Stainless Steel Applications – Construction, Infrastructure & Building
Singapore has always focused on increasing our nation’s availability of fresh water due to our dependency of our neighbouring countries for it. The push for self-sustainability came in form of one the largest and most ambitious reclamation project in Singapore known as the Deep Tunnel Sewerage System (DTSS). A used water superhighway for the future, DTSS is a cost-efficient and sustainable solution conceived by PUB, Singapore’s National Water Agency, to meet the long-term needs of Singapore for used water collection, treatment, reclamation, and disposal.
Recently, HH Stainless had partnered with our mills for the supply of high-corrosion resistant super austenitic alloys that are far beyond what the traditional stainless steels are able to withstand for a portion of the 2nd phase of the DTSS project. These are extremely corrosion-resistant materials that are able to withstand the high concentration of chemicals (chlorides), high temperatures, and low pH to achieve longer service life.
Deep Tunnel Sewerage System
Singapore’s Deep Tunnel Sewerage System (DTSS) is a sustainable solution conceived by PUB in the late 1990s to meet Singapore’s long-term needs for used water collection, treatment, reclamation, and disposal.
DTSS uses deep tunnel sewers to convey used water by gravity to centralized water reclamation plants (WRPs) located at the coastal areas. The treated used water is further purified into ultra-clean, high-grade reclaimed water called NEWater or discharged to the sea through outfalls.
DTSS is a key part of our long-term used water system which comprises a network of link sewers leading to two major tunnels (Phase 1 & 2) crisscrossing Singapore with three large WRPs at the northern (Kranji), eastern (Changi), and western (Tuas) ends of Singapore, as well as outfall pipes.
Closing Thoughts
As one of Singapore’s mega projects, our team was honoured to have played our part in Singapore’s push towards a more self-sustainable and greener future. As much as it was a challenging project for our team, we had managed to overcome issues of sourcing, supply chain and project management through the team’s resilience and unity, two of the core pillars that HH Group is built upon. But that being said, none of this could be done without our mill’s support which we have been working with them for the past few decades in a shift towards being a valued partner of high-performance materials.
We are always looking actively for partnerships with the right clients that have the same mindset as us in looking forward to a more sustainable future, hence our focus on stainless steel that is almost fully recyclable upon the end of its life cycle.
