Irrigation meters are separate water meters used exclusively to measure water used for landscaping, yard irrigation, or filling swimming pools, provided that none of the water returns to the sanitary sewer system. Billing is based on water used. There are no sanitary sewer charges.
Special safety requirements for irrigation meters
A back-flow preventer is required on all irrigation meters to protect the public water supply against actual or potential contamination from cross-connection, backpressure, or back-siphonage. Please refer to MAWSS’ Cross-Connection and Backflow Prevention Program for more details on installation and testing.
Residential irrigation meters, that are less than 1” in size, are installed by MAWSS with a dual-check valve to prevent contamination of the public water supply. Annual testing of the device must be done by a MAWSS-approved and certified tester, hired at the customer’s expense. Failure to do so can result in termination of service.
MAWSS does not guarantee that a double-head irrigation meter can be installed at all locations requested. If conditions in the field create an additional expense, the customer will be notified and given the option to pay the additional expense or terminate the project with all prepaid fees being refunded.
Commercial or larger irrigation meters can be installed and tested by the customer provided they utilize a MAWSS approved backflow prevention assembly. Annual testing of the device must be done by a MAWSS-approved and certified tester, hired at the customer’s expense. Failure to properly install and annually test this device will result in termination of service.
Faucets, hose bibs and sprinkler systems are separate installations made by the customer, plumbing contractor, or landscaping/irrigation professional.
Irrigation meter accounts are charged a minimum bill of $12.71 per billing period regardless of whether any outdoor water has been used. Charges will appear as a separate line item on your bill.
