Monthly Service Charge (up to a 1 " meter): $7.50

Commodity charge:
IRWD uses a five-tiered rate structure which rewards conservation. Water allocations are based on number of residents, landscape square footage and actual daily weather and evapotranspiration (ET) data for your area. Evapotranspiration is the amount of water that travels through turfgrass, and therefore the amount of water required for turf grass to be healthy and attractive. Turfgrass is the highest water-using plant in a landscape. Trees and shrubs use far less water than turfgrass, but IRWD's allocation system assumes that your entire landscape is covered in turfgrass. Therefore, your allocation contains more than enough water to meet the demands of your landscaping. Variances are available for larger than normal landscaped areas, more people living in the home or special medical needs. For additional information, please contact the District at (949) 453-5300.

Lake Forest Area (formerly LAWD)
Monthly Service Charge (up to a 3/4 inch meter): $9.60

Commodity charge: $1.55 per ccf*

Santiago Canyon Area (formerly Santiago County Water District)

Monthly service charges vary depending upon the size of the meter installed at the customer's connection. The lowest monthly service charge is $15.95 for a 5/8" meter. The base commodity rate is $2.16 per ccf and excess tier rates are charged for water usage in excess of allocated amounts.

Pumping Surcharge
A surcharge will be added to the commodity rate of those users who reside at higher elevations and cause the District to incur additional pumping costs to supply their water. The surcharge is based upon prevailing energy costs and currently varies from $.16 to $.42 per ccf depending upon the elevation of the area served. If you live in an area affected by a pumping surcharge it will be itemized on your monthly bill.

Wastewater System Charges (Sewer Rates)--Single Family
Newly established residential accounts are charged a sewer rate of $13.80 per month. Water usage is reviewed each year on December 31 and when an account has established a 12-month history, sewer rates are adjusted accordingly. As a results, customers who use low volumes of water are charged lower sewer rates. For example, after the annual review, customers using an average of 0-5 ccf of water per month pay a $10.35 sewer rate, customers using an average of 5.01-10 ccf of water pay a $12.40 sewer rate; and customers who use an average of more than 10 ccf remain at the $13.80 monthly sewer rate.

A portion of Newport Coast pays $4.75 per month for sewer collection fees.

Customers in the former Santiago County Water District area use septic tanks and therefore do not pay a sewer charge.

Certain parts of the IRWD service area receive sewer service from other agencies and therefore do not see a sewer charge on their IRWD bill.
