Due to the variation of pressure in the north of the Journalists colony of the city of Pachuca (Hidalgo), the Commission of Intermunicipal Water and Sewerage Systems (CMSIM), performed a series of maneuvers to detect the origin of pressure deficiency in the streets 15 and 16 September, 18 of July, part of the Madero avenue and José Ibarra Olivares street. Hence we can find the origin of the construction work of storm drains and lanes of Tuzobus located in the Juarez and Revolution avenues.

So the CMSIM conducted the review of all branches to locate not visible leaks, detecting the need of valves replacement which presented difficults when operating, in addition to the installation of 24 gauges in all streets and major intersections; performing acoustic monitoring of distribution networks, identifying high levels of noise that indicated no visible leaks.

For the rehabilitation of the water supply network there were installed TOM^® PVC-O pipes of DN110 mm to DN315 mm at pressures of 16 and 25 bar.
