Water Filtration System for Drinking —
Municipal & Community Supply.
We assess source water type, turbidity, TDS, microbial load, and daily demand before specifying a single component. The treatment train we design for your community follows your actual source water conditions — not a fixed product list. We configure each water filtration system for drinking water supply around your source water type, daily demand, and applicable national standard.

Which of these sounds like your community water project?
Three pre-engineered configurations matched to the most common community water sources. Find the description that fits your site — then request the full specification from our engineering team.
Rural community on borehole or well water
Groundwater source — iron, fluoride, or hardness issues
- Well or borehole is the source — not a river or canal
- Water looks clear but tastes metallic, stains surfaces, or causes health concern
- Community of 100 to 5,000 people needing safe drinking water
Remove iron, manganese, or fluoride → Filter fine particles → Kill bacteria and viruses → Store → Distribute
After you submit — an engineer reviews within 24–48 h. No complete water analysis required to start; send available data and we will identify missing tests before final design.
Community on river, lake, or canal
Surface water — turbid or seasonal quality variation
- River, lake, or canal is the source — water turns brown or turbid after rain
- Algae, organic load, or seasonal turbidity spikes cause supply problems
- Treatment must handle high variation in source water quality
Coagulate and settle turbid water → Filter → Kill bacteria and viruses → Store → Distribute
After you submit — an engineer reviews within 24–48 h. No complete water analysis required to start; send available data and we will identify missing tests before final design.
Community water tastes salty or brackish
Inland brackish groundwater — TDS above drinking standard
- Borehole water is salty, bitter, or fails WHO drinking water standard
- Community is inland — no access to fresh surface water
- Standard filtration alone will not fix salinity — desalination is needed
Pre-filter → BWRO desalination to remove salt → Adjust pH and taste → Kill bacteria → Distribute
After you submit — an engineer reviews within 24–48 h. No complete water analysis required to start; send available data and we will identify missing tests before final design.

From source water to safe drinking — the community water filtration system for drinking supply.
The treatment route depends on your source water type. Groundwater requires iron and pathogen control. Surface water adds coagulation and sedimentation. Brackish groundwater adds membrane desalination. Each stage has a defined function and a defined failure mode if omitted.
| Stage | Key Operating Parameter | Engineering Consequence if Undersized / Omitted |
|---|---|---|
| Coagulation (OPT) | Match coagulant dose to source turbidity and pH; jar test before commissioning. | Without coagulation, high-turbidity surface water (50–300 NTU) clogs multimedia filter within days of a rain event — not within months. |
| multi media filter | Turbidity ≤ 1 NTU at outlet; SDI < 5 before carbon and membrane. | Turbidity above 1 NTU entering the UV chamber shields pathogens; UV dose below design is delivered without any alarm. |
| industrial activated carbon water filter | Chlorine below 0.05 mg/L before RO membrane; EBCT minimum 10 min for free chlorine. | Polyamide RO membrane oxidises progressively under chlorine — salt rejection falls within weeks and membrane requires early replacement. |
| RO membrane (OPT — high TDS / salinity source) | 50–75% recovery; reject volume and disposal planned before commissioning. | Where source TDS or ionic content causes taste, scaling, or regulatory exceedance after filtration alone, membrane treatment is evaluated after full ionic analysis. |
| uv disinfection water treatment | Validated dose at design flow; inlet turbidity must be ≤ 1 NTU; no residual protection in distribution — chlorination strategy reviewed separately. | Turbidity shields pathogens from UV; the effective dose reaching each organism drops below the inactivation threshold without triggering any alarm. |
The pre-treatment standard for turbidity control is separate from the membrane pre-treatment standard. A community RO system requires SDI < 5 at the membrane inlet, achieved through multimedia filtration and activated carbon upstream. The UV steriliser requires turbidity below 1 NTU at its inlet to deliver the specified dose — these two requirements must both be met by the pre-treatment train. Where surface water organic load or colour is high, an ozonator for water treatment may be evaluated as pre-treatment oxidation ahead of filtration.
Source water type determines treatment depth
Groundwater routes: iron and manganese removal → multimedia filtration → UV. Surface water adds coagulation and sedimentation before multimedia filtration. Brackish groundwater adds RO after pre-treatment. The right equipment for a clean borehole at 300 mg/L TDS is materially different from a river intake at 200 NTU seasonal turbidity — we size each after confirming your source water data.
Sizing a community system from daily demand
Community water demand typically ranges from 50 to 150 litres per person per day for basic supply. A village of 500 people at 100 L/person/day requires 50 m³/day treated output — equivalent to roughly 2–3 m³/h continuous flow. Storage sized to 8–12 hours of daily demand provides a buffer against source pump failure or peak morning draw, without requiring the treatment plant to match instantaneous peak flow.
UV disinfection can inactivate microorganisms at the treatment station, but provides no residual protection in storage tanks or distribution pipework. Community drinking water systems with storage and pipeline distribution should include residual disinfectant (chlorine or chloramine where permitted), sanitary tank design, screened vents, routine flushing, and periodic E. coli / total coliform monitoring according to the applicable national drinking water standard.
Engineering variables reference.
These variables determine whether the treatment route is filtration-only, filtration with RO, or filtration with BWRO — and which pre-treatment stages are required for your source water type. For small municipalities and rural communities, a water purifier system for drinking must be matched to source water risk, not a fixed product list.
| Parameter | Typical Range | Engineering Consequence | Configuration Approach |
|---|---|---|---|
| Source water type | Groundwater (borehole/well), surface water (river/lake), or brackish groundwater | Single most important routing decision; determines whether coagulation, UF, or BWRO is required upstream of filtration. | Groundwater: filtration + disinfection. Surface water: adds coagulation + sedimentation. Brackish: adds BWRO after pre-filtration. |
| Source water TDS | 500–600 mg/L is a palatability and scaling review range, not a WHO health-based limit | Above 500–600 mg/L, individual ions (sodium, chloride, sulfate, nitrate, fluoride) may affect taste, cause scaling, or exceed local drinking water limits; membrane treatment is evaluated from full ionic analysis. | BWRO reduces TDS to drinking standard; reject volume and disposal confirmed before commissioning — not resolved at installation. |
| Source water turbidity | < 1 NTU groundwater; 10–500 NTU surface water after rain events | Turbidity above 1 NTU at UV inlet shields pathogens from UV dose; effective inactivation falls below design threshold. | Surface water: coagulation + sedimentation + multimedia filter. Groundwater: multimedia filter sufficient for most sources. |
| Activated carbon EBCT | ≥ 10 min for free chlorine; ≥ 15 min for chloramines | Free chlorine above 0.05 mg/L degrades polyamide RO membrane; also affects taste at municipal supply chlorine concentrations. | ACF mandatory ahead of RO; sized from inlet chlorine concentration and daily throughput. |
| UV dose | Validated dose selected from UVT, rated flow, target organisms, lamp aging allowance, and sleeve fouling. 30–40 mJ/cm² is a common screening reference for bacterial control under favourable UVT conditions. | Below design dose, pathogen inactivation falls short; turbid water shields microorganisms from dose without triggering any alarm. UV has no residual protection after treatment; storage and distribution require separate residual disinfection strategy. | UV inlet turbidity must be below 1 NTU; UV lamp replacement at 8,000–12,000 operating hours. |
| Community daily demand | 50–150 L per person per day for basic supply | Undersized system creates supply gaps at peak morning demand; insufficient storage causes unfiltered bypass during maintenance. | Total daily volume sized from population × per-capita consumption; storage sized for 8–12 hours daily output. |
| Backwash water consumption | 3–5% of daily treated output per backwash event | Remote sites with limited reject disposal capacity need backwash volume management built into the design. | 1–2 backwash cycles per day typical; differential pressure trigger more reliable than calendar-based backwash scheduling. |
| Iron and manganese in groundwater | Iron 0.3 mg/L and manganese 0.05 mg/L are common aesthetic / secondary targets; local health-based values and limits may differ — confirm against national drinking water standard | Iron above 0.3 mg/L stains surfaces red; manganese above 0.05 mg/L causes taste complaints and long-term health concern. | Oxidation + contact filtration for iron removal above 0.3 mg/L; confirm analytical results before specifying the oxidation stage. |
| Fluoride in groundwater | < 1.5 mg/L WHO guideline | Fluoride above guideline causes dental and skeletal fluorosis with long-term exposure — a common concern in parts of Sub-Saharan Africa, South Asia, and the Rift Valley. | Activated alumina or BWRO for fluoride removal; activated alumina less energy-intensive for fluoride-only sites. |
| BWRO recovery | 50–75% for brackish community systems | Lower recovery wastes treated water — a constraint at water-scarce remote sites where every litre of reject must be accounted for. | Set by feed TDS, membrane selection, and available reject disposal capacity at the community site. |
| Arsenic / nitrate / microbial indicators | Arsenic, nitrate/nitrite, E. coli, and total coliform must be tested for groundwater used in drinking supply; WHO arsenic guideline 10 µg/L | Clear borehole water can still fail drinking standards due to dissolved contaminants or faecal contamination — appearance is not a safety indicator | Select adsorption, ion exchange, RO, disinfection, or source protection after full laboratory analysis and local regulation review; do not assume contamination-free from appearance alone |
