OTTIMA has to be installed on waste water pipes and allows the outflow to reach the municipal sewage network avoiding water backflows.
It is highly recommended in cases of:
- Fields which are under the water level
- Areas closest to rivers, lakes, sean
- When the sewage is linked to rainwater pipes (dangerous in case of heavy rain)
- If a sewage network overload has already occurred
- If an extension of the sewage network (with consequent overload) is probable
- When the municipal sewage network includes pumping stations.
