What does a 1 MLD STP cost?
Indicative CAPEX: Aquatron ₹5.14 Cr, MBR ₹7.61 Cr, SBR ₹8.24 Cr, MBBR ₹9.15 Cr. See the full STP cost guide.
The cheapest STP to buy is often the most expensive to run. Look at the full cost over the plant’s life: build cost, electricity, operators, sludge disposal and maintenance.
The short answer
Against a conventional STP of the same capacity, published comparisons show about 35% lower project CAPEX, 65% less electricity, 80% lower annual OPEX and 60% less built-up space. 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.

In the published 75 KLD villa example, Aquatron costs ₹88.9 L against ₹1.64 Cr, with AMC of ₹3.2 L against ₹15 L.
No power in the separation stage, no sludge disposal and, per published details, no dedicated operator up to 500 KLD.
Compare on treatment targets, design life and service support, not price alone. Aquatron has a published 50-year design life.
