The development shall be carried out in accordance with the approved details.

Reason: To protect and prevent the pollution of controlled waters from potential pollutants associated with current and previous land uses in line with National Planning Policy Framework (NPPF), paragraphs 170, 178, 179 and Environment Agency Groundwater Protection Position Statements which can be found here: https://www.gov.uk/government/publications/groundwater-protection-position-statements

6) No development shall commence until a detailed surface water drainage scheme, to manage surface water run off from the development for up to and including the 1 in 100 year event (+40%CC), and a maintenance and management plan for the scheme has been submitted to and approved in writing by the Local Planning Authority. The discharge rate from the development will be limited to the equivalent 1 in 1 year rate, or an appropriate rate as agreed by the Bedford Group of Internal Drainage Boards. The final detailed design shall be based on the agreed drainage Strategy (to be supplied) and DEFRAs Non-statutory technical standards for sustainable drainage systems (March, 2018), and shall be implemented and maintained as approved. Maintenance will ensure the system functions as designed for the lifetime of the development. Any variation to the connections and controls indicated on the approved drawing which may be necessary at the time of construction would require the resubmission of those details to the Local Planning Authority for approval.
Reason: The details are required before commencement of development to ensure the approved system will function to a satisfactory minimum standard of operation and maintenance and prevent the increased risk of flooding both on and off site, in accordance with para 163 and 165 of the NPPF and its supporting technical guidance.

7) No building shall be occupied until the developer has formally submitted in writing to the Local Planning Authority a finalised 'Maintenance and Management Plan' for the entire surface water drainage system, inclusive of any adoption arrangements and/or private ownership or responsibilities, and that the approved surface water drainage scheme has been correctly and fully installed as per the final approved details.
Reason: To ensure that the implementation and long term operation of a sustainable drainage system (SuDS) is in line with what has been approved, in accordance with Written Statement HCWS161.
