Castellterçol is a historic and stately highland town in the Moianès region, situated on the high plateau at an altitude exceeding 700–760 metres in a strategic mountain location bordering the Vallès Oriental, Osona, and Bages, contiguous with Moià, Castellcir, Sant Quirze Safaja, Granera, Monistrol de Calders, and Gallifa. Its urban fabric boasts a distinguished architectural legacy centered on Plaça Vella, Plaça de Prat de la Riba (the birthplace of Enric Prat de la Riba and home to the Casa Museu), Carrer de Baix, Carrer de Dalt, Carrer del Mig, and the imposing 17th-century Baroque church of Sant Fruitós with its slender bell tower. Overlooking the town stands the historic Castell de Castellterçol (9th–12th centuries set on a rocky outcrop, featuring the Romanesque chapel of Sant Miquel), surrounded by centuries-old farmsteads such as La Ginebreda, La Teuleria, El Vilar, and Sant Llogari de Castellet. To eliminate unnecessary demolition in Castellterçol, we pinpoint hidden leaks using cutting-edge acoustic technology: high-gain electroacoustic listening sensors, non-combustible technical leak testing instruments.
The continental municipal supply carries a high mineral hardness of 28-36 ºfH creating scale buildup in boilers, while winter conditions feature thick freezing fogs and thermal inversions reaching -6 ºC. We provide 24/7 technical emergency coverage with response times under 20 minutes via C-25. Regarding wastewater clearing and jetting, we utilize mobile vans fitted with 200-bar continuous jetting units and motorized mechanical augers for collapsed gullies, while on distribution boards our electricians install Class A 30 mA super-immunised RCDs under REBT compliance and resolve earth-leakage faults.
