New Haven drains through the year

Nor'easters and summer storms overload combined sewers and flood low basements, and roots grow fastest in summer.

Winter cold freezes back-porch plumbing and pipes on exterior walls.

Before the plumber arrives

  1. 1

    Alert the other apartments

    In a New Haven two- or three-family, everyone shares the basement line.

  2. 2

    Heavy rain or storm tide?

    If the street is flooding, the combined sewer may be pushing back.

  3. 3

    Check the basement

    Water around the floor drain or laundry sink is the usual first sign.

  4. 4

    Yale or SCSU rental?

    Call your landlord before calling a plumber.

Wooster Square and the Italian East Side

Wooster Square, with its row houses around a cherry-tree park, became the heart of Italian New Haven in the early 1900s, home to the pizzerias that made the city famous. Its row houses and multi-families have old laterals running under narrow sidewalks, and the restaurants on Wooster Street put plenty of grease into the system.

East Rock

East Rock, below the trap-rock ridge of the same name, has Victorian two- and three-families on tree-lined streets, many rented to Yale graduate students, postdocs and hospital staff. Big trees and old clay laterals mean roots, and heavy use adds wear.

Combined sewers

New Haven's older neighborhoods are served by combined sewers that overflow into the harbor and the Mill and Quinnipiac rivers during heavy rain. The regional authority has separated many sewers and built storage, but big storms can still surcharge local lines. Backwater valves protect basements.

Dwight, the Hill and Fair Haven

Dwight, the Hill and Fair Haven are dense neighborhoods of multi-family homes built for factory workers and immigrants, from Irish and Italian families a century ago to Puerto Rican, Mexican and Ecuadorian families today. Several households share each building sewer, and grease and wipes from busy kitchens and bathrooms cause most clogs.

A typical New Haven call

In September, the first-floor tenants in a 1900 two-family in East Rock find water around the basement floor drain after the upstairs tenants run laundry. The landlord's plumber opens the cleanout and clears roots from a big maple about twenty-five feet out. The camera shows the clay lateral cracked at two joints. The landlord books a liner.

Coastal neighborhoods

Morris Cove, the Annex and parts of Fair Haven sit on low ground near the harbor and the Quinnipiac River. Hurricane Irene and Sandy flooded parts of these neighborhoods, and storm tides still push water into low streets. Cracked laterals take in water, and basements see flooding.

Westville and Beaver Hills

Westville and Beaver Hills have single-family homes and two-families from the 1910s through the 1950s on hilly, wooded streets near Edgewood Park and West Rock. Long laterals under big trees fill with roots.

Pizza and restaurants

New Haven's famous apizza places on Wooster Street, the restaurants downtown around Yale and the taquerias in Fair Haven keep kitchens busy. Restaurants there keep grease traps pumped to stay open on busy weekends.

Students and turnover

Yale, Southern Connecticut State, Albertus Magnus and the University of New Haven bring tens of thousands of students and staff, many renting in older multi-families. Late August and early September bring a rush of clogs as new tenants move in.

Owners who have the line cleaned during the summer, while units sit empty, rarely get those early-semester calls.

Winter

New Haven winters bring nor'easters and cold snaps. Back-porch kitchens in old multi-families and pipes along exterior walls freeze first. Heat the basement and wrap exposed lines.

Prospect Hill and Whitney Avenue

Prospect Hill and the stretch of Whitney Avenue north of Yale have grand Victorian and Colonial Revival homes, many now owned by the university or divided into apartments for faculty and staff. Long laterals from deep front lawns run under enormous oaks and beeches, and roots are almost a given. Owners usually choose lining here to protect the trees and old stone walls.

Kitchen stacks in multi-families

New Haven two- and three-families usually stack their kitchens at the back, all draining into one cast iron kitchen stack. Grease from several households coats that pipe year after year, and it often clogs at the base in the basement. When the first-floor sink fills with dishwater from upstairs, jetting the stack usually clears it.

The Mill River and Wooster Square floods

The Mill River and the old creek beds under Wooster Square and Fair Haven sit on low ground where storm water collects. Heavy rain raises groundwater quickly, and cracked laterals in those neighborhoods take it in. A backwater valve on the building sewer is the best protection for a basement apartment there.

When you call

Share the neighborhood, the building type and age, how many units share the line and whether it's a rental. Mention whether it rained hard first.
