Hosur has grown from an industrial town into one of Tamil Nadu's busiest manufacturing and residential hubs. Automobile, auto component, electronics and precision engineering plants fill the SIPCOT estates, while apartments and gated communities spread along Bagalur Road, Rayakottai Road and towards the Bengaluru border as people choose Hosur for its lower costs. Every factory canteen, worker hostel, apartment block, hospital and school here generates sewage that must be treated. Intellect Aqua designs, builds and maintains sewage treatment plants (STPs) for Hosur, sized for real flows and space.
Whether you need a new plant, an upgrade or a team to run your existing STP, we cover design, installation, commissioning and long-term maintenance.
Hosur's rapid growth has outpaced its water supply. Many factories and apartments depend on deep borewells and tankers, and groundwater in parts of Krishnagiri district is hard and can carry fluoride. At the same time, pollution of local lakes and the Thenpennai river from untreated sewage is a growing concern. A well-designed STP meets discharge norms and lets you reuse treated water for flushing, gardens and cooling towers — reducing dependence on tankers.
Large manufacturing plants in SIPCOT Phase I and II run multiple shifts with thousands of workers, big canteens and sometimes on-site accommodation. Their sewage peaks at shift changes and meal times. We design factory STPs with:
Many Hosur plants supply global automobile and electronics brands that audit their suppliers' environmental performance. A well-run STP with proper records supports these audits. Process wastewater from painting, plating or washing goes to a separate ETP.

Hosur's residential boom means many new projects need STPs that run quietly, do not smell and keep maintenance charges reasonable. Packaged MBBR plants suit most projects; MBR suits premium projects and tight basements. We plan ventilation, sludge access and dual plumbing so reuse actually happens.
Hospitals need continuous treatment with standby equipment and disinfection. Schools and colleges need plants that handle holiday low-flow periods — SBR or flexible MBBR designs work well.
We size on actual users — workers per shift, hostel residents, flats or beds — and add margin for peaks and growth. As a guide, residential sewage is about 0.5 KL per flat per day. For factories, we look at shift patterns and canteen meals served.
In Hosur, reuse is where an STP pays back. Treated water, after filtration and disinfection, can supply flushing, gardens, landscaping and cooling towers. For drinking water, pair the STP with an RO plant — important where fluoride is present.
Overloaded plants after workforce or occupancy growth, clogged diffusers, sludge not removed, odour in basements and untrained operators are common issues. We audit, repair and upgrade — often within existing tanks — and keep plants stable through an AMC.
Cost depends on capacity, technology, construction type and reuse quality. See our STP cost guide. We give an exact quote after a free site visit, including monthly running cost.
For new factories and apartment projects, the best time to plan the STP is at the drawing stage. We work with your architect or plant engineer to fix the STP location, tank sizes, ventilation, sludge removal access and reuse lines before construction starts. Early planning avoids costly changes later, keeps the plant away from living and working areas, and makes approvals smoother. We also prepare the STP details required for building plan and consent applications.
Our AMC service provides operators, routine checks, sludge management, chemicals, spares, testing and audit-ready records.
We serve Hosur and Krishnagiri district — SIPCOT Phase I and II, Mathigiri, Zuzuvadi, Bagalur Road, Rayakottai Road, Alasanatham, Shoolagiri, Kelamangalam, Denkanikottai, Thally, Krishnagiri and Bargur.
We also build STPs in Chennai, Ranipet, Salem and Coimbatore.
