STP solutions

STP for malls and commercial buildings

Malls and commercial buildings need a sewage treatment plant that fits a crowded basement, copes with busy and quiet hours, and does not demand a full-time operating crew.

The short answer

Aquatron separates toilet solids at the start, so the plant needs no sludge pump, press or disposal trips. Published comparisons show about 60% less built-up space, up to 65% less electricity and up to 80% lower OPEX. Figures are indicative comparisons against a conventional STP of the same capacity, not a quotation or guaranteed result. Final design, cost and performance depend on a site assessment.

Buyer questions, answered

Why does space matter so much for a mall STP?

Basement and service areas in commercial buildings are valuable for parking, storage and plant rooms. Because solids are separated before treatment, an Aquatron layout avoids sludge-handling equipment; the published comparison claims about 60% less built-up space than a conventional STP of the same capacity. The designer must confirm the complete layout for your site.

Can the plant handle uneven footfall?

Commercial sewage flow varies with opening hours, events and seasons. Give the designer occupancy figures, peak periods and future expansion plans so the plant is sized for real conditions, not a generic rule. See the STP capacity calculation guide for how flow is estimated.

Do we need an operator on site?

The published Aquatron details state that no dedicated operator is needed up to 500 KLD. Routine checks of the bio-chamber, filters and UV remain necessary. Larger plants can be supported through India Water Systems O&M services.

Can treated water be reused in the building?

The complete system filters and UV-disinfects the separated liquid for reuse such as flushing, gardening and chiller make-up. Reuse quality targets should be agreed in writing for your site and confirmed by testing.

Which commercial projects use Aquatron®?

Published project examples include WeWork BlueOne Square in Gurgaon (50 KLD retrofit) and Arun Jaitley Cricket Stadium (380 KLD). We do not list a named mall project on this site; ask us for references that match your building type.
