Quality and disinfection trials of consumption water in storage reservoirs for rural area in the Marrakech region (Assif El Mal)
Traditional reservoirs for water storage are important systems of water supply in rural areas of Morocco. These reservoirs are fed by rainwater and/or directly from rivers through open channels; the stored water is used without any treatment as drinking water by the surrounding population. The present study aimed to assess the physicochemical and bacteriological quality of stored water and the ...

Residential system design
Rainwater systems can be as simple as placing a rain barrel beneath a downspout or they can be complex – engineered multi-tank systems with pumping stations and automated computer controls for supplying commercial and industrial process applications. Consider that in one installation in the Sumo arena in Japan, rainwater is supplied for flushing toilets and the cistern’s excess ...

Hotel Grey Water/Process Water Reuse - Case Study
Issue/Challenge A large resort in Mexico wanted to minimize the cost of their potable and process water used in their operations. The company had been using a single pass RO system from a well water source which provided permeate water to their water storage tank. This system was inefficient, producing only 50% of clean water production with the remaining 50% being sent to the municipal sewer ...

Fast Response, Early Boost: Eliminate Ammonia Oxidizing Bacteria
Potable water storage tanks in chloraminated systems endure water quality problems, particularly during warm weather. A simple approach can solve these problems, enhance a facility's mixing system, and save money. Historically, attempts to solve water quality problems in chloraminated systems that use water storage tanks have been minimally successful. Many storage tank facility managers have ...

Avoid Hurricane Tragedies by Storing Potable Water
In the aftermath of Hurricane Maria more than half of Puerto Ricans lacked access to potable water. Since Puerto Rico is an island, supplies couldn’t simply be shipped over land. With ports and airfields damaged, supplies were slow to reach those in need. When Hurricane Irma hit Florida and Hurricane Harvey slammed into Texas, many people and organizations also found themselves scrambling ...
