Overall AWS considers that the identified sites have a good potential to deliver the required housing numbers during the Plan period. Given that we assess the prospect of delivering 894 homes a year by 2029/30 as Amber due principally to supply side constraints including construction sector capacity, the uplift in housing numbers would need to deliver in the second, third and final quarters of the Plan period. In locations with constrained WRC capacity, such as the Deepings, AWS will submit investment Plans to regulators in line with the water sectors mandated five-year investment planning cycle. That investment, if approved, would be undertaken in the 2030s and so we recommend that allocations are phased in line with the capacity identified in the Plan’s WCS.

AWS supports focused growth at scale in principle as opposed to spreading growth around as focused growth is both investment efficient and has carbon economies of scale. The Garden Village together with other planned growth around Grantham is above our nominal threshold of 2,000 homes/ 5,000 people for the top tier of embedded (capital) carbon efficiency in providing new WRC capacity. The total of circa 5,000 new homes at Grantham after the mid- 2030s which will require additional WRC capacity once existing headroom is used will enable AWS to consider the design options including expanding the Marston WRC in the next business plan to be agreed by Regulators for funding in or about 2029.
SKDC and potential developers of the 110,000m2 of employment uses are advised to contact planningliaison@anglianwater.co.uk at the earliest opportunity for advice on water supply and wastewater options.

With reference to part m. (page 18) AWS welcomes the requirement to demonstrate ‘wastewater treatment works’ (WRC) capacity. For the residential elements of the Garden Village, if it is developed later in the Plan period then the Policy will need a requirement that developers must demonstrate in liaison with AWS and confirmed by the Environment Agency that additional WRC capacity has been provided. If that capacity has not been provided a condition may be required that homes which would result in exceedance of permitted flow limits at the Marston WRC cannot be occupied until that capacity is demonstrably available and would not increase the risk of harm to the water environment.

AWS comments for the Garden Village equally apply to: Rectory Farm (Phase 2), including part j. of the policy regarding WRC capacity.
