13 Jul How are direct discharge sumps treated?
Initially the sump needs to be charged in the same manner as a pond. The initial charge is based on the sump capacity.
Thereafter the daily replenishment is based on the table above in most circumstances and also how much land effluent is spread on per year and the frequency that the same area has effluent applied.
This may result in an adjustment to the daily rate to ensure that the soil receiving the treated effluent can utilise the nutrients to the best advantage for the pasture.
