Lake-Cottage Housing Stock
Like several Chain O'Lakes communities, Island Lake has a mix of older lakefront cottages, some originally built for seasonal use, alongside newer year-round construction further from the water.
Older cottage-era homes converted to full-time use can sit on smaller-diameter laterals not originally sized for year-round occupancy.
Lake-Adjacent Drainage
Properties directly on the water can see different groundwater behavior than those set back from it, which is worth mentioning when describing a drainage issue.

A Village Built Around a Man-Made Lake
Island Lake straddles the border of Lake County and McHenry County, and its name comes from the lake at its center, which was created in the 1930s when developers dammed Mutton Creek to form a recreational lake with a small island. Summer cottages were built around the shoreline for Chicago-area families seeking weekend getaways, and the village incorporated in 1952 as more of those cottages became year-round homes. In later decades, subdivisions spread across surrounding farmland, and Island Lake grew into a small suburban community of several thousand residents.
Today the village includes converted lake cottages and older homes near the water, mid-century ranches and raised ranches, and newer single-family subdivisions built since the 1980s and 1990s. That range means plumbing varies considerably, from small, piecemeal systems in former cottages to modern PVC in newer homes.
Being split between two counties, Island Lake residents sometimes deal with different county services, but the village provides sewer service to most of its homes.
Former Lake Cottages
Homes near the lake that began as summer cottages often have plumbing that was added or expanded in stages, sometimes on crawlspaces or shallow foundations. Lines may be undersized for full-time use, and connections between original and newer sections can become clog points.
Many of these homes originally used septic systems before connecting to village sewer. Remnants of old septic connections or abandoned lines can occasionally complicate diagnosis.
A camera inspection maps where lines actually run and identifies weak points, which is especially valuable for converted cottages.
The Lake, the Creek and Groundwater
Island Lake's namesake lake and Mutton Creek keep groundwater high around the shoreline, and nearby wetlands add to wet conditions in spring. Saturated soil can shift around buried pipe, opening joints and creating sags, and groundwater can infiltrate cracked lines.
Basements and crawlspaces near the water may take on moisture during wet seasons. Sump pumps with battery backups, good grading and downspout extensions help keep foundations dry.
A camera inspection shows whether groundwater infiltration or settling is affecting your lateral.
Ranches, Raised Ranches and Newer Homes
Mid-century ranches and raised ranches in Island Lake may have partial basements or lower levels close to sewer elevation, sometimes with ejector pumps. Their laterals may be clay or early plastic.
Newer homes built since the 1980s use PVC drains and typically have full basements with sump pits. They resist roots and corrosion but still clog from grease, wipes and debris.
Knowing your home's age and layout helps the crew diagnose problems quickly.
Village Sewer and Backups
Island Lake's sanitary sewers are separate from storm sewers. During heavy rain, groundwater infiltration and improperly connected sump pumps or downspouts can overload the system and cause backups into homes.
A backwater valve protects your basement from sanitary sewer backups. Routing sump discharge to the yard, as local rules generally require, helps keep the system from overloading.
If several homes on your street back up at once, contact village public works.
Mature Trees Near the Water
The older neighborhoods around the lake have mature trees that now reach well over the rooftops of the original cottages. Their roots seek moisture, and older clay or early plastic laterals with loose joints are easy targets. Root intrusion tends to cause backups that recur every year or two at about the same distance from the cleanout.
Rodding with a root-cutting head clears the blockage, and a camera inspection afterward shows how many joints are affected. If damage is limited, a spot repair may solve the problem; if many joints are compromised, lining creates a new pipe inside the old one without digging up the yard.
When planting new trees, keep them well away from the path of the sewer lateral.
Winter and Spring Considerations
Cold winters can freeze plumbing in crawlspaces and unheated additions, a particular concern for converted cottages. Insulating exposed lines and keeping crawlspace vents closed helps prevent frozen and cracked pipes.
Spring thaws raise groundwater around the lake and creek, and sump pumps work hardest from March through June. Test your sump pump before spring, make sure the discharge line is clear and consider a battery backup. If drains slow after a hard winter, have the main line checked before the spring storms arrive.
Service in Island Lake
Crews serving the Lake and McHenry County border area cover Island Lake along with Wauconda, Lakemoor, Volo and Fox River Grove. When you call, share your address, the type of home and which fixtures are affected, and mention if you have a sump pump or ejector pump.
For main line clogs, the crew will rod from the most accessible cleanout. For converted cottages or recurring problems, a camera inspection is recommended. Pricing is confirmed on site before work begins.
Buying in Island Lake
For converted cottages and older homes near the lake, a sewer camera inspection before closing reveals the condition of the lateral and any unusual plumbing. Ask whether the home was ever on septic and whether abandoned septic components remain on the property. For newer homes, ask about sump and ejector pump age and whether the home has a backwater valve.
Also ask about flooding history, since properties near the water and creek can see high groundwater in wet years.
Everyday Habits
Keep grease out of kitchen drains, flush only toilet paper, use hair catchers in showers and keep the basement floor drain clear. Watch for early warning signs like gurgling drains, water rising in the tub when the toilet flushes or sewer odors, and call before a partial blockage becomes a backup.
Coverage Area
Local crews in our network serve the Village of Island Lake on both the Lake County and McHenry County sides, including the neighborhoods around the lake and Mutton Creek and the subdivisions along Route 176 and Darrell Road. Share your address and nearest cross streets when you call.
Living on a County Line
Island Lake's location on the Lake and McHenry County line occasionally causes confusion. Property taxes, building permits and some services depend on which county your home is in, but the village provides sanitary sewer service to most homes on both sides. If you are unsure who maintains the public sewer on your street, your water and sewer bill will identify the provider. Homes outside village limits nearby may be served by other districts or rely on septic systems. Knowing your provider matters when a backup affects several homes, since that is a public main issue rather than a problem in your own lateral, and the provider's public works staff should be notified right away.
When to Call
Call when several drains slow at once, when water rises in the tub as the toilet flushes, when a floor drain gurgles or when you notice sewer odors. Each points to a restriction in the main line, and calling early prevents a basement backup and costly cleanup in a finished lower level.

Is all of Island Lake covered?
Yes - the village's ZIP code (60042) is fully covered.
Does being on the lake affect drainage?
Properties directly on the water can see different groundwater behavior than those set back from it - worth mentioning when you call.
