How It Works

Delivering sustainable solutions across the value‐chain

we turn environmental challenges into opportunities for growth and resilience.

At RSustain, we recognise that water is not just a resource—it is a strategic asset for business, environment and society. Proper management of both water supply and wastewater streams is central to achieving the “Planet” element of ESG and reducing operational and environmental risk, while unlocking value through reuse and circular economy.

Our Approach

Drawing on the proven model of PWSPL, RSustain offers short- and long-term, integrated solutions to water and wastewater challenges:

  • Conducting comprehensive water audits to understand consumption, losses, treatment inefficiencies and reuse potential (as PWSPL describes on its website).

  • Designing, commissioning and optimising water treatment plants (WTPs) and wastewater treatment plants (WWTPs) tailored to residential, municipal and industrial needs.

  • Operation & maintenance (O&M), including ongoing monitoring, performance optimisation, asset management and continuous improvement programmes.

  • Promoting reuse of treated water and wastewater, closing the loop in line with global best practice in water-resource recovery. For example, reuse strategies are essential for managing urban water stress.

Why it Matters?

Water scarcity & stress

Many regions face increasing pressure on fresh water supply. Strategic water management reduces supply risk and enhances resilience.

Waste-water burden & pollution risk

Untreated or poorly treated wastewater imposes heavy environmental, regulatory and reputational costs. Reviews show that many WWTPs in low- and middle-income countries under-perform due to weak design, O&M and institutional support.

Value creation through reuse

Treated wastewater can be repurposed for irrigation, industry, recharge and other uses—reducing fresh water demand and creating new revenue or savings streams.

ESG / compliance imperative

Effective water & wastewater management aligns with SDG 6 (Clean Water & Sanitation) and helps companies demonstrate genuine environmental stewardship and regulatory compliance.

RSustain’s Service Portfolio

Water Audit & Risk Assessment

Baseline water balance, losses and treatment efficiency
Benchmarking against sector-specific norms
Identification of efficiency, reuse and cost-reduction opportunities

Design & Retrofit of Treatment Systems

Modular and scalable WTP and WWTP solutions for varied sectors (industrial, municipal, residential)
Focused on process optimisation, low lifecycle cost, and robust operation
Emphasis on adaptability to reuse / circular water flows

Operation, Maintenance & Performance Optimization

Turnkey O&M services including monitoring, preventive/predictive maintenance, performance tracking
Institutional culture change and capacity building to avoid the common pitfalls of under-utilised plants. (As literature reports, many plants are built but not effectively operated).

Reuse & Circular Economy Integration

Evaluating treated water for reuse in irrigation, cooling, process water, groundwater recharge
Building business cases for reuse – cost savings, risk mitigation, brand value
Supporting clients in achieving zero liquid discharge (ZLD) or minimal discharge goals where relevant

ESG Advisory & Reporting

Linking water / wastewater performance to ESG metrics, using our proprietary framework (The ESG Compass – Navigating Strategy, Impact & Value)
KPIs on freshwater withdrawal, effluent quality, reuse rate, discharge volumes, regulatory compliance
Supporting disclosure in line with global frameworks (e.g., SASB, TCFD) and investor expectations

Why RSustain?

  • We bring end-to-end capability: from audit through design, commissioning, O&M and reuse strategy.

  • We apply our ESG-first mindset: every water solution is viewed through the lens of environmental impact, societal benefit and long-term value.

  • We understand that performance matters: many projects fail not due to design but due to weak O&M or institutional readiness. We build capability and ensure outcomes.

  • We provide context-specific solutions: centred on client sector, geography, regulatory regime and resource context (including high-stress zones such as GCC, India).

  • We align with your reporting and disclosure needs: integrating water & wastewater metrics into your ESG dashboard and management systems.
