Information on increased water storage:
Measures impact on groundwater is positive, there are enhanced possibility of infiltration at the retention pond .
The reason of applying a closed culvert (among other aspects) across the settlement was the protection of groundwater, because an open watercourse would drain the groundwater at low water periods.
Information on runoff reduction:
Runoff is attenuated by the detention pond upstream the settlement. The flow inside the settlement is controlled by the capacity increase of the crossing culvert.
Information on Peak flow rate reduction:
Peak flow is reduced to the capacity of the detention pond, while other part of the catchment no runoff attenuation developments were made the emphasis was given to the storage areas
Information on Maintenance baseflow:
Information on Soil moisture:
Detention ponds and storage areas will increase infiltration, but only very local effect
Information on Water quality overall improvements:
The detention pond above the settlement will serve as a reserve for dilution when water quality problems arise due to low water quantities in the stream. (The effluent of the town†™s treatment plant discharges into the stream)
