At CEEPL, we specialize in end-to-end design and engineering services for water & wastewater infrastructure — including Sewage Treatment Plants (STPs), Water Treatment Plants (WTPs), and Effluent Treatment Plants (ETPs). Our designs integrate client needs, site constraints, sustainability, and operations efficiency so that both capital and operating costs are optimized.
Our scope of design & engineering covers everything from conceptualization to ready-for-construction documentation. Some of the key deliverables include:
Detailed process flow diagrams (PFDs), selection of treatment technologies, process sizing, flow balancing, treatment efficiency targets.
Hydraulic flow diagrams, hydraulic profile calculations, pump sizing, intake/outfall design, pipe network hydraulics.
Layouts combining the civil footprint, mechanical structures, piping, access roads, utilities.
Detailed structural drawings, foundations, tanks, platforms, structural integrity under load and seismic conditions.
Piping & instrumentation diagrams (P&IDs), valve & piping schedules, mechanical equipment selection, schedules & specifications.
Load analyses, transformer & capacitor sizing, switchgear & single line diagrams, cable schedules and routing, lightning protection, earthing.
Design of instrumentation layout, PLC/SCADA control philosophy, sensor specification, control panels.
After construction: updated drawings, plant piping isometrics, record of any changes made.
We provide detailed design and engineering for a wide range of water/wastewater/effluent treatment facilities, such as:
Plant Type | Technologies / Features |
WTP | Rapid Sand Filtration, Multi-Media Filtration, Coagulation-Flocculation, Intake Wells, Gravity Flow, Clarifiers, etc. |
STP | Extended Aeration, Sequencing Batch Reactor (SBR), Moving Bed Bio-Reactor (MBBR), Membrane Bioreactor (MBR), etc. |
ETP / Industrial Effluent | Primary Treatment, Tertiary Treatment, Upflow Anaerobic Sludge Blanket (UASB), Zero Liquid Discharge (ZLD) via RO + evaporator units, etc. |
Here are some of our standout STP / WTP / ETP design & engineering projects, illustrating the breadth and depth of our expertise:
A large-scale WTP project involving not only the core treatment works but also a substantial 150 km raising main. The design addressed intake works, hydraulics, treatment process, civil structures, and distribution for long-distance conveyance.
Two major STP modules designed together, employing SBR (Sequencing Batch Reactor) + TTU technologies. Layouts optimized for modular scalability; emphasis on energy efficiency, sludge handling, and ease of operations.
Urban water supply projects where design engineering covered raw water intake, filtration systems, treatment, plumbing & pipelines, pumping infrastructures, with future expansion in mind.
Municipal sewage treatment plant designed under ASP / aerated sludge process, incorporating civil, mechanical, electrical, instrumentation design for effective treatment with lower operational costs.
Effluent treatment plants for industrial clusters. Designs included treatment module selection, sludge management, compliance with industrial effluent norms, and in some cases provisions or options for Zero Liquid Discharge (ZLD).
A turnkey environmental infrastructure project where CEEPL delivered not just design and engineering, but also detailed planning for long-term operation & maintenance, ensuring sustainability, regulatory compliance and continuous performance.
