Sixty Years of Growth, and the Utilities Are Behind It
Willard has grown almost without pause since 1960, when it had 357 people. It hit 1,018 by 1970, 1,799 by 1980, 3,193 by 2000, 5,288 by 2010 and 6,344 at the 2020 census. That is a town that has roughly doubled twice within living memory, about fifteen minutes north of Springfield.
The infrastructure has not kept pace. After more than a decade of expansion, Willard's water and sewer systems are at capacity, and the city took a proposed water and sewer rate increase to residents in December 2025. Some properties are converting from septic to city sewer as service rolls out, and others are staying on septic for the foreseeable future because the main is not coming their way soon.
Two Growth Waves Means Two Failure Schedules
The practical effect of that growth curve is that Willard has two distinct populations of septic systems. The 2000s and 2010s wave, when the town went from 3,193 to 6,344, put in systems that are now 15 to 25 years old, which is exactly when concrete baffles start to spall and original effluent filters get cleaned for the first time.
Behind that sits an older rural population of systems installed when Willard was a village of a few hundred, on parcels that were never intended to be surrounded by subdivisions. Those are the ones where the tank location has been lost, no riser was ever installed, and the first service call includes an hour of probing to find the lid.
Greene County Rules Apply, Including the 72-Hour Clock
Willard permits through Greene County Building Regulations, not Christian County. That means new system designs must be signed by a soil scientist, professional engineer, registered sanitarian or geologist, soil factor analysis must be done by a soil scientist, and installers must hold current certification with both Greene County and the Missouri Department of Health and Senior Services.
It also means the 72-hour rule: any modification or replacement of an existing system requires the tank to be pumped and inspected within 72 hours before construction begins. If you are timing a septic repair against a possible sewer connection, that window is worth knowing about before you schedule anything, because it is the piece that most often has to be redone.
