Notional Field Development Final Report - EBN

EBN Notional Field Development Plan
concentration of Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), N-Total, P-Total
and suspended solids. The concentration of E-Coli per WWTP is unknown and would need to verified,
but probably ranges from 5,000 to 400,000 units per ml.
Effluent from a WWTP with pipelines being used to transport the water could be a possible provider of
source water for shale gas development in the Netherlands. In most cases the location of the WWTP is
not the same as the discharge point and the exact location of all discharge points has not been
determined.
Use of WWT effluent could be limited during the summer as the effluent may be the only re-charge
source of some surface waters. The potential to use the effluent for fracking operations would be
temporarily restricted during drought conditions.
Information about the available capacities of WWTPs in Zone 8C can be found in Table 4-3. Subject to
verification with the various water boards, this water could be used if the required capacity is below
20% of the dry weather discharge requirements.

The cost of water is determined by permit fees and possible price per m3. The prices for WWTP effluent
water would be significantly less than the price of drinking water. It is also important to note that this
effluent water may require additional pre-treatment with biocides prior to being suitable for use in
fracking operations.
