Water distribution at public events: how to supply an event safely

Festival, carnival, concert, market, sports event, municipal event or large popular celebration: as soon as an event brings people together, water needs quickly grow — visitors, sanitary facilities, food stands, bars, washing points, organising teams.

Laying a few hoses and taps does not make a reliable supply. A temporary installation must be designed as a genuine small hydraulic network: water inlet, distribution, pressure, flow, connections, protection, drainage and dismantling. That is exactly what Weber Water takes on for events and festivities in Belgium.

At an event, water serves drinking water points, sanitary facilities and toilets, hand-washing, food stands and temporary kitchens, cleaning, bars, technical installations and certain safety infrastructure. Needs vary greatly with size: a small municipal event does not call for the same installation as a festival with thousands of visitors.

It all starts with the water requirement: expected attendance, duration of the event, number of distribution points and sanitary facilities, presence of food stands, organisers' needs, site constraints. The available flow is then compared with the required flow. Correct sizing avoids the classic problems: lack of pressure, insufficient flow, undersized hoses or an overloaded network.

Depending on the site, Weber Water sets up a complete chain: water inlet, filtration and protection, main network, branches, water points. Pipes are laid temporarily on the ground or in a configuration suited to the site, taking into account pedestrian and vehicle traffic to limit the risk of damage.

As soon as water is intended for human consumption or food activities, sanitary requirements become essential. Water used in the food sector must, in most cases, be of drinking quality and comply with the applicable regulations. Drinking water networks must therefore be clearly distinguished from technical networks.

Several distribution points are better than one: drinking water for visitors, sanitary facilities, hand-washing, food stands, technical needs. This organisation spreads the flows and limits disruption across the whole network.

Assuming the network pressure is automatically enough is a common mistake: when several taps run at once, pressure drops. Pipe length, diameter, fittings and height differences between points also play a part. When the available pressure is insufficient, a pressure boosting system can be considered.

At a public event, safety is not only about water quality. Installations must be protected against impacts, crushing, disconnection, leaks, accidental handling, frost depending on the season and backflow. Connections stay accessible for maintenance while being protected from the public.

Dismantling is part of the service: closing and securing the water inlet, purging the pipes if necessary, dismantling the distribution points, checking the equipment, storing the material properly and checking it before the next use. Good preparation allows the equipment to be reused across several events.

Weber Water supports municipalities, organisers, associations and businesses in setting up temporary water networks: drinking water distribution, water points for festivities, supply to sanitary facilities, stands and infrastructure, pumping and pressure boosting, connections, installation and dismantling, checks and repairs. The goal is simple: a reliable, properly sized water supply adapted to the site.
