Water & Sew­er­age

Although Fin­land does not have water short­age like South­ern Europe, our water con­sump­tion has eco­log­i­cal sig­nif­i­cance too. Sav­ing water and plan­ning sew­er­age helps water­ways stay vital and, con­se­quent­ly, improves the nature’s state on a broad­er scale.

Water and waste­water net­work con­nec­tions make it sig­nif­i­cant­ly eas­i­er to orga­nize events out­doors. Water is need­ed in dif­fer­ent phas­es of event food sup­ply, in san­i­ta­tion and in wash­ing up. If the event is not con­nect­ed to a water sup­ply net­work, water must be brought to the venue in tanks or in oth­er hygien­ic con­tain­ers. If sew­er­age can­not be redi­rect­ed to a waste­water sew­er by direct pipeline, it must be pos­si­ble to pump the waste­water into a tem­po­rary tank. The water in the tank must be deliv­ered to a waste­water treat­ment plant. Arrange tank emp­ty­ing with Oulu Water­works: see con­tact infor­ma­tion on Oulu Water­works web­site.

Portable toi­lets famil­iar from fes­ti­vals and com­post­ing toi­lets gain­ing pop­u­lar­i­ty in event use con­sume less water than water toi­lets, but hand­wash­ing facil­i­ties must be arranged for all toi­let types.

Do this


Orga­nize a water point, and advice vis­i­tors to bring their own fil­l­able water bot­tles.

Super­vise that no waste­water or chem­i­cals end up in the soil and, there­by, to the envi­ron­ment and the water­ways. Be espe­cial­ly care­ful if your event is orga­nized close to water.

Do not waste water with a run­ning tap or run water with­out a rea­son.


Do not serve or sell any bot­tled water.

Use clean­ing meth­ods or equip­ment that save water and envi­ron­men­tal­ly friend­ly deter­gents.

Ensure that the taps for fill­ing water bot­tles and hand­wash­ing do not leak.

Next Lev­el

Inform staff and audi­ence about mod­er­ate water con­sump­tion.

Use taps that are hands-free or have low water pres­sure.

Do not waste water for enter­tain­ment pur­pos­es such as foun­tains or tubs.
