For this reason, most commercial buildings, for example many hotels, schools or mixed usage community blocks now incorporate swimming pools and jacuzzis in their facilities, whilst public parks, farms, hospitals and malls may now require larger amounts of irrigation based on the new legislation. Even with new initiatives such as ground source heat pumps, or grey water recycling, when water leaks occur utility supplies will always be used to meet usage needs – that is when the cost of water leaks will result in customers investigating and repairing any possible water leaks which is more than likely going to be seen in an increased water bill at the end of the month.
