BT1471 SuDS In Schools

Tender description

The Council in its role as a Lead Local Flood Authority is responsible for managing flood risk locally. In the 2015 Local Flood Risk Management Strategy the Council set the following aim: “To enable the management and communication of the risks and consequences of flooding arising from rivers, surface water runoff and groundwater in the borough of Luton”. The objectives to achieve this include: “increasing awareness of flood risk in Luton” and “achieving wider environmental benefits”. The Council is a lead partner in Resilient and Adaptive Communities (RAC) project with the ambition to reduce flood risk and become resilient to climate change, whilst delivering integrated social, economic and environmental benefits. The SuDS in Schools project will support part of a delivery of a pilot scheme under the RAC strategy. To achieve these ambitions and support the implementation of pilot projects the Council, in partnership with Department for Education and the Environment Agency, is seeking consultancy support to identify, assess and mitigate surface water flood risk at or around three schools in the borough. Specifically, consultancy support is needed to provide the information/evidence base required by Section 2 (‘Opportunity description’) of the Thames Water SWMP application form (See appendix A for the application form – please note this is subject to updates).The outcomes of the tender will be: 1. Concept designs of the SuDS solution to reduce surface water inflows to the TW sewer network with integrated educational features 2. Calculations detailing the area (Ha) disconnected and/or attenuated from the Thames Water network 3. A short technical note detailing the methodology, data, any assumptions and maintenance requirements. Section1: Background & Context Luton Borough Council is committed to mitigating flood risk to people, properties and infrastructure within the borough. A Surface Water Management Plan (endorsed by the Council’s Executive Committee in 2011) and Local Flood Risk Management Strategy have identified objectives to manage flooding and communicate risks locally. More recently, the Resilient and Adaptive Communities strategy has been endorsed in 2021 by the CEO and leader of the Council as it aligns to the Luton 2040 vision, and supports the strategic priorities of the Council (See appendix B) as well as the Thames Flood Risk Management Plan. Thames Water is anticipated to invite applications for funding from their Surface Water Management Programme (SWMP) in mid-February 2022 which is part of their performance commitment as part of water industry’s Asset Management Plan 7 (AMP7, 2020-2025).?Successful applications for Thames Water SWMP funding must use SuDS and disconnect or attenuate surface water flows from Thames Water’s network. The Council would like to apply to this invitation for funding to support the SuDS in Schools project. Section 2: Service Requirement The selected consultant must provide: 1st Phase Initial screening (within 3 weeks of contact award): a mostly desk based review with 1 site visit for up to 6 schools in order to: a) Prove connection into the Thames Water network. b) Early consideration of the scope /feasibility of incorporating SuDS measures at the school. c) Establish whether any refurbishment/extension works are planned at the school, which may provide an opportunity for SuDS rather than simply connecting to the existing piped system that outfalls to Thames Water network. 2nd Phase (3 schools selected following screening, November 2021 to February 2022): 1. Confirm the existing drainage arrangements at each school and identify the point of connection into the Thames Water network 2. Quantify the impermeable area within each school draining to the Thames Water network 3. In consultation with stakeholders (1x 2hr meeting), identify options for each school (Sustainable Drainage Systems in compliance with measures and design principles of CIRIA753) to disconnect or attenuate flows arising from the impermeable area from the Thames Water network. 4. For each option provide calculations (based upon industry-standard methods) for the area (Ha) and volume of surface water disconnected and/or attenuated from the Thames Water network. 5. In consultation with stakeholders (1x 2hr meeting), agree the preferred option to be taken forward to concept design for each school. 6. Prepare concept designs (3 in total) in accordance with Thames Water SWMP application form (Appendix A - please note this is subject to updates) that includes: Keywords: SuDS, Schools, Flood
