“…There was a large variation in the volume of water applied by these systems, with microjet applying the most water and fixed sprinkler lawns applying the least amount of water on a per unit area basis. A number of studies have demonstrated significant water saving benefits of using controllers such as automatic timer, automatic timer with rain sensor, automatic timer with soil-water sensor and evapotranspiration controller for irrigation scheduling (Al-Ajlouni et al 2012;Dobbs et al 2014;Davis, Dukes 2014;Haley, Dukes 2011;McCready, Dukes 2011).…”

Abstract. Trinitrotoluene (TNT), a commonly used explosive for military and industrial applications, can cause serious environmental pollution. 28-day laboratory pot experiment was carried out applying bioaugmentation using laboratory selected bacterial strains as inoculum, biostimulation with molasses and cabbage leaf extract, and phytoremediation using rye and blue fenugreek to study the effect of these treatments on TNT removal and changes in soil microbial community responsible for contaminant degradation. Chemical analyses revealed significant decreases in TNT concentrations, including reduction of some of the TNT to its amino derivates during the 28-day tests. The combination of bioaugmentation-biostimulation approach coupled with rye cultivation had the most profound effect on TNT degradation. Although plants enhanced the total microbial community abundance, blue fenugreek cultivation did not significantly affect the TNT degradation rate. The results from molecular analyses suggested the survival and elevation of the introduced bacterial strains throughout the experiment. Keywords: TNT, bioaugmentation, biostimulation, phytoremediation, microbial community.

“…There are several useful tools available to improve irrigation application including rain sensors, soil moisture sensors, and evapotranspiration controllers (McCready and Dukes, 2011). For example, McCready et al (2009) reported that water use was reduced by 7 to 30% using rain sensors, 0 to 74% using soil moisture sensors, and 25 to 62% using ET based sensors when compared to a typical time based irrigation set to irrigate 2 days a week.…”

“…The amount of water allowed to leave the root zone without causing plant stress is the readily available water, RAW (m), [37]. Irrigation should be applied when the water level drops by a percentage known as the maximum allowable depletion, MAD (%), which is the amount of water relatively easily extracted by plant without causing plant stress [28].…”

The management of energy and water is increasingly gaining attention among domestic end-users. In developing countries, potable water supply is unreliable leading to alternative strategies such as rooftop water harvesting (RWH), storage and pumping. Since urban garden irrigation is the highest outdoor water consumer, optimal scheduling is important to conserve energy and water over conventional lawn irrigation methods. A model to optimally control the lawn irrigation was developed with the simulation results showing 17.4% potential water savings when using water directly from municipal sources. With RWH of a 1-hr event with 1-mm rainfall from a 120-m 2 roof, the model can potentially save 23.4% of water and 73.8% in energy costs per day. Such savings are important in reducing the demand for existing water and energy sources as well as greenhouse emissions. Further, this paper looks into two strategies to maximize the pump's life through minimizing the maintenance cost.Keywords: buildings, energy, optimal scheduling, rooftop water harvesting, time-of-use tariff, water
