Resolve the record before anyone quotes a trench
Where a record is unknown, the fix does not involve a plumber or an excavation. Enter the address on the authority's service material map, and where it returns unknown, send color photographs of the water service pipe where it comes into the building and the portion up to the meter, or take the five minute visit from an authority employee. In a village where nearly nine records in ten are blank, that is the highest value free step available, and it turns an estimate based on the age of the street into a price based on your own pipe.
Unknown means unlooked at, not condemned
One confirmed lead line in the village and none at all in the town is the context. The blanks reflect the pace of identification rather than anything found, so the honest reading is that the question is open rather than that the answer is bad.
Older housing raises the odds in the village core
The village runs a median build year of 1952 with 38.4 percent of homes built before 1940, against a town median of 1963 with 31.8 percent. Age is the reason identification is worth doing here rather than assuming a newer material.
Excavation rules are county wide
Minimum cover for a domestic water service is 54 inches, a permit comes before any work except an emergency, and nothing may be covered, backfilled or concealed before Plumbing Control has inspected it. Proximity to the treatment plant changes none of that.

OCWA publishes a Service Material Inventory Map where a customer can enter an address and see the service line material OCWA holds on record for that property. Where the record is unknown, OCWA asks for color photographs of the water service pipe where it comes into the building and the portion up to the meter, submitted through an online form, and offers a five minute home visit by an OCWA employee to help identify the material, arranged on 315-455-7061 extension 3139.

Section 5.5 of the Onondaga County Requirements for Implementation sets minimum cover for a building domestic water service with normal flow at 54 inches, sets building sewers at 48 inches minimum cover, sets pumped sewers and force mains at 6 inches more than frost depth which it gives as 48 inches minimum cover in Onondaga County, and sets fire service lines, yard piping and lines with little or no flow at 66 to 72 inches. It adds that designers and contractors should allow extra cover for local conditions such as wind exposure and large paved areas.

What water service lines involves


The treatment plant is here, and the pipe record is not
OCWA's Otisco Lake Water Treatment Plant sits in Marcellus and supplies the town and the village, and the village still has the least documented service line stock in the metro. Of 657 records under Village of Marcellus, 570, that is 86.8 percent, are unknown, against 41 galvanized requiring replacement and one confirmed lead line. The surrounding town is better documented, with 1,575 records holding 906 confirmed non lead, 36 galvanized and no confirmed lead at all.

Is your Marcellus record one of the 570 blanks?
Send the address and we will tell you what is published before anyone prices an excavation.
Marcellus service line questions
How can the village be so undocumented when the treatment plant is here?
They are unrelated. The Otisco Lake Water Treatment Plant in Marcellus treats and supplies the water, while the service line inventory is a record of what individual private connections are made of, which is built up address by address. Of 657 records under Village of Marcellus, 570 are unknown, which is 86.8 percent and the highest share in this metro. The surrounding town is much better documented, with 906 of 1,575 records confirmed non lead. Your own record is resolved by a photograph or a short visit rather than by anything the plant does.
Should I replace a service line that is unknown but working?
Identify it first, then decide, and usually the answer at that point is no. A working service that turns out to be non lead needs nothing. A service that turns out to be galvanized requiring replacement is a planning matter rather than an emergency, and the symptom to watch for is flow that fades at the furthest fixture while pressure at the hose bib stays sound. Since identification costs nothing and replacement is a substantial excavation, doing them in that order is simply cheaper.

Pressure that dropped, a wet patch in the yard, or a record you want read. No obligation either way.
