At the end of day two, the loudspeaker announces that the exhibition is closing. In the aisle with tank booths, three exhibitors open their valves together. The nearest floor drain is one of just a few. Water spreads across the aisle carrying the smell of salt and a hint of something fishy. The cleaning contractor, hired on a normal trash schedule, has brought nothing to deal with it.

A car show or an electronics show rarely has to worry about water. An aquaculture show does. This article is about wastewater at an aquaculture trade show, drawing on the cleaning and venue sections of the CEM guides.

Where wastewater comes from

  • Water in demo tanks, usually saltwater or brackish.
  • Water from washing tools, tanks and the floor around booths.
  • Melted ice from sample boxes or displayed seafood.
  • Disinfectant water used on hands, shoes and tools, as the article on biosecurity at the show mentions.
  • Water and liquids that come with the biological samples of hatcheries, probiotic firms and testing labs.
  • Water from catering areas, which the CEM guides treat as a separate food-service item.

Each type needs different handling. Lump them all together as "wastewater" and the organizer will not know what to ask the venue.

Four questions for the venue

The CEM checklist for exhibition hall site visits already includes the relevant items: water and gas lines, including flexible water and compressed air, the location of drains, available electrical power, waste removal and pickup, and fire regulations. From there come four questions for an aquaculture show:

  1. Where are the floor drains and how many are there? On a technical floor plan, drains are marked D and plumbing boxes P. How to read them is in the article on the technical floor plan of a hall.
  2. Can the drainage system accept saltwater, and what about disinfected water? If the venue does not accept it, the water must be held and taken away another way.
  3. Who collects waste and wastewater, and at what charge? The finance guide notes that venues typically charge for trash removal, especially when special equipment or extra staff are needed, and that this should be negotiated clearly in the contract.
  4. Does the venue have an exclusive cleaning or waste service? That falls under the article on venue exclusive services.

For disinfected water, biological samples or saltwater, ask the local regulator too and take specialist advice. Rules differ from place to place.

Who does what

The CEM guides describe cleaning and trash removal as falling in one of three cases: included in the venue's contract, hired and managed by the official service contractor (OSC), or handled by a subcontractor the organizer designates. The organizer reconfirms the cleaning schedule with all parties, especially at peak times. Recycling and the removal of hazardous waste must also be monitored throughout the show. The cleaning schedule must match the security schedule so cleaners can reach the areas they need to. Exhibitors may have specific cleaning requirements for their own booths.

From that, a suggested split for an aquaculture show:

  • The venue: the drainage system, the water supply and general trash collection.
  • The cleaning contractor: floor cleaning, emptying bins on schedule and wiping up spills.
  • The exhibitor: the water in their own tank, drip trays, containers for biological waste, and taking biological waste away as instructed.
  • The organizer: writing the rules, setting the draining schedule, supervising and recording costs.

A plan in three phases

Before the show

Ask exhibitors about water needs right in the registration form: is there a tank, roughly what volume, what kind of water, is it disinfected, are there biological samples. Place water-using booths near drains, as discussed in the article on booths with water tanks. Require drip trays and waterproof liners under tanks, and send the rules in the exhibitor rules.

During the show

Set cleaning times for the peak hours: after lunch and at the end of the day. Distribute a staggered tank-draining schedule so one drain is not overloaded. Place bins with lids at points where there are samples and ice. The person walking the floor checks for wet floors and smell, as the article on the floor manager describes.

At move-out

This phase is often forgotten. Drain tanks slowly so the drain does not overflow, dry the floor before heavy equipment moves, and clear sample containers as instructed. Water-using booths should be the last checked before the hall is handed back.

Smell and organic waste

An aquaculture show can have shrimp shells and heads, ice mixed with water, foam boxes and spoiled feed bags. Organic waste left in a warm hall begins to smell within hours. To reduce it: collect more often than at a normal show, use closed bins, separate organic from dry waste, and ask the venue for a collection point away from visitor routes. The article on a sustainable exhibition adds ways to measure and reduce the volume.

Suppose it goes like this. The organizer sends a staggered draining schedule to seven water booths, each a short interval apart, and has a contractor stand in that aisle at the end of the day. The drain runs the whole time and the floor is dry when security locks the doors. The cost of one extra person on watch is far less than carpet repair and apologies.

Extra charges like this should have a place in the budget contingency for the show from the start.

Need a water and waste plan for an aquaculture show?

If you need a list of questions for the venue, a cleaning roles table or a draining schedule for tank booths, you can send a request through the quote page or book a call with Nguyen Anh Trung. Send the hall plan and the expected list of water booths.

Once water is in the aisle, it is no longer only the tank booth's problem.
