June in your desert garden

Posted on May 31, 2022 at 3:41 PM by Jesse Ruiz

Desert LandscapeGet ready for the arrival of daily hot, dry weather in June. By tending to chores and maintaining a regular irrigation schedule, your garden can look its best.


  • You can prune oleanders, lantana, bougainvillea and hibiscus.
  • Avoid pruning citrus foliage in the summer to prevent sunburn on trunk and primary branches.
  • Do not top trees; remove only dead and crossing branches.
  • Lightly thin excess interior growth of mesquites.
  • To keep roots cool and slow moisture evaporation, add a 3-inch-thick layer of mulch to roses, shrubs, and young trees.


  • Irrigation is important before temperatures top three digits daily.
  • Water deeply, but infrequently. Use a soil probe or a long screwdriver to check water penetration depth. They will move easily in wet soil but will not move much when they hit dry soil.
  • Soil should be damp down to 1½ feet for vegetables and 2 to 3 feet deep for trees.
  • To deter root rot, allow soil to dry out between waterings.


  • If citrus trees show an iron deficiency (young leaves looking yellowish), apply chelated iron.
  • If your plants need fertilizer in the summer, wet the soil both the day before and then immediately after you apply the fertilizer. That way, fertilizer will be more diluted and will not damage the roots.


Palms are a safe choice to plant or transplant in June.  Plant or move as early as possible in the month so they will have time to recover with good growth, responding to sunshine and deep irrigation.

  • Dig a planting hole twice as wide and just as deep as the existing rootball.
  • With twine, tie fronds up over the bud for protection. As new growth shows, snip the twine.
  • You can apply a root stimulator to the soil after planting to encourage fast rooting.

Sewer system upgrade will open the door for more housing

Posted on May 24, 2022 at 3:28 PM by Jesse Ruiz

Mecca aerial drone photoEngineering design of a project to improve sanitation infrastructure that will allow construction of more affordable housing in Mecca was approved May 24 by the CVWD Board of Directors.

A lift station near the intersection of Avenue 66 and Hammond Road in Mecca that pumps wastewater to Water Reclamation Plant 4 plant was built in 1993. It now needs upgrades to help meet sewer demands for planned and future developments in Mecca.

Dudek, a construction engineering company in Encinitas, was awarded the $683,981 contract for designing the Lift Station 55-11 Capacity Upgrade Project. Construction on the multi-year project is anticipated to start in fiscal year 2023-2024.

The new infrastructure will accommodate planned developments in Mecca, such as the Coachella Valley Housing Coalition’s Nuestro Orgullo project, College of the Desert East Campus expansion and other housing developments.

The board also:

  • Authorized an agreement with the Living Desert Zoo and Gardens and SCE for electric vehicle charging ports at the Living Desert.  The Living Desert, which sits on land owned by CVWD, plans to renovate its parking lot and install 64 charging ports.
  • Recognized the 20th anniversary of Auto Part Specialist II David Roberts.
  • Awarded a contract for $3.8 million  to Jones Brothers  Construction   for replacing 8,800 feet of leaking concrete pipe with PVC pipeline  along 58th Avenue from Van Buren Street to east of Harrison Street in Thermal. Improvements on this irrigation lateral will also include new metered delivery points, vaults, valves, meters and removing baffle stands.
  • Authorized staff to seek bids for construction of the Monroe Street Truck Sewer Project. The multi-year project will connect 33 homes, a church and a park in Thermal to CVWD’s sewer collection system.  Grants will fund the total cost of $2.6 million.
  • Approved an agreement with CDM Smith for design of the Water Reclamation Plant 10 (WRP 10) Headworks improvement Project. Constructed in 1974, replacement parts are not always available for headworks equipment. Total engineering design cost is $1.9 million.
  • Approved an agreement with West Yost Associates for $2.6 million to implement the CV-SNMP Development Workplan and execute the First Supplement to the Memorandum of Understanding regarding collaboration on the Coachella Valley Salt and Nutrient Management Plan.

Approved a nonpotable water agreement for Sunnylands, Rancho Mirage, which irrigates its golf course and landscape with water from its well.  Plans outline Sunnylands connecting to nonpotable water pipelines from WRP 10 expected to go under construction in summer 2024.
