Our services — licensed septage, sanitation, and drainage across Ernakulam
Chinnadan Septic Services handles every sanitation task common to Kerala homes and businesses — from a single residential septic tank cleanup to monthly STP maintenance for a 40-unit apartment complex in Kakkanad. Every job is performed under Kochi Municipal Corporation License KMCSW2025133, with corporation-approved pricing, licensed disposal at designated sites, and a GST-compliant invoice on completion.
Septic Tank Cleaning
Full residential and commercial septic tank cleaning with vacuum tanker.
Residential and commercial septic tanks across Kochi and Ernakulam are cleaned using our Kochi Municipal Corporation-licensed vacuum tanker (Mahindra, KL-45-L-9677, below 6000L capacity). We handle routine maintenance, emergency overflows, and pre-monsoon preventive cleaning.
What's included
- Arrival, tank location, and access assessment
- Full sludge and liquid extraction with vacuum tanker
- Tank inspection for cracks, root intrusion, and baffle damage
- Surface cleaning and sealing of the access cover
- Licensed disposal at Corporation-designated sites
- GST-compliant invoice with our KMC license number
Pricing
Residential septic tank cleaning is priced at the corporation-approved maximum of ₹4,500 per load. Commercial and apartment customers qualify for volume discounts.

Soak Pit Cleaning
Residential and commercial soak pit service and inspection.
Soak pits are a separate system from septic tanks — they handle the liquid effluent after solid separation. A failing soak pit is often the hidden cause of “the septic tank keeps overflowing.” We clean residential and commercial soak pits across all our service areas.
What's included
- Soak pit access and safety check
- Liquid and sediment extraction
- Pit wall and base inspection for damage or collapse
- Restoration recommendations if the pit is failing
- Cleanup and site restoration

STP Maintenance
Apartment complex and commercial sewage treatment plant maintenance.
Sewage Treatment Plant (STP) maintenance keeps apartment complexes, commercial buildings, and gated communities in Kochi and Ernakulam compliant with Kerala Pollution Control Board norms and resident expectations. Chinnadan services STPs ranging from 10 KLD (small apartment blocks) to 150+ KLD (large residential complexes and commercial parks) across all seven of our service areas.
What's included
- Scheduled desludging of settling and aeration tanks
- Biological media inspection and bacterial dosing
- Pump and blower health check with performance logs
- Odour control and chemical dosing calibration
- Discharge water quality visual check and sample collection
- Compliance log for building associations and audits
- Licensed sludge disposal at Corporation-approved sites
AMC contracts available
Monthly, quarterly, and annual STP maintenance contracts are available for buildings of 20+ units. Contract pricing typically works out significantly cheaper than per-visit billing — and gives residents a predictable schedule. Call +91 62388 04932 for an on-site assessment and quote.

Sewage Tank Cleaning
Large-capacity sewage tank cleanup for apartments and institutions.
Sewage tank cleaning covers the larger holding, pumping, and sump tanks found in apartment complexes, hostels, hospitals, hotels, and institutional buildings across Kochi and Ernakulam. These tanks handle significantly higher volumes than residential septic systems — a single apartment block's sewage sump may hold 10,000 to 50,000 litres, and overflow events risk basement flooding, equipment damage, and health hazards.
What's included
- Pre-service site survey — access, confined-space clearance, residents notification
- Full liquid and sludge extraction with our vacuum tanker
- Tank wall inspection for cracks, root intrusion, or baffle damage
- Pump chamber cleaning and float-switch check
- Odour neutralisation and surface disinfection on completion
- Licensed disposal at Kochi Corporation-approved sites with manifest
- GST-compliant invoice with KMC license number for building records
Emergency and scheduled service
We handle both scheduled sewage tank maintenance (quarterly / half-yearly) and emergency overflow response — 24 hours, every day across Vyttila, Maradu, Kakkanad and all our service areas. Multiple-load jobs and oversized tanks are quoted after an on-site assessment.

Grease Trap Cleaning
FOG interception and trap cleaning for restaurants and hotels.
Restaurants, hotels, hospital kitchens, catering operations, and food courts in Kochi are required to install and regularly maintain grease traps (FOG interceptors) under Kerala Pollution Control Board norms and Kochi Corporation drainage bylaws. A poorly maintained grease trap causes drain blockages, foul odours, kitchen downtime, and — most seriously — penalty notices from the Corporation.
What's included
- Full extraction of accumulated fats, oils, grease, and food solids
- Interior wall scraping and high-pressure wash of baffles
- Inlet and outlet pipe check for grease build-up
- Trap re-filling with clean water and operational handover
- Service log entry for your FSSAI / Corporation compliance file
- Scheduled visits — weekly, fortnightly, or monthly depending on kitchen volume
- Licensed grease waste disposal — no illegal drain discharge
Commercial AMC rates
Most of our restaurant customers are on monthly or fortnightly contracts, which keeps the kitchen draining smoothly and provides a documented compliance trail. We're happy to assess your trap size and kitchen volume, then quote. Call +91 62388 04932 or WhatsApp for a site visit.

Drain & Sewer Cleaning
Blocked drains and sewers cleared with jetting and vacuum extraction.
Blocked kitchen drains, slow bathroom flows, backed-up external sewer lines, and manhole overflows are among the most common calls we take — often as 24-hour emergencies. Chinnadan clears residential and commercial drains across Vyttila, Maradu, Thrippunithura, Udayamperoor, Mulanthuruthy, Chottanikkara, and Kakkanad using vacuum extraction and, where needed, manual rodding.
What's included
- Diagnosis of the blockage location and probable cause
- Mechanical clearance of accessible blockages (hair, grease, debris, roots)
- Vacuum extraction of standing sewage and backed-up water
- Sewer line flushing to restore normal flow
- Visual inspection of exposed line sections for cracks or collapse
- Recommendations if a deeper structural issue is likely (collapsed line, root ingress)
- Site cleanup and disinfection on completion
Common underlying issues
A persistent kitchen or bathroom blockage is frequently a symptom of a full septic tank, a failing soak pit, or a collapsed outer sewer line — not just a clog at the fixture. We'll tell you honestly if the drain cleaning is a short-term fix versus if the tank needs cleaning or the soak pit needs restoration. Call +91 62388 04932 for a same-day visit.
