The Problem
-
Fragmented vendors, broken accountability
Separate firms for engineering, civil work, chemicals, and IT create gaps, delays, and blame-shifting — leaving your project stalled and your DoE deadline unmet.
-
DoE and BNBC compliance pressure
Bangladesh's Department of Environment and national building codes impose strict effluent discharge standards — non-compliance risks shutdowns, fines, and export market access.
-
EU buyer sustainability requirements
Export markets increasingly audit factory water treatment. Garment buyers and international brands demand documented ZLD or STP performance as a condition of orders.
Our Approach
-
One firm, six disciplines — full accountability
Hydro Engineering Solutions covers ETP, STP, WTP, RO, MLD, and ZLD engineering plus civil construction, industrial chemicals, and SCADA/IT monitoring — all under a single contract.
-
Designs engineered for DoE approval
Every system is designed to Bangladesh DoE discharge standards from the first drawing — so your approval process is predictable, not a rework cycle.
-
Documented performance for buyer audits
We provide full operational documentation, effluent quality data, and system performance reports formatted for international sustainability audits and EU buyer requirements.
Our Disciplines
Six engineering specialisms.
One integrated team.
No discipline is a bolt-on. Each is engineered by specialists and integrated by a single project team — so handovers between systems never create gaps.
ETP Effluent Treatment Plant
Industrial wastewater treated to DoE discharge standards — protecting your licence to operate.
We design and construct ETP systems for textile dyeing, leather tanning, pharmaceutical, and food-processing industries. Our multi-stage biological and chemical treatment processes consistently achieve DoE-compliant effluent parameters, protecting waterways and your operating licence.
Applications
Textile & DyeingLeather ProcessingPharmaceuticalFood & Beverage
STP Sewage Treatment Plant
Domestic and commercial wastewater management meeting BNBC mandatory requirements.
Under Bangladesh National Building Code, commercial buildings above defined thresholds must install sewage treatment systems. We design compact, fully automated STP installations for apartment complexes, hospitals, hotels, and industrial campuses — ensuring BNBC compliance and preventing untreated discharge.
Applications
Residential ComplexesHotels & HospitalityHospitalsIndustrial Campuses
WTP Water Treatment Plant
Clean, safe process and drinking water from surface and groundwater sources.
Our water treatment plants deliver potable and process-grade water from river, pond, and bore-well sources. Filtration, coagulation, disinfection, and softening stages are configured to your specific inlet water quality and end-use requirements — from municipal supply to precision manufacturing.
Applications
Municipal Water SupplyProcess WaterDrinking WaterBoiler Feed
RO Reverse Osmosis Systems
High-purity water for manufacturing, pharmaceutical, and commercial applications.
Membrane-based RO systems remove dissolved salts, heavy metals, and micro-contaminants to produce ultra-pure water. We size and engineer RO installations from laboratory-scale to multi-MLD industrial plants, with pre-treatment, CIP systems, and remote monitoring.
Applications
Pharmaceutical GMPElectronics ManufacturingBeverage ProductionDialysis Water
MLD Million Litre / Day Plants
High-capacity municipal and industrial water infrastructure at scale.
For large-scale municipal water supply, industrial parks, and WASA-affiliated projects, we engineer MLD-rated plants capable of treating millions of litres daily. Our design methodology accounts for peak demand, redundancy, and future capacity expansion without plant shutdown.
Applications
WASA SchemesIndustrial EstatesExport Processing ZonesCity Corporations
ZLD Zero Liquid Discharge
Eliminate all wastewater discharge — the standard for the most demanding export buyers.
Zero Liquid Discharge systems recover and recycle virtually all process water, eliminating effluent discharge entirely. As EU and US buyers impose stricter sustainability criteria, ZLD is increasingly mandatory for export-dependent factories. We engineer ZLD systems with evaporation, crystallisation, and membrane concentration stages tailored to your effluent composition.
