Ganesh Visarjan and Our Water: Celebrating Without Harming the Source

Ganpati Bappa Morya! Ganesh Chaturthi is here, and with it ten days of aarti, modak, flowers, music and family gathered around the pandal. It ends with visarjan on Anant Chaturdashi, when we walk Bappa to the water and ask him to come back early next year.

There is one quiet fact worth remembering on that walk. The lake, tank or river we return Bappa to is the same water that comes back to our taps and borewells. Caring for it is part of the same respect we show the festival.

Why the material of the idol matters

For generations, Ganesh idols were made of unbaked clay from the local riverbank or tank bed. When immersed, the clay softened and dissolved back into the water within hours. The idol came from the water and returned to it, complete.

Plaster of Paris changed that, for understandable reasons. It is light, cheap, sets quickly and lets artisans make tall, finely detailed idols. Nobody chose it to harm anything.

The difference is what happens after immersion. Plaster does not dissolve properly. It hardens in water and can sit on a tank bed long after the festival is over.

What actually enters the water at visarjan

An idol is rarely immersed alone. Along with it, the water usually receives:

• Undissolved plaster that settles as sediment on the bottom.
• Synthetic paints and varnish, some using metal-based pigments for bright, lasting colours.
• Thermocol and plastic decorations that float, break into pieces and do not break down.
• Cloth, thread and jewellery from the dressing of the idol.
• Flowers, garlands and food offerings, often still in plastic bags.

In plain terms, the water turns cloudy. Rotting flowers and food use up the oxygen that fish need. Sediment builds up on the tank bed and stays. Some of what dissolves moves slowly into the shallow groundwater nearby. Several of these are the same common water impurities that purifiers are built to handle. Families on borewell water near a tank notice it first.

Why it comes back to us

Lakes and tanks are not separate from our drinking water. They soak slowly into the ground and recharge the shallow aquifer around them. A borewell dug within walking distance of a tank draws from that same layer.

Borewell water already carries its own share of the ground it passes through, which is why iron stains and hardness are so common. Festival residue adds to that load.

Many towns that immerse idols in a local tank also draw drinking water from close by. This is the honest reason to care. It is not about blame. The water simply goes in a circle, and we are standing on the circle too.

Idol and offering choices

Eco-friendly options that are easy and traditional

The kindest choices are also the oldest ones.

• Shadu (unbaked clay) idols are widely available and are what our grandparents worshipped.
• Natural colours such as turmeric, geru, kumkum and vegetable dyes give a warm, traditional look.
• A small idol for the home is easier to immerse, easier to carry and needs less material.
• Seed idols hold a few seeds inside the clay. Immerse one in a pot of soil, and a plant grows where Bappa was.
• A permanent metal or stone idol, worshipped every year and given a symbolic visarjan. Many families already do this, and the devotion is exactly the same.

How to do a safe home visarjan

Home immersion is simple and keeps the festival close to the family.

• Use a bucket, drum or large vessel of clean water. Do not use the drum you store drinking water in; our guide on how long stored water stays safe explains why.
• Remove cloth, thread, jewellery, plastic and thermocol before immersion.
• Keep flowers and food offerings out of the vessel. Compost them or give them to a nirmalya collection.
• Let a clay idol dissolve fully, which may take a day or two.
• Pour the settled clay water onto plants, trees or a garden bed, not down the drain. Clay is soil, and the garden welcomes it.
• One honest note: if the idol was plaster or painted with synthetic colours, do not pour the residue into the garden or the drain. Bag it and hand it to the municipal collection point.

Use the civic arrangements

Most cities and towns, including Bengaluru and Hosur, set up designated immersion tanks, mobile tanks on trucks and nirmalya collection points during the festival. They catch the sediment, paint and offerings before any of it reaches a natural lake.

Using them is not a compromise; the aarti and the final farewell are the same. The only difference is that the load stays out of the tank your borewell drinks from. Ask your ward office or residents’ group for the arrangement nearest you.

Small things that add up

• Choose a smaller idol than last year.
• Use fewer plastic decorations, and take home the ones you do use.
• Carry offerings in cloth bags instead of plastic.
• Compost the nirmalya offered during the ten days.
• Take a few minutes to clean the immersion spot after the farewell.

None of these change the festival. All of them change the water.

Bottom line

Ganesha is the remover of obstacles. A cloudy lake is one obstacle we can remove ourselves, with the same hands that offered the modak. That is a fine way to honour him.

Since the same water comes back to us, know what is in the glass you drink from. Test your TDS, read our guide to the best TDS level for drinking water, and let our RO vs UV vs UF buying guide point you to the right purifier. If the answer is RO, the LUXGEN Royale Copper is one we are happy to recommend.

Ganpati Bappa Morya. Pudhchya varshi lavkar ya, and may the lake be cleaner when you return.
