Typical drain cleaning and maintenance

 The Public Utilities Board (PUB) manages Singapore’s water supply and drainage systems, including the maintenance of drainage systems to prevent water ponding and flooding (Public utility Board, 2023b).

PUB conducts regular inspections to detect any clogging or damage to the system and performs structural repairs and maintenance as needed (Public Utility Board, n.d). The Department of Public Cleanliness (DPC) conducts regular drain cleaning (Kiasu Plumber, 2020). Equipment such as special nozzles, combination tankers, and high-pressure jetting equipment is used for this process (Lian Shing, n.d.). This cleaning process helps to remove debris and waste that may be blocking the drain flow. On top of that, collection devices such as float booms and litter traps are also placed strategically along the drains(Kiasu Plumber, 2020).

This proactive approach to maintenance and cleaning helps to prevent water ponding and flooding, while also protecting public health in Singapore.

These opportunities have helped me understand the importance of effective communication, and I am eager to continue developing my skills in this area. My next goal was to improve my writing and critical thinking skills. I am glad to say that I had made significant progress in this area. The summary reade...

Summary Draft 2: SolarNova Programme

According to the Housing Development Board (HDB) (2022) article, "HDB to Bring Solar Energy to Over 8,000 Blocks Through SolarNova Programme," HDB announces its seventh solar leasing tender for the SolarNova Programme. The Singapore Economic Development Board (EDB) is co-directing the programme, which aims to expedite the installation of photovoltaic (PV) systems in Singapore. This initiative is also a crucial element of the HDB Green Towns Programme (GTP), which strives to make HDB towns more sustainable by reducing energy usage with solar panels. With this initiative to promote greater usage of solar panels, carbon emissions can be greatly reduced thus mitigating climate change. Currently, HDB has committed to a solar capacity of 380 megawatt-peak (MWp). With its new tender, HDB announces a target of 540MWp by 2030 for over 1,290 HDB blocks and 99 government sites. Mr Tan (as cited in HDB, 2022), states that this programme, as a vital part of the HDB GTP, aids HDB in achi...
