During a shower, a shower heat exchanger from Dutch Solar System can recover more than half of the thermal energy from the heated drinking water. Under a positive condition, installing shower heat exchangers might lead to a reduction of 54 kton CO2 per year in Amsterdam. The research proves the efficiency and potential of the shower heat exchanger, by carrying out experiments in the laboratory and collecting data from the Uilenstede project site, a student housing estate near Amsterdam.

Household Water Treatment and safe Storage (HWTS) systems aim to provide safe drinking
water in an affordable manner. The effectiveness of these systems to remove pathogens is crucial for the health of its users. Different researches report wide ranges of effectiveness for each of the three selected systems: SODIS, ceramic and biosand filters. The resources available for the prices of HWTS also report wide ranges. In the data available no relation was observed between price and effectiveness.

For centuries free chlorine has been effectively used as a disinfectant to prevent the spread of water-borne diseases. Studies have found that a minimum of 0.2 mg L−1 of chlorine should be maintained within the distribution system so as to prevent any risk to human health. However, maintaining 0.2 mg L−1 of free chlorine within the distribution system is a challenging task. Addition of high-dose chlorine lends the water an odour and leads to other health-related problems to upstream consumers.
