Manteca overall water use is near pre-drought level

Manteca is consuming water almost at pre-drought levels.

The city’s 81,450 residents used 310 million gallons of water in November.  That compares to 310 million gallons in 2013 when Manteca had 71,203 residents.

Based on per capita consumption, each Manteca resident in November used 3,806 gallons for the month compared to 4,353 gallons in November 2013. Even though the overall city water consumption is almost the same, it is down 12.57 percent since 2013.

More telling of the historic trend of water use in Manteca is the fact Manteca’s November use peaked in 2007 at 314 million gallons. Manteca had 63,783 residents in 2007 that used 4,922 gallons per capita during November of that year. When compared to current year water use, Manteca per capita consumption is down 22.68 percent from 2007.

Most of the water use drop between 2007 and 2013 is attributed to mandated low-flow shower heads and toilets as well as water efficient washing machines.

The more recent low water use year for November when 263 million gallons of water was used by 75.195 residents in 2015 reflected a per capita consumption of 3,497 gallons. That’s 8 percent lower than the November 2018 water use.

Manteca’s water rules

uNo irrigation is allowed during or within 48 hours following measurable rainfall as defined by storms that generate run-off or puddles.

uNo watering is allowed on Monday or any day between noon and 6 p.m. Watering for even addresses is on Tuesday, Thursday, and Saturday while odd addresses can water on Wednesday, Friday, and Sunday.

uNo water will be allowed on any day at any time for washing off sidewalks, driveways, patios, parking lots or other exterior non-landscaped areas without a permit obtained from the Manteca Public Works Department office at the Civic Center.

uNo water will be allowed to flow into a gutter or other drainage area for longer than 5 minutes. All water leaks or malfunctions in plumbing or irrigation systems must be fixed with 24 hours.

Penalties include a written notice on the first violation, a $100 fine with applicable fees on the second violation that may be waived by attending a water conservation workshop; a $200 fine and applicable fees on the third violation; and $500 fines for each and every subsequent application plus applicable fees.
