Hyderabad Flushes 1,950 Million Litres a Day. Where Does It All Go?
Every day, we flush toilets, take showers, cook food, and wash dishes. All that dirty water immediately disappears down the drain. But in a fast-growing city like Hyderabad, handling this huge amount of wastewater is a massive operation. When any pipe gets choked, a septic tank fills up, or a sewer backs up, it quickly turns into a terrible day for a family, an apartment society, or a restaurant.
This simple guide explains where all the wastewater goes, what official government records say, why metro drains get blocked, and what you should do before an overflow happens.
1. The Real Numbers Behind Hyderabad's Sewage
Hyderabad's urban area produces around 1,950 million litres of sewage every single day (MLD). About 1,650 MLD comes from inside the main municipal limits, and another 300 MLD comes from areas around the Outer Ring Road (ORR). The government has been building new Sewage Treatment Plants (STPs) quickly, but the city is expanding even faster.
| Sewage Metric | Capacity / Generation (MLD) | What It Means |
|---|---|---|
| Generated daily | 1,950 MLD | Total wastewater produced daily across Hyderabad and the ORR belt |
| Capacity in 2021 | 772 MLD | Treated only about 46% of sewage produced in city limits |
| Capacity in 2024 | 1,338 MLD | Increased capacity after several new STPs opened |
| Planned capacity | 1,791 MLD | Target capacity for upcoming government plants |
Remember, treatment plants only help if sewage lines actually connect to your building. Official government compliance reports submitted to the National Green Tribunal (NGT OA No. 606 of 2018) noted that outer areas along the ORR have only partial sewer connections. That means popular growth areas — such as Madhapur, Gachibowli, Tellapur, Kokapet, Kondapur, and Kollur — still depend heavily on private septic tanks, soak pits, and building drains that property owners and apartment committees must clean regularly.
2. Why City Life Makes Drainage Problems Worse
In a crowded metro city, underground pipes face heavy daily stress. Here are 4 main reasons why drains choke so easily in Hyderabad:
🏢 1. High Density Living
Modern high-rises and gated communities place hundreds of families on a single septic tank or STP. Sludge builds up much faster than in independent villas.
🌧️ 2. Monsoon Surges
Heavy rains flood stormwater drains. Mud and street silt wash backward into building sewer lines, causing sudden blockages.
🍳 3. Kitchen Oil & Grease (FOG)
Restaurants, canteens, and home kitchens pour cooking oil, ghee, and fats down the sink. When hot grease cools in the pipes, it solidifies into hard wax-like plugs that block water completely.
🚗 4. Basements & Underground Parking
Underground parking levels (B1, B2, B3) sit at the lowest point. When mainline pipes get choked, sewage water pushes back into cellar floor traps first.
3. 5 Warning Signs That Your System Needs Immediate Cleaning
Underground drainage systems almost always give warning signals days before dirty water overflows into your home. Look out for these 5 common signs:
- Slow Draining Water: Water drains slowly in more than one bathroom or kitchen sink.
- Gurgling Bubbles: Gurgling or bubbling sounds coming from toilet bowls or floor traps.
- Bad Smells: Foul, rotten odor near the septic tank cover, garden, or parking lot.
- Soggy Ground: Wet, spongy soil or unusually dark green grass growing right over your septic tank.
- Dirty Backflow: Dirty water pushing back up in ground floor or basement drains when upper floors use water.
4. How Much Does Prevention Cost?
Regular preventive cleaning costs very little money compared to repairing damaged flooring, repainting walls, or shutting down a commercial kitchen after an overflow. Here are Dial-a-Septic's clear starting rates:

5. How Often Should You Clean Your Septic Tank?
Solid sludge builds up slowly at the bottom of your septic tank. Cleaning your tank on time keeps healthy bacteria working and prevents solid waste from choking your soak pit or drainage lines:
| Type of Property | How Often to Clean* | Why This Matters |
|---|---|---|
| Independent house / villa | Every 2 to 3 years | Depends on your tank capacity and family size |
| Apartments & gated societies | Inspect every year | Clean whenever sludge levels rise (usually every 6 to 12 months) |
| Restaurants & food kitchens | Every month | Busy kitchens produce heavy oil and grease that can choke mainlines quickly |
| Basements & sump pits | Before monsoon & after any backflow | Ensures sump pumps and drainage pits have 100% free capacity for rains |
*General industry guidance. Your tank size and daily water usage decide the real cleaning interval. Our field team can inspect and guide you on-site.
