Choosing the Right Sump Tank Size for My Home – A Thoughtful Decision

As we begin building our dream home in BSK 6th Stage, 4th Block, one of the earliest and most important choices we made was about the sump tank size. It might seem like a small decision in the grand scheme of things, but water is such a basic necessity—it deserves thoughtful planning

We are a family of 4 to 5 people, and I wanted to make sure we had enough water storage to last comfortably for at least 12–15 days, even during dry spells or BWSSB delays. After some thinking and observing how things work in Bangalore, I decided on a 8,000-litre sump. This is a practical size—tankers like Tata 709 and tractors that commonly deliver water in this area usually carry around 6,000–7,000 litres, so this capacity fits well.

At our site location, the Kaveri water connection is in progress So, hopefully, the connection will be available soon. Until then, tanker water is our backup plan.

Now, you might wonder—why not drill a borewell? Here's the thing: BSK 6th Stage was once a Turahalli Forest area, and even now it still has that green, peaceful vibe . I didn’t want to disturb the ground by drilling a bore unnecessarily. Also, borewells come with extra electricity costs. So I felt it was better to avoid it.

Coming to the construction side, my structural engineer recommended using 8-inch blocks for the sump walls, given the 7K–8K litre capacity. If the tank was below 4,000 litres, 6-inch blocks would have been okay. It's good to go with expert advice when it comes to structural safety.

Right now, the sump work is in progress, and things are moving along steadily.

Building a home is not just about cement and bricks—it’s about the little choices we make every day that will impact how we live for years to come. Choosing the right sump size may seem like a small thing, but it's one step closer to creating a sustainable, comfortable home
