Water Efficiency Calculations

Water EfficiencyComplete Sustainability calculate water consumption in accordance with regulation Part G of The Building Regulations. New homes are expected to get water efficiency to comply with part G of the Building Regulation and the Code for Sustainable Homes. They need a water efficiency calculator for the design stage and the ‘as built’ stage. According to the government’s national calculation methodology, the efficiency is calculated in litres per person. All new dwellings must have 125 litres of water usage per person ever day at most, in accordance with the part G of the Building Regulations. The Code for Sustainable Homes sets targets for water consumption figures based on WAT 1 levels. Levels one and two must consume 120 litres or less per day. Levels three and four are expected to consume 105 litres or less per day and levels five and six must consume 80 litres or less.

At Complete Sustainability Solutions, we are experts at assessing water efficiency. Our team can offer efficiency water calculations for all sectors within the UK. Our professional and experienced assessors can help you ensure that you meet the required limits. Apart from the water calculations, we offer advice on what can be done to increased efficiency. Our water efficiency calculations can help you predict water consumption and to comply with the regulations. Our calculations are fast and reliable. We will review and analyse the information you provide us before providing a report of our findings.

Please note, the water calculations are based on flow rate in the living areas and not on the total size of your property. We will provide you with totals for all water usage, so that you can calculate how much money is being spent per day in water bills.

New dwellings details stipulate that water efficiency is calculated as litres per dwelling by dividing the total water consumption of a property (metered and unmetered) by its number of dwellings.

Being mindful of the water efficiency of your property is now a key concern for making it sustainable. Complete Sustainability Solutions are experts in water efficiency and offer a comprehensive range of services to ensure your property has the best chance of complying with Building Regulations.

How To Improve Water Efficiency In Buildings

  • Use dual-flush valves for water closets
  • Use alternative sources of water such as rainwater. You can have rainwater harvesting systems installed to be able to avoid its wastage. You can recycle water where possible. It can be used for irrigation and some indoor uses.
  • Use water-efficient appliances including washing machines, dishwashers and taps. If your equipment is old, replace it with newer ones that consume less water
  • Watch out for water leaks in a building. Water leaks can lead to wastage of a lot of water especially when they go undetected for long periods. It is advised to keep a continuous surveillance on your building to detect leaks as soon as they occur
  • Perform regular water audits to help you determine what you can do to increase water efficiency. Water audits make it possible to understand how water is being consumed in a building. You can use water metering and submetering to monitor your water consumption. They can also be used to detect leaks.
  • Train the staff and occupants of a building on the importance and ways to conserve water. They should be able to adopt water-efficient practices and to report leaks when they notice them.

These calculations play an important role in dealing with water shortages in the UK.
