Olak, errotak eta zentralak (eu)

Azalpen orokorrak

Beste toki askoren moduan, Soraluzen ere ura ustiatzeko hainbat bolu edota errota eraiki zituzten.

Lurra lantzerakoan orografiak asko laguntzen ez badu ere (ikus Soraluzeko mugak), herriko aldapek berebiziko indarra ematen diote urari, beren ustiaketa lagunduz.

Olak

Alboko herriekin konparatuz, Soraluzek badu alde honetatik berezitasuna. Esandako moduan, nekazaritzandako aukera larregi ematen ez zuenez, bertakoek industriari ekin zioten. Eta industriak ezer behar badu, indarra da. Beraz, sortutako errotak nekazaritzarako baino industriarako sortu zituzten gehien bat, armak forjatzeko; arma zuriak lehen eta suzko armak gero (ikus Armak eta lanabesak).

Batez ere bi ingurutan agertu ziren olak, Sagar-errekan (Errotabarri, barrena zaarra, Mutxan, Olabarrena) eta Olean (Agarreburu, Arkaitz, Egotza, Olea bera eta Txitxirriketa). Txara azpian, berriz, San Millán y Villalegre markesaren fragua zegoen.

Honetaz gain, Sagar-erreka bailaran Bolinegi izeneko erreka bada, eta Olea inguruan Bolu izeneko mugarria; biak ala biak erroten aztarnak, agian ola izandakoak ere aurretik.

Errotak

Armagintzaren beherakadarekin batera hainbat ola errota bihurtu zituzten, bere lana nekazaritzara bideratuz: Errotabarri eta Olea, esate baterako. Goian aipatutako Bolu ere multzo honetan sar zitekeen.

Honetaz gain, baserri inguruetan beste errotak ere sortu ziren: Armendia, Atziolatza Barri, Igarate, Iraolabeita, Malmero.

Zentralak

Ur ustiaketen bigarren loraldia elektrizitateak ekarri zuen. Gaur eguneko sare elektrikoak hedatu gabe zirenez, hainbat tokitan elektretxeak sortu ziren. Batzuk publikoak, herri osoari indarra ematen zienak; eta beste batzuk lantegiek sortutakoak, autokontsumorako. Garai honetan hainbat errota izandakoak indarra sortzeari egin zion: Errotazar, Malmero...

1960-70 inguruan, Iberduerok (orduko Iberdrolak) zentralak erosi eta itxi zituen, bezeroak bereganatzeko eta konkurrentzia desagertarazteko. Eta lortu ere: banaka banaka herriko zentralak itxi zituzten, eta hondatzen hasi ziren. Erori ala bota, gaur egun ez da bakar bat geratzen.

Salbuespen bakarra Elektrika da. EVEren laguntzaz Udalak erosi eta martxan jarri zuen, gaur egun oraindik polito dabil eta martxan.
