Quality of Water01:19

Quality of Water

89
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...

Design Example: Sustainability in Concrete Building

161
As the construction industry moves towards more eco-friendly practices, concrete's adaptability and its ability to incorporate sustainable features make it a key material in the drive towards greener building solutions.
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground...

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

41
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

Testing Water Quality01:14

Testing Water Quality

103
When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...

Design Example: Designing a Residential Plumbing System

664
The design of residential plumbing systems requires carefully evaluating water demand, flow rates, and pressure dynamics to ensure both efficiency and reliability. The nature of water flow within pipes is defined by its Reynolds number, which classifies flow as either laminar (smooth) or turbulent.

Waterproofing and Anti-Bacterial Admixtures in Concrete01:22

Waterproofing and Anti-Bacterial Admixtures in Concrete

75
Concrete's susceptibility to water absorption is due to the capillary action within the pores of its hydrated cement paste. This action draws water in, creating the need for waterproofing admixtures to prevent such penetration. The efficacy of these admixtures is contingent upon the water pressure, with variations arising from different conditions such as rain, capillary rise, or hydrostatic pressure in structures intended to hold water.
Waterproofing admixtures render concrete hydrophobic,...

Area of Science:

  • Environmental Science
  • Microbiology
  • Public Health

Background:

  • Premise plumbing systems can degrade water quality, leading to health risks from pathogens like *Legionella pneumophila* and exposure to contaminants.
  • Common interventions include flushing, thermal disinfection, and adjusting water heater temperatures.

Purpose of the Study:

  • To evaluate the effectiveness of flushing, water heater temperature adjustments, and combined interventions on water quality in a *Legionella pneumophila*-colonized building.
  • To monitor microbial and physico-chemical parameters before and after controlled management interventions.

Main Methods:

  • Monitored microbial (culturable *L. pneumophila*, *L. pneumophila mip* gene, cATP) and physico-chemical (pH, temperature, disinfectant residual, DBPs, heavy metals) parameters.
  • Implemented and assessed three interventions: flushing, water heater setpoint change, and a combined approach.
  • Correlated water quality changes with building occupancy data (Wi-Fi logins).

Main Results:

  • Flushing alone significantly reduced cATP and *L. pneumophila* but increased chlorine, iron, and disinfection by-products (DBPs).
  • Increasing water heater temperature alone led to increased copper levels.
  • Combined interventions showed increased chlorine and iron, but no significant reduction in *L. pneumophila*.

Conclusions:

  • Short-term or incompletely implemented interventions may not sufficiently improve overall premise plumbing water quality.
  • Logistically intensive interventions necessitate the development of more effective, holistic approaches for preventative and corrective water quality management.
