We offer the option of installing our Izvor biopurifier in existing concrete pits or in pits that you will build. We can adapt the biopurifier to your pits or offer you advice on building new pits. Considering your needs, i.e. the number of users, and the quality of purified water you want, we offer several types of purifiers. We offer two-chamber, three-chamber, four-chamber and multi-chamber pits depending on demand.
