Help with "until" loop

Here is the complete sketch that I had been attempting:

int ATOsolenoid = 3;    //This is the output pin on the Arduino we are using
int FlushSolenoid = 4;  //This is the output pin on the Arduino we are using
int lowEye = 7;
int highEye = 8;
#define EXE_INTERVAL_1 5000
#define EXE_INTERVAL_2 10000

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  pinMode(ATOsolenoid, OUTPUT);    //Sets the pin as an output
  pinMode(FlushSolenoid, OUTPUT);  //Sets the pin as an output
  pinMode(lowEye, INPUT);
  pinMode(highEye, INPUT);
}

void loop() {
  digitalRead(lowEye);
  digitalRead(highEye);
  digitalRead(ATOsolenoid);
  bool waterIsLow = digitalRead(lowEye) == LOW;
  bool waterIsHigh = digitalRead(highEye) == HIGH;
  if (waterIsLow) {
    digitalWrite(ATOsolenoid, HIGH);
  }
  if (waterIsHigh) {
    digitalWrite(ATOsolenoid, LOW);
  }

  //Flush Solenoid
  unsigned long lastExecutedMillis_1 = 0;  // vairable to save the last executed time for code block 1
  unsigned long lastExecutedMillis_2 = 0;  // vairable to save the last executed time for code block 2
  unsigned long currentMillis = millis();
  if (digitalRead(ATOsolenoid == HIGH)) {
        digitalWrite(FlushSolenoid, HIGH);
      } 
  if (currentMillis - lastExecutedMillis_1 >= EXE_INTERVAL_1) {
    lastExecutedMillis_1 = currentMillis;  // save the last executed time
    digitalWrite(FlushSolenoid, HIGH);
  }
  if (currentMillis - lastExecutedMillis_2 >= EXE_INTERVAL_2) {
    lastExecutedMillis_2 = currentMillis;  // save the last executed time
    digitalWrite(FlushSolenoid, LOW);
  }
}

Your diagram perfectly represents the ideal outcome of this - I will attempt @gcjr's switch/case here shortly and report back. I can't thank you enough for all of the help on this!
