Your challenges
Municipalities today face rising demands to manage wastewater efficiently and sustainably while balancing tight budgets and aging infrastructure.

Outdated or Overloaded Wastewater Infrastructure
Many municipal systems struggle with population growth, climate change, and extreme weather events, leading to frequent breakdowns, sewage overflows, and service disruptions.
High Maintenance Costs and Limited Monitoring
Without smart monitoring and automation, municipalities often rely on reactive maintenance, resulting in higher operational costs, unplanned downtime, and inefficient use of resources.
Strict Environmental Regulations
Compliance with increasingly stringent water quality standards—including the removal of micropollutants, nitrogen, and PFAS—requires advanced treatment technologies that many traditional plants lack.
Community Concerns Over Public Health and Water Quality
Residents expect safe, clean water and reliable wastewater services. Municipal systems must consistently meet these expectations by eliminating harmful contaminants and protecting local ecosystems.

-
Optimizing Operations and Reducing Costs – Deploying monitoring tools and automation to cut maintenance expenses and improve system performance.
-
Recovering Resources for Sustainability – Turning wastewater into a resource through water reuse and energy-efficient treatment solutions.
With decades of expertise and a commitment to innovation, Saur enables municipalities to protect their communities, meet environmental obligations, and secure a sustainable future.

Types of Wastewater
-
Municipal Wastewater – from homes, schools, and businesses
-
Industrial Wastewater – from manufacturing and chemical processes
-
Agricultural Wastewater – runoff from farms containing fertilizers and pesticides
-
Stormwater – rainwater carrying debris and pollutants from urban surfaces
Benefits of Wastewater Treatment
Effective municipal wastewater treatment:
-
Protects public health by removing harmful pathogens and pollutants
-
Preserves clean water resources and supports safe water reuse
-
Reduces pollution and minimizes environmental impact
-
Supports circular water economies by recovering energy and nutrients
Effects of Wastewater Pollutants
Untreated wastewater carries substances that can severely harm communities and ecosystems:
-
Pathogens (bacteria, viruses) – cause diseases
-
Chemical Pollutants (PFAS, heavy metals, pesticides) – contaminate water sources
-
Nutrients (nitrogen, phosphorus) – trigger algal blooms and oxygen depletion
-
Micropollutants (pharmaceuticals, plastics) – disrupt aquatic life
Stages of Wastewater Treatment
Primary Treatment
Screens and sedimentation tanks remove large solids and debris.
Aeration/Activated Sludge Process
Microorganisms break down organic pollutants in oxygen-rich conditions.
Secondary Treatment
Biological treatment eliminates dissolved and suspended organic matter.
Tertiary Treatment
Advanced filtration, chemical, or membrane processes remove remaining contaminants, including micropollutants and pathogens.

FAQs
Which wastewater treatment is most effective?
Activated sludge combined with tertiary treatment achieves the highest pollutant removal rates.
What are the latest technologies in wastewater treatment?
Membrane bioreactors (MBRs) and advanced oxidation processes represent the most innovative solutions.
Can wastewater treatment plants produce drinking water?
Yes. With advanced processes, treated wastewater can be reclaimed to potable standards, particularly valuable in water-scarce regions.
