SharePoint 2016 Logs getting bigger

Hi All, 

The Last two day SharePoint Logs has been increasing significantly. 

I did run below. 

Now i am running out of space. 

I did user Sp-web.  and .Dispose();

Any help Thanks.

if($ps -eq $null)
{
Add-PSSnapin "Microsoft.SharePoint.PowerShell" -ErrorAction SilentlyContinue
}
$NewCSVObject = @()  

##########################Get-User Groups---###########
 $web = Get-SPWeb "https://mysite/site/subsite"
  foreach ($group in $web.groups){
write-host -foregroundcolor white "----Collecting users from group:"$group.Name "..."
foreach($user in $group.users) {
  if ($user.Loginname.StartsWith("SHAREPOINT\")) {continue}
  if ($user.Loginname.StartsWith("NT")) {continue}

   
    write-host -foregroundcolor Yellow "-------User:"$user.DisplayName + $user.UserLogin +  $group.Name
     $assocatedSiteObject = New-Object PSObject 
   $assocatedSiteObject | add-Member -MemberType NoteProperty -name "DisplayName" -value $user.DisplayName
   $assocatedSiteObject | add-Member -MemberType NoteProperty -name "Login" -value $user.UserLogin
   $assocatedSiteObject | add-Member -MemberType NoteProperty -name "SP Group Name" -value $group.Name

   $NewCSVObject +=$assocatedSiteObject
}
  }
  $web.Dispose();

  $NewCSVObject | Export-CSV "E:\TeamLMI\SiteUsrs.csv" -NoTypeInformation
