Wastewater Process & Planning

SOLUTIONS FOR:

Do more. Do it better.

Our nation’s water bodies are cleaner today than they have been in decades, yet water quality challenges still abound. Utilities are striving to increase capacity and improve the efficiency of existing facilities, while meeting ever-more-stringent regulations, conserving energy, and minimizing adverse environmental impacts and maintaining customer’s rates.

Communities subject to combined sewer and sanitary sewer overflow (CSO/SSO) regulations are looking to maximize the capacity of wastewater treatment plants during wet-weather events. Other wastewater constituents, such as nutrients like nitrogen and phosphorus, are also facing increased scrutiny because of their effect on water quality.

Our Approach

Malcolm Pirnie takes a hands-on approach to system and facility planning, design, and construction. We work with your staff to clearly understand all of the issues you face and your specific needs, and to develop solutions that maximize your flexibility to meet uncertainties. We use scenario planning — asking “what if …” — to identify the critical factors and limitations to solving your immediate problem as well as potential future challenges.

We harness the power of innovative, advanced treatment technologies, such as high-purity oxygen activated sludge, selector technology, biologically aerated filters, high-rate sedimentation, pulsed ultraviolet disinfection, integrated fixed-film activated sludge, enhanced nutrient removal, and membrane biological treatment. We pay special attention to operability and maintainability in selecting the most appropriate technology based on your wastewater’s physical, chemical, and biological characteristics and your site’s unique conditions and constraints.

The result is a facility that uses state-of-the-art, proven wastewater treatment technology that can be operated and maintained to meet today’s standards, and that has the flexibility to meet future needs.
