10. Implementing the construction of waste water treatment plants simultaneously with
the construction of water supply systems in the villages. The sewage treatment stations will
clean increased volumes of effluents.
11. Identification and liquidation of illegal effluent discharges in the Oder catchment
area, through periodical controls.
12. The further promotion of inexpensive natural sewage treatment systems (root, reedbed,
and willow treatment systems, biological ponds, etc.) in small settlements.
13. The construction of river treatment stations on smaller, heavily polluted rivers.
14. Stringent control over waste management and waste disposal sites.
15. The construction of pre-reservoirs before large dam reservoirs.
16. The acceleration of activities related to the protection of the atmosphere: the reduction
of sulphur emissions through enrichment of coal before burning, the introduction of
less environmentally harmful burning technologies, the reduction of dust and gaseous substance
emissions.
17. The reduction of the emission of nitrogen, heavy metals and other harmful chemical
elements and compounds which are transported into the soil through the atmosphere, or
exercise a direct adverse impact on the health of vegetation and wildlife.
18. Propagation of the further development of bio-gas plants in order to utilise the liquid
manure.
Agricultural management and horticulture
The following should be carried out:
1. The partial resignation from agricultural activities in the Oder valley and a shift from
intensive agricultural production to the extensive one, together with a simultaneous extension
of pastures and mown meadows, over the areas occupied by arable land.
2. Limitation of the use of chemical pesticides and fertilizers.
3. Restriction of grazing in the areas adjacent to the river which will limit the uncontrolled
damage to trees and shrubs done by cattle.
4. Resignation from the use of herbicides which damage vegetation, as well as from sowing
seeds of selected, highly efficient mixtures of grasses.
Drainage
The approach to drainage activities in the Oder valley and its entire catchment area must be
