Hi, not really. Same load to plant, lower flow but higher concentration. All a normal urinal does is dilute the BOD, but the overall quantity in kg/lb remains the same.
Same as low flow toilets, less water in collection system = more backups = more maintenance = greater cost to utility. Thank you environmentalist.
In a lot of systems, there is already a problem brought on by the 1 gallon flushes from the old method of three gallons. There is NOT Enough water in these systems now and to go the next step will cause even more problems.
