Revenue model

1. Engineering, Procurement, and Construction (EPC) of Wastewater Treatment Plants: Design, procurement, installation, and commissioning of turnkey wastewater treatment installations for municipal and industrial clients. Projects range from pretreatment equipment to complete plant construction (e.g., Yverdon-les-Bains biology renovation project worth CHF 5,383,000). Revenue is project-based with multi-year delivery timelines.
2. Aftermarket Services, Spare Parts, and Maintenance Contracts: Own customer service provides complete plant support including spare parts replacement, equipment renewal, welding and assembly, service contracts ranging from ad-hoc interventions to ongoing operational support, water quality monitoring, and plant audits. Dedicated service team with regional coverage (French-speaking, German-speaking, and Italian-speaking Switzerland).
3. Membrane Stripping — Fertilizer Production from Recovered Ammonia: Technology developed jointly with Membratec SA recovers ammonium from wastewater to produce a high-quality fertilizer sold directly to Swiss farmers via the CULTAN method. Currently operating at two installations (Yverdon-les-Bains and Altenrhein), producing daily recycled fertilizer. This closes a local circular nutrient economy loop.

Core offering

ALPHA WasserTechnik AG is a Swiss engineering company that designs, procures, installs, and commissions turnkey wastewater treatment plants and industrial water treatment systems. Its portfolio covers the full treatment chain — mechanical pretreatment, physico-chemical, biological (activated sludge, biofiltration, MBBR, SBR, Anammox, oxidation ditch), tertiary, micropollutant elimination, sludge treatment, and odor treatment — for municipal authorities, inter-municipal wastewater associations, and industrial clients, complemented by a complete aftersales service offering (spare parts, welding, maintenance contracts, audits).

Product overview

ALPHA WasserTechnik AG is a Swiss water treatment engineering company offering a comprehensive, modular portfolio of turnkey wastewater treatment solutions and industrial water systems. The core offering is organized around the full wastewater treatment chain: Mechanical Treatment (Nordic Water/MEVA screens, presses, sand washers), Physico-Chemical Treatment, Biological Treatment (activated sludge, biofiltration/Biostyr, MBBR, SBR via Biogest, Anammox/Anita Mox, oxidation ditch), Tertiary Treatment (Dynasand/Dynacarbon filters, TRITON gravity filters, rotary filters), Micropollutant Treatment (GAC/GAK filtration, ozonation), Sludge Treatment (thickening, digestion, dewatering, thermal hydrolysis, incineration, pasteurization), and Odor Treatment (biofilters, physico-chemical). A flagship proprietary innovation is Membrane Stripping Technology (co-developed with Membratec SA) that recovers ammonia from centrate to produce fertilizer. Equipment partnerships include Nordic Water Products (Dyna series filtration, MEVA pretreatment), Biogest International (SBR), Toray (MBR membranes), and Gorman-Rupp (self-priming pumps). The company also provides services spanning engineering, customer service, welding/assembly, service contracts, operational support, and laboratory analysis.

Expansion highlights6 records

Broad incumbents

• Stantec: Global engineering, architecture, and environmental services firm with a substantial water practice across Europe and North America. Comparable as a broader incumbent targeting the same municipal utility modernization mandates with multi-region scale and broader service breadth.
• AFRY (ÅF Pöyry): Nordic-headquartered global engineering firm with strong Swiss water infrastructure presence (formerly Pöyry and AF-Colenco). Comparable as a much larger incumbent offering full-scope water and wastewater EPC services, in consortium with CSD INGENIEURS on ALPHA-partnered projects.
• WSP Global: Global professional services firm with a substantial water and environment practice in Switzerland. Comparable as a broader incumbent engineering services competitor with deeper international scale — partnered with ALPHA on the Sonceboz Gorman-Rupp pump installation but also competes for primary contractor roles.
• OTV Suisse (Veolia Water Technologies): Swiss arm of Veolia's water technologies business, historically the pioneer of BIOSTYR biofiltration now widely deployed in Switzerland. Comparable as a global water EPC incumbent — partnered with ALPHA on Neuchâtel and La Saunerie renovations but also competes for the same municipal tenders with much greater financial and technological resources.

Direct peers

• CSD Ingenieurs SA: Swiss multi-disciplinary engineering firm with a dedicated water and environment practice. Directly comparable as a co-tendering partner on ALPHA projects (Domdidier biology sanitation, ARA La Saunerie, Sainte-Croix/Bullet ARA La Villette) and as a competitor for municipal wastewater mandates.
• Holinger AG: Swiss engineering firm specializing in water, wastewater, and environmental infrastructure with strong municipal and industrial client base. Directly comparable as an engineering consultancy and ALPHA's consortium partner on multiple GAK filtration and STEP modernization projects (Val-de-Ruz, Sainte-Croix/Bullet, La Saunerie).
• Hunziker Betatech AG: Swiss mid-sized engineering firm focused on water, wastewater, and environmental engineering. Directly comparable as a project delivery partner — collaborated with ALPHA on the ARA Sargans CPS counter-pressure screw installation, and serves overlapping municipal customers across German-speaking Switzerland.
• TRIFORM Engineering: Swiss engineering firm active in municipal infrastructure including wastewater treatment. Directly comparable — partnered with ALPHA on the CHF 5,383,000 Yverdon-les-Bains biology expansion and Penthaz wastewater plant, competing for the same municipal mandates.

Emerging players

• Biogest International GmbH: Germany-based specialist in SBR (Sequencing Batch Reactor) wastewater treatment technology. Comparable as an SBR technology partner offering joint solutions with ALPHA for Swiss and international projects; smaller scope than ALPHA but a focused competitor in the sequencing batch reactor niche.

Others

• Nordic Water Products (Sulzer): Swedish manufacturer of mechanical pretreatment and filtration equipment (DynaSand, DynaCarb, MEVA screens, MevaPress). Comparable as ALPHA's longest-standing exclusive technology partner (30+ years, 100+ installations) — a supplier rather than a competitor, but a critical enabler whose continued partnership underpins much of ALPHA's product portfolio.
