Why Decentralize Sanitation?

Wastewater is generated everywhere — but centralized sanitation infrastructure is not always practical or economical for every location.

Aventiq is developing decentralized treatment systems that bring treatment closer to where wastewater is generated, enabling local water recovery and responsible solids management.

INFRASTRUCTURE

Centralized sewerage can require extensive networks, pumping infrastructure and long-distance conveyance.

WATER

Treated wastewater can become a local resource when appropriately treated for defined non-potable applications.

SOLIDS

Effective sanitation requires responsible management of the solids generated during treatment — not simply treatment of the liquid stream.

Treat closer to the source. Recover water locally. Manage solids responsibly.

Two streams. One closed loop.

CIRCULAR WATER
Source homes · communities
Treat modular system
Recover water + solids
Reuse non-potable

Liquid and solids, both recovered

  • Liquid: treatment → polishing → defined non-potable reuse
  • Solids: separation → controlled drying / thermal processing → resource recovery
  • No dependence on biological microbes as the core mechanism, and membrane-free
  • Designed to reduce intensive power and routine consumables

Three Platforms. One Decentralized Sanitation Vision.

Aventiq is developing a modular portfolio of sanitation technologies for different scales and deployment environments.

HySan-HTS household-scale decentralized wastewater treatment system
Household-Scale Sanitation

HySan-HTS

Compact decentralized wastewater treatment designed for homes and small residential applications.

HySan-HTS is being developed for approximately 3–4 bathrooms, combining wastewater treatment, water polishing and a controlled solids-management pathway within a compact system.

  • Designed for: Homes and small residential settings
  • Focus: Local wastewater treatment • Water recovery • Solids management
HySan Circular community-scale decentralized sanitation and water recovery system
Community & Institutional Sanitation

HySan Circular

A modular decentralized sanitation platform designed for housing communities, institutions, campuses and distributed facilities.

HySan Circular extends the decentralized treatment approach to higher-flow applications, with integrated water recovery and consolidated solids management designed around the needs of community-scale operation.

  • Designed for: Housing communities • Schools & campuses • Healthcare & institutional facilities • Rural clusters
  • Focus: Community-scale wastewater treatment • Water recovery • Consolidated solids management • Resource recovery
SAPP solar-powered mobile toilet and resource recovery system
Advanced Off-Grid Sanitation & Resource Recovery

SAPP

Solar-Assisted Pyrolysis & Electrochemical Polishing for off-grid and resource-constrained environments.

SAPP brings together decentralized water treatment and advanced solids resource recovery for locations where conventional sewerage, centralized treatment or reliable grid infrastructure may be difficult to provide.

  • Designed for: Remote communities • Rural locations • Off-grid and resource-constrained environments
  • Focus: Water recovery • Solar-assisted operation • Advanced solids resource recovery

Shared technologies. Different system architectures.

HySan platforms are designed around configurable, modular wastewater treatment and solids management. SAPP is being developed around the integrated use of solar-assisted pyrolysis and electrochemical polishing. Thermal processing, including pyrolysis, may also be evaluated within HySan Circular where feedstock, operating conditions and system economics justify it.

OUR APPROACH

Engineered Integration. Adaptive Treatment. Real-World Resilience.

Aventiq develops modular sanitation architectures by engineering the integration of multiple treatment processes into coordinated systems. Our approach focuses on process configuration, system-level optimization and adaptation to changing wastewater characteristics and shock loads. Through iterative engineering, controlled testing and real-world validation, we aim to deliver robust, maintainable systems designed for consistent performance across varying operating conditions.

Answers to Common Questions

Frequently Asked Questions

Understand Aventiq's decentralized technology portfolio, processes, and deployment models.

Decentralized sanitation treats and manages wastewater closer to where it is generated rather than relying entirely on centralized sewerage and treatment infrastructure.
