Why Mejec

  • Environmental compliance icon
    Environmental Protection and Compliance
    Every system is engineered to the discharge standard that applies at your site, with disinfection built into the treatment train rather than bolted on afterwards.
  • Contaminant removal icon
    Efficient Contaminant Removal
    Mature biological processes strip organics, suspended solids and ammonia nitrogen from the stream, and hold that performance when load and water quality fluctuate.
  • Low operating cost icon
    Operational Cost-Effectiveness
    Factory prefabrication removes most of the civil works, and optimised processes keep both energy draw and sludge disposal down across the life of the plant.
  • Scalable modular capacity icon
    Adaptability and Scalability
    Choose the process to suit your influent, then add modules in parallel as demand grows — capacity expands without rebuilding what is already running.
  • Water recovery and reuse icon
    Resource Recovery and Reuse
    Treated effluent is clean enough to put back to work for irrigation, flushing and landscape water, instead of being discharged and paid for twice.
  • Automated control and remote monitoring icon
    Automation and Low Maintenance
    PLC control with remote monitoring, fault alarms and unattended operation, so a site stays compliant without a dedicated operator on the payroll.

Frequently Asked Questions

How much land do we need to reserve for the treatment plant?

Far less than a built-in-place plant. Buried Johkasou units need only a small excavation pit and the surface above can be planted, paved or used for parking, so they consume no above-ground building allowance. A 20 m³/d SB unit is a Φ2.2 × 5.3 m cylinder; a 100 m³/d configuration is two Φ2.2 × 11.5 m cylinders. Containerised units occupy a standard shipping container footprint on a level slab.

Can capacity be phased to match the delivery programme?

Yes, and that is usually the cheaper route. Containerised units run 50 to 600 m³/d each and combine up to 10,000 m³/d, so you install what phase one needs and add modules in parallel as later phases complete. The MABR range is designed specifically for linear expansion through parallel container units.

Will residents notice it?

Buried units operate in a sealed underground environment that effectively isolates noise and odour, which is what makes them viable directly beneath courtyards and landscaping. The constant underground temperature also stabilises the biology, so treatment performance holds up better through seasonal swings.

Can the treated water be reused within the development?

Yes. Containerised MBR units produce effluent at BOD₅ 10 mg/L, ammonia-nitrogen 5 mg/L and suspended solids 5 mg/L with faecal coliform below 50 CFU/100 mL, which is suitable for landscape irrigation, water features and general cleaning rather than discharge.

What if the site cannot drain by gravity?

Use the LD-BZ integrated prefabricated pumping station. It buries a complete package — pipework, pumps, control gear, screen and maintenance platform — into a single barrel from Ø1.2 to 6.5 m, handling 480 to 18,960 m³/d at flows of 20 to 790 m³/h.
