Standard RO purifiers waste 3 to 4 liters of water for every 1 liter of drinking water produced and strip out all natural alkaline minerals like calcium and magnesium. Shrunga’s tap water filtration lineup operates with 100% zero water wastage, requires no electricity, preserves natural mineral balance, and eliminates suspended silt, pipeline rust, free chlorine, heavy particulate matter, and chemical odors.
No, it actively preserves natural minerals. Demineralized water is slightly acidic and flat in taste. Our multi-stage activated carbon and micro-porous filtration targets impurities, chemicals, and particulates while allowing healthy bio-available calcium, magnesium, and potassium ions to remain intact, resulting in crisp, natural, alkaline-tasting drinking water.
Under typical Indian household usage (15 to 25 liters daily), a cartridge lasts between 6,000 and 10,000 liters—approximately 6 to 12 months. Cartridge replacement is 100% tool-free DIY: simply twist off the spent cartridge and snap the fresh one into place in under 60 seconds without needing a technician or plumber.
No electricity or booster pumps are required. The systems operate on standard gravity pressure from your overhead water tank or municipal distribution line (0.5 to 4.0 bar). They can be mounted directly to your kitchen tap, installed neatly under the sink, or fitted inline before your kitchen storage.
Yes. By capturing monsoon rooftop runoff and surface drainage and injecting it through dual-stage filtration chambers directly into the deep geological fractures around your borehole casing, we create a localized hydraulic pressure head. This stored underground reserve sustains static water levels throughout harsh summer months when surrounding uncharged wells run dry.
No. Our recharge chambers use a two-step settlement mechanism: a high-capacity silt desilting pit followed by an engineered non-clogging V-wire wedge screen and gravel bed. The fine V-wire geometry deflects suspended sediment particles while allowing only clean water to inject into the casing. It fully complies with Central Ground Water Board (CGWB) guidelines.
Yes. Rainwater has near-zero TDS (typically 10 to 30 ppm). Injecting hundreds of thousands of liters of rainwater directly into the subterranean aquifer dilutes the concentration of deep subterranean salts, fluorides, and carbonates, resulting in noticeably softer water and a substantial reduction in TDS over consecutive rainy seasons.
A standard residential or RWA borewell recharge system requires an underground excavation of approximately 6 ft x 6 ft x 8 ft near your borewell or stormwater line. The entire chamber is subterranean and finished flush with the ground using heavy-duty cast-iron or RCC manhole covers, allowing vehicles or foot traffic above without losing open space.
AWGs replicate nature’s rain cycle indoors. The machine draws ambient air through medical-grade HEPA filters to scrub all airborne dust, allergens, and micro-particles. It then chills the air below its dew point using an optimized thermodynamic cycle, condensing moisture into pure liquid drops. The collected water undergoes multi-stage UV sterilization, activated carbon filtration, and active bio-mineralization before dispensing.
Visakhapatnam, Kakinada, and coastal Andhra Pradesh are among the best locations in the world for Atmospheric Water Generators. With year-round relative humidity consistently between 60% and 85% and warm ambient temperatures, AWGs achieve peak output efficiency and the lowest power consumption per liter.
Under coastal conditions (humidity > 65%), our MEGHDOOT systems by Maithri Aquatech consume approximately 0.25 to 0.35 kWh of electricity per liter of water generated. When paired with rooftop solar panels in homes, resorts, or industrial campuses, the operating cost drops to near zero.
Yes, 100%. Because atmospheric water never touches polluted soils, agricultural pesticide runoff, or rusting pipeline networks, it is inherently free from heavy metals, arsenic, nitrates, PFAS, and microplastics. The water strictly exceeds WHO, US EPA, and Bureau of Indian Standards (BIS 10500) drinking water quality benchmarks.
Tap filter hardware carries a 1-year replacement warranty, AWG machines come with 2 to 5 years manufacturer compressor and electronic warranty, and Bore Well Recharge assemblies feature high-grade stainless steel V-wire screens engineered for 15+ years of operational life. Our engineering team provides annual pre-monsoon checks and on-site support across Andhra Pradesh and Telangana.
Yes. For borewell recharge projects and large-capacity commercial AWG deployments, our hydrogeological team provides free site feasibility surveys in Visakhapatnam, Kakinada, Rajahmundry, Vijayawada, and Hyderabad. Simply message us on WhatsApp at +91 95159 35851 with your location.
