CSE – HUDD MoU :

• 3 year partnership aimed at enhancing urban water supply sustainability / security in towns and cities of Odisha part of an overall urban strategy.

• CSE has agreed to work with HUDD to provide technical and programmatic support on water sensitive urban design/ planning and implementation aimed at mainstreaming rainwater harvesting in town and cities across Odisha.

The initiative is aimed at making water sensitive cities integrating urban water cycle, water supply, storm-water and groundwater management with spatial and urban design intervention in select town/cities. JOURNEY SO FAR

CSE – HUDD MoU Signed on WSUDP & RWH dt. 27th May 2020 HUDD Issues Advisory on implementation of WSUDP – Phase I dt. 2nd June 2020 for PAP & FAP at city level within one month before onset of monsoon. CSE submitted ‘ Report RWH Potential of Green Open Spaces / Parks’ dt. 08/06/2020: Detailing Method of RWH in 3 different size Park in 4 cities : Bhubneshwar, Cuttack, Rourkela, Berhampur Rourkela & Berhampur set up City Level Group and prepare PAP CSE & announces Sensitisation cum Capacity Building and Need Assessment workshop with CSE dt. 12 June 2020 Aim: Sensitization cum Capacity Building Need Assessment for Implementation of Water Sensitive Urban Design and Planning (WSUDP) - rainwater harvesting in parks and open spaces in select cities Objectives: - Sensitization of key functionaries with scope and objectives of the advisory on WSUDP - Phase I issued by HUDD dt. 2nd June, 2020

- Provide overview of different methods of rainwater harvesting in parks and open areas (incl. data and information requirements)

- Discuss Preliminary Action Plan prepared by ULBs (if any) • Identify capacity building requirements of urban local bodies in doing • Feasibility study and implementing PAP prepared by ULBs • Feasibility study and executing other method of rainwater harvesting in Parks and Open Areas • Monitoring and Supervision of WSUDP interventions incl. Operation and Maintenance of RWH systems

Water sensitive approach • Protecting local waterbodies (lakes, ponds and wetlands) for supplementary water sources Water demand and supply- Water Conservation • Storm-water management at public places, including open Wastewater Rainfall and green areas / parks in cities reuse and runoff- Rain recycle- Water water pollution red Sensitive harvesting Urban Design • Increasing water-conservation and Planning approaches at various scales (WSUD&P) (buildings/campus).

Flood Localised mitigation - On-site water conservation with Water resource SWM green management infrastructure rainwater harvesting (RWH) is important to reduce water scarcity. Scales?
