CHFour Energy Solutions designs and builds custom water treatment plants ETP, STP, RO, DM, WWTP, and packaged systems for industries and commercial facilities across Pune and India.
Supplier, Advisor, and Partner
A Water Treatment Plant (WTP) is a facility designed to remove physical, chemical, and biological contaminants from water making it safe for industrial use, discharge, or consumption.
Every source of industrial effluent, building sewage, or groundwater demands a different plant design. At CH Four Energy Solutions, we assess your contamination profile, output needs, and regulatory obligations, then engineer a solution that fits. All plants are built to CPCB and state pollution board norms.
Untreated water damages equipment, harms the environment, and puts businesses at risk of CPCB action. Here’s what a proper water treatment plant protects you from:
Most water treatment plants follow a structured multi-stage process, with each stage targeting a specific category of contaminants.
Bar screens and grit chambers remove large debris — plastics, rags, and sand — before entering main treatment stages.
Wastewater slows in clarifiers; heavier solids settle as sludge and floating grease is skimmed off. Removes 50–60% of suspended solids.
Aerobic bacteria break down dissolved organics in aeration tanks. MBBR, SBR, or extended aeration applied based on design.
Final polishing via sand filtration, UV, or chlorination removes residual particles, nutrients, and pathogens before discharge or reuse.
Our solutions have been deployed across a wide range of industries from small commercial buildings to large-scale industrial facilities.
Businesses who’ve worked with us say the same thing we show up with real solutions, not brochures.
Design, manufacturing, installation, commissioning, and O&M one point of accountability.
Every plant is sized based on your actual flow rates, contamination levels, and footprint.
Familiar with CPCB, MaHa PCB, and local norms. We support you through documentation too.
Minimal sludge, maximum water recovery, and low energy consumption not just audit-ready plants.
Headquartered in Kharadi, Pune with the capability to execute projects anywhere in India.
Tell us your plant type, industry, and capacity — we’ll respond with a practical, no-obligation recommendation.
An ETP handles industrial wastewater containing chemicals, heavy metals, and dyes. An STP handles domestic wastewater from toilets, sinks, and drains. The treatment chemistry differs significantly using the wrong plant leads to compliance failures and system damage.
Yes. Under Maharashtra's building regulations and PMRDA/PCMC guidelines, residential societies above certain thresholds must install and operate an STP. The Maharashtra Pollution Control Board actively monitors compliance, and non-compliant societies can face notices and fines.
Capacity depends on your daily water generation. For residential projects it's based on occupancy and per-capita norms; for industries, on production volumes and process water type. Our team conducts a site assessment before recommending any capacity.
A compact packaged STP can be installed in 4–8 weeks. Larger ETP or WWTP projects may take 3–6 months, accounting for civil work, fabrication, and commissioning. We provide a project schedule before work begins and we stick to it.
Yes, and we strongly recommend it. CHFour offers O&M contracts with trained on-site operators, monthly compliance reporting, and emergency support. Many clients who came to us for installation stayed on for O&M because it removes the operational headache entirely.
A packaged wastewater treatment system is a factory-built, pre-fabricated unit that arrives ready to install with minimal civil work required. It's ideal for sites with limited space, tight timelines, or temporary setups. CHFour offers packaged systems in HDPE, FRP, and MS construction.
ZLD is a treatment approach where 100% of wastewater is treated and recycled, nothing is discharged. It's mandatory for several sectors including textiles, dye intermediates, and distilleries per CPCB directives. CHFour designs ZLD-compatible ETP systems with MEE and ATFD technologies.
Whether you’re at the planning stage or upgrading an existing system, CHFour’s team is ready to help.
