M/E Roundtable calibration and working properly. Generally there are more components to check and maintain when gray water recycling and rainwater harvesting are used, such as level indicators and alarms, pumps and valve operation, cleaning of the holding tanks, and any discharge areas such as hoses or irrigation sprinklers. Also, keep the systems clean to avoid unwanted bacteria or related growth in the standing water. The no-water urinal fixtures are cleaned much the same as conventional fixtures except the liquid seal layer—whether floating on top or in a cartridge type—must be regularly checked to ensure the seal is being maintained and there are no escaping sewer gas or odors. Care needs to be taken that any cleaning agents used do not harm the liquid seal. MARTIN: No-water urinals: Close adherence to manufacturer recommendations for cleaning of the urinal and replacement of the cartridges or sealant is essential to ensure that these devices continue to perform as designed. Gray water/rainwater: The use of gray water and rainwater for indoor purposes such as flushing toilets has been promoted in many green building venues. While this has approach has much potential, codes and standards have not yet been put in place to ensure that the water does not adversely effect the internal components of toilets. There are no applicable standards in the United States defining the quality of any gray water and rainwater used for these purposes, so the effect of any given gray water source on components cannot be predicted. Before using any reclaimed water for toilet flushing, work with a professional to put in place a system to perform basic filtering and sanitization. Rainwater: Harvesting systems should be cleaned and inspected regularly. Make sure that leaf and debris catchers are kept clean and that systems discarding the first flush of water are working properly. Also, clean the holding tank in accordance with manufacturers’ instructions to keep water quality and function high. Accurate billing isn’t easy without accurate information.
