Request for Proposal (RFP 2101 and 2102)


PUB will be launching a grant call on 13 Sep 2021 under the Research Innovation and Enterprise 2025 Competitive Funding for Water Research (CWR) programme to invite Institutes of Higher Learning, research institutions and industries to submit proposals.

There are two Request-For-Proposals (RFPs):
1.   RFP 2101: Recovery Chemicals & Minerals from the Water Loop
​​2. ​  RFP 2102: Projecting the Impacts of Climate Change on Singapore’s Water System

RFP 2101

Recovering Chemicals & Minerals from the Water Loop

As a small city state, Singapore has always been aware of the need to balance economic development and environmental sustainability. Reducing waste and adopting a circular economy approach will benefit the environment and create economic opportunities. Circular economy also provides opportunity to increase Singapore’s resilience against disruptions to global supply chains.

This RFP hence solicits technologies and solutions that can recover the following two categories of useful resources:
i)    Chemicals needed in water and used water treatment processes from local waste streams (including, but not limited to, waste streams produced by PUB).
ii)   Rare metals relevant to industries from seawater desalination brine.

More details on the RFP 2101 can be found in the Fact Sheet

RFP 2102

Projecting the Impacts of Climate Change on Singapore’s Water System​

As the effects of climate change become increasingly pronounced around the world, there is need to address the longer-term impacts of climate change on Singapore’s water systems, including the effects on various water sources such as local catchment, seawater and NEWater. This RFP hence aims to study the impact climate change has on the Singapore water system for the next 10, 20 and 40 years, so as to guide the formulation of future adaptation strategies.

The study shall address two focus areas, namely the impact to (i) water quality and (ii) PUB’s infrastructure. Applicants are also free to propose other areas of study, except for areas related to flooding and coastal protection where separate studies are already ongoing.​
