Evolving regulatory requirements and aging infrastructure present challenges to existing wastewater facilities. With diverse expertise, we can help plan and design solutions to overcome the challenges facing your wastewater system. Designs range from single cell lagoon systems to complex plants, lift stations, flow equalization basins, force mains, and gravity mains. From evaluating your current system through facility plan preparation, the creation of design documents, bidding, construction services, and funding opportunities, we’re prepared to assist with all project aspects.
We’re client-focused—not project focused, so once improvements to your wastewater system are complete, we’ll remain involved to guide operation and maintenance. Wastewater system improvements to achieve regulatory compliance can be radically different and unfamiliar to your operations team. With licensed, on-staff operators, we’re uniquely prepared to address your needs by temporarily assisting with the start-up of new technology as your staff becomes familiar with it. We’re also available to help develop operational procedures and documents to guide smooth, efficient operation long-term.
System Analysis & Planning
With expert staff on-hand, we provide sewer system modeling, condition assessments, inflow and infiltration analysis, and treatment facility performance analysis. These resources are integral to develop cost-effective capital improvement plans and assist with budgetary forecasting to maintain wastewater infrastructure.
A wealth of knowledge and experience regarding various funding sources and their unique requirements has prepared us to guide you through the steps necessary to acquire critical project funding. Traditional funding sources include the Community Development Block Grant (CDBG), State Revolving Fund (SRF), and United States Department of Agriculture (USDA RD) Loans.
The permitting process for water projects can be complicated, particularly when receiving funding assistance. For this reason, it’s critical to work with a firm that’s familiar with funding requirements. Our team of wastewater professionals has an extensive background in all areas of permitting and works directly with regulatory staff. Each project is unique with numerous conditions to meet before construction permits become available. We coordinate with regulatory agencies daily, especially in the early stages of a project, to keep everything on schedule.
Construction Plans & Specifications
We have a proven track record of consistently producing high-quality construction plans and specifications that contractors are comfortable with, which is reflected in the bid price. Clear and concise bidding documents are essential to accurately estimate construction costs and obtain competitive bids.
Gravity Sewer Design & Operation
Gravity sewers were one of the earliest methods of wastewater management. Over time, numerous improvements to piping systems have changed how wastewater is transported from houses, businesses, and industrial facilities. Our experience with new gravity sewer systems ranges from simple development sewer extensions to large diameter trunk sewers through congested urban areas. Regardless of project size, we have the resources needed to provide sustainable solutions.
Pump Station & Force Main Design
While gravity sewers typically convey wastewater, on occasion, elevation restrictions or topographic features require the use of pressurized sewers to convey wastewater downstream. Our team has designed systems ranging from small, individual pump stations to large, multi-pump facilities capable of pumping millions of gallons per day. By evaluating multiple options, the optimum solution is implemented for the unique circumstances of each project. We also have experience designing complex control systems including supervisory control and data acquisition (SCADA), variable frequency drive (VFD), and eddy current drive speed control systems.
On-Site Treatment System Design
Remote areas without access to public sewer infrastructure often utilize on-site treatment methods to manage wastewater such as septic tanks, sand filters, lateral fields, aerobic treatment units, and land application. Every location presents unique challenges, so we approach with an open mind and communicate regularly with clients to implement the best solution for their system needs. Our team is well-versed in regulatory requirements and has successfully designed numerous on-site wastewater treatment systems.
Treatment Facility Design
From simple lagoon systems to fixed film mechanical plants and complex activated sludge treatment facilities, we’re prepared to help. Additionally, we can assist with disinfection systems such as chlorination/de-chlorination or UV. Staff engineers on our team, that are licensed wastewater operators, can guide startup and stabilization of your new system.
