Leak Detection in Phoenixville, PA

Phoenixville’s own water system, and the 2019 Aqua sale

Phoenixville is one of the few boroughs in the area that still owns its water treatment plant. In December 2019 it sold the part of its distribution system serving parts of East Pikeland, Schuylkill and Upper Providence townships to Aqua Pennsylvania, while keeping the plant and distribution inside the borough.

The borough’s law firm summarized the deal: the sale to Aqua closed December 4, 2019 for $3.46 million after PUC approval in October. About 550 customers in those three townships moved to Aqua, and 21 Upper Providence customers went to Pennsylvania American Water to sort out overlapping pipes. Aqua agreed to keep buying water from the borough plant through at least 2026.

The borough plant also feeds neighbors. A Delaware River Basin Commission docket for Pennsylvania American Water lists three interconnection points with Phoenixville supplying its Royersford district.

We could not confirm the borough’s published service line ownership rule. Most Pennsylvania systems put the split at the curb stop, but call the borough water department to confirm before repair work starts.

French Creek, the Schuylkill and the Ida flood

Phoenixville sits where French Creek meets the Schuylkill River, and both carry floodwater. During Ida in 2021, flooding badly damaged Aqua’s Pickering water plants near Phoenixville. After high water, a damp basement may be leftover flooding or a real leak that the flood started.

French Creek splits the borough into north and south sides, and the Schuylkill forms most of its northern and eastern edge, per its profile. When Ida hit, 6abc reported major damage at the Aqua Pickering plants beside the Schuylkill and Pickering Creek. Aqua’s president said the river had not flooded like that since 1869, and Aqua asked customers across four counties to conserve while Pickering West was repaired.

Flood or leak? How a technician tells

• Meter test with everything off. Floodwater does not move the meter.
• Moisture readings over several days. Floodwater dries; a live leak stays wet.
• Pressure test on the supply piping.
• Camera inspection of the sewer lateral if drains back up when the river is normal.

For leaks under the floor, see slab leak detection. For drains, see sewer lateral and drain leak detection.

Leak detection services in Phoenixville

Phoenixville calls tend to involve old service lines, hidden leaks in plaster and brick, basement floor leaks, leaks in converted mill buildings and apartments, and freeze damage. Each has its own method, chosen from what you describe on the phone.

Service lines. Acoustic listening and tracer gas locate the leak from the surface. See water service line leak detection.

Walls and ceilings. Moisture mapping and thermal imaging find leaks behind plaster without opening the wrong wall. See hidden wall and ceiling leak detection.

Basement floors. See slab leak detection.

Condos and mixed use buildings. Commercial and multifamily leak detection traces shared risers to the right unit.

Showers and tubs. In older bathrooms, shower pan and tub leak detection separates a failed pan from a supply leak.

What a leak costs on a Phoenixville area water bill

On Aqua’s Phoenixville rate zone, effective February 22, 2025, water costs $6.66 per 1,000 gallons for typical home use, plus a $7.35 monthly service charge. A running toilet adds about $29 a month. A cracked line at 1.5 gallons a minute adds about $432 a month.

Those rates are from Aqua’s Phoenixville rate zone notice and apply to Aqua customers in that zone, mainly the former borough customers outside town. Borough customers pay the borough’s own rate; use the gallons column with your bill. Aqua states it does not offer leak adjustments in Pennsylvania.

Arithmetic: gal/min x 60 x 24 x 30 = gallons; gallons / 1,000 x $6.66. Water only; sewer is separate. Excludes taxes.

Detection itself typically runs about $150 to $600 nationally. We quote on the phone. The borough water system is municipal, so the PA PUC generally does not regulate its rates. See high water bills in Pennsylvania.

Chester County is one of the counties NBC10 named where karst is notable. Pennsylvania DEP lists leaking water and sewer pipes as one cause of sinkholes, so a persistent leak on karst ground deserves quick attention. Read more in sinkholes and water leaks in Pennsylvania.

Quick checks before you call

Three checks take about 20 minutes: watch the meter with everything off, dye test each toilet, and walk the line from the curb to the house looking for wet ground. If water is spraying, close the main valve first, then call.

1. Turn off all faucets and appliances. Watch the meter for 15 minutes.
2. Add food coloring to each toilet tank. Color in the bowl within 10 minutes is a leak, per the EPA.
3. Walk from the curb box to the foundation looking for soft ground or a damp patch.
4. Check under sinks, the water heater and washer hoses.
