PERC Water has designed over 60 water/wastewater facilities. Our unique ability to take a client’s project from design to construction and through to operation, allows us to adjust and provide the best proven solutions for our clients. Through each phase of a project, we incorporate our operators’ knowledge and expertise in choosing the right equipment and design layout for each individual facility. This allows maximum efficiency and cost savings.

Through extensive research and experience, we have formulated our own trademarked Activated Sludge Process design (ASP™) which provides efficient, environmentally sensitive solutions for wastewater treatment. The PERC ASP™ design guarantees:

  • Highest water quality guaranteed to meet or exceed permits
  • Fixed capital cost, operating cost and a delivery schedule
  • A small environmental footprint where all treatment takes place underground
  • Covered process tanks allow for maximum odor control and noise reduction
  • Cost-sensitive design features like common wall construction and less yard piping/conduits
  • Scalability

Operations and Maintenance

PERC Water is a water quality and risk management firm providing clients with a Total Solution™ for water recycling needs. Our team members have more than 30 years of experience providing innovative and proven engineering, construction, and operations on projects throughout the United States and abroad. A key element of PERC’s Total Solution™ is Operation and Maintenance (O&M). PERC Water recognizes water reclamation facilities as highly specialized and complex production facilities, and as a result, has developed practices such as our proprietary Operation and Maintenance Staffing Recruit, Operate, Train, and Transition Employees (ROTATE™) program which assists our clients with staffing. Overall, our O&M guarantees:

  • Cost
  • Energy efficiency
  • Extended equipment warranties
  • Regulatory compliance


Concessions and Asset Management

PERC Water recognizes that water recycling facilities are highly-specialized, state-of-the-art production facilities and assets to their city and community. We have found that municipalities can leverage operational efficiencies, like alternative energy solutions, within this existing infrastructure in exchange for an up-front cash payment to the city.

Essentially, cities can extract value they didn’t know they had out of an asset they already own.

The purpose of PERC Water’s Asset Management Team is to minimize the client’s total cost to own and operate the facility, increase the overall efficiency of the facility and to deliver the highest level of service to every client. Our approach is focused on achieving four goals:

  • Long-term reliable service
  • Outstanding process performance
  • Budget-responsible and efficient operation
  • An extended life-cycle

Our Asset Management and Operations and Maintenance (O&M) division also features a program designed to assist water infrastructure owners in restructuring their operations to bring a facility into compliance. As part of this program, we provide our clients with PERC Water’s proprietary Turn Around Plan (TAP™). PERC Water’s TAP™ services include a comprehensive evaluation of the existing facility, a solution to bring the facility back into compliance within current applicable regulatory requirements, an assessment of the facility’s energy consumption and a full evaluation of alternate operational approaches to maintain such compliance over the long term. PERC Water has a proven track record in bringing non-compliant facilities into compliance with current applicable regulatory requirements.

Public-Private Partnership

PERC Water is considered an industry expert in the utilization of public-private partnerships, and in particular, we developed the first 100% privately funded water recycling facility in the US. We have developed strategic partnerships with prominent infrastructure investment firms who are seeking mission critical infrastructure investments with a low risk profile, such as water and wastewater related assets. In the current market, private financing sources are readily available to be deployed, typically without the timing constraints that are required for State Revolving Fund and/or municipal bond financing arrangements, and can accelerate the timing of a new project launch and completion.

The key advantage of utilizing project financing is that these investors focus on lifecycle perspective, whereby they invest up front in design and construction costs necessary to deliver the appropriate level of service over the life of the project and remove the uncertainty of project financing and future capital expenditures from clients.
