San Martín del Tesorillo improves its water network with two works

The water that reaches San Martín del Tesorillo does so with less need for pumping and with better-controlled pressure. Arcgisa has completed two actions on the municipality's supply system, which together total an investment of 251,126.05 euros, VAT included, according to the Mancomunidad del Campo de Gibraltar. The main intervention, of 213,537.50 euros (VAT included), consisted of installing a new pressure regulation system at the entrance to the tank in the northern area. To this end, a 500-millimetre-diameter by-pass has been built on the 800-millimetre main pipeline that carries water from the Estación de Tratamiento de Agua Potable (ETAP) de Arenillas to the San Enrique tank. The installation incorporates two hydraulic valves, one pressure-sustaining/reducing valve and another to maintain pressure and control the filling of the tank with a slow closure. It is completed with filters, shut-off valves and auxiliary elements. The works have included a reinforced concrete chamber measuring 8.60 by 4.10 metres with 2.75 metres of clear height to house the equipment, with eight independent liftable covers on its roof.

The second action, of 37,588.55 euros (VAT included), connects the 800-millimetre main pipeline from the ETAP de Arenillas with the 200-millimetre pipe that supplies the municipality, by means of a new 300-millimetre pipeline in the area around the San Enrique tank. This makes use of the pressure available in the main pipeline to carry the water to the town without breaking the head in the tank. This reduces the use of the pumping system located opposite these facilities and the associated energy consumption. The two works are complementary: one improves the regulation and control of pressure at the entrance to the tank and the other optimises the connection between pipelines.

The same agreement includes the purchase of an open-box truck for waste management, awarded for 161,280 euros, VAT excluded. The vehicle represents a new provision of material resources for these services in the municipality. The three investments fall within the Plan para el Campo de Gibraltar and the aid of Real Decreto 998/2024, of October 1, to improve hydraulic infrastructures and waste management in the region. Within the 2024 agreement, San Martín del Tesorillo has a maximum subsidy of 258,000 euros.
