Water restrictions would be considered when water usage was sustained above 50,000 m3/day.
Restrictions have not been needed since water meters were introduced in 2000.
Council said the trend of pressure on Tauranga water supply would continue until the Waiari Water Supply Scheme came online in 2021.
The graph pictured revealed how Tauranga's water demand was tracking compared with previous summers.
It shows water usage peaking much earlier in 2016/17 than in 2014/15 or 2015/16.
The seven day rolling average smoothed out any day-to-day water operations spikes and provided a good indication of how the demand was changing in response to changing weather.
WAIARI WATER SUPPLY SCHEME - it is a new water processing plant to meet Tauranga's growing needs - the water project involved the development of a new water supply intake from the Waiari Stream, a water processing plant in No 1. Rd Te Puke and a water pipeline from the plant to Papamoa - it is expected the water demand from Mt Maunganui and Papamoa will exceed the supply available from existing pipelines in the next 10 years - construction is expected to start around 2018 and be finished around 2021
