EBN Notional Field Development Plan a delicate subject. • Discharge rates are low in the upper parts of streams located in the south of Noord-Brabant. The following areas in Noord-Brabant are more suitable: • Areas close to the Meuse River (northern border of the Province of North Brabant.) • Those streams with high discharges (eg. De Aa, De Dommel, Esschestroom, de Mark-Vliet) • Canals such as the Zuid-Willemsvaart en Wilhelminakanaal • Those streams with continuous discharge of sewage water treatment installations Withdrawals from the De Dommelstream, the Zuid-Willemsvaart and Wilhelminakanaal canals can require a permit. As a result of strict enforcement regulations, the quality of the surface water is rather good. For example, the effluent of waste water treatment plants in most cases has a low concentration of phosphate (P) and Nitrogen (N), because additional treatment steps are taken to prevent algae bloom and other ecological purposes. Surface waters could be a source water if: • The streams have sufficient capacity and low ecological value. However, many surface waters are considered ‘no-go’ areas. • A permit for withdrawal of surface water is not a year-long guarantee. During droughts water boards are allowed to enforce a zero intake of surface water. Quality of the surface water is rather good, but not free of pathogens etc. This is due to discharge from waste water treatment plants. Detailed information is not yet available. The quality will be at least as good as the effluent of the WWTP. The costs for surface water are determined by permit fees. 4.3.2 Surface Water Withdrawal Restrictions During the summer of 2011, several water boards placed water withdrawal restrictions due to drought conditions: · On 20 May, the Aa and Maas Water Board announced a ban on intake from surface water for the entire Raam district. · On 24 May, the De Dommel Water Board announced a ban on intake from surface water for almost all rivers and streams. Exceptions were granted for the Zandleij (with discharge from sewage water treatment, upper steam of De Dommel and Wilhelminakalnaal · On 19 May, the Brabantse Delta Water Board announced a ban on intake from the following areas: o Bijloop, de Oude Bijloop, de Turfvaart (nr 9) o de Kibbelvaart, Lokkervaart, Bosloop (nr 11) © 2011 Halliburton All Rights Reserved 150
EBN Notional Field Development Plan o de Zoom and de Bleekloop (nr 15) · On 9 June, the ban was extended to the area de WouwseGronden (nr 13) Prior to making a long-term investment into the infrastructure required to use surface water as a water source for the development of shale gas, the potential limitations on reliable water withdrawals warrants further investigation. Figure 4-13. Area of the De Dommel Water Board, including the location of WWTP facilities: 1) Boxtel WWTP, 5) Tilburg WWTP, 6) Eindhoven WWTP, 7) Hapert WWTP, 9) Biest-Houtakker WWTP, 10) Haaren WWTP, 11) Sint-Oedenrode WWTP The capacities of each of these facilities are shown in Table 4-3. 4.3.3 Wastewater Treatment Plant Effluent Water Boards are also responsible for management and operation of Waste Water Treatment Plants (WWTP).
