Plumbers in Grand Terrace, CA

The Blue Mountain City

Grand Terrace is a small hillside city in San Bernardino County along I-215, between Riverside and San Bernardino and only about 8 miles from Riverside in a straight line. It incorporated in 1978, and the 2020 Census counted 13,150 residents. Blue Mountain and its trail rise to the east, the La Loma Hills sit to the west, and the Agua Mansa industrial corridor lies nearby. Barton Road is the main street through town.

Water and wastewater

The city names Riverside Highland Water Company as the water company serving Grand Terrace. Despite the name, it is not Riverside Public Utilities, so a leak at the meter or in the street goes to Riverside Highland, not to RPU. Hardness figures for its water were not available here; Inland Empire water is generally hard enough to scale up water heaters and fixtures, and the company's water quality report is the place to check.

Grand Terrace wastewater is treated at the City of Colton's water reclamation plant, which accepts flow from both cities. The agency that maintains the local collection lines in Grand Terrace can vary, so for a backup in the street, start with the city.

Older homes

About 56 percent of Grand Terrace homes were built before 1980, and the median year built is 1978, with most construction in the 1960s, 1970s and 1980s. Many houses can still have galvanized supply pipe, cast iron drains and aging clay or cast iron sewer laterals. Repiping, drain line repairs and lateral camera inspections are a regular part of plumbing work here, along with water heater and fixture replacements.

Permits cover more than you might expect

The City of Grand Terrace Building & Safety, at 22795 Barton Rd., states that water heaters, re-piping, water softeners and fixture replacements or installations such as sinks, toilets and shower valves all need a permit.

Grand Terrace versus Riverside

Riverside homes use Riverside Public Utilities for water and the City's sewer system, and the City of Riverside allows simple water heater change-outs over the counter. Grand Terrace uses a private water company and sends wastewater to Colton, and its permit list is broader.
