LST GIS support for small sewer planning and supervision — Groundwater Service (API)

API to calculate groundwater filling and dimensioning levels at high groundwater flows, with the aim of providing support for installations of small sewers.
The ground water calculation is based on the methodology described in the Swedish Agency for Marine and Water Management (HaV)'s guide for the examination of sewers.
The service assesses the level of groundwater at high groundwater conditions (dimensioning reservoir level).

Land-based sewerage systems must always take into account high groundwater levels. The design level shall be chosen in such a way that the requirement of one metre unsaturated zone is met for most of the year.
