Es­to­nia to build EURO 1.7 m worth of wa­ter sup­ply net­works

The Baltic Times - - BALTIC NEWS - BNS/TBT Staff

En­e­fit Kae­van­dused, a min­ing sub­sidiary of the state-owned Es­to­nian en­ergy group Eesti En­er­gia, in five years has built 50 km of wa­ter sup­ply net­works for 1.7 mil­lion Eu­ros in oil shale in ru­ral mu­nic­i­pal­i­ties, which has equipped more than 150 house­holds with wa­ter sup­ply.

Ac­cord­ing to the con­di­tions of the li­cense of ex­trac­tion of min­eral re­sources, En­e­fit Kae­van­dused is ob­li­gated to build an al­ter­na­tive wa­ter sup­ply for farms lo­cated in the area af­fected, as it is not in­con­ceiv­able that min­ing af­fects the nat­u­ral wa­ter regime, which could re­sult in the de­cline of the wa­ter level in drink­ing wa­ter wells, Eesti En­er­gia said.

"It is nec­es­sary for the safe min­ing of oil shale to redirect the wa­ter flow­ing into the mine, which can af­fect the wa­ter sup­ply of farms lo­cated in the area af­fected by the mine. We are con­stantly in­volved with mon­i­tor­ing the sit­u­a­tion and in co­op­er­a­tion with mu­nic­i­pal­i­ties, have found al­ter­na­tive so­lu­tions to en­sure that the res­i­dents of the min­ing area have a sup­ply of drink­ing and con­sump­tion wa­ter. The fin­ished projects in Iisaku and Il­luka are a good ex­am­ple of co­op­er­a­tion be­tween the lo­cal com­mu­nity and big busi­ness," Chair­man of the Man­age­ment Board of En­e­fit Kae­van­dused Ahti Puur said.

Puur said that each project is pre­ceded by ex­ten­sive prepara­tory work. "The or­der of car­ry­ing out work and the lo­ca­tion of bore­holes are de­ter­mined in co­op­er­a­tion with mu­nic­i­pal­i­ties. The depth of bore wells es­tab­lished by En­e­fit Kae­van­dused is up to 130 me­ters, the pump room is equipped with a wa­ter treat­ment sys­tem, which en­sures a qual­ity of wa­ter con­sis­tent with the de­mands of health pro­tec­tion."

Over 150 con­sumers have re­ceived clean drink­ing wa­ter dur­ing the projects car­ried out be­tween 2012 and 2017, including the Il­luka kinder­garten and ba­sic school and Il­luka cul­tural and com­mu­nity cen­ter. Ap­prox­i­mately 50 km of wa­ter sup­ply net­works and 9 bore wells have been con­structed. The to­tal cost of build­ing the wa­ter sup­ply net­works in oil shale ru­ral mu­nic­i­pal­i­ties was ap­prox­i­mately 1.7 m Eu­ros.

Af­ter hand­ing over the wa­ter sup­ply sys­tems to ru­ral mu­nic­i­pal­i­ties, the lo­cal gov­ern­ment is the one to han­dle their man­age­ment. Wa­ter sup­ply in the ru­ral mu­nic­i­pal­i­ties of Il­luka and Iisaku was car­ried out in co­op­er­a­tion with lo­cal gov­ern­ment and a num­ber of plan­ning and con­struc­tion com­pa­nies.
