“…Liquid waste, commonly referred to as wastewater, constitutes the water supply used within the community for various purposes. Any water quality adversely affected by human activities is classified as wastewater [37]- [39]. In terms of its sources, wastewater can be described as a combination of liquid or water-borne waste originating from households, institutions, commercial and industrial establishments, and may also include groundwater, surface water, and stormwater [40]- [47].…”

An estimated 38 million individuals, out of a total population of around 126 million, reside in urban areas of Bangladesh. The surge in urbanization and water consumption has led to a significant rise in waterborne sanitation systems within the country. One cost-effective solution for wastewater treatment is the utilization of septic tanks, which operate as anaerobic reactors, with their efficiency being closely tied to temperature conditions. This research focuses on evaluating the organic removal capabilities of a septic tank located on the Khulna University of Engineering and Technology (KUET) campus. The results show that a septic tank's ability to remove organic matter depends on the temperature, with higher temperatures making the removal process more effective. Additionally, the Total Suspended Solids (TSS) levels were observed within a range of 110-280 mg/L, 200-1030 mg/L, 160-880 mg/L, and 190-220 mg/L for the 1st, 2nd, and 3rd chambers, respectively.The maximum recorded pH values were 7.14, 7.13, and 7.11, while the minimum pH values were 7.06, 7.05, and 7.04, corresponding to the same chambers. Furthermore, the organic removal efficiency concerning dissolved oxygen (DO), nitrate (NO3-N), and pH levels remained within acceptable limits. These results suggest that a simple treatment unit like a septic tank can effectively render previously unacceptable and unhygienic water suitable for safe disposal and potential reuse, ultimately improving the management of septic tank wastewater.

“…Its influence on wastewater quality is direct [45]- [47]. Ensuring effective management is crucial to prevent treatment facility effluent from adversely impacting the quality of the overall water supply [48]- [51], [52]. This, in turn, contributes to the establishment of a more secure and dependable water supply system.…”

The growing demand for water resources in urban areas like Bangladesh is a pressing concern due to population growth. Air conditioning condensate water is being considered as a potential solution. A study at the European University of Bangladesh (EUB) examined the quality of AC condensate water from various systems. Results showed that the water generally met quality standards for drinking and household use in Bangladesh, with average parameters like pH (6.8), turbidity (1.08 NTU), total dissolved solid (TDS) (219 mg/L), iron (0 mg/L), alkalinity (41.67 mg/L), arsenic (0 mg/L), COD (3.67 mg/L), BOD (1.33 mg/L), chloride (30.77 mg/L), and more. AC units at EUB (1 ton, 2 tons, 4 tons) produced monthly volumes of 96, 177, and 354 L, highlighting the potential of AC condensate water. This emphasizes the need for local decision-makers to establish guidelines for its effective use in combating urban water scarcity.

“…Where brick manufacturing has rapidly expanded, ensuring a reliable water supply and efficient sanitation system has become increasingly vital [58][59][60]. As mentioned earlier, the elevated chloride content in water sources not only endangers the environment and construction materials but also affects the overall quality of the water supply [57,60,61].…”

The brick manufacturing sector in Bangladesh is experiencing rapid growth, leading to notable environmental and health concerns. The primary objective of this research is to examine the Savar Upazila, a region of significant economic significance owing to its favorable brick manufacturing conditions and proximity to Dhaka city. Brick kilns, among other sources, constitute significant contributors to air pollution. The study utilized primary and secondary data to examine brick kiln emissions' effects on the surrounding area's environment and public health. The collection of primary data was conducted in multiple zones within Savar Upazila, which is home to a significant number of brick kilns. The utilization of secondary data provided valuable insights regarding the toxic pollutants discharged by these kilns and the corresponding health risks they pose. The participants provided accounts of various health ailments, such as dermatological conditions, optical difficulty, and respiratory complications, further aggravated by brick kilns' incidents. The prevalence of crop losses, soil degradation, and reduced agricultural yields was confirmed by 74% of the respondents. The trees and crops in the surrounding area experienced adverse effects due to the deposition of dust particles. During periods of inactivity, the concentrations of sulfur oxide (SOx) were between 6 and 9 times lower compared to periods of operation. Similarly, nitrogen oxide (NOx) levels were observed to be 4 to 6 times lower during non-operational phases. The degradation of water quality in adjacent bodies has been attributed to the deposition of dust and ash originating from brickfields, resulting in substantial repercussions on aquaculture. A significant proportion of participants indicated experiencing diverse health issues, notwithstanding the employment prospects generated by brick kilns, thereby underscoring the adverse consequences on both the environment and the local economy.
