SRF), and Water & Wastewater Infrastructure Funds (W&WIF). Our team is experienced with navigating the complex regulatory requirements in order to administer program-specific guidelines associated with these projects. The AEC team submitted 16 SCIIP applications on behalf of clients, procuring over $80M in grant funding for municipal infrastructure improvement projects. AEC is honored to work on the design and construction of these projects, playing a role to strengthen and modernize critical community infrastructure. Whatever the needs may be, AEC will provide the highest level of expertise in consulting services for our clients.

Lowcountry Regional Water System Water and Wastewater Rate Study

Cost recovery analysis studies including a comprehensive, independent cost recovery review of rates, fees and charges for the delivery of LRWS water and wastewater services, based on financial and customer consumption data. The rate analysis included a five (5) year projection based on growth, inflationary/indexed adjustments or other factors that may have a direct or indirect impact in the development of the projections. An additional analysis of various charges and fees including the water and wastewater rates, water and wastewater impact fees, fire service fees, water tap fees and wastewater tap fees was also be provided. The study included a comparative rate schedule for regional and statewide water and wastewater providers, and an examination of the existing rates, charges and fees, customer billing data, financial statements, bond requirements, capital improvement plans, cost recovery policies and other data that may be pertinent to a comprehensive analysis and development of the study.

West Columbia Rate and Capacity Fees Study & Financial Feasibility Report

Water and Sewer Rate Study, conducting a Capacity Fee Analysis, and preparing a Financial Feasibility Report. Recommendations were made, and subsequently adopted to implement a new rate structure for the City that better reflects the cost of service for each customer class, and provides for a more accurate distribution of water and sewer revenue.

Town of Edisto Beach Rate Study & Financial Feasibility Report

Water and sewer rate study and preparation of a Financial Feasibility Report. Historical revenue and expense trends were evaluated to determine future projections. In conjunction with the Rate Study, a Financial Feasibility Report was also developed.

Town of Blackville Sewer System Evaluation

AEC is providing an assessment of the existing wastewater treatment plant in order to evaluate plant performance and identify areas that are in need of upgrades, replacements, or operational adjustments in order to ensure future SCDHEC compliance. Additional services include an evaluation of the Jefferson Davis Academy (JDA) Subdivision Sewer System.

East Richland County Public Service District Sewer Basin Study

Engineering study to develop a wastewater service plan for an area consisting of approximately 500 acres. The scope of work involved an analysis of the proposed area to be served and included the development of future average and peak flowrates from the basin(s) as well as a generalized plan of service.

City of Cayce, S.C. Avenues Drainage Study

AEC conducted a storm drainage conveyance study including pipes and ditches due to persistent localized flooding in the Avenues portion of the City of Cayce. Data compiled was put into a hydraulic model in order to identify portions of the drainage system that were over capacity. The study evaluated a total area of 530 acres comprised of three separate drainage areas.

I-20 Wastewater System Evaluation Study

In connection with the Town of Lexington’s acquisition of the CWS I-20 Regional Wastewater System, a sewer system evaluation study and capital improvements plan was performed in order to identify the condition, capacity, location, and required future capital improvements for the system which includes approximately 101,000 LF of gravity sanitary sewer mains, 50,000 LF of force mains, 450 manholes, and 16 pump stations. The field data was collected by Town staff and then reviewed by AEC’s NASSCO Certified staff. In conjunction with gravity main inspection, a thorough inspection of all sixteen (16) pump stations was performed.

USC Smart Energy Campus Initiative Feasibility Study

Preparation of a feasibility study and development of a comprehensive plan for the transformation of the entire USC campus into a globally recognized “smart energy campus” that thrives on sustainability and energy responsibility – producing fewer greenhouse gas emissions and reducing waste while cutting its deferred maintenance debt and providing new research and learning opportunities for students all funded by the avoidance cost of current energy expenditures.

US Foods Wastewater Loading Evaluation and Wastewater Slug Discharge Management Plan

AEC assisted US Foods with monitoring of internal waste streams to assist with industrial pretreatment permit compliance at their Lexington, SC facility. AEC also prepared a Wastewater Slug Discharge Management Plan for US Foods’s Lexington, SC facility in accordance with EPA requirements.

Fairfield Joint Water & Sewer System Engineering Consulting Services for new WW System

AEC was retained to advise and assist the owner throughout the permitting process to design and construct a new wastewater system. As necessary, AEC principals meet with community leaders, community groups, governmental bodies, and regulatory entities to provide fact based educational materials on the scope of the project and the steps that are being undertaken by the owner to mitigate both the cost and environmental impacts of the project for all impacted parties.

Richland County Utilities Eastover WWTP 1.2 MGD Expansion process Review

Preparation of a technical memorandum. Services included engineering consulting necessary to perform an evaluation of Richland County’s Eastover Wastewater Treatment Plant to assess improvements required to the existing treatment equipment and unit processes in order to increase the average treatment capacity of the facility to 1.2 MGD.

City of Camden Water Distribution Improvements Study

Project consisted of a 10-Year Water Distribution System Capital Improvements Plan for the proposed replacement of waterlines within the City of Camden’s city limits and immediate surrounding areas. Emphasis will be made on asbestos-cement, cast iron, galvanized, and any needed enhancements to improve water age, system pressures and fire flow.
