cool product of the month: caroma waterless urinal and dual flush toilet

watersense_logo_colorthis month’s COOL product is actually one company, two products. the company is caroma and the products are their waterless urinal and dual flush toilet. caroma is an australian company that has been dealing with drought issues for years and they are genuinely committed to the environment and helping the world conserve resources, namely water. you can click to read their eco-statement. you can also review several tutorial videos on their website as well.

i recently installed both the waterless urinal and the dual flush toilets in the westbourne project. H2Zero_2the waterless urinal is coroma’s h2 zero model and it really is a waterless urinal. it has a “bio-seal”, a one way air-tight valve to seal the cartridge from the drainage system. it also includes a special tool that allows for hands free periodic replacement of the bio-seal. the manufacturer suggests replacement every 9-12 months. this is a great product and it will save the homeowners 4800 gallons of water a year.

the dual flush toilet is coroma’s caravelle and gives you the option of 2 types of flushes. flush #1 uses .8 gallons and flush #2 will use 1.6, a normal amount for a low flush toilet. Caravelle-One-Piece-mdfrom my understanding, a homeowner would be using flush #1 a majority of the time, so there would be substantial water savings there as well. when i combine the waterless urinal and dual dlush toilets installed in the westbourne project, the homeowners would be saving more than 7000 gallons of water per year. now, that may not seem like a lot, but water is a precious resource and every little bit helps. i’d say saving 7000 gallons a water a year without really doing anything different, is a good thing.

i’m going to be on the level with you here. you wouldn’t necessarily install these products to save money. because water is so cheap (that’s another topic) the return on investment is many years. the caravelle sells for about $750 per toilet versus $100 for a home depot toilet and $500-$600 for a nicer one piece low flow toilet. the waterless urinal will cost about $750 and the bio seal kit will cost about $115 once every twelve months. BUT, these are not  products you purchase and install to save money. you buy them to save a very precious, finite resource…fresh water.  a little bit can go along way. if a family of 4 can save 15,000 gallons of water per year,  imagine what that would mean if a these were installed in every home in your neighborhood. assuming 100 houses, that would be 1.5 million gallons of water saved per year. 1000 homes could save 15 million gallons of water. now that, is pretty COOL.
