WAAW Mall — Irinjalakuda, Kerala
WAAW Mall atrium approach — Irinjalakuda, Kerala

Sustainability

Green is engineered.

Rainwater tanks on the site plan. Treatment loops in the utility schedule. Open space on the plot. Here is what is actually built into WAAW Mall — not what is claimed about it.

Approach

Six systems. All on the drawings.

  1. 01

    Rainwater, captured

    A 34,650-litre underground rainwater harvesting tank — sized well above the required 32,100 L — catches monsoon run-off from the roof via a filtered downpipe network. That water runs the mall's landscape and washdowns instead of drawing from municipal supply.

  2. 02

    Wastewater, treated on site

    A bar-screened, multi-stage STP (equalisation → aeration → final settling → treated-water reservoir) handles every litre the mall produces. Treated water is re-used for flush and irrigation. The municipal drain sees a fraction of what a mall of this size typically discharges.

  3. 03

    Fire + water, engineered in

    10,000 L overhead potable tank and a dedicated 30,000 L overhead fire tank sit on the terrace plant deck. Fire stairs and refuge cores on every floor. Compliance built at design stage, not retrofitted.

  4. 04

    Daylight before downlight

    A 3.5 m wide open passage and a triple-height atrium cut pull daylight through the retail plate. We mechanically ventilate the back-of-house and let the front-of-house breathe.

  5. 05

    50% open on the plot

    Of 1,933 m² of site, more than half stays as open space, driveway and planting. Paving is permeable where it can be, so the ground keeps drinking rain.

  6. 06

    Designed to age well

    Materials specified for decades of daily footfall — not just for the opening-week photograph. Services are laid out so future upgrades (EV charging, rooftop solar) land without tearing the building open.

Targets & status

Honest numbers, honestly labelled.

  • Rainwater harvesting

    in place

    34,650 L underground tank with filtered collection — 108% of the statutory requirement.

  • On-site STP

    in place

    Primary + aeration + settling + reuse loop. Treated-water bus for flush, irrigation, washdowns.

  • Open space on plot

    in place

    ≈50% of the 1,933 m² site retained as open space, driveway and planting.

  • EV charging provision

    on the path

    Basement and terrace decks are laid out so EV charging bays can be commissioned without civil work.

  • Rooftop solar ready

    on the path

    The terrace plant deck is structurally and electrically set up for a future PV install.

Our commitment

Green is engineered, not advertised.

We'd rather publish the rainwater tank spec than a logo. Everything above is on the sanctioned drawings — if you want to see the permit, ask.
