STP solutions

STP for apartments and residential towers

Apartment associations pay for their STP every month — in electricity, operator wages and sludge disposal. A plant that is simpler to run keeps those bills down for years.

The short answer

Aquatron removes sludge handling and, per published details, needs no dedicated operator up to 500 KLD. Voora’s Ocean 27 in Chennai runs a 110 KLD Aquatron STP. 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 are apartment STP running costs so high?

Conventional plants run blowers and pumps continuously, need operators and produce sludge that must be removed. Aquatron separates solids first, and published comparisons show up to 65% less electricity and up to 80% lower OPEX.

Can an existing apartment STP be upgraded?

India Water Systems offers retrofit assessments for underperforming STPs. Feasibility depends on the existing layout, plumbing and flow; see the retrofit feasibility guide.

How is apartment STP capacity worked out?

Capacity is based on actual or designer-approved daily wastewater flow. 1 KLD equals 1,000 litres per day. See the capacity calculation guide.

Is there a residential project example?

Voora’s Ocean 27, a residential tower in Chennai, uses a 110 KLD Aquatron STP. More projects are listed on the references page.

Does the association still need an AMC?

Yes. Aquatron is low maintenance, not maintenance-free. Agree a written AMC covering the bio-chamber, filters, UV and water-quality testing.
