RCSD to hire treat­ment plant en­gi­neer

ROSA­MOND — With con­struc­tion un­der­way to re­vamp and ex­pand the Rosa­mond Com­mu­nity Ser­vices Dis­trict’s waste­water treat­ment plant, Dis­trict of­fi­cials are look­ing to hire a con­sult­ing en­gi­neer to en­sure it be­comes oper­a­tional as in­tended.

The Board of Di­rec­tors on Wed­nes­day will con­sider con­tracts with a firm for op­er­a­tions over­sight for the ex­pan­sion and to de­velop plans and poli­cies for com­pli­ance with the state re­quire­ments and those of the La­hon­tan Re­gional Wa­ter Qual­ity Con­trol Board.

The meet­ing be­gins at 6 p.m. in the Board Room of the Dis­trict of­fices, 3179 35th St. West.

The Board will con­sider two con­tracts with Bak­ers­field-based Aqua Op­er­a­tions. One will be for op­er­a­tion over­sight dur­ing the ex­pan­sion project, fo­cus­ing on such items as considerat­ions for test­ing and com­mis­sion­ing the plant and co­or­di­nat­ing per­mit re­quire­ments, and a sec­ond con­tract to de­velop the poli­cies and pro­ce­dures re­quired for its op­er­a­tion to meet reg­u­la­tions.

The to­tal cost for the two con­tracts, $39,335, is in­cluded in the over­all $15 mil­lion bud­get for the waste­water treat­ment plant project, ac­cord­ing to the staff re­port.

The re­vamped and ex­panded plant is ex­pected to open in spring 2021 with a new

name — The Rosa­mond CSD Wa­ter Recla­ma­tion Plant — to bet­ter de­scribe its ul­ti­mate pur­pose.

In ad­di­tion to han­dling the com­mu­nity’s waste­water dis­posal, the plant will recharge the un­der­ly­ing ground­wa­ter basin, pro­vid­ing ad­di­tional ground­wa­ter for the Dis­trict to pump.

The waste­water treat­ment plant project has been in the works for a cou­ple years as a means of ad­dress­ing more than one is­sue fac­ing the Dis­trict.

The Dis­trict has been un­der an or­der from the La­hon­tan Re­gional Wa­ter Qual­ity Con­trol Board since Novem­ber 2015 to re­duce ex­cess ni­trates seep­ing into the ground­wa­ter from wa­ter treated to a sec­ondary level at the waste­water treat­ment plant. The treated wa­ter is cur­rently sent to evap­o­ra­tion ponds on­site, which have been found to be leak­ing.

An op­tion to re­line the ponds was deemed to be too costly and this al­ter­na­tive was de­vel­oped.

This project will take the sec­ondary­treated efuent, run it through the some­what mod­i­fied ter­tiary treat­ment equip­ment to re­move ni­trates, then per­co­late the re­sult­ing wa­ter into the ground.

This is in­tended to not only re­solve the ni­trate con­tam­i­na­tion prob­lem with the reg­u­la­tors, but also recharge the aquifer, al­low­ing the dis­trict to pump more ground­wa­ter.

The project calls for in­creas­ing the higher­level treat­ment ca­pac­ity of the plant from the 500,000 gal­lons per day to 1.27 mil­lion.

Once it is fully oper­a­tional, the ex­ist­ing evap­o­ra­tion ponds will be cleaned of the “sludge” left be­hind and aban­doned.

Three new per­co­la­tion ponds, where the treated wa­ter will be al­lowed to soak into the ground, will be built as part of the project.
