Septage from tanks and pits, safely received, dewatered, stabilised and treated — for towns without sewers and for cities that need more than a sewer network.
More than half the world's urban households are not connected to a sewer; they rely on septic tanks and pits that must be emptied every few years. That septage — faecal sludge — is 10 to 100 times more concentrated than sewage (TS 1–5 %, COD 5,000–50,000 mg/L, high ammonia, helminth eggs and pathogens) and cannot simply be dumped into a sewage treatment plant or a drain.
A faecal sludge treatment plant receives the sludge from vacuum trucks, separates solids from liquid, stabilises and dries the solids into a safe soil conditioner, and treats the liquid fraction to discharge or reuse quality. In India, FSTPs are a core component of faecal sludge and septage management (FSSM) under Swachh Bharat Mission 2.0 and AMRUT 2.0; similar programmes run across Africa and South-East Asia.
KK Enviro Engineers designs and builds FSTPs from 5 to 300 KLD — standalone plants, co-treatment modules at existing STPs, and containerised units for small towns, camps and islands.
Low-energy dewatering and mineralisation for 5–50 KLD; minimal mechanical equipment.
Screw press or decanter for 50 KLD and above, or where land is scarce.
Stabilisation with biogas recovery for larger plants and co-digestion with food waste.
Decentralised anaerobic baffled reactors and constructed wetlands for liquid treatment with near-zero power.
Compact aerobic liquid treatment where land is limited or effluent limits are tight.
Controlled septage receiving station and dosing into an existing STP — the fastest route for cities that already have sewage treatment.
Greenhouse solar dryers or pyrolysis for pathogen-free, saleable end product.
Plug-and-play units for towns, camps and remote settlements.
Inlet characterisation and sampling plan → process selection and mass balance → PFD, P&ID, hydraulic and equipment sizing → civil and mechanical drawings → BOQ, vendor RFQs and procurement → erection supervision → commissioning, performance guarantee test and operator training → operation & maintenance. Delivered as a containerised or skid-mounted package for small and remote sites, or as a site-built turnkey plant for large capacities. Documentation to refinery-grade standards: datasheets, interlock lists, cause-and-effect matrices and O&M manuals your team can actually run the plant from.

From the number of trucks actually arriving per day, not per-capita formulas. A town of 100,000 on septic tanks typically needs 20–50 KLD depending on how many tanks are desludged each year.
Yes — a co-treatment unit with a receiving bay, screening, holding tank and controlled dosing at 1–3 % of STP flow is often the fastest FSSM solution for cities that already have sewage treatment.
0.5–1 hectare for a 20–30 KLD drying-bed plant; 0.15–0.3 hectare for a mechanised or containerised plant of the same size.
