What REWATEC does

REWATEC is the German product brand of Premier Tech Water and Environment GmbH, a wholly-owned subsidiary of Canadian conglomerate Premier Tech Ltd, operating from Boizenburg, Mecklenburg-Vorpommern since 1993. The company designs and manufactures decentralized rainwater harvesting, retention, infiltration, and wastewater treatment systems, plus storage tanks for fire water and drinking water, all based on rotational-molded polyethylene (PE) tanks ranging from 800 to 55,000 liters in flat and cylindrical configurations. Its core proprietary asset is the patent-protected NEOplus flat tank with torus geometry, awarded the German Raw Materials Efficiency Prize in 2019 for achieving up to 35% raw material savings with superior static properties and significantly shallower installation depths.

The product portfolio is organized into three families — rainwater systems (underground/above-ground tanks, complete garden and household systems, retention tanks, sedimentation modules, and Sickeriglu/Sickerbox infiltration), wastewater systems (SBR sequencing batch reactor plants in standard and XL modular variants, Ecoflo energy-free biofilters, and DIBt-approved Sammelgruben collection tanks), and storage tanks (firefighting, drinking water, and universal) — complemented by accessories including filters, submersible pumps, water tap columns, digital S 50 control technology, and the LC 100 wireless overflow detector.

REWATEC sells through a German dealer/handwerker (installer/trade) network, direct B2C website sales with consultation support, direct enterprise sales for municipal and custom projects, and a password-protected B2B customer portal, with optional scheduled, express, and crane/forklift delivery services. Pricing is per unit and varies widely by capacity and system complexity (tanks 580-25,000 EUR, complete household systems up to 26,000 EUR, accessories from 30 EUR), with volume discounts and regional promotional campaigns. Primary customers are private homeowners seeking garden and household rainwater reuse and off-grid households requiring autonomous wastewater treatment, with secondary exposure to municipal/public authorities, commercial/industrial users, and agricultural operations.

Product overview

REWATEC is a product brand under Premier Tech Water and Environment GmbH, specializing in decentralized rainwater and wastewater management systems. The product portfolio is organized into three main categories: (1) Rainwater systems covering utilization (underground/above-ground tanks, complete garden and household systems), retention (retention tanks and shafts), treatment (sedimentation systems), and infiltration (Sickeriglu, Sickerbox systems); (2) Wastewater systems including SBR wastewater treatment plants (with direct aeration, pre-clarification, and XL modular variants), Ecoflo biofilter systems, and collection tanks; (3) Storage tanks for firefighting water, drinking water, and universal applications. The core products are PE (polyethylene) underground tanks ranging from 800 to 55,000 liters, available in flat (Flachtank NEO, F-Line) and cylindrical configurations. Complete systems combine tanks with pumps, filters, controls, and accessories. A diverse range of accessories includes overflow detectors, filters, pump systems, covers, and water extraction solutions. Manufacturing is in Germany (Boizenburg, Mecklenburg-Vorpommern) with 25-35 year warranties on tanks.

• Otto Graf GmbH (GRAF): Germany's largest PE rainwater tank and retention system manufacturer. Directly competes with REWATEC across underground tanks, retention/infiltration systems and accessories for the same homeowner, municipal and dealer channels in Germany.
• Mall GmbH: German manufacturer of concrete and PE stormwater retention, rainwater harvesting and small wastewater treatment systems. Overlaps with REWATEC's retention and Kleinklär­anlagen lines and serves similar municipal and commercial customers.
• WISY AG: German rainwater harvesting specialist (filters, vortex fine filters, complete systems). A direct competitor in the same decentralised rainwater harvesting category served by REWATEC.
• Fränkische Rohrwerke (FRÄNKISCHE): German family-owned manufacturer of plastic pipe, drainage and water management products, including rainwater and infiltration solutions. Overlaps with REWATEC's rainwater/infiltration portfolio for builders, dealers and municipalities.

Emerging players

• Intewa GmbH: German provider of rainwater harvesting, greywater recycling and infiltration systems. Smaller and more niche than REWATEC but offers overlapping decentralised water solutions to homeowners and commercial projects.

Others
