The particular challenges faced by places on this peninsula lie in the extreme fluctuations in the amounts of wastewater that occur. During the holiday season, the volume of wastewater to be disposed can increase to as much as seven times the usual amount. The ground-water level is also very high, which means that normal gravity sewers are not feasible. This is a case for pressure drainage systems.
