Drainage and grading in Little Falls
Little Falls has stretches of low ground and a high water table, so drainage problems and seasonal flooding come up again and again here. That is why a good chunk of what we do here is drainage and grading.
When a yard will not drain, a basement keeps taking water, or a lot floods every spring, that is our wheelhouse: French drains, regrading, swales, and moving water away from the house for good. That is a big part of what we do here, but it is far from the only thing. We still handle sewer and water lines, septic, grading, driveways, and emergency digs across town.

The Passaic County highlands are rocky and wooded, with lake communities and plenty of septic and drainage work. Steep, tricky ground is where an experienced operator earns their keep.
As a township, Little Falls has the kind of larger properties where septic systems, grading, drainage, land clearing, and long driveways come up most. Whether it is an emergency sewer or water line dig-out, a septic system, a lot that will not drain, or a new driveway, we bring our own equipment and an operator who knows the ground in this part of Passaic County. We show up when we say we will, and we leave your property graded and clean.

What tends to be in the ground in Little Falls
Most of Little Falls went up in the 1950s, across roughly 5,748 housing units.
About 19% predates 1940, so there is a real pocket of clay and galvanized service in Little Falls sitting alongside much newer stock.
The bigger issue here is the 57% built between 1940 and the early 1970s. Orangeburg pipe was rated fifty years and routinely goes oval and collapses closer to thirty, so in a township weighted this heavily toward that window it is less a question of if than which street.
Housing-age figures: US Census American Community Survey 2019–2023 5-year estimates, table B25034. Pipe service lives are documented industry figures. What is actually under any one property varies, so we confirm it on site before we quote a replacement.
Nearly all of Little Falls is on public water
About 98.2% of Little Falls’s land area sits inside a public water purveyor’s delivery area, shared between 2 different systems. The largest is NJ American Water - Little Falls, then Township of Wayne. Sewer coverage tracks it closely, about 93.6% of the town, so most properties here are either on both or on neither. All of this is land area rather than houses, and a main running past a property does not mean the property is on it, since plenty kept the well after the main went in.

NJDEP maps actual delivery areas for public community systems, meaning fifteen or more year-round connections; smaller shared and association systems are real but do not appear. Percentages are share of land area, not share of homes, and a state file can lag a change of ownership. The name on your bill beats any map, including this one.
The part that changes the job here
Most of Little Falls is served by New Jersey American Water, with a piece on the Township of Wayne system, and sewer goes to PVSC. Which of the two water utilities an address is on decides who you call and whose rules apply to the line.
In April 2025 NJ American Water announced a $1.3 million job replacing about 2,500 feet of main on Wilmore Road between 1st Avenue and Prospect Street, and said it would replace any customer-owned service line identified as lead or galvanized. On an American Water street, the customer side of a lead or galvanized line is part of that program rather than a private repair.
Most of Little Falls is inside a sewer service area
About 93.6% of Little Falls’s land area falls inside a mapped sewer service area, treated at PVSC. A service area is where sewer is planned and permitted, not a promise that a main runs past your house, so the only way to settle it for one address is to look. Outside it, septic.
Sewer connections, laterals and septic work are all things we do, and which one you need is usually settled in one phone call. Sewer and water line work.
