N13 Sanitaryware Appliances

N13 Sanitaryware Appliances:
About: 


Consider:

  • A good high flow gravity fed shower to discourage retrofitting of power shower
  • Making all disabled toilets unisex to provide more toilets for females
  • Making baby change unisex and not occupying a toilet, to provide more toilets for females

TAPS:

  • Taps offer opportunities for reducing water demand
  • Proximity detection taps will only operate when hands are present
  • Because there are no taps to turn on, soap residues on taps they do not need cleaning so frequently or extensively
  • Aerated taps use considerably less water whilst not appearing to do so
  • Water reducing valves should be fitted to all appliances to reduce high mains pressure to an appropriate flow, so when a tap is open full bore the water is sufficient to rinse hands rather than fill a bath
  • Two stage taps can offer low flow in first position and high flow in second position
  • Water reducing/isolating valves can be fitted to all appliances to reduce waste when systems would otherwise need to be drained for maintenance

URINALS:

  • The decision not to use urinals will increase the demand on water from toilet flushes
  • Urinals create a high demand for water, all of which is drinking quality
  • Waterless urinals require no water at all and only use an oil cartridge to seal sewer gas from the room
  • Conventional water urinals can be proximity detection to flush only after a person has been present and has left

TOILETS:

  • Toilets create a high demand for water, all of which is drinking quality
  • Low or dual flush toilets use less water than their conventional alternatives, flushes can be reduced from 9 litre to 6, 4, 2 and even 1 litre flushes with syphonic drainage.
  • Assuming some visitors use the toilets less than once and others might use them more than once assume an average of 1,000,000 uses x 5 litres reduction (9 down to 4) = 5000 m3 of drinking quality water saved per year from toilet flushes alone
EAM Environmental Assessment Methods:
  • AECB have a water standard that is practical and realistic
  • AECB water standard as an alternative to BRE’s Code for Sustainable Homes and EcoHomes or BREEAM
PASS:
  • Product Assessment Sustainability Screening

Avoid:

  • Overnight water flushing on an automatic urinal flushing system must be avoided
  • Taps that can be left running
  • Taps running at full bore full pressure, if nor required
  • Water hammer noise from pipes
  • Noise from push taps closing on high pressure pipes
  • Taps that require pressure boosting pumps
  • Power showers
  • Inadequate showers that people would retrofit with a power shower
