For Homes & Communities
Softeners, drinking-water systems and whole-house filtration designed for skin, hair and the everyday comfort of your family.
For: Villa Communities · Individual Homes · Health-conscious Families
Dedicated softeners and filtration for every villa. Consistent water quality across the entire estate — no shared dependency, no compromises.
Centralised WTPs deliver soft water to every floor. Compact STPs recycle wastewater for flushing and landscaping — cutting tanker bills and freeing up space.
24×7 WTPs for spotless linens and scale-free showers. Lab-grade purity for hospitals. Quiet, compliant STPs that keep operations running and regulators satisfied.
WTPs engineered for exact conductivity and purity specs. ETPs and ZLD-ready systems that maximise reuse, shrink freshwater intake, and keep compliance costs predictable.
The Real Problem with STPs & WTPs
Buildings inherit STPs and WTPs that occupy too much space, cost too much to run and produce water no one wants to reuse. We design plants that do the opposite — compact, quiet, low-OpEx, and producing treated water clean enough to behave like utility water from day one.
Soft water, every tap
Get a no-obligation water consultation. We assess output quality, space usage, power and chemical consumption — then show you exactly where money and water are leaking.
Book a Professional AuditConventional sewage plants consume large basement or setback area that could be parking, landscape or saleable space.
Oversized, generic STP/WTP designs inflate civil cost upfront and power, chemical and manpower cost for life.
Plants that demand daily babysitting fail the moment a skilled operator leaves the site.
Poor process design produces water that smells or stains — flushing, gardening and cooling reuse never happens.
Hardness, iron, TDS and pressure issues damage plumbing, geysers, boilers and resident experience.
PCB norms, society audits and ESG reporting expose poorly designed or undocumented plants.
Core Solutions
Our portfolio is built around two anchors — large Water Treatment Plants engineered for reliable utility-grade output, and innovative, space-saving Sewage Treatment Plants that turn waste into reusable water early in the process. Around them sit the supporting systems your site actually needs.
Book a free on-site water consultation. Our specialist will assess your source water, existing plant and usage pattern — then recommend the right combination of WTP, STP, softener or home package.

Specialised
Premium hydrogen water, dialysis and lab-grade systems with validation and documentation.
Revolutionary source-separation technology that eliminates toxic sewage sludge, slashes space requirements, and seamlessly converts your wastewater into reusable water.
Utilizing the natural momentum of flushing water, gravity, and centrifugal force, our system instantly separates 98% of liquids from solid waste at the entry pipe — with zero moving parts and zero electricity.
Separated solids drop directly into an isolated bio-chamber. Within weeks, natural aerobic decomposition converts waste into a minute volume of dry, completely odorless, hygienic manure — eliminating vacuum tankers entirely.
Because the liquid stream enters our treatment cells completely free of heavy organic solids, complex biological aeration is bypassed. Standard modular filtration with UV/Ozone disinfection instantly recycles water back to PCB/NGT flushing and irrigation standards.
Our engineers can map this modular physical separation system directly into your existing architectural blueprints or building downtakes.

Our Story
India Water Systems began when our founders were searching for a water treatment solution for their own home and discovered how hard it was to get honest, accurate advice. Most sellers offered products. Almost no one offered clarity.
That experience revealed a deeper truth: access to safe water is not just a product problem. It is a public health problem, a trust problem, and a long-term maintenance problem. Most people do not know what contamination they are dealing with, which solution fits their situation, or whom they can rely on for unbiased guidance.
Instead of becoming another equipment vendor, the founders built a solution-led company — one that diagnoses first, designs around real constraints, and stays accountable after installation. What started as a mission to fix one home has grown into a commitment to deliver dependable water infrastructure across homes, apartments, institutions, industries and underserved communities.
To make safe, clean water accessible to every household, institution and community that needs it — through honest engineering, transparent partnerships and lifetime support.
Through CSR and institutional outreach, the IWS team is expanding access to safe drinking water in government schools, rural areas and public-use spaces across India.

How We Work
We diagnose before we prescribe. Every recommendation starts with understanding your water, not pushing a product.
A plant that is installed and forgotten fails. We design for maintainability and stand by it with AMCs and genuine spares.
No hidden costs, no oversizing, no scare tactics. We earn trust through honest advice and reliable execution.
Why India Water Systems
Real estate, capital cost, operating cost and operator dependency — every WTP and STP we design is judged against these four before we commit a single drawing.
Our compact STPs and WTPs free up basement, setback and rooftop area — recovering real estate you can actually use.
Right-sized civil, lower power draw, fewer chemicals and minimal manpower — the plant pays for itself in operating savings.
We engineer STPs so treated water behaves like utility water from the first stage — usable for flushing, gardens and cooling without afterthought.
Designed for automation and stability, our plants survive operator turnover and routine neglect without compliance scares.

Plant Audits & Consulting
Most buildings are running plants that were either oversized at design stage or are silently underperforming today. A short, structured on-site audit tells you where space, money and water are leaking — and what a smarter plant would look like.
Water audits for WTPs and STPs are charged professional services conducted by certified specialists. They are not the same as the free initial water consultation we offer for home and residential enquiries. A full plant audit follows IS 17650:2021 standards and delivers a documented, compliance-ready report.
Why professional water audits matter — per the Water Audit Council of India (IPA initiative):
Plant Performance
Measured & Verified
Our solutions are shaped by actual site conditions, real water challenges and systems designed for long-term performance.
Case StudyA residential community facing high hardness and scaling issues required a centralised treatment solution. We designed an appropriate softening system that improved water usability and reduced maintenance concerns across the property.
Case StudyA facility with a steady need for purified water required a robust and practical solution. We proposed a commercial RO setup designed for dependable output and operational ease.
Case StudyA building project required wastewater treatment support aligned to its usage and compliance needs. Our team designed a suitable STP approach focused on treatment performance and ease of operation.
From homes to institutions to commercial facilities, our clients value solutions that are technically sound, practically designed and responsibly delivered.
