Reuse your wastewater for agricultural irrigation with the fully equipped REUSE manholes

REUSE manholes are compatible with the latest European requirements for agricultural irrigation. These compact units, suitable for installation at the end of the wastewater treatment plant, contain a UV sterilizer specially designed for REUSE quality classes A to D. Thanks to the UV dose delivered, the requirements on the E.coli parameters are guaranteed.

Here are some of the advantages of REUSE manholes :

    • Compact waterproofing structure that can be installed completely underground, partially underground or unburied.
    • Automatic lamp cleaning
    • Upstream and downstream sampling
    • 5 year warranty.

REUSE Reactor UV range

REUSE Reactor range includes 4 sterilizers: S, M, L and XL. For each reactor, the maximum throughput was calculated for each quality class using highly constrained water, namely:

  • TSS = 35 mg/L
  • Transmittance = 50%
  • E.coli concentration: 100 000 UFC/100ml

Of course, if your wastewater leaving the WWTP is of better quality, the same reactor will be able to handle more flow, or you can choose the lower model.

Where to establish the REUSE reactors?

REUSE reactors should be installed at the outlet of the treatment plant, after the tertiary treatment, in order to ensure that the water to be treated meets the treatment requirements imposed on the treatment plant for the TSS, BOD5 and COD parameters.

Why choose this equipment?

This range of reactors has been specially designed for the reutilization of water at the plant outlet. This is why these devices have been conceived with following applications:

  • Automatic online cleaning system to reduce the formation of organic and inorganic deposits on quartz sleeves.
  • Upstream and downstream sampling valves to facilitate sampling during regulatory controls
  • Teflon UV sensor: to continuously monitor the UVC radiation of the sterilizer
  • Chemical cleaning quilting: to facilitate maintenance and increase radiation performance
  • Interface with detailed view:
    • UVC radiation in %,
    • System time counter,
    • System boot counter,
    • System states
  • Various voltage-free contacts to complete the supervision
    • General defect
    • Pre-alarm / alarm: Lamp efficiency decrease warning (i.e. UV intensity) / Lamp efficiency limit reached,
    • Lamp failure
    • An additional free ON / OFF contact

Hydraulic thread too low? Go for REUSE H manholes!

In small wastewater treatment plants, the discharge pipe to the natural environment is often buried. When completely buried, REUSE reactors have a limited connection distance of -190 mm from the center of the pipe. REUSE H (high / lifted) range of reactors makes it possible to dispense with the installation of an intermediate pumping system. By connecting at the right depth, the gravity flow at the plant outlet is maintained!

Range of REUSE raised manhole

To avoid a rejection in a sensitive area and/or to respond to a lack of water.

Wastewater reutilization at the end of the wastewater treatment plant for :

    • Direct REUSE: Irrigation, micro-irrigation, watering,
    • Indirect REUSE: groundwater recharge
    • Agricultural use:
      • Field crops
      • Vegetable farming
      • Prairies
      • Orchards
      • Vineyard
    • Urban use:
      • Golf
      • Green spaces
      • Race track
    • Wetlands maintenance
    • Bathing area protection
    • Washing water for industrial processes
  • Horizontal or vertical installation
  • Automatic lamp cleaning online and without disassembly
  • Upstream and downstream sampling
  • Upstream and downstream purges
  • Stitching for chemical cleaning (CIP)
  • LCD interface with UV intensity display,
  • Several dry contacts to complete the supervision
  • Non-chemical treatment: no harmful chemicals need to be added.
  • Easy to install and to clean: automated cleaning of quartz sleeves to guarantee the efficiency of the equipment
  • Economical and energy efficient:low power requirements
  • Acts on a large variety of pathogens, including those resistant to chlorination (certain protozoa such as Cryptosporidium and Giardia).
  • Recognized by regulatory agencies,including the United States Environmental Protection Agency (USEPA).
  • Effective – Kills 99.99% of microorganisms
  • Ecological: UV does not produce any disinfection by-products that could pollute the environment or limit the reuse of water (as in the case of chlorine or ozone)
  • Reliable: works day and night, 24 hours a day, 7 days a week,
  • Safe for users: no handling of chemicals.
  • Compact and fast treatment: the bacteriological abatement is performed in the reactor. Water flows through the system without the need for a holding tank or reaction time.
  • Continuous controlof disinfection efficiency with remote management to meet operational needs.


On-site delivery by truck. The discharge is the responsibility of the customer.


  • 8 weeks.

Once the order has been placed, the above-mentioned period runs (excluding weeks 31 to 34 and 51 to 52) from the date of receipt of payment and validation of the project plan (including all the options requested in the case of special requests). As soon as the equipment is ready, it will be shipped to you. A road transport requires approximately one week to set up, it can take up to 3 weeks for a container depending on the destination.

    • 2 years for all components except the UV lamp and the quartz sleeve (consumable).

Please refer to the supplier’s specific terms and conditions and user manual for more information.


Defects and damage caused by natural wear and tear, external accidents, wrong assembly, improper maintenance, irregular use, inadequate storage, non-respect of the expiration date, intervention by a third party, or modification of the product not provided for or specified by the seller, are excluded from the warranty.

Please refer to the supplier’s specific terms and conditions for more information.

All the equipment in the REUSE range is equipped with upstream and downstream sampling ports fitted with flammable valves. Bacterial analysis should be done within 4 hours of sampling, on an average 24-hour sample kept in a cool place. The tests must be accompanied by a UV transmittance measurement at 254 nm as well as a TSS measurement.

REUSE manholes are delivered ready to be connected. They can be processed in 3 ways:

    • Completely buried (min. 100 mm overhang – max. -190 mm hydraudic wire)
    • Partially buried (working height 1,10 m – hydraudic wire +860 mm)
    • Unburied (hydraudic wire +1280 mm)

Simply connect the hydraulic inlet and outlet to the flange collars, and connect the electrical cabinet to the mains (220V, 50/60 Hz)

Different ways to install REUSE manholes
UV lamp maintenanceThe lamps are to be removed from the top of the reactor. Before any intervention, remember that :

  1. UV lamps must be recycled according to the regulations of your country. Do not throw them in the regular or industrial waste, as they contain mercury particles.
  2. When replacing a UV lamp, do not put your fingers on the glass. Cleaning the lamps with alcohol will remove any traces.
  3. The light generated by a UV lamp must be carefully protected from direct or indirect view.

When replacing the UVC lamp, be careful not to put your fingers on the glass. Cleaning the lamps with alcohol will remove any finger marks.

When should replacement of wearing parts be considered?

It is recommended to change the UV lamps after 13,000 hours of operation, to maintain the guarantee of a sufficient level of irradiation. This replacement can be done at the same time as the Quartz UV sleeves (if they are damaged). When the sleeves are properly maintained, experience shows that a replacement every two lamps is sufficient (here every 26000 hours / 3 years for example)

How to recycle UV lamps?

That’s easy! Put the old UV lamp in the new lamp package and, for those using original Bio UV reactors, write “recycling” and then ship your used lamps to an approved recycling facility.
